  • regular expression to insert space beetween thousands and hundreds...

    - by pixelboy
    Regular expressions and I aren't quite good friends. So here's the really basic operation i'm trying to do using javascript (jQuery framwork that is). My calculation function return a number, unformated, and i'd like to separate thousands and hundreds by a white space ' '. I'm sure it's pretty easy for a regexp regular user... but for me... Thanks for the help.

  • Stubhub like map in HTML5?

    - by Switz
    I have an image of a floor plan. Best way to think if it is a hotel floor plan. (Similar to how stubhub does their ticket maps) I want the user to select rooms. Instead of slicing each room in Photoshop, is there a way to split up the image in HTML5 canvas or Javascript. Would like to avoid flash. Thanks for the responses! example: http://adamsaewitz.com/housing/housing.html (top left rooms, hover)

  • possible to auto zoom out if user's resolution < x ?

    - by Haroldo
    my site is aimed purely at the laptop market (dont ask why or argue!), all my users (or 95%+) we on a screen width of 1200+, netbooks are now taking off, with a resolution of 1024 wide. my site still looks great on a netbook if you zoom out once (ctrl-minus), but i don't want to rely on users knowing about ctrl-minus. what are my options besides redesign? I'm keen not to have zoom buttons on my page. is there a javascript zoomer outer?!!!

  • Move options between multiple lists

    - by Martha
    We currently have a form with the standard multi-select functionality of "here are the available options, here are the selected options, here are some buttons to move stuff back and forth." However, the client now wants the ability to not just select certain items, but to also categorize them. For example, given a list of books, they want to not just select the ones they own, but also the ones they've read, the ones they would like to read, and the ones they've heard about. (All examples fictional.) Thankfully, a selected item can only be in one category at a time. I can find many examples of moving items between listboxes, but not a single one for moving items between multiple listboxes. To add to the complication, the form needs to have two sets of list+categories, e.g. a list of movies that need to be categorized in addition to the aforementioned books. EDIT: Having now actually sat down to try to code the non-javascripty bits, I need to revise my question, because I realized that multiple select lists won't really work from the "how do I inform the server about all this lovely new information" standpoint. So the html code is now a pseudo-listbox, i.e. an unordered list (ul) displayed in a box with a scrollbar, and each list item (<li>) has a set of five radio buttons (unselected/own/read/like/heard). My task is still roughly the same: how to take this one list and make it easy to categorize the items, in such a way that the user can tell at a glance what is in what category. (The pseudo-listbox has some of the same disadvantages as a multi-select listbox, namely it's hard to tell what's selected if the list is long enough to scroll.) The dream solution would be a drag-and-drop type thing, but at this point even buttons would be OK. Another modification (a good one) is that the client has revised the lists, so the longest is now "only" 62 items long (instead of the many hundreds they had before). The categories will still mostly contain zero, one, or two selected items, possibly a couple more if the user was overzealous. As far as OS and stuff, the site is in classic asp (quit snickering!), the server-side code is VBScript, and so far we've avoided the various Javascript libraries by the simple expedient of almost never using client-side scripting. This one form for this one client is currently the big exception. Give 'em an inch and they want a mile... Oh, and I have to add: I suck at Javascript, or really at any C-descendant language. Curly braces give me hives. I'd really, really like something I can just copy & paste into my page, maybe tweak some variable names, and never look at it again. A girl can dream, can't she? :) [existing code deleted because it's largely irrelevant.]

  • Why can't I create a Date from a string including milliseconds?

    - by KooiInc
    In javascript you can create a Date object from a string, like var mydate = new Date('2008/05/10 12:08:20'); console.log(mydate); //=> Sat May 10 2008 12:08:20 GMT+0200 Now try this using milliseconds in the string var mydate = new Date('2008/05/10 12:08:20:551'); // or '2008/05/10 12:08:20.551' console.log(mydate); //=> NaN Just out of curiosity: why is this?

  • Temporary Onmouseover

    - by 2x2p1p
    Hi guys :) Css "over" selector applys a temporary style to an element, it isn't definitive: div:hover { background-color: red; } I can use the same thing with javascript but it is a bit complicate and impossible for several elements: var elem = document.getElementByTagName ("div")[0]; elem.onmouseover = function () { this.style.backgroundColor = "red"; } elem.onmouseout = function () { this.style.backgroundColor = "transparent"; } There is a better way ? Something like this: document.getElementByTagName ("div")[0].ontemporarymouseover = function () { // LoL this.style.backgroundColor = "red"; } Thanks

  • What is the relationship between domNode and htmlelement?

    - by Turtle
    Hello, I am confused about the two terms. What is the difference in browser-side javascript programming? I use dojo as framework. And there is only the concept of domNode. But browser debugger always told me something as htmlelement. Are they just the same thing with different names, or with some subtle differences? Thanks.

  • Converting HTML TAG Object to JSON Object

    - by cooldude
    Hi, I want to convert the html tag objects to json object in the javascript in order to send them to the server from the javascript. As i have to save these objects at the Ruby on Rails server. These HTML objects is the canvas tag object and the graphics objects created using CAKE API. I have used the stringify function but it is not working. Here is my code: var CAKECanvas = new Canvas(document.body, 1000,1000); var canvas=CAKECanvas.canvas; var text=document.createElement('textarea'); text.id="text"; text.rows="100"; text.cols="200"; document.body.appendChild(text); canvas.style.borderStyle="solid"; canvas.style.borderColor="black"; var rect= new Circle(); rect.radius=100; rect.centered=true; rect.cx=Math.random() * 500; rect.cy= Math.random() * 300; rect.stroke= false; rect.fill= "red"; rect.xDir = Math.random() > 0.5?1:-1; rect.yDir = Math.random() > 0.5?1:-1; var obj=new Object; var count = 0,k; for (k in rect) { if (rect.hasOwnProperty(k)) { count++; obj[k]=rect[k]; } } alert(count); rect.addFrameListener(function(t, dt) { this.cx += this.xDir * 50 * dt/1000; this.cy += this.yDir * 50 * dt/1000; if (this.cx > 550) { this.xDir = -1; } if (this.cx < 50) { this.xDir = 1; } if (this.cy > 350) { this.yDir = -1; } if (this.cy < 50) { this.yDir = 1; } } ); CAKECanvas.append(rect); var carAsJSON = JSON.stringify(obj); /////////////////ERROR

  • ASP.NET Password textbox, has text as characters entered

    - by SimonNet
    When I look at gmail on my mobile web browser the password textbox hashes the characters as I type so I can see the actual input as I type before is hashed with an asterisk. So as I enter it becomes, P -- *a -- **s etc.. How is this done? I presume its javascript? If somone can point me in the right direction that would be great.

  • Jquery $().each method obscures 'this' keyword

    - by Jeff Fritz
    I am creating a Javascript object that contains a function that executes a jQuery each method like the following: function MyClass { Method1 = function(obj) { // Does something here } Method2 = function() { $(".SomeClass").each(function() { // 1 2 this.Method1(this); }); } } Which object is each THIS referring to? jQuery is referring to the item returned from the each iteration. However, I would like This[1] to refer to the containing class... How can I refer to the containing class from within the jQuery loop?

  • How can I replicate YUI's getElementsBy using Prototype?

    - by LogicWolfe
    I'm moving some code from YUI to javascript and some of it is using YUI's YAHOO.util.Dom.getElementsBy(function). I've been reading through the prototype API docs and haven't been able to find something equivalent. It needs to be able to take an arbitrary function not just select off a CSS selector or the like. Can anyone suggest to me the best way to accomplish this in Prototype?

  • Focus on textbox based on URL.

    - by Cameron
    I have two forms on one page and want to have the input boxes focused based on the URL. So for example: domain.com/Default.aspx#login and domain.com/Default.aspx#register and the javascript I have this: window.document.getElementById('<%=txtUserName.ClientID %>').focus(); window.document.getElementById('<%=txtEmail.ClientID %>').focus(); it might be better if the urls are Default.aspx?action=login actually (not sure if this effects the way in which it would work)

  • Override browser "Find" feature

    - by Trevor Burnham
    I'm wondering whether it's possible to use JavaScript to intercept or prevent the user from using the browser's "Find" feature to find text on the page. (Trust me, I have a good reason!) I'm guessing the answer is "no," beyond the obvious intercepting Cmd/Ctrl+F. A second-best solution would be to intercept the text highlighting that the browser performs during a Find. Is there any way to do this, in any browser?

  • Decode base64 data as array in Python

    - by skerit
    I'm using this handy Javascript function to decode a base64 string and get an array in return. This is the string: base64_decode_array('6gAAAOsAAADsAAAACAEAAAkBAAAKAQAAJgEAACcBAAAoAQAA') This is what's returned: 234,0,0,0,235,0,0,0,236,0,0,0,8,1,0,0,9,1,0,0,10,1,0,0,38,1,0,0,39,1,0,0,40,1,0,0 The problem is I don't really understand the javascript function: var base64chars = 'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/'.split(""); var base64inv = {}; for (var i = 0; i < base64chars.length; i++) { base64inv[base64chars[i]] = i; } function base64_decode_array (s) { // remove/ignore any characters not in the base64 characters list // or the pad character -- particularly newlines s = s.replace(new RegExp('[^'+base64chars.join("")+'=]', 'g'), ""); // replace any incoming padding with a zero pad (the 'A' character is zero) var p = (s.charAt(s.length-1) == '=' ? (s.charAt(s.length-2) == '=' ? 'AA' : 'A') : ""); var r = []; s = s.substr(0, s.length - p.length) + p; // increment over the length of this encrypted string, four characters at a time for (var c = 0; c < s.length; c += 4) { // each of these four characters represents a 6-bit index in the base64 characters list // which, when concatenated, will give the 24-bit number for the original 3 characters var n = (base64inv[s.charAt(c)] << 18) + (base64inv[s.charAt(c+1)] << 12) + (base64inv[s.charAt(c+2)] << 6) + base64inv[s.charAt(c+3)]; // split the 24-bit number into the original three 8-bit (ASCII) characters r.push((n >>> 16) & 255); r.push((n >>> 8) & 255); r.push(n & 255); } // remove any zero pad that was added to make this a multiple of 24 bits return r; } What's the function of those "<<<" and "" characters. Or is there a function like this for Python?
