• Hiding Text in ie7

  - by user356849

  So I have this text generated by a javascript plugin. <a class="className">Text</a> a.className { background: url(images/a-image.png) no-repeat; } But the "Text" shows on top of the image... Now... with any respectable web browser, I can use color: rgba(0,0,0,0); to solve the problem, but IE7 doesn't obey standards of any sort. Any ideas?

• jQuery UI sortable on select options

  - by user1038814

  I'm trying to get jQuery UI default sortable to work on options in a select multi list box but can't seem to get it working. Can this work with a select option? I've only seen examples with <li> everywhere. Here's my JavaScript: $(function() { $( "#secondSelectms2side__dx" ).sortable(); $( "#secondSelectms2side__dx" ).disableSelection(); }); And the HTML: <select title="" name="secondSelectms2side__dx" id="secondSelectms2side__dx" size="8" multiple="multiple"> <option value="4">asdsdsds</option> <option value="10">bsdsdsdsd</option> <option value="2">csdsdsds</option> </select>? My code is on jsFiddle: http://jsfiddle.net/noscirre/DRUPe/

• jQuery click event not working when mouse moves from one div to another with button held down

  - by Acorn

  I've made a page that uses jQuery to allow you to place <div>s on the page based on your mouse coordinates when you click. The page And here's the javascript: $('document').ready(function() { $("#canvas").click(function(e){ var x = e.pageX - this.offsetLeft; var y = e.pageY - this.offsetTop; $(document.createElement('div')).css({'left':x + 'px', 'top':y + 'px'}).addClass('tile').appendTo('#canvas'); }); }); I've found that if you mousedown in the div#canvas and mouseup with your pointer over a placed <div> (or vice versa) then a new <div> doesn't get placed. Why is this?

• CQRS, Commands, Javascript

  - by Tolu

  I have an architecture where a task-based UI passes commands to a service layer. Now, my intention is to implement the UI in javascript, using KendoUI and the service layer, domain layer etc. in .NET. I'm also looking at future mobile implementations of the client that may use say Java rather than Javascript. If I define the commands in .NET, I'd like to know how to use them from my Javascript client so the client can communicate the commands appropriately to service layer. Do I have to use something like Apache Thrift for this i.e. to define the commands at both the client and service layer?

• How to color HTML elements based on parsing a user command string

  - by Anonymous the Great

  I'm working on a little parsing thing to color objects. For an example, you could type red:Hi!: and "Hi!" would be red. This is my not working code: <script type="text/javascript"> function post() { var preview = document.getElementById("preview"); var submit = document.getElementById("post"); var text = submit.value; <?php str_replace("red:*:",'<i class="red">*</i>',text); ?> preview.value = text; } </script>

• Creating controls in ASP with dynamic IDs

  - by mattdell

  Hi, I'm creating a chat widget that will be dropped into CommunityServer. The widget works great, but I just discovered that if I drop two of these widgets onto the same page, only one of them works! And I'm quite certain the reason is because the chat window is defined in ASP, and now there are two instances of the chat window, with the same ID, on the same page. I am doing this with straight ASP & Javascript (not by choice), so my chat window is defined as: <telerik:RadListBox ID="rlbMessages" runat="server" > (don't mind that it's a telerik control). So I was hoping I could do something like this: <telerik:RadListBox ID="<%= 'rlbMessages' + chatRoomID %>" runat="server" > But from what I've gathered, apparently you can't assign ID's this way? What is the alternative?

• Modular HTML in Adobe AIR? Is It Possible?

  - by Greg Bulmash

  When I write HTML with a PHP backend, I usually have a single header file and a single footer file with some PHP variables in them. The base skeleton for every page calls the header, contains the body content, and then calls the footer. That way, if I want to make changes to the header sitewide, I change one file. I'm working on developing the UI in my first Adobe AIR app and I'm wondering if there's some way to include such files in an HTML based page template there. Obviously, with the file read/write abilities in AIR, I can write a Javascript routine to pull data from a header file, parse it, and inject it into a placeholder. It just seems like such a kludge. I'm thinking there's gotta be some simple way to import a block of HTML into a page without an iFrame or complex post-processor. Something like a PHP include statement or perhaps the old Server Side Includes. Any methods you guys can recommend?

• Hide partial background repeat

  - by ComFreek

  Consider these simple CSS rules: jsFiddle div#container { width: 50%; height: 260px; background-image: url('Image.png'); background-repeat: repeat-x; }? The problem is that I only want full images. If there is not enough space for another duplicate, it should NOT be shown. I've never heard that CSS provides a rule for it. So how can I achieve it in JavaScript (jQuery already included)?

• Open Safari from within Opera Mini on the iPhone

  - by Ican Zilb

  Now that Opera Mini is becoming so popular in the App store I want to effectively warn my web site visitors that the rendition they see in Opera Mini is far from what I meant them to see and redirect them to my page in Mobile Safari, so they can enjoy HTML5 and CSS3. I've been banging my head around that task all day long, but I can't seem to find a solution. My hope lies in the custom URL schemes, but seems Opera Mini handles all schemes which usually Safari does. Would be great if there's a scheme like safari://www.domain.com which opens ONLY in Safari, so I can redirect the visitors to it. Does anybody know a solution to that problem? --edit Just to make myself clear - browser detection is not the problem (I'm doing Javascript for 13 years now) the question is if there's a way to invoke the Safari app on the iPhone from within a web page which is being viewed in Opera Mini.

• Using jQuery for Effects

  - by OneNerd

  Ok - have been tasked with possibly an impossible (or at least a potentially nightmarish) scenario. Need to come as close as possible to reproducing PowerPoint-like effects via HTML/JavaScript (the spec is large and ugly, so I will spare you the details). Ultimately, I am looking for a solid launching point. I have used both Prototype/Scriptaculous as well as jQuery in many projects, and based on what I am seeing, it appears jQuery has the more plug-in available, so am leaning towards using jQuery. Can anyone point me to some plug-ins, articles, or anything else that would help me in accelerating the research on this so I can define to my client what can and cannot be done. Any other suggestions from you jQuery gurus are welcome of course. Thanks -

• Ensuring dynamically added Dojo Dijits are registered in the DOM.

  - by Pro777

  I need to dynamically create Dijits to add N rules to a particular form. Currently I am adding them with the following javascript. var value = new dijit.form.Select({ id: "value_" + counter, store: ValueStore, searchAttr: "description" }, "stateSelect" + counter); value.placeAt(form, "last"); value.startup(); This is creating the element correctly in the form, but it is not associated when the form actually posts. I know Dojo is recognizing the Dijit because the styling is correct. How can I make sure they are included in the DOM form?

  Coud someone help me with this? I am getting these question marks in the graphic and i'm not sure why? I have seen these symbols before and i am sure it had something to do with charset.

• ASP.NET: How to specify which button should defaultly react for an Enter press?

  - by agnieszka

  I have a webpage where there are two buttons and a textbox. When the page loads and user presses enter, the first button is clicked - and that is ok. I would like to assure that if user enters the textBox and types anything there and THEN presses enter, the second button is clicked. When I enter the textBox I can tell that the first button will be used when I press enter, because it is a bit dark-blue-bordered then. I tried javascript's if (event && event.keyCode == 13) document.getElementById("Button2").click(); but it somehow doesn't work. So my second thought was that there must be a possibility to tell the browser which button should defaultly react for an enter press when I'm in a specific textBox (the dark-blue-bordered button). Edit: it might matter that first button is input and the second one is asp:Button

• interfacing: simplified

  - by code wombat

  i've been doing some research on interfaces and a simple layman's explanation for what it truly is. For some reason people love using overly complex explanations and jargon to explain truly simple concepts (guess it makes them feel big) and i have a gut feeling it's the same in this case. so from what i could grasp, it seems like interfaces are nothing more than a way to reserve method names, their return type if any, and the type and amount of arguments they accept. so when a class implements an interface (or interfaces) it is forced to define the body of each method from the interface(s). Am i on the nose with this one or do i need to keep digging? p.s. i know javascript doesn't have support for interfaces, but i still need to understand the concept because there are quite a few places where it's shown how to emulate to an extent.

• Problem with dynamically added script element - attribute src is empty

  - by Stazh

  Hi there, I have a problem with dynamically added script element (using jQuery). Code for adding new script element to DOM is this: var pScript = document.createElement("script"); pScript.type = "text/javascript"; pScript.src = sFile; // Add element to the end of head element $("head").append(pScript); The script is added with no problem, and the code runs perfectly. But, the problem occurs when I try to find the newly added script. I use this code to iterate through all script elements: var bAdd = true; $("script").each(function() { if(this.src == sFile) bAdd = false; }); (I need this code to prevent adding script that is already loaded) Problem is that all other script elements have src attribute set, but the newly added (dynamically) has not... Any idea?

• How do I get the current location of an iframe?

  - by studiothat

  I have built a basic data entry application allowing users to browse external content in iframe and enter data quickly from the same page. One of the data variables is the URL. Ideally I would like to be able to load the iframes current url into a textbox with javascript. I realize now that this is not going to happen due to security issues. Has anyone done anything on the server side? or know of any .Net browser in browser controls. The ultimate goal is to just give the user an easy method of extracting the url of the page they are viewing in the iframe It doesn't necessarily HAVE to be an iframe, a browser in the browser would be ideal. Thanks, Adam

• Does JSLint parse DOM functions?

  - by Paul

  I tried to use the parse() function of JSLint to parse three pieces of JavaScript code: function(b, c){var a = b + c; return a; } window.addEventListener('click', click_hanlder, true); document.documentElement.innerHTML; Here's the code, which is copied and pasted from the JSLint self-parse example: ` try { parse = make_parse(); var source = "something to parse";//replaced by the code above tree = parse(source); if (tree) { document.write(JSON.stringify(tree, ['key', 'name', 'message', 'value', 'arity', 'first', 'second', 'third', 'fourth'], 4)); } } catch (e) { document.write(JSON.stringify(e, ['name', 'message', 'from', 'to', 'key', 'value', 'arity', 'first', 'second', 'third', 'fourth'], 4)); } ` The output: returns a correct tree. returns a tree with only one node of "window". crashes the browser. I'm wondering whether JSLint doesn't support DOM function.

• Easy way to replicate web page across machines?

  - by Mike_G

  I am trying to replicate a browser page to another browser on another machine. I basically want to reproduce a page exactly how it appears to a customer for viewing by the website owner. I have done this before using some impersonation trickery, but found that it would throw the session state out of wack when the site owner would switch customers. So I would like to stay away from cookie and authentication manipulation. Anybody done anything like that? Is there a way to easily transfer the DOM to a webservice? The tech/programming at my disposal are C#, javascript, WCF.

• Calculate open timeslots given availability and existing appointments - by day

  - by Andre

  Overview: I have a table which stores a persons "availability" for a current day, e.g. Mon - 8:00am - 11:30am Mon - 1:30pm - 6:00pm A second table stores appointments that this person already has for the same day, e.g. Mon - 8:30am - 11:00am Mon - 2:30pm - 4pm Desired result: Doing calculationsI'd like to have the following result - e.g. "this person has availability on the given day": Mon - 8:00am - 8:30am Mon - 11:00am - 11:30am Mon - 1:30pm - 2:30pm Mon - 4:00pm - 6:00pm Any ideas on how to calculate the output given the two inputs (e.g. availability, existing appointments) would be greatly appreciated. Preferably I'd use javascript on the client to do the calculating as I would believe that doing it within the DB (I'm using MSSQL) would be slow for many records, persons, etc. Hope this is enough information to illustrate the problem at hand - Many thanks in advance.

• Is is possible to parse a web page from the client side for a large number of words and if so, how?

  - by Technoh

  I have a list of keywords, about 25,000 of them. I would like people who add a certain < script tag on their web page to have these keywords transformed into links. What would be the best way to go and achieve this? I have tried the simple javascript approach (an array with lots of elements and regexping/replacing each) and it obviously slows down the browser. I could always process the content server-side if there was a way, from the client, to send the page's content to a cross-domain server script (I'm partial to PHP but it could be anything) but I don't know of any way to do this. Any other working solution is also welcome.

• What is the most efficient way to get the highest and the lowest values in a Array

  - by meo

  is there something like PHP: max() in javascript? lets say i have an array like this: [2, 3, 23, 2, 2345, 4, 86, 8, 231, 75] and i want to return the highest and the lowest value in this array. What is the fastest way to do that? i have tried: function madmax (arr) { var max = arr[0], min = arr[1] if (min > max) { max = arr[1] min = arr[0] } for (i=1;i<=arr.length;i++){ if( arr[i] > max ) { max = arr[i] }else if( arr[i] < min ) { min = arr[i] } } return max, min } madmax([123, 2, 345, 153, 5, 98, 456, 4323456, 1, 234, 19874, 238, 4]) Is there a simpler way retrieve the max and min value of a array?

• How to count new lines in Internet Explorer?

  - by Impirator

  Hey, all. I'm doing my own syntax highlighter for Javascript and CSS, and I've run into an issue with Internet Explorer (big surprise). I grab all the contents of a code.block tag (example below) using innerHTML, and .split("\n") that result to get each line by itself. This works wonderfully except in IE. I have tried using innerText and .split("\r\n") also without success. Can anyone recommend a solution? If it makes a difference, my code.block tags are styled to be white-space:pre-wrap. <code class="block css">div#randomBarsDemo { width:175px; height:200px; } div#randomBarsDemo div { background-color:#111; width:100%; }</code>
