Var Object - Return A Var Element From Key Based?

Aug 20, 2010

i've seen this code at work which i do not get.

var Key = {
'Number1': 49, 'Number2': 50, 'Number3': 51, 'Number4': 52, 'Number5': 53, 'Number6': 54, 'Number7': 55,
'Number8': 56, 'Number9': 57, 'Number0': 48,
};

I need to return a var element from Key based what a var containing a string contains e.g

var string = "1"; an example

return Key.Number1

How would I do this using a for loop and not having multiple if statements

JQuery :: Star Rating: Set Value And Disable Based On Ajax Return Value?

Sep 22, 2011

I'm implementing theStar Ratingplugin. Star rating is called like this:

$(function(){
$('.stars').rating({
callback: function(value, link){
$.ajax({

[Code]....

After a star is clicked the form is submitted and processed. "rate.php" returns an integer from 1 to 5 with the new average rating. So far so good, but I'd like to update the Star radios with the new value and disable them after the form has been processed.

It seemed easy enough:

$('.stars').rating('select', data);
$('.stars').rating('disable');

Return An Object From A String

May 19, 2006

reSplit is used to return an object from a string of name/value pairs.

pass reSplit()your own delimeters or use the defaults.

String.prototype.reSplit= function(d1,d2){
if(!d1) d1= /s*;s*/
if(!d2) d2= /s*=/;
var Obj= new Object, tem;
var A= this.split(d1);
var L= A.length;
for(var i= 0; i< L; i++){
if(!A[i]) continue;
tem= A[i].splat(d2);
Obj[tem[0]]=tem[1];
}
return Obj;
};
String.prototype.splat= function(delim){
var ax,L;
var d= this.match(delim);
if(!d) return this;
else{
ax= d.index;
L= d[0].length;
return [this.substring(0,ax), this.substring(ax+L), d[0]];
}
};

Return An Object To A Div Area?

May 7, 2009

I have three buttons set up using onClick. These buttons are used to display the differing results from an object. They work except the results are displayed on a new page. Ive been trying to get them to display the results in the same page using a div. The problem is I cant get them to work properly i.e the result wont display at all in the div area.

Here is my code

Code:

<body>
<input type="button" value="emp1" onClick="document.write(ger.getFullName())">
<input type="submit" value="emp2" onClick="document.write(tom.getFullName())">
<input type="submit" value="emp3" onClick="document.write(mar.getFullName())">

[code]....

How do i get the results to display in the div?

JQuery :: LoadImage - Function Not Return Valid Object

Jan 10, 2011

I'm writing a function that substantially load a given image making a fadeout/faidin waiting 'till the complete load. The function is named "loadImage" and I would like use it in the following way:
$('#image img').fadeOut().loadImage(src).attr("src",src).fadeIn();

In order to make the image disappear, load... change the attribute "src" of the image and then re-appear. The code for the function is:
(function($) {
$.fn.loadImage = function(src) {
var img = new Image();
$(img).attr('src', src).load(function() {
return this;
});
}})(jQuery);

But when I run it I get the following error:
$("#image img").fadeOut().loadImage(src) is undefined
I think that the function don't return a "valid" object to make it chainable, isn't it?

Return Keyword Applied On Object Returns Reference Or Value?

Aug 24, 2010

I am confused about what the return keyword is actually returning when returning an object, a primitive, or a function. My confusion is compounded by the fact that I'm not sure if a function is an object or not. According to the book JavaScript Programmer Reference it is: "All functions in JavaScript are first class objects , meaning they can be passed around like any other object reference. In fact, regardless of how they are created, functions are instances of a global object named (aptly) Function."

However, someone else states that a function is not an object. An object is a set of primitives and references. A function is executable code. Functions become objects through the use of the new operator. Yet, in the book I mentioned, it says you don't need the new keyword to execute the function as an object, as it already inherits from the object Function when the function keyword is used:

function functionName([argname1 [, ...[, argnameN]]])
{
statements;
}

So there's one source of contradiction. Now the bigger issue is what is going on when the return keyword is used. Notice the Validation() function returns an object as its last expression. This technique is common, where you return an object which contains functions in form of object notation. I believe this is done so that we create a closure so that when the intepreter exits the Validation() method, since we created a closure by returning an object, which contains the inner functions addRule and getRule, the local variables of Validation() are not destroyed, given that we can reference them through the two inner functions that make use of the local variables of the outer function. So when we use the return keyword on an object literal, and then exit the function, when we call one of the inner functions as we do later:

JQuery :: Losing Object Definition On Return To A Click Handler?

Feb 8, 2011

I am looping through an array of objects and creating an <li> element for each one and appending to a <ul> in the DOM. Works fine.During the looping I am also attached a 'details' object as data for the list element:$(thisListItem).data('details',{<obj>});Later, I am using the selector:$('ul#images_list li')to attach an on click function for each <li> element.In the click handler I am reading the data 'details' object for the <li> element:dataDetails = $.data(lotImage,'details');and, using the jAlerts plugin, I am opening a jPrompt which asks for the user to enter a price.

The jPrompt call includes a callback which receives the entered value as a parameter. The callback uses the value to 'post' the updated value, via $.ajax, to a server side unction.After OK is clicked in the jPrompt popup, in Firebug, I get an error that the dataDetails is undefined and it lists the line number in the click handler where I originally read the data object from the <li> element.I don't really understand why it should care after the click event has fired and the jPrompt callback has been invoked

Misunderstanding - Replace Prototyping With Own Array Type Based On Object

Dec 17, 2009

I'm apparently misunderstanding what I'm reading on prototyping. My main task is to squeeze some performance out of an app that's a bit slow on IE, and it looks like large Arrays and their overhead may be part of the problem. I'm trying to replace those with my own array type based on Object and extend it with helper functions like .length. Here's a munged sample of what I've tried:

JQuery :: Dynamic CSS Padding Based On Element Width?

Oct 21, 2010

I'm currently working on an IE7 CSS fix for a rather large form. Long story short, I have each input wrapped in a div, all in the same class. What I need, is to have each div define a padding-right value that is equal to the width of that div. I'm fairly new to jQuery, so I'm in need of some help with the syntax. Here's what I currently have, but it keeps printing a padding-right value of "0".

$('.form_label').each(function(){
$(this).css('padding-right', function() {
var w = $(this).width();

Onclick Event For OBJECT Element In IE

May 3, 2006

I can't set onclick event properly for OBJECT (flash) element properly. onclick just don't bubble outside flash object. Could this be caused by AS getUrl() function?

I tried to attach thru .htc, tried transparent IFRAME on top of object, etc. Nothing seems to work.

Is there any reasonable way to attach onclick to OBJECT element or flash movie by using JS or plain HTML? Should I do something for event bubbling?
