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.
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.
I would like to return the style left value from an element. Is this possible with javascript?
<script type="text/javascript"> function moveleft() a test function { document.getElementById("first").style.left = "50px"; if I try alert(document.getElementById("first").style.left);
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?
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:
I'm using the jquery topZIndex plugin in my application. It's working great. Now I have a situation though, where I would like to return the element with the highest z-index on the page. The plugin has a function that will return the highest z-index, but it's a value, not an object.
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
In this case the e.srcElement/e.target should return 'home' or 'about', but instead one of the two layers inside 'home' or 'about' will be returned. And these dont even have a onmouseover attribute! The following page is specially made to make it easy to fix the bug if you know how :-)[URL]
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:
i have 2 radios :what i need is once i choose the 1st radio i will get 1st DDL with folollwing element :Orange AppleKiwiif i chose the 2nd radio i should have the 2nd DDL with :PotatoTomatolegume
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 = $(this).width();
I am trying to select a div element based on its display property. Due to some reasons I can't use Id to select this element, DIV element is structured like this:
Is there a way to call javascript functions based on the text between a span element? In other words if I have <span id="mySpan">Bronze</span> then it will call a javascript function but if I have <span id="mySpan">Silver</span> then it will call a different function?
Is there any way to enable a form element(s) based on the selection in a <select> drop-down? I'm trying to enable/disable a group of checkboxes depending on which option is chosen in the <select> above it.I know how to enable/disable something when a box is checked (or text is entered into it) but I have no clue how to handle the <select> option.
with jquery, i try to get the margin-left ($('#mydiv').css('margin-left'), but the function return 0px, unable to retrieve the good value (auto) anyone has idea to retrieve the value "auto" when margin-left is "auto" ?
how to do it If I have something like this: var d = {one:1, two:2, three:3}; and I want to add a new item to d, how can I do it? I have looked up the documentation and found the function called data (name, value) and I tried doing this $(d).data("four",4); but it wasn't added
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?
