  • How can I use javascript to convert relative href attributes into absolute paths?

    - by jhensley2
    I have a template that gets screenscraped from an outside vendor and need to include absolute paths in the navigation so the externally hosted content will properly link back to our site. Right now the page/template is driven by a global menu app written by our back end development staff... so anyone who updates our site goes in and changes the menus and their paths... Right now all of the links are linking to relative paths back to the root. For example <a href="/">Home</a> <a href="/news/">News</a> <a href="/media/">Media</a> <a href="/other/">Other</a> I need a simple way (preferably with jquery) to prepend "http://www.domain.com" to each of those links.

  • One-liner javascript to collect values from object graph?

    - by Kevin Pauli
    Given the following object graph: { "children": [ { "child": { "pets": [ { "pet": { "name": "fido" } }, { "pet": { "name": "fluffy" } } ] } }, { "child": { "pets": [ { "pet": { "name": "spike" } } ] } } ] } What would be a nice one-liner (or two) to collect the names of my grandchildren's pets? The result should be ["fido", "fluffy", "spike"] I don't want to write custom methods for this... I'm looking for something like the way jQuery works in selecting dom nodes, where you can just give it a CSS-like path and it collects them up for you. I would expect the expression path to look something like "children child pets pet name"

  • How do you add objects to a javascript namespace?

    - by Fletcher Moore
    var Test = (function() { return { useSub: function () { this.Sub.sayHi(); }, init: function () { $(document).ready(this.useSub); } }; })(); Test.Sub = (function () { return { sayHi: function () { alert('hi'); } }; })(); Test.useSub(); // works Test.init(); // explodes Above I am trying to create a Test namespace and add an object Sub to it. I was doing fine until I tried using the object in jQuery. The error is "Uncaught TypeError: Cannot call method 'sayHi' of undefined". If there is a better way to do this, I am open to it.

  • Why do the following expanded if shorthand statements not work in javascript?

    - by PeanutsMonkey
    This is my first attempt to write shorthand if statements however am befuddled by why the expanded versions don't work quite the way I imagined they would. Code 1 - Does not work if(document.getElementById == true) { alert("The document object model is supported by: " + navigator.appName); } Code 2 - Does work if(document.getElementById != false) { alert("The document object model is supported by: " + navigator.appName); } Code 3 - The shorthand that does work if(document.getElementById) { alert("The document object model is supported by: " + navigator.appName); } Why is that if I expand the shorthand in 3 to the first code sample not work and why does it work if I have it equal to != false?

    - by princyp
    I have a php array that has a bunch of data that I need but specifically I need just the name and longitude and latitude from each item in the array so that I can display points on a google map.

  • How to detect what allowed character in current Regular Expression by using JavaScript?

    - by Soul_Master
    In my web application, I create some framework that use to bind model data to control on page. Each model property has some rule like string length, not null and regular expression. Before submit page, framework validate any binded control with defined rules. So, I want to detect what character that is allowed in each regular expression rule like the following example. "^[0-9]$" allow only digit characters like 1, 2, 3. "^[a-zA-Z_][a-zA-Z_-0-9]+$" allow only a-z, - and _ characters However, this function should not care about grouping, positioning of allowed character. It just tells about possible characters only. By the way, complex regular expression like find two words near(\bword1\W+(?:\w+\W+){1,6}?word2\b) must be ignore to verify and it should return any characters is possible. Do you have any idea for creating this function? PS. I know it easy to create specified function like numeric only for allowing only digit characters. But I need share/reuse same piece of code both data tier(contains all model validator) and UI tier without modify anything. Thanks

  • how to pass in a reference to a string in javascript?

    - by ijjo
    maybe a closure is my solution? not exactly sure how to pull it off though. the code is set up like so: var globalVar = ''; var globalVar2 = ''; function func() { if (condition) func2(globalVar) else func2(globalVar2) } in func2() i cache some HTML in a main container into the appropriate global variable that i pass to it. basically i have a main container that holds different pages depending on what tab they choose. for performance i want to cache the page into global vars so i need to know what tab is active to figure out which global var to assign the html to.

  • Using JavaScript to render HTML; nothing appearing but values will alert

    - by Jack Roscoe
    Hi, I'm taking some information from some variables I have already defined outside this function to create a html svg text box. Here is the function which is causing me trouble: RenderTextBox:function() { alert('this.x: ' + this.x); alert('this.y: ' + this.y); this.textBox = paper.text(this.x, this.y, this.htmlTextBox); } The alerts works prefectly, and prompt me with the values expected. However, the final line which is supposed to create the text box puts them nowhere to be seen. Does anybody know why? If I replace 'this.x, this.y..' with numerical values in the final line of the function, the text box is placed correctly. It's only when I use the 'this.x' and 'this.y' that I have issues.

  • Is there a way to refactor this javascript/jquery?

    - by whyzee
    switch (options.effect) { case 'h-blinds-fadein': $('.child').each(function (i) { $(this).stop().css({opacity:0}).delay(100 * i).animate({ 'opacity': 1 }, { duration: options.speed, complete: (i !== r * c - 1) || function () { $(this).parent().replaceWith(prev); options.cp.bind('click',{effect: options.effect},options.ch); } }); }); break; case 'h-blinds-fadein-reverse': $('.child').each(function (i) { $(this).stop().css({opacity:0}).delay(100 * (r * c - i)).animate({ 'opacity': 1 }, { duration: options.speed, complete: (i !== 0) || function () { $(this).parent().replaceWith(prev); options.cp.bind('click',{effect: options.effect},options.ch); } }); }); break; ....more cases } I have alot of similiar other cases. One way i could think of is to write functions ? i'm not sure i'm still fairly new to the language

  • My javascript doesn't work on IE. What should I change?

    - by klm
    I'm making simple site for my school project. My code doesn't work on my teacher's PC (he has IE 6 or 7 - I don't remember). I use it to change content on site (kind of menu). html: <ul> <li onclick="run(1)"> ... </li> <li onclick="run(2)"> ... </li> <li onclick="run(3)"> ... </li> <li onclick="run(4)"> .... </li> <li onclick="run(5)"> .... </li> <li onclick="run(6)"> .... </li> </ul> Script: function run(x) { ///New Content: var a = ... var e = "<a href='xxxx'> aaaaaa</a>" //example ///////////////////// var p = document.getElementById("content"); if(x === 1) { p.innerHTML=a; } else if(x === 2) { p.innerHTML=b; } else if(x === 3) { p.innerHTML=c; } else if(x === 4) { p.innerHTML=d; } else if(x === 5) { p.innerHTML=e; } else { p.innerHTML=f; } };

  • Best way to set a default button (or trigger its event in javascript) for an input field, not part of a form

    - by Sheldon Pinkman
    I've got a stand-alone input field, not part of any form. I also got a button, that has some onclick event. When I type something in the input field, and press the Enter key, I want it do effectively press the button, or trigger its onclick event. So that the button is "the input field's default button" so to speak. <input id='myText' type='text' /> <button id='myButton' onclick='DoSomething()'>Do it!</button> I guess I can mess around with the input field's onkeypress or onkeydown events and check for the Enter key, etc. But is there a more 'clean' way, I mean something that associated the button with that input field, so that the button is the 'default action' or something for that field? Note that I'm not inside a form, I am not sending, posting, or submitting something. The DoSomething() function just changes some of the HTML content locally, depending on the text input.

  • How to understand "if ( obj.length === +obj.length )" Javascript condition statement?

    - by humanityANDpeace
    I have run across a condition statement which I have some difficulties to understand. It looks like (please note the +-sign on the right-hand-side) this: obj.length === +obj.length. Can this condition and its purpose/syntax be explained? Looking at the statement (without knowing it) provokes the impression that it is a dirty hack of some sort, but I am almost certain that underscore.js is rather a well designed library, so there must be a better explanation. Background I found this statement used in some functions of the underscore.js library (underscore.js annotated source). My guesswork is that this condition statement is somehow related to testing for a variable obj to be of Array type? (but I am totally unsure). I have tried to test this using this code. var myArray = [1,2,3]; testResult1 = myArray.length === +myArray.length; console.log( testResult1 ); //prints true var myObject = { foo : "somestring", bar : 123 }; testResult2 = myObject.length === +myObject.length; console.log( testResult2 ); //prints false

  • How to convert string to XML object in JavaScript?

    - by Jack Roscoe
    Hi, I am aware of this question already existing, but it has given me no luck. I have an application which loads a physicial XML document via the following method: jQuery.ajax( { type: "GET", url: fileName, dataType: "xml", success: function(data) { etc... I parse the XML and convert it into a string which is saved into a variable so that it can easily be stored in a database. How can I now convert the data in this variable back into an XML object so that it can be parsed as such?

  • How to refer to object in JavaScript event handler?

    - by George Edison
    Note: This question uses jQuery but the question has nothing to do with jQuery! Okay so I have this object: var box = new BigBox(); This object has a method named Serialize(): box.AddToPage(); Here is the method AddToPage(): function AddToPage() { $('#some_item').html("<div id='box' onclick='this.OnClick()'></div>"); } The problem above is the this.OnClick() (which obviously does not work). I need the onclick handler to invoke a member of the BigBox class. How can I do this? How can an object refer to itself in an event handler?

  • What are the best JavaScript implementations of a gallery?

    - by gilles27
    We need to implement a gallery feature for our client's new website. They had a similar feature on their last site, which used Smooth Gallery, which in turn was based on Moo Tools. We could go ahead and do the same however, before we do, does anyone have any suggestions for alternatives and if so, please explain why you feel your choice is better.
