  • On Mac, two jpg's whose color should match do not

    - by Tim
    So I'm designing a myspace page and I have two images, one is a repeating bg image, and another is an image which loads on a layer above it, which acts as a header/masthead. For some reason, on Macs only, and only in the browser (tested in safari and ff), the masthead renders slightly darker than the repeating bg image, creating this color inconsistency. The block that extends up behind the album artwork is a solid box made with css which blocks some of myspace's standard content. It actually renders as the proper color, blending in well with the bottom portion of this image, which is the repeating part of the background, but becomes noticeable as it extends up, over the masthead, which is darker than it should be. Both images where created in GIMP and saved as jpg's using, as far as i can tell, the same settings. Here's the pic of what is going on: Screenshot - Click Me!!! Here is the code which controls this part of the design. <div class="masthead"><span></span></div> .masthead {width: 1600px; height: 1940px; background-image:url(http://www.sourtricks.com/myspace/bdww/myspace_bg09.jpg); position: absolute; margin-left: -800px; left: 50%; top: 0px; z-index: -1; overflow-x: hidden;} body.bodyContent{ margin: 0 !important; padding: 0 !important; background-color: 000000 !important; font-size: 1px; background-image: url(http://www.sourtricks.com/myspace/bdww/bg_repeat05.jpg); background-position: center bottom; _background-position: right bottom; background-attachment: scroll; background-repeat: repeat-y; z-index: -2; overflow-x: hidden; font-family: arial, sans-serif !important; } Any help would be much, much, much appreciated. Thanks for your time, Tim

  • CSS - changing the font color for a from select option in firefox

    - by Mick
    I'm building a website for my church, and I'm teaching myself all about web design along the way. http://www.wilmingtonchurchofgod.org/contact_us.html is the link where you can see my issue. If you look at that page in firefox, and you click the select part of the form (next to, "Who would you like to contact?") you will see that when you hover over a choice, the font is white. I have tried various things to fix this, but can't find a solution. This seems to be specific to Firefox. Here is the relevant CSS. input, textarea, select, option{ padding: 6px; border: solid 1px #E5E5E5; outline: 0; font: normal 13px/100% Verdana, Tahoma, sans-serif; width: 200px; background: #FFFFFF url(images/from-grad.jpg) left top repeat-x; background: -webkit-gradient(linear, left top, left 25, from(#FFFFFF), color-stop(4%, #EEEEEE), to(#FFFFFF)); background: -moz-linear-gradient(top, #FFFFFF, #EEEEEE 1px, #FFFFFF 25px); box-shadow: rgba(0,0,0, 0.15) 0px 0px 8px; -moz-box-shadow: rgba(0,0,0, 0.15) 0px 0px 8px; -webkit-box-shadow: rgba(0,0,0, 0.15) 0px 0px 8px; } option{ padding:0px; } textarea { width: 400px; max-width: 400px; height: 150px; line-height: 150%; } input:hover, textarea:hover, input:focus, textarea:focus{ border-color: #C9C9C9; -webkit-box-shadow: rgba(0, 0, 0, 0.15) 0px 0px 8px; -moz-box-shadow: rgba(0,0,0, 0.15) 0px 0px 8px; } option:hover, option:focus, select:hover, select:focus { color: black; border-color: #C9C9C9; -webkit-box-shadow: rgba(0, 0, 0, 0.15) 0px 0px 8px; -moz-box-shadow: rgba(0,0,0, 0.15) 0px 0px 8px; } Another side note is that I can't get any background gradient at all to show up on Google Chome (yet it does on Safari and they are supposed to use the same kit?) Any help with these two things would be greatly appreciated.

  • Popup browser incompability

    - by Cornelis
    I have a popup with drop down menus on it. I've scaled it down and simplified it for test purposes, but it still doesn't work the way I want/it should. <!DOCTYPE html> <html> <head> <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4/jquery.min.js"></script> <script type="text/javascript"> jQuery(document).ready(function(){ jQuery('.trigger').click(function(){ var picker = jQuery('.popup'); jQuery('<div></div>').css({ height: screen.height, width: screen.width, position: 'absolute', 'z-index': -1, top: picker.offset().top*-1, left: picker.offset().left*-1, border: '1px solid red' }).click(function(){ picker.trigger('focusout'); jQuery(this).hide(); }).prependTo(picker); picker.css('visibility', 'visible'); }); jQuery('.popup').live("focusout", function() { jQuery('.popup').fadeTo(500, 0.0, function() { jQuery('.popup').css('visibility', 'hidden'); jQuery('.popup').css('opacity', '1.0'); }); }); }); </script> </head> <body> <p> <input type=text class=trigger /> <div id=popup-div class=popup style="visibility: hidden; border: 1px solid red"> <select> <option>option1</option> </select> <p>Popup text</p> </div> </p> </body> When you click on the input field, a 'popup' appears, if you click outside the red border it fades away. If you click on the select option it shouldn't dissappear! However on this point, Chrome doesn't work the same as IE/FF/Opera/Safari, and makes the div dissappear. (Using Chrome 4.0.295.0) Does anybody knows a work-around for Chrome? Calling event.stopPropagation() on select elements did not work so far

  • JavaScript + Maths: Image zoom with CSS3 Transforms, How to set Origin? (with example)

    - by Sunday Ironfoot
    My Math skills really suck! I'm trying to implement an image zoom effect, a bit like how the Zoom works with Google Maps, but with a grid of fix position images. I've uploaded an example of what I have so far here: http://www.dominicpettifer.co.uk/Files/MosaicZoom.html (uses CSS3 transforms so only works with Firefox, Opera, Chrome or Safari) Use your mouse wheel to zoom in/out. The HTML source is basically an outer div with an inner-div, and that inner-div contains 16 images arranged using absolute position. It's going to be a Photo Mosaic basically. I've got the zoom bit working using CSS3 transforms: $(this).find('div').css('-moz-transform', 'scale(' + scale + ')'); ...however, I'm relying on the mouse X/Y position on the outer div to zoom in on where the mouse cursor is, similar to how Google Maps functions. The problem is that if you zoom right in on an image, move the cursor to the bottom/left corner and zoom again, instead of zooming to the bottom/left corner of the image, it zooms to the bottom/left of the entire mosaic. This has the effect of appearing to jump about the mosaic as you zoom in closer while moving the mouse around, even slightly. That's basically the problem, I want the zoom to work exactly like Google Maps where it zooms exactly to where your mouse cursor position is, but I can't get my head around the Maths to calculate the transform-origin: X/Y values correctly. Please help, been stuck on this for 3 days now. Here is the full code listing for the mouse wheel event: var scale = 1; $("#mosaicContainer").mousewheel(function(e, delta) { if (delta > 0) { scale += 1; } else { scale -= 1; } scale = scale < 1 ? 1 : (scale > 40 ? 40 : scale); var x = e.pageX - $(this).offset().left; var y = e.pageY - $(this).offset().top; $(this).find('div').css('-moz-transform', 'scale(' + scale + ')') .css('-moz-transform-origin', x + 'px ' + y + 'px'); return false; });

  • Browser detection Plugin?

    - by chobo2
    Hi I have a website that I made and I am planning to redo it. The current version of the site used a jquery callout plugin that did not fully work in IE6. This got me thinking about browser detection. At first I was just going to put the supported browsers on the home page but then today on Digg I saw some post about some jquery plugins and wordpress and in the article there was a plugin for detecting IE. So I started to look around for some browser detection plugins. I found a few of them but they where over the top like this one sevenup Its nice but it makes a huge popup and tells them to update. This one is better then another one I found where they basically forced the user to update or they could not continue on the site. So I found this one jquery plugin This one is pretty nice since it looks at the major browsers and does detection on them too expect for chrome which I noticed triggers and an outdated browser with this plugin. So I started to look at the jquery documentation to see if they had a browser detection for chrome this is when I saw that they "Deprecated" and now recommend "Support". So now I am just confused like "Support" seems to be good and I read many posts on this site saying you should use it. But then it does not support stuff like .png detection that might have been useful to me since of that plugin(however I probably will not be using the plugin anymore since I think the author just gave up on it). Plus I don't know if this is something I am looking for at this time. Like I am guessing with "Support" you use it to detect something that is not supported and then do some alternative thing for that browser? For me I am more looking for something to tell the user "Hey look I tested this browser in the these versions of Firefox(3.5+), IE(8+), Opera(9.5+),Chrome(Something), Safari(Something). If your not using these versions you may not being seeing the site how it was intended" Of course I would try to have something shorter then that message but that the gyst. I am also assuming that the site would work in future versions of these browsers. I still check to see if my site works(they usually do) and is half decent in IE 6 but I won't spend hours fixing stuff that might be off in older browsers like IE 6. I won't test my site in older version of other browsers like firefox since I would think the user have to the sense to update so no point testing firefox 2.0 or whatever. So is there a plugin that fits this description? Or can "Support" do what I want? Thanks

  • IE browser caching and the jQuery Form Plugin

    - by Harfleur
    Like so many lost souls before me, I'm floundering in the snake pit that is Ajax form submission and IE browser caching. I'm trying to write a simple script using the jQuery Form Plugin to Ajaxify Wordpress comments. It's working fine in Firefox, Chrome, Safari, et. al., but in IE, the response text is cached with the result that Ajax is pulling in the wrong comment. jQuery(this).ajaxSubmit({ success: function(data) { var response = $("<ol>"+data+"</ol>"); response.find('.commentlist li:last').hide().appendTo(jQuery('.commentlist')).slideDown('slow'); } }); ajaxSubmit sends the comment to wp-comments-post.php, which inelegantly spits back the entire page as a response. So, despite the fact that it's ugly as toads, I'm sticking the response text in a variable, using :last to isolate the most recent comment, and sliding it down in its place. IE, however, is returning the cached version of the page, which doesn't include the new comment. So ".commentlist li:last" selects the previous comment, a duplicate of which then uselessly slides down beneath the original. I've tried setting "cache: false" in the ajaxSubmit options, but it has no effect. I've tried setting a url option and tacking on a random number or timestamp, but it winds up being attached to the POST that submits the comment to the server rather than the GET that returns the response, and so has no effect. I'm not sure what else to try. Everything works fine in IE if I turn off browser caching, but that's obviously not something I can expect anyone viewing the page to do. Any help will be hugely appreciated. Thanks in advance! EDIT WITH A PROGRESS REPORT: A couple of people have suggested using PHP headers to prevent caching, and this does indeed work. The trouble is that wp-comments-post is spitting back the entire page when a new comment is submitted, and the only way I can see to add headers is to put them in the Wordpress post template, which disables caching on all posts at all times--not quite the behavior I'm looking for. Is there a way to set a php conditional--"if is_ajax" or something like that--that would keep the headers from being applied during regular pageloads, but plug them in if the page was called by an Ajax GET?

  • Problems with creating and using of delegate-protocols

    - by Flocked
    Hello, I have the problem that I have created a delegate protocol, but the necessary methods are not executed, although I have implemented the protocol in my header file. Here are the detailed explanation: I created an instance of my ViewController (TimeLineViewController), which will be displayed. This ViewController contains a UITableView, which in turn receives the individual Cells / Rows from one instance of my TableViewCell. So the ViewController creates an instance of TableCellView. The TableViewCell contains a UITextView, which contains web links. Now I want, that not safari opens the links, but my own built-in browser. Unfortunately TableViewCell can not open a new ViewController with a WebView, so I decided to create a delegate protocol. The whole thing looks like this: WebViewTableCellDelegate.h: @protocol WebViewTableCellDelegate -(void)loadWeb; @end Then I created a instance WebViewDelegate in the TableViewCell: id <WebViewTableCellDelegate> _delegate; In the .m of the TableViewCell: @interface UITextView (Override) @end @class WebView, WebFrame; @protocol WebPolicyDecisionListener; @implementation UITextView (Override) - (void)webView:(WebView *)webView decidePolicyForNavigationAction:(NSDictionary *)actionInformation request:(NSURLRequest *)request frame:(WebFrame *)frame decisionListener:(id < WebPolicyDecisionListener >)listener { NSLog(@"request: %@", request); [_delegate loadWeb]; } @end - (void)setDelegate:(id <WebViewTableCellDelegate>)delegate{ _delegate = delegate;} And in my TimeLineViewController I implemented the protocol with < and the loadWeb-metode: - (void)loadWeb{ WebViewController *web = [[WebViewController alloc] initWithNibName:nil bundle:nil]; web.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal; [self presentModalViewController: web animated:YES]; [web release]; } And when the instance of the TableViewCell will be created in the TimelineViewController: - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *MyIdentifier = @"MyIdentifier"; MyIdentifier = @"tableCell"; TableViewCell *cell = (TableViewCell *)[tableView dequeueReusableCellWithIdentifier:MyIdentifier]; if(cell == nil) { [[NSBundle mainBundle] loadNibNamed:@"TableViewCell" owner:self options:nil]; cell = tableCell;} [cell setDelegate:self]; //… } It is the first time I created a own delegate-protocol, so maybe there are stupid mistakes. Also I´m learnung Objective-C and programming generally only for 4 weeks. Thanks for your help! EDIT: I think i found the problem, but I dont know how to resolve it. I try to use [_delegate loadWeb]; in the subclass of the UITextView (because that is the only way i can react on the weblinks) and the subclass can´t use [_delegate loadWeb];. I tried this in a other methode and it worked.

  • Internet Explorer 8 + Deflate

    - by Andreas Bonini
    I have a very weird problem.. I really do hope someone has an answer because I wouldn't know where else to ask. I am writing a cgi application in C++ which is executed by Apache and outputs HTML code. I am compressing the HTML output myself - from within my C++ application - since my web host doesn't support mod_deflate for some reason. I tested this with Firefox 2, Firefox 3, Opera 9, Opera 10, Google Chrome, Safari, IE6, IE7, IE8, even wget.. It works with ANYTHING except IE8. IE8 just says "Internet Explorer cannot display the webpage", with no information whatsoever. I know it's because of the compression only because it works if I disable it. Do you know what I'm doing wrong? I use zlib to compress it, and the exact code is: /* Compress it */ int compressed_output_size = content.length() + (content.length() * 0.2) + 16; char *compressed_output = (char *)Alloc(compressed_output_size); int compressed_output_length; Compress(compressed_output, compressed_output_size, (void *)content.c_str(), content.length(), &compressed_output_length); /* Send the compressed header */ cout << "Content-Encoding: deflate\r\n"; cout << boost::format("Content-Length: %d\r\n") % compressed_output_length; cgiHeaderContentType("text/html"); cout.write(compressed_output, compressed_output_length); static void Compress(void *to, size_t to_size, void *from, size_t from_size, int *final_size) { int ret; z_stream stream; stream.zalloc = Z_NULL; stream.zfree = Z_NULL; stream.opaque = Z_NULL; if ((ret = deflateInit(&stream, CompressionSpeed)) != Z_OK) COMPRESSION_ERROR("deflateInit() failed: %d", ret); stream.next_out = (Bytef *)to; stream.avail_out = (uInt)to_size; stream.next_in = (Bytef *)from; stream.avail_in = (uInt)from_size; if ((ret = deflate(&stream, Z_NO_FLUSH)) != Z_OK) COMPRESSION_ERROR("deflate() failed: %d", ret); if (stream.avail_in != 0) COMPRESSION_ERROR("stream.avail_in is not 0 (it's %d)", stream.avail_in); if ((ret = deflate(&stream, Z_FINISH)) != Z_STREAM_END) COMPRESSION_ERROR("deflate() failed: %d", ret); if ((ret = deflateEnd(&stream)) != Z_OK) COMPRESSION_ERROR("deflateEnd() failed: %d", ret); if (final_size) *final_size = stream.total_out; return; }

  • div "top" bug IE and everything else. Big problem

    - by Victor
    Hi everyone. I am new in CSS so please help me in this problem. I hope to describe it wright. I am making div named content where my site content is. I made it with z-index:-1; so an image to be over this div. But in Chrome, FF and safari, content became inactive. I cant select text , click on link and write in the forms. So I tried with positive states in the z-index but IE don't know what this means. Damn. So I decided to make conditional div. Here is the code: .content { background:#FFF; width:990px; position:relative; float:left; top:50px; } .content_IE { background:#FFF; width:990px; position:relative; float:left; top: 50px; z-index:-1; } and here is the HTML: <!--[if IE 7]> <div class="content_IE" style="height:750px;"> <![endif]--> <div class="content" style="height:550px;"> Everything is fine with the z-index but the problem is that if there is no top in .content class everything looks fine in IE but there is no space in the other browsers. If i put back the top:50px; there onother 50px like padding in the .content_IE class. I mean that the page looks like I've put top:50px; and padding-top=50px;. I've try everything like margin-top:-50px; padding-top:-50px; and stuff like this but I am still in the circle. It look fine only if there is no top option in .content class. Please help.

  • mootools fx working except in ie9

    - by Craig
    This is my first attempt with Mootools, so I welcome a critique of the code. I have a dynamic list of images that expand on the 'click" event and contract on the 'mouseout' event. The code works fine in all browsers (FF, Safari, Chrome, even the smartphones) but not in IE9 (JS is enabled) Anyone with similar problem or solution? I plan to use a lightbox effect, downloading a larger & clearer image to the center of the page, instead of just resizing a small image. However, I am hesitant to attempt this, if there is problems with IE9. I have coded three image sizes with the upload commit, so the larger image is available for the lightbox, but, I don't see anything in mootools for a lightbox, or am I missing it? $i = 0; while($i < count($validate)) { <div class="validate"> <div class="validate_image_<?php echo $validate[$i]['validate_type']; ?>"> <div class="validate_image" id="validate_image_wrapper_<?php echo $i; ?>"> <?php if ($validate[$i]['validate_image_filename'] != '') { if (file_exists(UPLOAD_DIR . 'validate_image/' . str_replace('.', '_medium.', $validate[$i]['validate_image_filename']))) { echo '<img src="' . UPLOAD_URL . 'validate_image/' . str_replace('.', '_medium.', $validate[$i]['validate_image_filename']) . '" alt="Listing Image" />'; } else { echo '<img src="' . UPLOAD_URL .

  • How to download file into string with progress callback?

    - by Kaminari
    I would like to use the WebClient (or there is another better option?) but there is a problem. I understand that opening up the stream takes some time and this can not be avoided. However, reading it takes a strangely much more amount of time compared to read it entirely immediately. Is there a best way to do this? I mean two ways, to string and to file. Progress is my own delegate and it's working good. FIFTH UPDATE: Finally, I managed to do it. In the meantime I checked out some solutions what made me realize that the problem lies elsewhere. I've tested custom WebResponse and WebRequest objects, library libCURL.NET and even Sockets. The difference in time was gzip compression. Compressed stream lenght was simply half the normal stream lenght and thus download time was less than 3 seconds with the browser. I put some code if someone will want to know how i solved this: (some headers are not needed) public static string DownloadString(string URL) { WebClient client = new WebClient(); client.Headers["User-Agent"] = "Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US) AppleWebKit/532.5 (KHTML, like Gecko) Chrome/4.1.249.1045 Safari/532.5"; client.Headers["Accept"] = "application/xml,application/xhtml+xml,text/html;q=0.9,text/plain;q=0.8,image/png,*/*;q=0.5"; client.Headers["Accept-Encoding"] = "gzip,deflate,sdch"; client.Headers["Accept-Charset"] = "ISO-8859-2,utf-8;q=0.7,*;q=0.3"; Stream inputStream = client.OpenRead(new Uri(URL)); MemoryStream memoryStream = new MemoryStream(); const int size = 32 * 4096; byte[] buffer = new byte[size]; if (client.ResponseHeaders["Content-Encoding"] == "gzip") { inputStream = new GZipStream(inputStream, CompressionMode.Decompress); } int count = 0; do { count = inputStream.Read(buffer, 0, size); if (count > 0) { memoryStream.Write(buffer, 0, count); } } while (count > 0); string result = Encoding.Default.GetString(memoryStream.ToArray()); memoryStream.Close(); inputStream.Close(); return result; } I think that asyncro functions will be almost the same. But i will simply use another thread to fire this function. I dont need percise progress indication.

  • How a database is loaded into an application?

    - by Audel
    Hi All i need is a simple explanation on how does this function work I also attached a piece of php which I think is the one that retrieves the data from the database. Please correct me if I'm wrong Cheers. function loadDatabaseRecords () { // Mozilla/Safari if (window.XMLHttpRequest) { xmlHttpReq = new XMLHttpRequest(); } // IE else if (window.ActiveXObject) { xmlHttpReq = new ActiveXObject("Microsoft.XMLHTTP"); } alert ("To Server (Load Records):\n\najax-open-DB.php"); xmlHttpReq.open('GET', "ajax-open-DB.php", true); xmlHttpReq.onreadystatechange = loadDatabaseRecordsCallback; xmlHttpReq.send(null); } <?php $link = mysql_connect ("ipaddress", "localhost", "password"); mysql_select_db ("database1"); $query = "SELECT * from addressbook"; $result = mysql_query ($query); print "<table>"; print "<tr>"; print "<th>Firstname</th><th>Lastname</th><th>Address</th><th>Telephone</th>"; print "</tr>"; for ($i = 0; $i < mysql_num_rows ($result); $i ++) { $row = mysql_fetch_object ($result); print "<tr>"; print "<td>$row->firstname</td>"; print "<td>$row->lastname</td>"; print "<td>$row->address</td>"; print "<td>$row->telephone</td>"; print "</tr>"; } print "</table>"; mysql_close ($link); ?>

  • ASP.NET MVC 4/Web API Single Page App for Mobile Devices ... Needs Authentication

    - by lmttag
    We have developed an ASP.NET MVC 4/Web API single page, mobile website (also using jQuery Mobile) that is intended to be accessed only from mobile devices (e.g., iPads, iPhones, Android tables and phones, etc.), not desktop browsers. This mobile website will be hosted internally, like an intranet site. However, since we’re accessing it from mobile devices, we can’t use Windows authentication. We still need to know which user (and their role) is logging in to the mobile website app. We tried simply using ASP.NET’s forms authentication and membership provider, but couldn’t get it working exactly the way we wanted. What we need is for the user to be prompted for a user name and password only on the first time they access the site on their mobile device. After they enter a correct user name and password and have been authenticated once, each subsequent time they access the site they should just go right in. They shouldn’t have to re-enter their credentials (i.e., something needs to be saved locally to each device to identify the user after the first time). This is where we had troubles. Everything worked as expected the first time. That is, the user was prompted to enter a user name and password, and, after doing that, was authenticated and allowed into the site. The problem is every time after the browser was closed on the mobile device, the device and user were not know and the user had to re-enter user name and password. We tried lots of things too. We tried setting persistent cookies in JavaScript. No good. The cookies weren’t there to be read the second time. We tried manually setting persistent cookies from ASP.NET. No good. We, of course, used FormsAuthentication.SetAuthCookie(model.UserName, true); as part of the form authentication framework. No good. We tried using HTML5 local storage. No good. No matter what we tried, if the user was on a mobile device, they would have to log in every single time. (Note: we’ve tried on an iPad and iPhone running both iOS 5.1 and 6.0, with Safari configure to allow cookies, and we’ve tried on Android 2.3.4.) Is there some trick to getting a scenario like this working? Or, do we have to write some sort of custom authentication mechanism? If so, how? And, what? Or, should we use something like claims-based authentication and WIF? Or??? Any help is appreciated. Thanks!

  • jQuery UI dialog + WebKit + HTML response with script

    - by Anthony Koval'
    Once again I am faced with a great problem! :) So, here is the stuff: on the client side, I have a link. By clicking on it, jQuery makes a request to the server, gets response as HTML content, then popups UI dialog with that content. Here is the code of the request-function: function preview(){ $.ajax({ url: "/api/builder/", type: "post", //dataType: "html", data: {"script_tpl": $("#widget_code").text(), "widgets": $.toJSON(mwidgets), "widx": "0"}, success: function(data){ //console.log(data) $("#previewArea").dialog({ bgiframe: true, autoOpen: false, height: 600, width: 600, modal: true, buttons: { "Cancel": function() { $(this).dialog('destroy'); } } }); //console.log(data.toString()); $('#previewArea').attr("innerHTML", data.toString()); $("#previewArea").dialog("open"); }, error: function(){ console.log("shit happens"); } }) } The response (data) is: <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <script type="text/javascript">var smakly_widget_sid = 0 ,widgets = [{"cols": "2","rows": "2","div_id": "smakly_widget","wid": "0","smakly_style": "small_image",}, ] </script> <script type="text/javascript" src="/media/js/smak/smakme.js"></script> </head> <body> preview <div id="smakly_widget" style="width:560px;height:550px"> </div> </body> </html> As you see, there is a script to load: smakme.js, somehow it doesn't execute in WebKit-based browsers (I tried in Safari and Chrome), but in Firefox, Internet Explorer and Opera it works as expected! Here is that script: String.prototype.format = function(){ var pattern = /\{\d+\}/g; var args = arguments; return this.replace(pattern, function(capture){ return args[capture.match(/\d+/)]; }); } var turl = "/widget" var widgetCtrl = new(function(){ this.render_widget = function (w, content){ $("#" + w.div_id).append(content); } this.build_widgets = function(){ for (var widx in widgets){ var w = widgets[widx], iurl = '{0}?sid={1}&wid={2}&w={3}&h={4}&referer=http://ya.ru&thrash={5}'.format( turl, smakly_widget_sid, w.wid, w.cols, w.rows, Math.floor(Math.random()*1000).toString()), content = $('<iframe src="{0}" width="100%" height="100%"></iframe>'.format(iurl)); this.render_widget(w, content); } } }) $(document).ready(function(){ widgetCtrl.build_widgets(); }) Is that some security issue, or anything else?

  • Using JavaScript to parse an XML file

    - by Chris Clouten
    I am new to Stack OverFlow and coding in general. I am trying to take an XML file and render it in the browser using JavaScript. I have looked around at some sample code of how to do this and came up with the following code: <!DOCTYPE html> <html> <body> <script> if (window.XMLHttpRequest) {// code for IE7+, Firefox, Chrome, Opera, Safari xmlhttp=new XMLHttpRequest(); } else {// code for IE6, IE5 xmlhttp=new ActiveXObject("Microsoft.XMLHTTP"); } xmlhttp.open("GET","social.xml",false); xmlhttp.send(); xmlDoc=xmlhttp.responseXML; document.write("<table border='1'>"); var x=xmlDoc.getElementsByTagName("CD"); for (i=0;i<x.length;i++) { document.write("<tr><td>"); document.write(x[i].getElementsByTagName("c_id")[0].childNodes[0].nodeValue); document.write("</td><td>"); document.write(x[i].getElementsByTagName("facebook_id")[0].childNodes[0].nodeValue); document.write("</td></tr>"); } document.write("</table>"); </script> </body> </html> Anyway, when I run this on my local server none of the data that I am trying to display in the table appears. My .html file and .xml file are in the same folder, so I believe I have the correct file pathway. I could just be making a rookie mistake here, but I can't for the life of me figure out why a table listing the c_id and facebook_id values is not being created. I looked around for answers and haven't been able to find any. Any help would be greatly appreciated. Thanks!

  • jQuery reports incorrect element height in Firefox iframe

    - by Augustus
    Here a short test to demonstrate my problem. I have a page that loads an iframe: <html> <head> <title></title> <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.js"></script> </head> <body> <iframe id="iframe" src="box.html" style="width: 100px; height: 100px"></iframe> <script> $('#iframe').bind('load', function () { var div = $(this).contents().find('div'); alert(div.height()); alert(div.innerHeight()); alert(div.outerHeight()); alert(div.outerHeight(true)); }); </script> </body> </html> The iframe (box.html) contains a single styled div: <html> <head> <title></title> <style> div { height: 50px; width: 50px; margin: 5px; padding: 5px; border: 2px solid #00f; background-color: #f00; } </style> </head> <body> <div></div> </body> </html> The four alerts should return 50, 60, 64 and 74, respectively. This works as expected in Safari and Chrome. In FF 3.5.1, they all return 64. This is wrong. Does anyone know how I can force FF/jQuery to return the correct values?

  • Providing updating suggestions list with javascript, php and ajax

    - by user1104854
    I'm trying to modify this example on making a live updating list to integrate it with my API. So, instead of using GET on the page with the form, I'd like to send it to that page via a function call. So, here's my form // message.php //function to display the hint sent from gethint.php function message_hint($hint){ echo $hint; } //displays the form for sending messages function send_message_form($to_user,$title,$message){ include 'gethint.php'; ?> <table> <form name = "send_message" method="post"> <td>Send A Message</td> <tr><td>To:</td><td><input type = "text" size="50" name="to_user" id = "to_user" value ="<? echo $to_user; ?>" onkeyup="showHint(this.value)"></td></tr> <tr><td>Title:</td><td><input type = "text" size="50" name="message_title"></td></tr> <tr><td>Message:</td><td><textarea rows="4" cols="50" name="message_details"></textarea></td></tr> <tr><td><input type="submit" name="submit_message"></td></tr> </table> </form> <? } Here's the head of message.php <head> <script> function showHint(str){ var to_user = document.getElementById("to_user").value //to_user is the id of the textbox if (str.length==0){ to_user.innerHTML=""; return; } if (window.XMLHttpRequest){// code for IE7+, Firefox, Chrome, Opera, Safari xmlhttp=new XMLHttpRequest(); }else{// code for IE6, IE5 xmlhttp=new ActiveXObject("Microsoft.XMLHTTP"); } xmlhttp.onreadystatechange=function(){ if (xmlhttp.readyState==4 && xmlhttp.status==200){ alert(to_user) //properly displays the name via alert box to_user.innerHTML=xmlhttp.responseText; } } xmlhttp.open("GET","gethint.php?q="+to_user,true); xmlhttp.send(); } </script> </head> The page gethint.php is exactly the same, aside from this at the bottom. //echo $response //this was the original output $message = new messages; $message->message_hint($response);

  • Infinite Refresh Loop in Firefox 3.0

    - by Martin Gordon
    I'm having a strange issue with my Javascript in Firefox 3.0.x. In Firefox 3.0.12, the page constantly reloads as soon as the list body is loaded. Neither Firefox 3.5, Safari 4 nor Chrome 5 (all on Mac) experience this issue. EDIT: I've created an isolated example rather than pulling this from my existing code. test.js function welcomeIndexOnLoad() { $("#options a").live('click', function () { optionClicked($(this), "get_list_body.html"); return false; }); $(document).ready(function() { optionClicked(null, "get_list_body.html"); }); } function optionClicked(sender, URL) { queryString = ""; if (sender != null) { queryString = $(sender).attr("rel"); } $("#list_body").load(URL + "?" + queryString, function(resp, status, AJAXReq) { console.log(resp); console.log("" + status); location.hash = queryString; }); }? test.html <html> <head> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.js"></script> <script type="text/javascript" src="test.js"></script> <script> welcomeIndexOnLoad(); </script> </head> <body> <div id="container"> Outside of list body. <div id="list_body"> </div> </div> </body> </html> get_list_body.html <h3> <div id="options"> <a href="#" rel="change_list">Change List</a> </div> <ul> <li>li</li> </ul> jQuery line 5252 (an xhr.send() call) shows up in the console as soon as the page reloads: xhr.send( type === "POST" || type === "PUT" || type === "DELETE" ? s.data : null );

  • Setting background-image with javascript

    - by Mattoe3k
    In chrome, safari, and opera setting the background image to an absolute reference such as: "/images/image.png" changes it to "http://sitepath/images/image.png". It does not do this in firefox. Is there any way to avoid this behavior, or is it written into the browser's javascript engine? Using jquery to set the background-image also does this problem. The problem is that I am posting the HTML to a php script that needs the urls in this specific format. I know that setting the image path relative fixes this, but I can't do that. The only other alternative would be to use a regexp. to convert the urls. Thanks. Test this in firefox, and chrome / webkit browser: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>Untitled Document</title> </head> <body> <div style="height:400px;width:400px;background-image:url(/images/images/logo.gif);"> </div> <br /> <br /> <div id="test" style="height:400px;width:400px;"> </div> <script type="text/javascript" src="/javascripts/jquery.js"></script> <script type="text/javascript"> $(document).ready(function(){ $("#test").css('background-image',"url(/images/images/logo.gif)"); alert(document.getElementById('test').style.backgroundImage); }); </script> </body> </html>

  • jQuery: load refuses to get dynamic content in IE6

    - by user260157
    jQuery refuses to load my dynamic content in IE6. All in FireFox & Safari works fine. Only IE6 is being a pain. When I try the a html with <p>Hello World</p> that works. Properly. But when loading a PHP it doesn't work! As you can see it's doing multiple things. <script type="text/javascript"> // When the document is ready set up our sortable with it's inherant function(s) $(document).ready(function() { // Sort list & amend in database function sortTableMenuAndReload() { var order = $('#menuList').sortable('serialize'); $.post("PLUGINS/SortableMenu/process-sortable.php",order); $("#menuList").load("PLUGINS/SortableMenu/sortableMenu_ajax.php"); } function sortTableOrder() { var order = $('#menuList').sortable('serialize'); $.post("PLUGINS/SortableMenu/process-sortable.php",order); } function sortTableOrderAndRemove(removeID) { $('#listItem_'+removeID).remove(); var order = $('#menuList').sortable('serialize'); $.post("PLUGINS/SortableMenu/process-sortable.php",order); $("#menuList").load("PLUGINS/SortableMenu/sortableMenu_ajax.php"); } $("#menuList > li > .remove").live('click', function () { var removeID = $(this).attr('id'); $.ajax({ type: 'post', url: 'PLUGINS/SortableMenu/removeLine.php', data: 'id='+removeID, success: sortTableOrderAndRemove(removeID) }); }); $("#menuList > li > .publish").live('click', function () { var publishID = $(this).attr('id'); $.ajax({ type: 'post', url: 'PLUGINS/SortableMenu/publishLine.php', data: 'id='+publishID, success: sortTableOrder }); }); $('#new_documents > li').draggable({ addClasses: false, helper:'clone', connectToSortable:'#menuList' }); $("#menuList").droppable({ addClasses: false, drop: function() { var clone = $("#menuList > li#newArticleTYPE1"); $(clone).attr("id","listItem_newArticleTYPE1"); } }); $("#menuList").sortable({ opacity: 0.6, handle : '.handle, .remove', update : sortTableMenuAndReload }); }); </script>
