  • Efficient way to copy a collection of Nodes, treat them, and then serialize?

    - by Danjah
    Hi all, I initially thought a regex to remove YUI3 classNames (or whole class attributes) and id attributes from a serialized DOM string was a sound enough approach - but now I'm not sure, given various warnings about using regex on HTML. I'm toying with the idea of making a copy of the DOM structure in question, performing: var nodeStructure = Y.one('#wrap').all('*'); // A YUI3 NodeList // Remove unwanted classNames.. I'd need to maintain a list of them to remove :/ nodeStructure.removeClass('unwantedClassName'); and then: // I believe this can be done on a NodeList collection... nodeStructure.removeAttribute('id'); I'm not quite sure about what I'd need to do to 'copy' a collection of Nodes anyway, as I don't actually want to do the above to my living markup, as its only being saved - not 'closed' or 'exited', a user could continue to change the markup, and then save again. The above doesn't make a copy, I know. Is this efficient? Is there a better way to 'sanitize' my live markup of framework additions to the DOM (and maybe other things too at a later point), before saving it as a string? If it is a good approach, what's a safe way to go about copying my collection of Nodes for safe cleaning? Thanks! d

  • How to customize Bootstrap typeahead layout/function for more than just text?

    - by Loolooii
    I'm working on a search functionality for my website and I'm using Bootstrap's typeahead to show the results. So far so good. But what I want is to extend the function so that I could add an image and some other item, say description, etc. According to this post, that is possible: custom typeahead. Basically I need something like this as each result item: <div class="resultContainer"> <div class="resultImage"><img /></div> <div class="resultDesc"></div> <div class="resultLabel"></div> </div> Now it's: <li><a href="#"></a></li> And this doesn't even work with a longer text than the width of the typeahead. So the text doesn't go to the next line and hence doesn't fit the <li>. How can I use the the custom layout I want? (btw I have an array of arrays of results. Each sub-array contains img, desc, etc.). This is what I have right now: Thanks in advance.

  • jQuery - How can I temporarily disable the onclick event listener after the event has been fired?

    - by aldux
    How can I temporarily disable the onclick event listener, (jQuery preferred), after the event has been fired? Example: After the user clicks on the button and fires this function below, I want to disabled the onclick listener, therefore not firing the same command to my django view. $(".btnRemove").click(function(){ $(this).attr("src", "/url/to/ajax-loader.gif"); $.ajax({ type: "GET", url: "/url/to/django/view/to/remove/item/" + this.id, dataType: "json", success: function(returned_data){ $.each(returned_data, function(i, item){ // do stuff }); } }); Thanks a lot, Aldo

  • Search row with highest number of cells in a row with colspan

    - by user593029
    What is the efficient way to search highest number of cells in big table with numerous colspan (merge cells ** colspan should be ignored so in below example highest number of cells is 4 in first row). Is it js/jquery with reg expression or just the loop with bubble sorting. I got one link as below explainig use of regex is it ideal way ... can someone suggest pseudo code for this. High cpu consumption due to a jquery regex patch <table width="156" height="84" border="0" > <tbody> <tr style="height:10px"> <td width="10" style="width:10px; height:10px"/> <td width="10" style="width:10px; height:10px"/> <td width="10" style="width:10px; height:10px"/> <td width="10" style="width:10px; height:10px"/> </tr> <tr style="height:10px"> <td width="10" style="width:10px; height:10px" colspan="2"/> <td width="10" style="width:10px; height:10px"/> <td width="10" style="width:10px; height:10px"/> </tr> <tr style="height:10px"> <td width="10" style="width:10px; height:10px"/> <td width="10" style="width:10px; height:10px"/> <td width="10" style="width:10px; height:10px" colspan="2"/> </tr> <tr style="height:10px"> <td width="10" style="width:10px; height:10px" colspan="2"/> <td width="10" style="width:10px; height:10px"/> <td width="10" style="width:10px; height:10px"/> </tr> </tbody> </table>

  • Element.appendChild() hosed in IE .. workaround? (related to innerText vs textContent)

    - by Rowe Morehouse
    I've heard that using el.innerText||el.textContent can yield unreliable cross-browswer results, so I'm walking the DOM tree to collect text nodes recursively, and write them into tags in the HTML body. What this script does is read hash substring valus from the window.location and write them into the HTML. This script is working for me in Chrome & Firefox, but choking in IE. I call the page with an URL syntax like this: http://example.com/pagename.html#dyntext=FOO&dynterm=BAR&dynimage=FRED UPDATE UPDATE UPDATE Solution: I moved the scripts to before </body> (where they should have been) then removed console.log(sPageURL); and now it's working in Chrome, Firefox, IE8 and IE9. This my workaround for the innerText vs textContent crossbrowser issue when you are just placing text rather than getting text. In this case, getting hash substring values from the window.location and writing them into the page. <html> <body> <span id="dyntext-span" style="font-weight: bold;"></span><br /> <span id="dynterm-span" style="font-style: italic;"></span><br /> <span id="dynimage-span" style="text-decoration: underline;"></span><br /> <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.8/jquery.min.js"></script> <script> $(document).ready(function() { var tags = ["dyntext", "dynterm", "dynimage"]; for (var i = 0; i < tags.length; ++i) { var param = GetURLParameter(tags[i]); if (param) { var dyntext = GetURLParameter('dyntext'); var dynterm = GetURLParameter('dynterm'); var dynimage = GetURLParameter('dynimage'); } } var elem = document.getElementById("dyntext-span"); var text = document.createTextNode(dyntext); elem.appendChild(text); var elem = document.getElementById("dynterm-span"); var text = document.createTextNode(dynterm); elem.appendChild(text); var elem = document.getElementById("dynimage-span"); var text = document.createTextNode(dynimage); elem.appendChild(text); }); function GetURLParameter(sParam) { var sPageURL = window.location.hash.substring(1); var sURLVariables = sPageURL.split('&'); for (var i = 0; i < sURLVariables.length; i++) { var sParameterName = sURLVariables[i].split('='); if (sParameterName[0] == sParam) { return sParameterName[1]; } } } </script> </body> </html> FINAL UPDATE If your hash substring values require spaces (like a linguistic phrase with three words, for example) then separate the words with the + character in your URI, and replace the unicode \u002B character with a space when you create each text node, like this: var elem = document.getElementById("dyntext-span"); var text = document.createTextNode(dyntext.replace(/\u002B/g, " ")); elem.appendChild(text); var elem = document.getElementById("dynterm-span"); var text = document.createTextNode(dynterm.replace(/\u002B/g, " ")); elem.appendChild(text); var elem = document.getElementById("dynimage-span"); var text = document.createTextNode(dynimage.replace(/\u002B/g, " ")); elem.appendChild(text); Now form your URI like this: http://example.com/pagename.html#dyntext=FOO+MAN+CHU&dynterm=BAR+HOPPING&dynimage=FRED+IS+DEAD

  • iPad doesn't trigger resize event going from vertical to horizontal?

    - by dclowd9901
    Has anyone noticed this behavior? I'm trying to write a script that will trigger upon a resize. It works fine on normal browsers, works fine on iPhone, but on iPad, will only trigger going from horizontal to vertical viewport, not vice versa. Here's the code: $(window).resize( function() { var agent=navigator.userAgent.toLowerCase(); var is_iphone = ((agent.indexOf('iphone') != -1)); var is_ipad = ((agent.indexOf('ipad') != -1)); if(is_iphone || is_ipad){ location.reload(true); } else { /* Do stuff. */ }; });

  • Showing same dfp ads in a single page web application

    - by mivaas19
    I have a single page web application which contains dfp ads. I have two dfp adunits that Iam firing and they are placed in between the content which is a list of articles for a particular category. When I click on another category,it just loads articles for different category(doesnt change the url in address bar) and triggers the same ads. So this is like triggering the ads on the same page. The ads dont show up the second time and this is because you cant use the same adunits on the same page. Since I cannot use the refresh function provided by dfp since my DOM is reconstructed everytime, is there any way I can do this?.

  • How would one rotate an image around itself using Canvas?

    - by Wolfr
    I'm having trouble roating an image around itself using Canvas. Since you can't rotate an image you have to rotate the canvas: if I rotate the canvas by a degree the origin around which I want to rotate changes. I don't get how to track this change. This is my current code: http://pastie.org/669023 And a demo is at http://preview.netlashproject.be/cog/ If you want to give things a shot the zipped up code and image is at http://preview.netlashproject.be/cog/cog.zip

  • jQuery plugin: Validation can't be customized without setting all fields to 'required'?

    - by rasx
    I've spent the day looking at jQuery plugin: Validation by Jörn Zaefferer. I notice that it works fine as long as you call the validate() method without options. In my little squalid world, as soon as I add options, like errorPlacement, I notice that validation ignores form fields that are not marked required. I also notice that many, many demos mark all fields required---or do not pass options. Am I writing about anything familiar here? Or should I astral project to a parallel universe?

  • Google Chrome Extension : Port: Could not establish connection. Receiving end does not exist

    - by tcornelis
    I have been looking for an answer for almost a week now, but having read all the stackoverflow items i can't seem to find a solution that is working for me. The error that i'm having is : Port: Could not establish connection. Receiving end does not exist. lastError:30 set lastError:30 dispatchOnDisconnect messaging:277 folder layout : img developer_icon.png js sidebar.js main.js jquery-2.0.3.js manifest.json my the manifest.json file looks something like this (it is version 2) :` "browser_action": { "default_icon": "./img/developer_icon.png" }, "content_scripts": [ { "matches": ["*://*/*"], "js": ["./js/sidebar.js"], "run_at": "document_end" } ], "background" : { "scripts" : ["./js/main.js","./js/jquery-2.0.3.js"] }, I want to handle the user clicking the extension icon so i could inject a sidebar in the existing website (because the extension i would like to develop requires that amount of space). So in main.js : chrome.browserAction.onClicked.addListener(function(tab) { chrome.tabs.getSelected(null, function(tab){ chrome.tabs.sendMessage( //Selected tab id tab.id, //Params inside a object data {callFunction: "toggleSidebar"}, //Optional callback function function(response) { console.log(response); } ); }); }); and in sidebar.js : chrome.runtime.onMessage.addListener(function(req,sender,sendResponse){ console.log("sidebar handling request"); toggleSidebar(); }); but i'm never able to see the console.log in my console because of the error. Does someone know what i did wrong? Thanks in advance!

  • jQuery resizable() dynamic maxWidth option

    - by Vitaliy Isikov
    I have 3 columns that are resizable. When one is made wider, the one to it's left is made smaller. Essentially there are only 2 handles. Left col and Mid col. So when Mid col is made thinner, Right col expands accordingly. All three of them are contained with a 900px parent div, so the sum of all three is always 900. They have max and min widths set statically. My issue is that if you take the left handle and move it all the way to the right you're still able to use the right handle and expand the mid col past the edge of the parent div. I thought of a way to solve that issue by writing up a function that checks the widths of the columns and then subtracts left and right columns from the parent div width, I called it mWid. This leaves me with the number I want to set as the maxWidth for Mid col. Now the issue is that mWid is not gettings updated for here "maxWidth: mWid" Here is what the function for the right handle looks like: $(function() { $("#midResizable").resizable({ handles: 'e', containment: '#container', maxWidth: mWid, // gets set once, but doesn't update! WHY? minWidth: 195, resize: function(event, ui) { contWidth = $('#container').width() newWidth = $(this).width() leftWidth = $('#leftResizable').width() rightWidth = $('#rightResizable').width() $("#rightResizable").css("width", (contWidth-15)-(newWidth)-(leftWidth)+"px"); checkWid() } }); }); function checkWid() { rightWidth = $('#rightResizable').width() leftWidth = $('#leftResizable').width() contWidth = $('#container').width() mWid = (contWidth-15)-(rightWidth)-(leftWidth) }

  • HTML 5 drag-drop into wysiwyg editor in Firefox

    - by einarq
    I have a wysiwyg editor using the HTML 5 drag-drop api to allow the user to place widgets within the page they are editing. When the OnDrop event fires, I prevent the default event, and insert some html within the editor that represents the widget they inserted. I use execCommand("inserthtml", false, html) for this in Firefox. This works fine in IE, but in Firefox the html is not placed in the location where it was dropped. It always gets placed in the location where the previous selection was, which leads me to believe that cancelling the OnDrop event to override the default drop also cancels the selection change. Any ideas on how to solve this? Thanks!

  • How can I highlight the line of text that is closest to the mouse?

    - by Aaron Digulla
    I have a long text and I'd like to offer the user a reading help: The current line should be highlighted. To make it easier, I'll just use the Y coordinate of the mouse (this way, the mouse pointer isn't going to get in the way). I have a big DIV with the id content which fills the whole width and a small DIV with the class content for the text (see here for an example). I'm using jQuery 1.4. How can I highlight the line of text that is closest to the current mouse position?

I guess something with z-index, positioning element and overflow properties will do something.

  • Can you explain this odd behavior with dragging items into nested sortables?

    - by RDL
    I have the following setup: A sortable list where one of the <li> has a table with lists in each cell. All of the lists are sortable with each other. Draggable items that can be added to any of the sortables Issue: When adding a draggable item ('drag 1', 'drag 2', 'drag 3') to one of the lists in the horizontal lists (table of lists) it duplicates the draggable when dropped. Sometimes it will create both copies in the same list or one in the item list and one in the column list. Here is a demo: http://jsfiddle.net/MQTgA/ Question: How do I prevent the second item being created when dropping the draggable?
