i want the following var i="name";console.log({i:'value'}); o be equivalent to (as an end result)
var i='name'; var t={}; t[i]='value';console.log(t); is that possible?or must i use the second method?
I have the following code:
A = {
"value": "a",
};
B = A ;
B.value = "b";
alert (A.value); // => b
I expected A.value to be "a". how can I change values of a new object, without changing the parent-object?
I am having a terrible time getting the following code to work:
var foo = {
bar : "bar",
fooTwo : {
bar : foo.bar
}}
When this code runs, I am told that foo.bar does not exist in line 4. Why am
I getting this error?
Is it possible to have something like the following so that 'three'
can access 'one':
var x = {
one: 1,
two: { three:this.one } // Or parent.one ?
}
If not (which I have nearly come to a conclusion on) what is the next
best way to accomplish this?
I'm declaring a class in OLN:
Code:
The problem is that in IE, when I call myfunc() it complains with the error: Class is undefined
I'm not sure what I'm doing wrong. Class is declared in as much global scope as possible, and that shouldn't even matter in JS.
I'm trying to put a function in a object created using JSON notation. The syntax looks like this...
Code:
historySet = { ajaxRunFunction: "updatePageCopy('" + pageID + "','','" + pageName + "')"};
It works fine in FF, but in IE it calls the function updatePageCopy when it creates the object history set. I don't want to call the function when the object is created.
I am trying to get the index of a li with a specific class. I know I'm selecting the right object because I can apply a CSS class to it (eg change border colour) but when I try to get the index it returns -1. But I know the object exists as I can alter it. :-s
jQuery(document).ready(function() {
var active = $("#tertiarynavigation .bordered").get(0);
var num = $("#tertiarynavigation li").index(active);
alert("Index: " + num);

I'm having difficulties to understand why the code below doesn't work.
The idea is to generate an <iframe> with a higher z-index compared to
an <object>. In Microsoft Internet Explorer 6, everything works fine,
but Firefox/Netscape seems to have problems with this construction.
Am I overlooking something ? Code:
I have an array "arr" that is an array of objects. Each object has the same 7 properties.I want to find the index of the object with a property that matches a certain value x in the array arr. How can i accomplish this?The array has hash tables associated with it.arr [ obj [ i ] . property1 + "_" + obj [ i ] . property2 ] = arr [ i ] ;so whats the index of the object where .property1 = x ?
View 2 Replies View RelatedI'm building a webpage using javascript and iframes. Basically I have an iframe in the middle of the index.html page that links to another html page (let's call it iframe.html). My question is, is it possible to call a javascript function from iframe.html to control an object on index.html? If so, how do I do this? I'd like to be able to assign an image in iframe.html with the hyperlink of href="javascript:function()", where the function effects the CSS of a div on index.html.
View 2 Replies View RelatedI have difficulty understanding how square brackets work in JavaScript and this is causing me difficulty retrieving the values of the options of my Select controls.
My form contains many select boxes. Their names are stored in variables(in this case concat is the select control name) and I have no trouble accessing methods for the select object ie:
document.Allan.elements[concat].selectedIndex;
I would like to get the value of the selectedIndex but I am having difficulty because I don't know the right syntax. I'm looking for a statement like the one that follows but uses variables
document.form.theDay.options[2].text
Could some one help me use the right syntax?
I've started learning writing javascript objects with literal notation...
Instead of the usual syntax...
The problem is that it's hard for me to adapt procedures which I'm used to within the normal syntax for the literal notation. E.g:
Is this variable global or local? If it's local, how do I declare a variable globally? I also wonder if it is possible to bind events to objects from within the object? And if I'm correct - jQuery is coded this way, but how can they then make use of their selector:
When it is an object defined with literal notation that doesn't have a constructor?
I did some searching around, but didn't see this addressed directly. Here is an example of when dot notation fails in Firefox, and when SetAttribute doesn't fail: Code:

I have a problem with layers. In my example there's a link inside div#msg with 'z-index:1' and a overlay with 'z-index:2'. Now when "mousedown" fires, will change the div#msg z-index value from 1 to 3 to be on Top, so the link become a clickable link.
The question is, it is possible to make the link on top and open it with just one click?
This example can do that but won't open the link!
HTML Code:
I have a line which looks like this in PHP:
Code:
<input id="btnCancel$folder_id" type="button" value="Cancel" onclick="swfu.$folder_id.cancelQueue();" disabled="disabled" />
and of course when output looks like this:
Code:
<input id="btnCancel111" type="button" value="Cancel" onclick="swfu.111.cancelQueue();" disabled="disabled" />
It seems that the .111. throws an expected ";" error. swfu.cancelQueue(); by itself does not.
These objects are being defined in a function which takes in the folder ID as a variable, and then builds using this line:
Code:
swfu[folderId] = new SWFUpload(settings);
I just got this script for a countdown on a website and I got it to work locally but when I upload it to the server i get the error "index.html:22 Uncaught TypeError: Object [object Object] has no method 'fancycountdown'".
I have checked to make sure all other javascript files are loading and they are and I can't figure out whats wrong. You can see it [URL]

That code does not work! Even if I use parseInt it then it only shows NAN in the alert box.
I need to set tabs on java generated pages. Pages have four sections:
header, sidebar, body, and footer. The sidebar and body change dynamically.
The tab key must go to anchors, fields, and buttons doing all in the header

the pieces and has the body tag. Code:

Just started to dabble with jQuery I can get the id for a clicked element, but how can I retrieve its index number within the class?
Code:
$(".heading").click(function () {
$("#containContent").slideToggle(100);
//window.alert($("#containContent .content").length);
window.alert(this.id);
});
Hopefully I can do this from the 'this' reference without having to backtrack through the id?
