Here's an example of the returned json which I'm trying to parse back into a js object:
{"name":"John"}
After setting that string to a js variable called modelJson, here's my code trying to convert it:
var dictModelList = $.parseJSON(modelJson);
then I test to see if it's null or not and it definitely shows null when this alert pops:
alert("dictYearList: " + dictModelList);
i'm trying to get a JSON-request from this API: h

I am returning the following to $getJSON() and not getting any results:
{"QC":["x","y","z"],"RM":[{"DEFAULT":"default_project1"},{"DEFAULT2":"default_project2"},{"DEFAULT":"default_project3"}]}
In the "RM" array there are three objects, each a single name/value pair. The name of the array[0] object ("DEFAULT") is identical to the name of the array[2] object. No results are returned by the getJSON call. Since each object is a separate array value, there shouldn't be any object name collision problems. Note that if I change the name of the array[2] object to "DEFAULT3", the data structure is handled properly.
So, I read about the new method of passing an object map containing element properties when creating a new jQuery object (as discussed at the bottom of this article). The article says that it supports ALL events, but only gives examples of simple events that require no parameters. I'm trying to implement a live event using the following and can't get it to work:
var link = $('<a />', {
text: config.appendTextMore,
href: "#",
[code]....
$(document).ready(function() {
The SELECTor shows up in the document but it's not MULTIPLE, no ALT text, no CLICK event handler.
I have a Flash movie on a web page and I want to send parameters to it with JavaScript to have it go to a selected frame. The AS3 code receives its information via an ExternalInterface API. The following code parses the URL argument (?page=x) and I want to send the value (x) to Flash. Unfortunately, when creating the objMovie variable, it is always undefined, therefore getFlashMovie is undefined and Flash never receives the callback. Thinking that it was because the flash movie is not loaded yet, I created a button to call callToActionscript, and when I click the button, I get the same error.
(getFlashMovie("myFlashMovie") is undefined)
Also,
if (params)
always returns true, whether there are parameters or not. I don't understand that, either.
The code follows:
<script >
$(document).ready(function() {
var params=getQueryParameters();
if(params) {
callToActionscript(params[0]);
}});
function getFlashMovie(movieName) {
var isIE = navigator.appName.indexOf("Microsoft") != -1;
var objMovie = (isIE) ? window[movieName] : document[movieName];
alert(objMovie); //Always return undefined
return objMovie;
} function callToActionscript(page) {
var myMovie=getFlashMovie("myFlashMovie").sentToActionscript(page);
} function getQueryParameters() {
var query = window.location.href.split('?')[1];
//query won't be set if ? isn't in the URL
if(!query) {
return { };
} else{
var param = query.split('=');
} return param[1];
}
</script>
I am doing javascript from a book called "Prentice Hall(which sounds very masonic) : Javascript by example".
my question is this. I am doing an practice dealing with "defining methods for an object" now i used this code verbatim
[Code]...
I did this code in the book exactly. I am just trying to warp my head around this and want to understand how is this an error when it is just the crating a new property.
I am creating a game in JavaScript!
It is going to be a clone of the game ChuChu Rocket! that I used to play on the Dreamcast.
The game is set up so that the levels sit inside a nested array of objects, like your typical JSON string. So that within levels[] there are objects with level names, an array of moveable items, an array of arrows you can place, etc.
I have set it up so that when the level is loaded in to the DOM, it also duplicates a part of the object, the part responsible for the positioning of the moveable items on screen so that when they are animated, and if there is a fail scenario (cat eats mouse, cat gets to rocket before mouse) you should be able to reset and it remembers your coordinates.
From what I have learned in my years of studying and using JavaScript, the following should always hold true: a=1; b=a; b++; // b would become 2, a would stay as 1 (they are separate variables)
I seem to have found an exception to this rule.
When creating a level, I duplicate the part of my object called o.chuchu and I call it o.chuchuMoving
If I make a change to anything in o.chuchuMoving, it also changes o.chuchu.
o.chuchu and o.chuchuMoving are arrays within the object. Formatted like this: [0,0,1],[1,0,1],[2,0,1],[3,0,1] ... etc
If I tell my object the following: o.chuchuMoving[0][0]=1... then o.chuchu[0][0] also becomes 1.

I am creating a job ticket object that will interact with a database. It has to update the database on the fly via AJAX. Within the job ticket object, I have instances of a Component Object. Within the Component Object, I have an instance of an Editor Object. One of the methods of the Editor object is a function to edit some text and when it's submitted, it will update the database. All of that is working fine. My problem is that I need to refresh the screen with the new contents of the database. I have a method in the Component Object that refreshes the screen, but how do I call it from within the Editor Object? I believe it has to be called there because the editor object has a handler for the form submission and the AJAX function. So I'll have to reference a callback function once the AJAX request is handled, but I don't know how to call it.
I know that sounds kind of convoluted, so hopefully, this very simplified code will paint a better picture of what I'm trying to do:
Code:
Now I want to call refreshScreen, but I don't know how:
My site has a widget that runs by calling an external script on a server outside my control. Normally this runs within a div as the page loads and the widget is displayed within the div.
What I am trying to do is call the script AFTER the page loads rather than while it loads. To do this, I am adding the script to the DOM (in the div I want, not to the head) on window.onload. An alert shows that the script is being created in the div.
The problem is that the script does not appear to fire in IE6 and IE7. In Firefox it runs, but rather than adding the widget to the div, it creates a new page (everything else on the page is lost).
I have made a test page to show the problem, as well as another page showing how the widget normally loads when the called while the page is loading. Code:
13 line causes this exception. Function is called insied of ready() handler. function renderGridSystemRecursively(scheme, container){

I am trying some simple things with javascript and trying to use it in a object oriented way. However I am now facing a problem in which I can't access an object variable from an object method. I am using jQuery.
My code is as follows;

I have two result. SelectableChildren: groupHead.nextAll(".SimpleButton") and SelectableChildren: groupHead.nextAll(".SimpleButton").next().children(".SimpleButton")
I would like to combine them into one object so that I can bind a handle to them in one loop. $.each(combineResult, function(index, object){ ... })
I have to make them in one, so that I can pass it around.

How do I create a new tag with jquery? I tried something like this:
link = $('a').attr({
class: 'logoLink',

$.ajax({
url: "validate_livestock_form/index/",
type: 'POST',

View 1 Replies View RelatedIs there a jQuery equivalent for the traditional:
document.createElement('span')
Because I'm trying to attach a stylesheet using jQuery. So far all I've found is the add() method, so I've put this together:
$(document).ready(function() {
$('head').add('link').attr('type', 'text/css', 'href', 'script/fancybox/jquery.fancybox-1.3.1.css', 'media', 'screen');
})
But the element will not get added, I presume it's meant to go before the ending '</head>' tag?
I have a tab compopenet object that works by passing a dom element to a constructor... which then finds all the relative elements to that element using .find() and adds the necessary behaviour. Now, since I have multiple tab components on the same page, I'm using each() to iterate through the dom elements and pass each into the tab component constructor function.

I've been trying to find out if jQuery has any functionality that can help me with creating bbCode style buttons (ie, like on this forum, click B and a [ b ] tag appears, second time creates a closing, or if you have text highlighted, it wraps it). I've tried Google-ing a lot, and randomly found this forum.I found/modified code using standard javascript a while ago,but I'd like to find out if jQuery has any funcionality that can help, mostly to learn.
