• Run function in infinite loop

• UI suggestions on how to display suggested tags for a given text to a user?

  - by Danny

  I am writing a web-app that uses a tagging system to organize the user's submitted reports. Part of it uses ajax to get suggestions for tags to present to the user based on the content of their report. I am looking for suggestions on how to present this information for the user. I'm not quite certain what a friendly way to do this would be. Edit: Well, most of the responses here seem to be focused on the user typing in keywords. The idea I'm trying to define here is more towards presenting the user a set of suggested keywords that they may accept or decline without having to type a tag in manually. (That option is of course still available to them) --------------------------- # say they can checkoff or select tags they like. | o[tag2] x[foo] o[moo] | | x[tag1] o[bar] | ---------------------------

• jquery thickbox height problem

  - by Swami

  My thickbox renders correctly in my dev environment, but in prod, the default height kicks in even though I'm supplying width and height params. TB_WIDTH = (params['width']*1) + 30 || 630; //defaults to 630 if no paramaters were added to URL TB_HEIGHT = (params['height']*1) + 40 || 440; //defaults to 440 if no paramaters were added to URL ajaxContentW = TB_WIDTH - 30; ajaxContentH = TB_HEIGHT - 45; Any thoughts on why this might be happening?

• Array.sort Sorting Stability in Different Browsers

  - by Boushley

  What is the stability of Array.sort in different browsers. I know that the ECMA Script specification does not specify which algorithm to use, nor does it specify whether the sort should be stable. I've found this information on for Firefox https://developer.mozilla.org/en/Core_JavaScript_1.5_Reference/Global_Objects/Array/sort which specifies that firefox uses a stable sort. Does anyone know about IE 6/7/8, Chrome, Safari?

• convert list of relative widths to pixel widths

  - by mkoryak

  This is a code review question more then anything. I have the following problem: Given a list of relative widths (no unit whatsoever, just all relative to each other), generate a list of pixel widths so that these pixel widths have the same proportions as the original list. input: list of proportions, total pixel width. output: list of pixel widths, where each width is an int, and the sum of these equals the total width. Code: var sizes = "1,2,3,5,7,10".split(","); //initial proportions var totalWidth = 1024; // total pixel width var sizesTotal = 0; for (var i = 0; i < sizes.length; i++) { sizesTotal += parseInt(sizes[i], 10); } if(sizesTotal != 100){ var totalLeft = 100;; for (var i = 0; i < sizes.length; i++) { sizes[i] = Math.floor(parseInt(sizes[i], 10) / sizesTotal * 100); totalLeft -= sizes[i]; } sizes[sizes.lengh - 1] = totalLeft; } totalLeft = totalWidth; for (var i = 0; i < sizes.length; i++) { widths[i] = Math.floor(totalWidth / 100 * sizes[i]) totalLeft -= widths[i]; } widths[sizes.lenght - 1] = totalLeft; //return widths which contains a list of INT pixel sizes

• Dynamically changing background color of specific text without changing other attributes

  - by gsingh2011

  I've written a chrome extension to find text on a page based on a regex query. When text is matched, I wrap the matched text in a <span> tag that has the class highlight where highlight only changes the background color to yellow. The issue is that sometimes there are already styles applied to <span> tags in a webpage. For example, the webpage might have this defined: span { font-size: 200%; } So when I insert my <span> tag in another <span> tag, the font-size is actually 400%. Is there an easy way for my code to just change certain properties of the text, like the background color, without applying the webpage's styles twice?

• Get Json and output to text file undecoded

  - by Gary

  Hi, I want to fetch json script and write it to a txt file undecoded, exactly how it was originally. I do have a script that I use that I am modifying but unsure what to commands to use. This script decodes, which is what I want to advoid. //Get Age list($bstat,$bage,$bdata) = explode("\t",check_file('./advise/roadsnow.txt',60*2+15)); //Test Age if ( $bage > $CacheMaxAge ) { //echo "The if statement evaluated to true so get new file and reset $bage"; $bage="0"; $file = file_get_contents('http://somesite.jsontxt'); $out = (json_decode($file)); $report = wordwrap($out->mainText, 100, "\n"); //$valid = $out->validTo; //write the data to a text file called roadsnow.txt $myFile = "./advise/roadsnow.txt"; $fh = fopen($myFile, 'w') or die("can't open file"); $stringData = $report; fwrite($fh, $stringData); } else { //echo the test evaluated to false; file is not stale so read local cache //print "we are at the read local cache"; $stringData = file_get_contents("./advise/roadsnow.txt"); } // if/else is done carry on with processing //Format file $data = $stringData

• How to use jQuery to assign a class to only one radio button in a group when user clicks on it?

  - by xraminx

  I have the following markup. I would like to add class_A to <p class="subitem-text"> (that holds the radio button and the label) when user clicks on the <input> or <label>. If user clicks some other radio-button/label in the same group, I would like to add class_A to this radio-button's parent paragraph and remove class_A from any other paragraph that hold radio-buttons/labels in that group. Effectively, in each <li>, only one <p class="subitem-text"> should have class_A added to it. Is there a jQuery plug-in that does this? Or is there a simple trick that can do this? <ul> <li> <div class="myitem-wrapper" id="10"> <div class="myitem clearfix"> <span class="number">1</span> <div class="item-text">Some text here </div> </div> <p class="subitem-text"> <input type="radio" name="10" value="15" id="99"> <label for="99">First subitem </label> </p> <p class="subitem-text"> <input type="radio" name="10" value="77" id="21"> <label for="21">Second subitem</label> </p> </div> </li> <li> <div class="myitem-wrapper" id="11"> <div class="myitem clearfix"> <span class="number">2</span> <div class="item-text">Some other text here ... </div> </div> <p class="subitem-text"> <input type="radio" name="11" value="32" id="201"> <label for="201">First subitem ... </label> </p> <p class="subitem-text"> <input type="radio" name="11" value="68" id="205"> <label for="205">Second subitem ...</label> </p> <p class="subitem-text"> <input type="radio" name="11" value="160" id="206"> <label for="206">Third subitem ...</label> </p> </div> </li>

• Capturing the contents of <select>

  - by joey mueller

  I'm trying to use a regular expression to capture the contents of all option values inside an HTML select element For example, in: <select name="test"> <option value="blah">one</option> <option value="mehh">two</option> <option value="rawr">three</option> </select> I'd like to capture one two and three into an array. My current code is var pages = responseDetails.responseText.match(/<select name="page" .+?>(?:\s*<option .+?>([^<]+)<\/option>)+\s*<\/select>/); for (var c = 0; c<pages.length; c++) { alert(pages[c]); } But it only captures the last value, in this case, "three". How can I modify this to capture all of them? Thanks!

• Prototype mouseleave for two connected elements

  - by TenJack

  I have created a small navigation element that is positioned right on top of another element. It is only shown when a user mousenters/mouseovers the main element. I am having some trouble with the prototype. I would like this small nav element to be hidden when a user mouses out of the main box, but I would also like the small nav element to remain visible if a user mouses out of the main box but mouses into the small nav at the same time. This is my attempt so far with some pseudo-code to hopefully explain: $('main_box').observe('mouseenter', function(){ $('small_div').show() }) $('main_box').observe('mouseleave', function(){ if this element is $('small_div') then Event.stop() $('small_div').observe('mouseleave', function(){ if this element is $('main_box') Event.stop observe $('main_box') mouseleave else $('small_div').hide(); }) else $('small_div').hide(); }) The main thing I'm having trouble with is figuring out what element the mouse is over at a given point in time. Is there a way to do something like: on mouseleave do blah unless the mouse is over a specific element then do not do blah?

• What is the proper way to credit public code snippets?

  - by Babiker

  This question might not be a programming problem, but its been bothering me. There is a lot of free js/css scripts out there for public use. I some times use these scripts. If any, what is the formal and proper way to credit these snippets when all i have is a name of a website and a url. I understand that a simple comment might get the job done but i wanted to know whether there is a more professional way.

• Changing document.domain to completely other domain

  - by Sergej Andrejev

  I'm trying to prove that changing document.domain can be used only for cross scripting on the same upper level domain. For example if i will try to change document.domain to "google.com" on page which is located on www.test.com I will get a security exception in FF. Does anybody know where to locate an official proof of that?

• Why does an onclick property set with setAttribute fail to work in IE?

  - by Aeon

  Ran into this problem today, posting in case someone else has the same issue. var execBtn = document.createElement('input'); execBtn.setAttribute("type", "button"); execBtn.setAttribute("id", "execBtn"); execBtn.setAttribute("value", "Execute"); execBtn.setAttribute("onclick", "runCommand();"); Turns out to get IE to run an onclick on a dynamically generated element, we can't use setAttribute. Instead, we need to set the onclick property on the object with an anonymous function wrapping the code we want to run. execBtn.onclick = function() { runCommand() }; BAD IDEAS: You can do execBtn.setAttribute("onclick", function() { runCommand() }); but it will break in IE in non-standards mode according to @scunliffe. You can't do this at all execBtn.setAttribute("onclick", runCommand() ); because it executes immediately, and sets the result of runCommand() to be the onClick attribute value, nor can you do execBtn.setAttribute("onclick", runCommand);

• Custom Alignment and Backgrounds Through Greasemonkey

  - by Jivec

  I'm trying to implement something in greasemonkey and it is giving me a fair bit of trouble as I can't get it to work. I frequently use Wolfram Alpha (http://wolframalpha.com) for a lot of things. They have recently updated the home page with a new style. There are settings that you can edit on this page (http://www.wolframalpha.com/homesettings.html) As you would expect when you clear cookies you loose these settings. What I would like to do is have a greasemonky script that sets the background to what ever I like (which will stay also regardless of the state of your cookies). It would also be cool if this background was displayed the whole way through Wolfram Alpha (ie when you make queries too eg. http://www.wolframalpha.com/input/?i=stack+overflow ) The other thing I'm trying to implement but I'm struggling is to force the results pages to be left aligned so that the browser window can be smaller. If anyone could help me with this it would be appreciated, I have tried to do it my self but I'm unsure how to get it to work.

• How to select this with JSON...

  - by Oscar Godson

  I actually have two questions, both are probably simple, but for some odd reason I cant figure it out... I've worked with JSON 100s of times before too! but here is the JSON in question: {"69256":{"streaminfo":{"stream_ID":"1025","sourceowner_ID":"2","sourceowner_avatar":"http:\/\/content.nozzlmedia.com\/images\/sourceowner_avatar2.jpg","sourceownertype_ID":"1","stream_name":"Twitter","streamtype":"Social media","appsarray":[]},"item":{"headline":"Charboy","main_image":"http:\/\/content.nozzlmedia.com\/images\/author_avatar173212.jpg","summary":"ate a tomato and avocado for dinner...","nozzl_captured":"2010-05-12 23:02:12","geoarray":[{"state":"OR","county":"Multnomah","city":"Portland","neighborhood":"Downtown","zip":"97205","street":"462 SW 11th Ave","latitude":"45.5219","longitude":"-122.682"}],"full_content":"ate a tomato and avocado for dinner tonight. such tasty foods. just enjoyable.","body_text":"ate a tomato and avocado for dinner tonight. such tasty foods. just enjoyable.","author_name":"Charboy","author_avatar":"http:\/\/content.nozzlmedia.com\/images\/author_avatar173212.jpg","fulltext_url":"http:\/\/twitter.com\/charboy\/statuses\/13889868936","leftovers":{"twitter_id":"tag:search.twitter.com,2005:13889868936","date":"2010-05-13T02:59:59Z","location":"iPhone: 45.521866,-122.682262"},"wordarray":{"0":"ate","1":"tomato","2":"avocado","3":"dinner","4":"tonight","5":"tasty","6":"foods","7":"just","8":"enjoyable","9":"Charboy","11":"Twitter","13":"state:OR","14":"county:Multnomah, OR","15":"city:Portland, OR","16":"neighborhood:Downtown","17":"zip:97205"}}}} Question 1: How do I loop through each item (69256) when the number is random? e.g. item 1 is 123, item2 is 646? Like, for example, a normal JSON feed would have something like: {'item':{'blah':'lorem'},'item':{'blah':'ipsum'}} the JS would be like console.log(item.blah) to return lorem then ipsum in a loop How do I do it when i dont know the first item of the object? Question 2: How do I select items from the geoarray object? I tried: json.test.item.geoarray.latitude and json.test.item.geoarray['latitude']
