  • How to display part of an image for the specific width and height?

    - by Brady Chu
    Recently I participated in a web project which has a huge large of images to handle and display on web page, we know that the width and height of images end users uploaded cannot be control easily and then they are hard to display. At first, I attempted to zoom in/out the images to rearch an appropriate presentation, and I made it, but my boss is still not satisfied with my solution, the following is my way: var autoResizeImage = function(maxWidth, maxHeight, objImg) { var img = new Image(); img.src = objImg.src; img.onload = function() { var hRatio; var wRatio; var Ratio = 1; var w = img.width; var h = img.height; wRatio = maxWidth / w; hRatio = maxHeight / h; if (maxWidth == 0 && maxHeight == 0) { Ratio = 1; } else if (maxWidth == 0) { if (hRatio < 1) { Ratio = hRatio; } } else if (maxHeight == 0) { if (wRatio < 1) { Ratio = wRatio; } } else if (wRatio < 1 || hRatio < 1) { Ratio = (wRatio <= hRatio ? wRatio : hRatio); } if (Ratio < 1) { w = w * Ratio; h = h * Ratio; } w = w <= 0 ? 250 : w; h = h <= 0 ? 370 : h; objImg.height = h; objImg.width = w; }; }; This way is only intended to limit the max width and height for the image so that every image in album still has different width and height which are still very urgly. And right at this minute, I know we can create a DIV and use the image as its background image, this way is too complicated and not direct I don't want to take. So I's wondering whether there is a better way to display images with the fixed width and height without presentation distortion? Thanks.

  • OnPage Load display one sentence - hide others

    - by Paul
    Hi I have created http://techavid.com/design/test3.html and when you load the page you see there are 3 images. The sun image is focused(in color), while the others are greyed out until clicked. That is how it should be for the images. Under each image you see a sentence 1st: Sun, 2nd: Airplane & 3rd: Nano, but when page loads you see all three sentences. How to make it so when page loads the first sentence underneath the active image (sun) shows only and the others do not show, they only show when clicked (though that works just need to figure out onpage load only show "1st: Sun")? thanks :) paul J.

  • Communicate between content script and options page

    - by Gaurang Tandon
    I have seen many questions already and all are about background page to content script. Summary My extension has an options page, and a content script. The content script handles the storage functionality (chrome.storage manipulation). Whenever, a user changes a setting in the options page, I want to send a message to the content script to store the new data. My code: options.js var data = "abcd"; // let data chrome.tabs.query({ active: true, currentWindow: true }, function (tabs) { chrome.tabs.sendMessage(tabs[0].id, "storeData:" + data, function(response){ console.log(response); // gives undefined :( }); }); content script js chrome.runtime.onMessage.addListener(function(request, sender, sendResponse) { // not working }); My question: Why isn't the approach not working? Is there any other (better) approach for this procedure.

  • Air XmlHttpRequest time out if remote server is offline?

    - by Seth
    I'm writing an AIR application that communicates with a server via XmlHttpRequest. The problem that I'm having is that if the server is unreachable, my asynchronous XmlHttpRequest never seems to fail. My onreadystatechange handler detects the OPENED state, but nothing else. Is there a way to make the XmlHttpRequest time out? Do I have to do something silly like using setTimeout() to wait a while then abort() if the connection isn't established? Edit: Found this, but in my testing, wrapping my xmlhttprequest.send() in a try/catch block or setting a value on xmlhttprequest.timeout (or TimeOut or timeOut) doesn't have any affect.

  • Displaying Google Calendar event data on FullCalendar

    - by aurealus
    I am using Google Calendar as a storage engine for a calendar system I am building, however, I am using a single Google user account with multiple calendars, i.e. each user on my system has their own calendar within the one user account. I'm able to create a calendar per user just fine, but I would like to have FullCalendar retrieve the events for display purposes, without manually getting the magic cookie url from Google Calendar settings. I would like to be able to retrieve it programmatically or 'proxy' the feed via an authenticated call to get event data that I'm doing in Django. $('#calendar').fullCalendar({ events: $.fullCalendar.gcalFeed( "http://www.google.com/calendar_url/" <-- or /my/event/feed/url ) });

  • Tinymce mceToggleEditor scroll/focus issue

    - by Lizard
    I have 50+ textareas that I am using tinyMCE with. Instead of loading each one I am just initialising them, then activing them later on request Initialisation tinyMCE.init({ mode : "none", theme : "advanced", theme_advanced_buttons1 : "", theme_advanced_buttons2 : "", theme_advanced_buttons3 : "", theme_advanced_toolbar_location : false, theme_advanced_toolbar_align : "left", theme_advanced_statusbar_location : false, theme_advanced_resizing : true, auto_focus : false }); Edit Observer $('ul span.edit-details').click(function () { var id = this.id; id = id.replace('edit-',''); tinyMCE.execCommand('mceToggleEditor',false,'editor-'+id); }); UPDATE I have also tried $('ul span.edit-details').click(function () { var id = this.id; id = id.replace('edit-',''); if($('#details-'+id).is(":hidden")) { $('#details-'+id).show(); tinyMCE.execCommand('mceAddControl',false,'editor-'+id); } else { $('#details-'+id).hide(); tinyMCE.execCommand('mceRemoveControl',false,'editor-'+id); } }); The problem I have is that when tinyMCE.execCommand('mceToggleEditor',false,'editor-'+id); fires the pages focuses/scrolls to that textarea, even if it is already in the viewport. Any suggestions on how to stop this? Thanks!

  • Xsl mime type problem

    - by savruk
    Hi, I have a busybox with lighttpd running on as http server. My problem is while firefox and opera can get the page with applied xsl, Arora(webkit) can not. Here is the script I use to get it work: <html> <head> <script> function loadXMLDoc(dname) { if (window.XMLHttpRequest) { xhttp=new XMLHttpRequest(); } else { xhttp=new ActiveXObject("Microsoft.XMLHTTP"); } xhttp.open("GET",dname,false); xhttp.send(""); return xhttp.responseXML; } function querySt(ji) { hu = window.location.search.substring(1); gy = hu.split("&"); for (i=0;i<gy.length;i++) { ft = gy[i].split("="); if (ft[0] == ji) { return ft[1]; } } } function displayResult() { xml=loadXMLDoc("sample.xml"); alert(xml)//Gives [object Document] $scan=querySt("scan"); $sub = querySt("sub"); xsl=loadXMLDoc("sample.xsl"); alert(xsl)//Gives Null // code for IE if (window.ActiveXObject) { ex=xml.transformNode(xsl); document.getElementById("example").innerHTML=ex; } // code for Mozilla, Firefox, Opera, etc. else if (document.implementation && document.implementation.createDocument) { xsltProcessor=new XSLTProcessor(); xsltProcessor.importStylesheet(xsl); xsltProcessor.setParameter(null,"scan",$scan) if($sub != ""){ xsltProcessor.setParameter(null,"sub",$sub) } resultDocument = xsltProcessor.transformToFragment(xml,document); document.getElementById("example").appendChild(resultDocument); } } </script> </head> <body onload="displayResult()"> <div id="example" ></div> </body> </html> I tried to see if it load xsl well and put an alert(xsl) but it gives null. Other browser can get xml and xsl files perfectly. What can be the problem? Thanks P.S: It runs well on my local server with all browser.

  • Python nested function scopes

    - by Thomas O
    I have code like this: def write_postcodes(self): """Write postcodes database. Write data to file pointer. Data is ordered. Initially index pages are written, grouping postcodes by the first three characters, allowing for faster searching.""" status("POSTCODE", "Preparing to sort...", 0, 1) # This function returns the key of x whilst updating the displayed # status of the sort. ctr = 0 def keyfunc(x): ctr += 1 status("POSTCODE", "Sorting postcodes", ctr, len(self.postcodes)) return x sort_res = self.postcodes[:] sort_res.sort(key=keyfunc) But ctr responds with a NameError: Traceback (most recent call last): File "PostcodeWriter.py", line 53, in <module> w.write_postcodes() File "PostcodeWriter.py", line 47, in write_postcodes sort_res.sort(key=keyfunc) File "PostcodeWriter.py", line 43, in keyfunc ctr += 1 UnboundLocalError: local variable 'ctr' referenced before assignment How can I fix this? I thought nester scopes would have allowed me to do this. I've tried with 'global', but it still doesn't work.

  • Unique element ID, even if element doesn't have one

    - by Robert J. Walker
    I'm writing a GreaseMonkey script where I'm iterating through a bunch of elements. For each element, I need a string ID that I can use to reference that element later. The element itself doesn't have an id attribute, and I can't modify the original document to give it one (although I can make DOM changes in my script). I can't store the references in my script because when I need them, the GreaseMonkey script itself will have gone out of scope. Is there some way to get at an "internal" ID that the browser uses, for example? A Firefox-only solution is fine; a cross-browser solution that could be applied in other scenarios would be awesome. Edit: If the GreaseMonkey script is out of scope, how are you referencing the elements later? They GreaseMonkey script is adding events to DOM objects. I can't store the references in an array or some other similar mechanism because when the event fires, the array will be gone because the GreaseMonkey script will have gone out of scope. So the event needs some way to know about the element reference that the script had when the event was attached. And the element in question is not the one to which it is attached. Can't you just use a custom property on the element? Yes, but the problem is on the lookup. I'd have to resort to iterating through all the elements looking for the one that has that custom property set to the desired id. That would work, sure, but in large documents it could be very time consuming. I'm looking for something where the browser can do the lookup grunt work. Wait, can you or can you not modify the document? I can't modify the source document, but I can make DOM changes in the script. I'll clarify in the question. Can you not use closures? Closuses did turn out to work, although I initially thought they wouldn't. See my later post. It sounds like the answer to the question: "Is there some internal browser ID I could use?" is "No."

  • Replacing text inside textarea without focus

    I want to replace selected text(or insert new text after cursor position if nothing is selected). The new text is entered from another textbox. I want to be able to insert new text without clicking first (focusing) in the textarea. meaning: first select text to replace inside textarea, then enter new text into the textbox and click the button. <textarea id='text' cols="40" rows="20"> </textarea> <div id="opt"> <input id="input" type="text" size="35"> <input type="button" onclick='pasteIntoInput(document.getElementById("input").value)' value="button"/> </div> function pasteIntoInput(text) { el=document.getElementById("text"); el.focus(); if (typeof el.selectionStart == "number"&& typeof el.selectionEnd == "number") { var val = el.value; var selStart = el.selectionStart; el.value = val.slice(0, selStart) + text + val.slice(el.selectionEnd); el.selectionEnd = el.selectionStart = selStart + text.length; } else if (typeof document.selection != "undefined") { var textRange = document.selection.createRange(); textRange.text = text; textRange.collapse(false); textRange.select(); } } Online example: link text

  • What is lifetime of lambda-derived implicit functors in C++ ?

    - by Fyodor Soikin
    The question is simple: what is lifetime of that functor object that is automatically generated for me by the C++ compiler when I write a lambda-expression? I did a quick search, but couldn't find a satisfactory answer. In particular, if I pass the lambda somewhere, and it gets remembered there, and then I go out of scope, what's going to happen once my lambda is called later and tries to access my stack-allocated, but no longer alive, captured variables? Or does the compiler prevent such situation in some way? Or what?

  • jQuery UI Dialog and Textarea Focus Issue

    - by Gimli
    I'm working on a modal comment system using jQuery and jQuery UI, but I'm having some issues with focus. I have a series of divs inside the modal to switch between Login and Add comment, as below: <div id="modal" title="Loading"> <div id="modalContent"></div> <div id="modalLogin"> <div class="loginBox"></div> <div class="addCommentBox"></div> <div class="commentReview"></div> </div> </div> Inside of the addCommentBox div, I've got the comment code: <form action="/comments/add" class="addCommentForm" name="addCommentForm" method="post"> <textarea name="content" class="addCommentContent"></textarea> <button value="Add Comment" type="submit" class="commentPost"/> <button value="Clear Comment" type="submit" id="clearComment"/> </form> The issue is that about half the time after opening the dialog the textarea inside the addCommentBox div doesn't react to keyboard inputs when selected. The mouse works correctly and will allow text to be selected, but keyboard control does nothing. I have no event listeners on the textarea. I've got some on the buttons, but they are targeting only the buttons. The only thing that happens in the HTML seems to be the fact that every time I click on the modal, the z-index increases for the overall modal div. I have set the addCommentBox div to have a z-index of 9999, greater than the z-index of the modal. Any suggestions or directions to research would be greatly appreciated. Thanks!

  • How to position an element so that it does not flow off the visible screen

    - by rjray
    I am creating pseudo-tooltips on a page that has a lot of "a" and "span" elements that have these tips associated with them. Everything in the creation of the element is fine, and it displays fine. However, since this is a page with a lot of data, as you get towards the bottom of the visual area the tooltips start to flow past the bottom edge of the window. My initial attempt to compensate for this with window.innerWidth/innerHeight didn't come out too well. I'm using jQuery for DOM manipulation (but not jQuery UI). Given the event itself, and the height and width of the tooltip (which I can get with getBoundingClientRect()), how can I position this element so that the bottom of the tooltip is never below the edge of the window?

  • Colour manipulation of custom tags in niceEdit HTML editor ( JS / DOM )

    - by Chris
    Hi, I would like to be able to highlight, during typing and in real time, certain custom tags in the format #tag_name# within the text of a nicEdit instance ( http://nicedit.com/ ). My current attempt to implement as close to this as possible revolves around using the blur event of the editor to highlight the tags once the editor loses focus. I then use the following logic to wrap the tags in a span with a highlight class.. htmlEditor.addEvent( "blur", function( ) { str = nicEditors.findEditor( "html_content" ).getContent( ); // Remove existing spans first, leaving just the tag ( this could mess up if the html has been edited directly ) str = str.replace( /(<span class=\"highlight\">)(.[^<]+)(<\/span>)/gi, "$2" ); // Then wrap all instances of a particular tag with the highlight span str = str.replace( /#tag_name#/gi, "<span class='highlight'>#tag_name#</span>" ); nicEditors.findEditor( "html_content" ).setContent( str ); }); This is not ideal as my actual text now contains unwanted spans ( I only want the highlighting for the user's input experience, not to be saved to the database ). Obviously I could remove the spans before saving the text but the whole system is currently open to errors ( If the html is directly edited then other text may get highlighted etc ). What I would like to know is.. Is there any way to directly change the colour of the tags in the editor or DOM without using a mechanism such as this? Perhaps a way of colouring the text in memory rather than changing the HTML ? Any ideas ? Regards Chris P
