  • Isolate HTML Div from Javascript/CSS

    - by Neb
    Is there any way to isolate a div from the rest of the page javascript and css? Something like an iframe but without the iframe(because I dont want any extra requests to the server). Here is an example: <html> <head> <style> a{ color:red; } </style> </head> <body> <div> <----- I want the link inside here not to be red <a href="#">test</a> </div> </body> </html>

  • Security / Protecting code in JavaScript

    - by Evans
    With all the recent hype about JavaScript and HTML5 replacing Flash, I wanted to know - How would it be possible to protect client-side js code? Of course, it is possible to obfuscate it, but that would only make it a little harder. Also, for games which submit high scores to the server, wouldn't it be incredibly easy to modify those scores before they are sent to the server? I know even Flash files can be decompiled, but they can be obfuscated and flash decompilation is not as easy as modifying data in JS - could be done easily using a plugin such as Firebug. I'd like to know everyone's views on this.

  • String.Format in javascript?

    - by chobo2
    Hi this is driving me nuts. I believe I asked this exact same question but I can't find it anymore(I used stackoverflow search, google search, manually searched my posts, searched my code). I wanted something that would be like the C# String.Format where you could do something like string format = String.Format("Hi {0}",name); just for javascript of course and one person gave me a simple answer it was not like a jquery plugin or anything but I think you made some json thing or something and it worked and was simple to use. I for the life of me can't find this post.

  • Scrolling a Div programatically using say Javascript

    - by SARAVAN
    Hi I have a jqgrid which is embedded in a Div. I am deleting records from the grid and reloading the grid using grid.Trigger('reload'). The width of the grid is considerably high so it has a scroll bar. Now I scrolled through the end of the grid horizontally before deleting records. Each time I delete the records and reload the grid, the column headers and their values are slightly misaligned. When I move the scroll bar back to original position or just move the scroll bar slightly they are aligned properly. So I thought its better to move the scroll bar to its inital position when the grid reloads. How can a scroll bar be programatically moved using javascript. Or is there any other way to solve my problem?

  • Including javascript files from other projects inside the same solution

    - by gnomixa
    I have a project called WebResources where I have all the JS files that I intend to use in 2 other projects (all three projects sit in the same solution). I just spent 2 hours playing around with the file paths and VS just doesn't see the JS file (unless I specify the full path with the drive letter). Is there a trick to including javascript files relatively from other projects? My file structure is something like: Project1 Default.aspx Project2 WebResourcesProject /js testToInclude.js No matter how I try to include testToInclude.js inside Default.aspx, VS doesn't see it. Any ideas?

  • javascript memory leak

    - by hhj
    I have a some javascript (used with google maps api) that I am testing on IE and Chrome and noticed memory leak symptoms in IE only: when I refresh the page continuously, the amount of memory used in IE keeps growing (fast), but in Chrome it stays constant. Without posting all of the code (as it is rather long), can I get some suggestions as to what to look out for? What could cause the memory to keep growing like this in IE on page refreshes? Like I said I know its hard without code, but I'd like to see if any generic advice works first. Thanks.

  • Is there a Javascript library for editing PDFs?

    - by Fletcher Moore
    Based on my Google and stackoverflow search I'm guessing no, but it can't hurt to ask. The goal is: store some blank forms on my server. Then present these to the user, who edits the form in the browser with Javascript and submits the form back to the server. The client wants to reuse parts of an old system (the forms) in which users would download an editable PDF, edit it, and email it back to a secretary. Our users aren't very computer savvy and many don't realize they need to email the forms back, assuming instead the forms somehow get submitted when they save their local changes (or something). I haven't seen the forms yet, so I cannot assess the viability of an alternative.

  • Javascript Grid that can handle sections in a table

    - by user335410
    I am making an ASP.NET MVC application that lets a user design a questionnaire that other users can fill out. Now, questionnaires, rather than just having a list of questions, often have sections or subsections that could have headings and not the other columns that an ordinary row (a question) would have. I want a JS Grid that can handle sections and subsections elegantly. I tried using JQGrid, but there the options I have are limited to a "Grid as Subgrid" structure. The appearance becomes quite complex and unlike a questionnaire. Is there a Javascript Grid or a JQuery plugin that can handle this? I can write my own HTML table as long as the JS app will format the table and will add some user-friendliness to the table.

  • Basic javascript function

    - by McDan Garrett
    I have this function working <script type="text/javascript"> $(window).scroll(function() { if ($(window).scrollTop() == $(document).height() - $(window).height()) { $('div#loadmoreajaxloader').show(); $.ajax({ url: "loadmore.php?wall=<?php echo $wall; ?>&lastid=" + $(".postitem:last").attr("id"), success: function(html) { if (html) { $("#postswrapper").append(html); $('div#loadmoreajaxloader').hide(); } else { $('div#loadmoreajaxloader').html('<center><font color="white">No more posts to show.</font></center>'); } } }); } }); </script> But I need to have the same stuff happening (on IOS Devices), but instead of it happening when the browser reaches the loadmoreajaxeloader div, I simply need it to happen on an onclick event on a link. Thanks heaps. Tried to add code but didn't format so here it is http://pastebin.com/p2VUqZff

  • Javascript Number Random Scrambler

    - by stjowa
    Hi, I need a Javascript random number scrambler for my website. Seems simple, but I can not figure out how to do it. Can anyone help me out? I have the following array of numbers: 1 2 3 4 5 6 7 8 9 I would like to be able to have these numbers scrambled randomly. Like the following: 3 6 4 2 9 5 1 8 7 or 4 1 7 3 5 9 2 6 8 So, specifically, I would like a function that takes in an array of numbers (1 - n) and then returns that same array of numbers - scrambled randomly with different calls to the function. Maybe a noob function, but can't seem to figure it out. Thanks!

  • JavaScript-library-based Project Organization

    - by Laith J
    Hello, I'm very new to the JavaScript library world. I have used JS by itself before to create a mini social network but this is the first time I use a JS library and I really don't know how to go about this. I'm planning to use Google Closure and I'm really not sure how I should go about organizing the code. Should I put everything in one file since it's a web app and should have one screen? Should I separate the code to many chunks and put them in different files? Or should I put different dialogs (like settings) in a separate page and thus a separate file? Like all programmers I'm a perfectionist so please help me out with this one, thanks.

  • JavaScript Namespace Declaration

    - by Hery
    I created a javascript class as follow: var MyClass = (function() { function myprivate(param) { console.log(param); } return { MyPublic : function(param) { myprivate(param); } }; })(); MyClass.MyPublic("hello"); The code above is working, but my question is, how if I want to introduce namespace to that class. Basically I want to be able to call the class like this: Namespace.MyClass.MyPublic("Hello World"); If I added Namespace.MyClass, it'll throw error "Syntax Error". I did try to add "window.Namespace = {}" and it doesn't work either. Thanks.. :)

  • Javascript: selfmade methods not working correctly

    - by hdr
    Hi everyone, I tried to figure this out for some days now, I tried to use my own object to sort of replace the global object to reduce problems with other scripts (userscripts, chrome extensions... that kind of stuff). However I can't get things to work for some reason. I tried some debugging with JSLint, the developer tools included in Google Chrome, Firebug and the integrated schript debugger in IE8 but there is no error that explains why it doesn't work at all in any browser I tried. I tried IE 8, Google Chrome 10.0.612.3 dev, Firefox 3.6.13, Safari 5.0.3 and Opera 11. So... here is the code: HTML: <!DOCTYPE HTML> <html manifest="c.manifest"> <head> <meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1"> <meta charset="utf-8"> <!--[if IE]> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/chrome-frame/1/CFInstall.min.js"></script> <script src="https://ie7-js.googlecode.com/svn/version/2.1(beta4)/IE9.js">IE7_PNG_SUFFIX=".png";</script> <![endif]--> <!--[if lt IE 9]> <script src="js/lib/excanvas.js"></script> <script src="https://html5shiv.googlecode.com/svn/trunk/html5.js"></script> <![endif]--> <script src="js/data.js"></script> </head> <body> <div id="controls"> <button onclick="MYOBJECTis.next()">Next</button> </div> <div id="textfield"></div> <canvas id="game"></canvas> </body> </html> Javascript: var that = window, it = document, k = Math.floor; var MYOBJECTis = { aresizer: function(){ // This method looks like it doesn't work. // It should automatically resize all the div elements and the body. // JSLint: no error (execpt for "'window' is not defined." which is normal since // JSLint does nor recognize references to the global object like "window" or "self" // even if you assume a browser) // Firebug: no error // Chrome dev tools: no error // IE8: that.documentElement.clientWidth is null or not an object "use strict"; var a = that.innerWidth || that.documentElement.clientWidth, d = that.innerHeight || that.documentElement.clientHeight; (function() { for(var b = 0, c = it.getElementsByTagName("div");b < c.length;b++) { c.style.width = k(c.offsetWidth) / 100 * k(a); c.style.height = k(c.offsetHight) / 100 * k(d); } }()); (function() { var b = it.getElementsByTagName("body"); b.width = a; b.height = d; }()); }, next: function(){ // This method looks like it doesn't work. // It should change the text inside a div element // JSLint: no error (execpt for "'window' is not defined.") // Firebug: no error // Chrome dev tools: no error // IE8: no error (execpt for being painfully slow) "use strict"; var b = it.getElementById("textfield"), a = [], c; switch(c !== typeof Number){ case true: a[1] = ["HI"]; c = 0; break; case false: return Error; default: b.innerHtml = a[c]; c+=1; } } }; // auto events (function(){ "use strict"; that.onresize = MYOBJECTis.aresizer(); }()); If anyone can help me out with this I would very much appreciate it. EDIT: To answer the question what's not working I can just say that no method I showed here is working at all and I don't know the cause of the problem. I also tried to clean up some of the code that has most likely nothing to do with it. Additional information is in the comments inside the code.

  • Great guide for JavaScript GZIP compression in IIS?

    - by Django Reinhardt
    Hi there, we're looking to compress our gargantuan JavaScript files with GZip to speed up the page loads of our site. I know this can be done through IIS, but I can't seem to find a simple step-by-step guide on how to implement it. If someone could point me towards such a guide, I'd really appreciate it. I've never done this before, so it would need to be quite basic. We're running IIS7.5 on Windows Server 2008 R2. Your time is much appreciated.

  • Parallel Processing Simulation in Javascript

    - by le_havre
    Hello, I'm new to JavaScript so forgive me for being a n00b. When there's intensive calculation required, it more than likely involves loops that are recursive or otherwise. Sometimes this may mean having am recursive loop that runs four functions and maybe each of those functions walks the entire DOM tree, read positions and do some math for collision detection or whatever. While the first function is walking the DOM tree, the next one will have to wait its for the first one to finish, and so forth. Instead of doing this, why not launch those loops-within-loops separately, outside the programs, and act on their calculations in another loop that runs slower because it isn't doing those calculations itself? Retarded or clever? Thanks in advance!

  • InfoPath browser form submitting dirty fields changed through javascript

    - by Xavier
    I'm trying to submit an InfoPath browser form with fields that have been modified through the Spell Checker included in Sharepoint server. The spell checker checks all the fields in the page and once the user closes the SpellChecker dialog, it changes the textboxes with the new values through javascript. When I click Submit, debug the FormEvents_Submit in the form code behind and try to do a GetNodeValue("XPath to changed field"), it still shows the old values. I realize that this may be a problem of doing postbacks and I'd like to do a full page postback once the SpellChecker is done changing all the textboxes. Any suggestions would be appreciated. Thanks.

  • Javascript Prototyping Question

    I'm just reading about Prototypes in JavaScript and Douglas Crockford offers and excellent way to select a new objects prototype but can anyone explain (below) why obj01's type equals 'object' when I pass it in function as it's prototype? if (typeof Object.beget !== 'function') { Object.beget = function (o) { console.log(typeof o);//function var F = function () {}; F.prototype = o; console.log(typeof F);//function return new F(); }; } var func01 = function(){}; var obj01 = Object.beget(func01); console.log(typeof obj01);//object console.log(typeof obj01.prototype);//object I thought it would be console.log(typeof obj01);//function console.log(typeof obj01.prototype);//function

  • Are closures in javascript recompiled

    - by Discodancer
    Let's say we have this code (forget about prototypes for a moment): function A(){ var foo = 1; this.method = function(){ return foo; } } var a = new A(); is the inner function recompiled each time the function A is run? Or is it better (and why) to do it like this: function method = function(){ return this.foo; } function A(){ this.foo = 1; this.method = method; } var a = new A(); Or are the javascript engines smart enough not to create a new 'method' function every time? Specifically Google's v8 and node.js. Also, any general recommendations on when to use which technique are welcome. In my specific example, it really suits me to use the first example, but I know thath the outer function will be instantiated many times.

  • Automated browsing with javascript?

    - by Paul Wicks
    I'm trying to do some browser automation, but I'm having some problems. Basically, what I'd like to do is load a set pages, set some forms options, click a button and view the results for each page that I open. Originally, I tried to do this by placing the pages I wanted to automate in iframes and then using javascript to drive the interactions I want in each, but that results in a Permissions Error, since the sites I want to automate are not on my server. Is there any way around this? The other possibility I've thought of is to use QT's webkit class and the evaluateJavaScript method to accomplish what I'd like to do, but this seems a bit more heavy weight for something that is, conceptually, pretty simple.
