Selenium problem locating by DOM

- by bartonlee

Hi, I'm trying to use the DOM to locate a form element in Selenium but I can't get it to work. Even if I use the example in the Selenium documentation it still fails, for example with this html... <html> <body> <form id="loginForm"> <input name="username" type="text" /> <input name="password" type="password" /> <input name="continue" type="submit" value="Login" /> <input name="continue" type="button" value="Clear" /> </form> </body> <html> and this command in the Selenium IDE... verifyElementPresent with target... dom=document.forms['loginForm'] I get [error] false in the log. The 'getElementById' example in the documentation does work, but none of the others. Can someone explain what I'm doing wrong here? Thanks.

Get last clicked item id

- by Peeter Kõbu

I have function like this: $(document).ready(function () { $("*").click(function () { alert($(this).attr('id').toString()); }); }); And on Page i have something like this: <asp:Content ID="BodyContent" runat="server" ContentPlaceHolderID="MainContent"> <script language="javascript" src="Scripts/jquery-1.4.1.js" type="text/javascript"></script> <div id="div1">Some stuff <div id="div2">Some other stuff <asp:Button ID="Button1" runat="server" Text="Button" /> <div id="div3">More stuff <asp:Button ID="Button2" runat="server" Text="Button" /> </div> </div> </div> If i click something it works fine, but it alerts me three times(or more). For example: I click button2. Alertbox appears with button2.id, then with div3.id, div2.id etc. It shows me all id's under that button. If i try to store this id to variable like this: var storedId = $(this).attr('id').toString(); it stores the last one.That means i get the id of form1. How can i get the first id? The id of clicked button or clicked label or whatever i have on my page.

jQuery menu animation

- by bomortensen

Hi Stackoverflow, I'm building a website where I'm using jQuery to animate a horizontal tabbed menu. What I want to achieve can be seen here: / link removed / If you hover/mouseover the "Link 1" tab, you'll see that a white div is expanding. Each of the tab menu items are a styled li-tag. What I want to do is, that when you hover/mouseover i.e. the "Link 2" tab, the white div contracts and then expands again with content related to "Link 2" instead of "Link 1". Also, the "Link 1" tab should be expanded by default (i.e. when you just entered the site) Does any of you jQuery ninjas out there know how to do this? What I currently have is this: <script type="text/javascript"> $(document).ready(function(){ var $div = $('#divtest'); var height = $div.height(); $div.hide().css({ height : 0 }); $('#forside').hover(function () { if ($div.is(':visible')) { $div.animate({ height: 0 }, { duration: 200, complete: function () { $div.hide(); } }); } else { $div.show().animate({ height : height }, { duration: 200 }); } return false; }); }); </script> Do I need to have 4 different div's which expands/contracts for every mouseover? If i'm not being clear about what my problem is, please say so and I'll try to elaborate :) Thanks in advance!

Changing iframe visibility on Mozilla not working

- by Honski

I've got a simple iframe that I want hidden until an event from that iframe is fire via easyXDM. It's working fine on Chrome, but somehow not on Mozilla. The event is being fired on both browsers, but only shows the iframe on Chrome. The only way to show the iframe on Mozilla is to call the same code using an onclick event. HTML: <a href="#" onclick="shower(); return false;">show frame (always working)</a> <br> <iframe src="testsite.php" width="600" height="424" scrolling="no" border="0" id="my-iframe3" style="visibility: hidden;" onload="scrollIFrame();" name="my-iframe3"> Javascript: function shower() { document.getElementById("my-iframe3").style.visibility="visible"; } var socket = new easyXDM.Socket( { onMessage: function(message, origin) { if (message == "hi") { socket.postMessage("do something"); } else if (message == "ready") { shower(); } } }); Both browsers receive the "ready" message.

PHP: Need a double check on an error in this small code

- by Josh K

I have this simple Select box that is suppose to store the selected value in a hidden input, which can then be used for POST (I am doing it this way to use data from disabled drop down menus) <body> <?php $Z = $_POST[hdn]; ?> <form id="form1" name="form1" method="post" action="test.php"> <select name="whatever" id="whatever" onchange="document.getElementById('hdn').value = this.value"> <option value="1">1Value</option> <option value="2">2Value</option> <option value="3">3Value</option> <option value="4">4Value</option> </select> <input type="hidden" name ='hdn' id="hdn" /> <input type="submit" id='submit' /> <?php echo "<p>".$Z."</p>"; ?> </form> </body> The echo call works for the last 3 options (2,3,4) but if I select the first one it doesnt output anything, and even if i change first one it still doesnt output anything. Can someone explain to me whats going on, I think it might be a syntax issue.

Jquery - removing an image before the client browser attempts to download it

- by ajbrun

Hi there, I wonder if anyone could help me with a problem I've been having. I have a number of large images available, but due to space limitations, I can't create multiple copies of these at various sizes. I have used PHP GD functions to resize the images to the sizes I need and output them to the browser. This works, but obviously takes some processing time, which therefore impacts pages load times. I'm fine with this, but I only want to show the image once it's fully loaded, and have a loading gif in its place until that time. I'm using jquery to do this. The problem I'm having is making the page functional whether the client has javascript enabled or not. If JS is not enabled, I want standard img tags to be outputted, otherwise the images are removed and replaced with a loading gif until they have been fully loaded. The link below shows a simple non-javascript unfriendly example of a what I want to do (try turning JS off): http://jqueryfordesigners.com/demo/image-load-demo.php I've been testing the basics using the code below. The attr() function will be replaced with something like remove(). This is just a test to make something happen to the image before the browser tries to load it. $(document).ready(function() { $( "#Thumbnails .thumbnail img" ).attr('src', '#'); }); In IE, this works correctly - the image source is replaced with "#" BEFORE the client browser gets a chance to start downloading the image. In firefox however, it downloads the image, and THEN changes the source. It seems to me that firefox is loading the jquery onready event later than it should. As far as I know, this should be executed before the standard onload event and before anything has started loading. If it helps, I'm testing it with a good number of images on screen (81). Am I doing something wrong?

I have a table which looks like this: <table id='t'> <thead> .... </thead> <tbody id='t_tbody'> </tbody> </table> thead is filled with content tbody is empty I want to use javascript to add this (for example) to t_tbody: <tr> <td>Name</td> <td>Points</td> <td>Information</td> </tr> How can I do this? I need a function which adds the above to t_tbody. Note that simply using document.getElementById('t_tbody').innerHtml+="<tr>...</tr>" works fine in FF, but not in IE. Also note that I need to use raw javascript (ie. no frameworks) for this project, as I am finishing a project which has already been mostly completed using raw javascript.

Jquery Works in FF but not IE at all

- by Shawn

I set up the SimpleModal plugin to work from our Ad server(Real 24/7). Essentially, attempting to make an interstitial ad. I serve a popupAd.js file from the Ad Server to our homepage(index.php), Here is the code for popupAd.js: $(document).ready(function() { $.modal('<iframe src="/welcomeAd.htm" height="525" width="562" style="border:0;" scrolling="no"/>', { closeHTML: "<a href='#' title='Close' align='right' style='color:#666>(X) Continue to website</a>", containerCss: { backgroundColor: '#fff', borderColor: "#0063dc", height: 525, padding: 0, width: 562, }, overlayCss:{ backgroundColor:"#fff", }, opacity:100, overlayClose: true }); }); This opens a modal window on the homepage which then loads welcomeAd.htm which contain nothing other than the ad call to the creative. Here is the code: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/1999/REC-html401-19991224/loose.dtd"> <html> <head> <title>Company Name</title>   </head> <body style="margin: 0; padding: 0; width: 100%; height: 100%"> <script type="text/javascript" language="JavaScript">  </script> </body> </html> This all works in FF but does nothing in IE, of which I am running IE7. Also, the closeHTML doesn't show up in Safari, though, the ad does.

Randomizing Div tags using Java Script

- by Andrew McNeil

I've looked around and have been able to find a piece of code that does the job but it doesn't work for all of my tags. I have a total of 8 Div tags that I want to randomize and this piece of code only allows me to randomize 7 of them. If I replace the 7 with an 8 it just shows everything in order. I don't work with Javascript very often and have hit a road block. Any help is greatly appreciated. <script type="text/javascript"> $(document).ready(function() { $(".workPiece").hide(); var elements = $(".workPiece"); var elementCount = elements.size(); var elementsToShow = 7; var alreadyChoosen = ","; var i = 0; while (i < elementsToShow) { var rand = Math.floor(Math.random() * elementCount); if (alreadyChoosen.indexOf("," + rand + ",") < 0) { alreadyChoosen += rand + ","; elements.eq(rand).show(); ++i; } } }); </script>

MS SQL - High performance data inserting with stored procedures

- by Marks

Hi. Im searching for a very high performant possibility to insert data into a MS SQL database. The data is a (relatively big) construct of objects with relations. For security reasons i want to use stored procedures instead of direct table access. Lets say i have a structure like this: Document MetaData User Device Content ContentItem[0] SubItem[0] SubItem[1] SubItem[2] ContentItem[1] ... ContentItem[2] ... Right now I think of creating one big query, doing somehting like this (Just pseudo-code): EXEC @DeviceID = CreateDevice ...; EXEC @UserID = CreateUser ...; EXEC @DocID = CreateDocument @DeviceID, @UserID, ...; EXEC @ItemID = CreateItem @DocID, ... EXEC CreateSubItem @ItemID, ... EXEC CreateSubItem @ItemID, ... EXEC CreateSubItem @ItemID, ... ... But is this the best solution for performance? If not, what would be better? Split it into more querys? Give all Data to one big stored procedure to reduce size of query? Any other performance clue? I also thought of giving multiple items to one stored procedure, but i dont think its possible to give a non static amount of items to a stored procedure. Since 'INSERT INTO A VALUES (B,C),(C,D),(E,F) is more performant than 3 single inserts i thought i could get some performance here. Thanks for any hints, Marks

Anybody can tell me why those code can make ie6 or ie8 compatible mode crash? PS:I know,there is so many ways to avoid this satuation, but I just want to know why. To avoid: Change class="wrapper"--class="wrapper2" or other != "wrapper" $('wrapper').style.overflow='visible'; -- setTimeout(function(){$('wrapper').style.overflow='visible';},10); Or remove any style , js operation... <!DOCTYPE html> <html> <head> <meta charset="utf-8" /> <style>.wrapper{width:975px;margin:60px auto 0}</style> </head> <body id="wrapper" style="overflow:hidden;"> <div id="overlay" style="position:absolute;"></div> <div class="wrapper"> <input type="text" id="input1"/> <a id="btn" href="javascript:;">test</a> </div> <script type="text/javascript"> $('btn').onclick = function(){ $('overlay').style.display='none'; $('wrapper').style.overflow='visible'; $("input1").focus(); } function $(s){ return document.getElementById(s); } </script> </body> </html>

Is SharePoint a good solution for me?

- by Pam Bullock

My company has many branches that use the same software suite that we've written for them. We're looking at SharePoint as a way to open a dialog with them about the software - reviews, change requests (not official ones, just for us to get an idea and for them to discuss amongst themselves what would be helpful). We would also like to utilize the document repository feature and possibly the blog. SharePoint is already available to us if we'd like to use it so that's why we're looking into it. I've done a lot of research and watched a lot of starter tutorials. It seems like it has what we're looking for. For those of you that know it well: Do you think it would be a good solution for us? Do you think it would be overkill? If so, Do you have an alternative suggestion? Are there other aspects of SharePoint that I haven't discovered yet that seems like it would be helpful for what we're doing? I will continue to research online but it's always great to hear the opinion of someone experienced with the product. Thanks so much! Pam

Regex to remove all but file name from links

- by Moasely

Hi, I am trying to write a regexp that removes file paths from links and images. href="path/path/file" to href="file" href="/file" to href="file" src="/path/file" to src="file" and so on... I thought that I had it working, but it messes up if there are two paths in the string it is working on. I think my expression is too greedy. It finds the very last file in the entire string. This is my code that shows the expression messing up on the test input: <script type="text/javascript" src="/javascripts/jquery.js"></script> <script type="text/javascript"> $(document).ready(function(){ var s = '<a href="one/keepthis"><img src="/one/two/keep.this"></a>'; var t = s.replace(/(src|href)=("|').*\/(.*)\2/gi,"$1=$2$3$2"); alert(t); }); </script> It gives the output: <a href="keep.this"></a> The correct output should be: <a href="keepthis"><img src="keep.this"></a> Thanks for any tips!

php / phpDoc - @return instance of $this class ?

- by searbe

How do I mark a method as "returns an instance of the current class" in my phpDoc? In the following example my IDE (Netbeans) will see that setSomething always returns a foo object. But that's not true if I extent the object - it'll return $this, which in the second example is a bar object not a foo object. class foo { protected $_value = null; /** * Set something * * @param string $value the value * @return foo */ public function setSomething($value) { $this->_value = $value; return $this; } } $foo = new foo(); $out = $foo->setSomething(); So fine - setSomething returns a foo - but in the following example, it returns a bar..: class bar extends foo { public function someOtherMethod(){} } $bar = new bar(); $out = $bar->setSomething(); $out->someOtherMethod(); // <-- Here, Netbeans will think $out // is a foo, so doesn't see this other // method in $out's code-completion ... it'd be great to solve this as for me, code completion is a massive speed-boost. Anyone got a clever trick, or even better, a proper way to document this with phpDoc?

Find class in table row

Hello. Take a look at this table: <table cellpadding="0" cellspacing="0" class="order_form"> <tr> <th>Amount</th> <th>Desc</th> <th>Price</th> <th>Total</th> </tr> <tr> <td><input type="text" class="order_count" /></td> <td> <span class="order_desc">Middagstallerken</span> </td> <td> <span class="order_price">1,15</span> </td> <td> <span class="order_each_total"></span> </td> </tr> [...] </table> Upon entering amount I need to select the class "order_price" and multiply it with the value of the input "order_count" and place it in "order_each_count". I have millions of these rows so I need to find the next class in the row. I have tried using some function like this but without result: <script type="text/javascript"> $(document).ready(function(){ $('.order_count').keyup(function() { var each_price = $(this).prevUntil("tr").find("span.order_price").text(); }); }); </script> I hope someone have a good solution :-)

$(window).load(function(){}); problem in Opera

Hello. I need to recalculate body's main div height, than wait while all content (images) loads and only than show it to site visitor. To achieve this i used jQuery and CSS //CSS looks like body {display: none;} /* div block height calculator */ function recalculateHeight(id, add){ var height = $(id).height(); if (height < 650) height = 650; if (add) height = height + add; $('#left_div').height(height); $('#center_div').height(height); $('#right_div').height(height); } //recalculate height when page is fully loaded $(document).ready(function(){ $(window).load(function(){ $('body').show(); recalculateHeight("#center_div"); }); }); Everything works fine in IE, Firefox, Safari. In Chrome height calculation works, but seems that body doesn't hides, because all images loads as usual they should. In Opera, both functions doesn't work. Not page is showed when all content is loaded, not page calculation works. You would better understand what I am talking about: Site where this problem is Thanks for Your response, brgds

Rails HTML Table update fields in mongo with AJAX

- by qwexar

I'm building a Rails app backed by mongodb using mongoid. It's a one page app, with a HTML table, every field for every row of which, needs to be editable without refreshing the page. This is your usual Rails view ( like many in rails casts ) showing a table with rows and columns containing data. For example. I'm showing cars, and showing their make, model and notes They way I'm doing this is by appending _id of a mongo document to every column and marking it's field name in html id too. Then I pick up the value for $("#id") and send it to rails controller via AJAX and run @car.update_attributes method accordingly. Currently, one of my rows looks like this. <tr> <td id=<%= car.id %>_make> <%= car.make %> </td> <td id=<%= car.id %>_model> <%= car.model %> </td> <td id=<%= car.id %>_notes> <%= car.notes %> </td> </tr> // my function which is called onChange for every column function update_attributes(id){ var id = id.split[0]; var attribute = id.split[1]; $.ajax("sending id and attribute to rails controller"); } Is there any built it Rails magic which would let me update only a field in a model without refreshing the page? or. Is there a Rails plugin for this?
