How do I store an object reference inside a variable when I want the object reference to to reference the first "ul" html element nested inside the current object (as referenced by this keyword)?
var slideList = ???
I am trying to create a sliding menu.
Well, it turns out IE8 has yet another problem. My code has a global variable (to the object) inside an object declaration that cannot be accessed by a function (that is also global).
The code is like so:
Code:
function myobject(params){
//public
this.initialize = function(){...}
//private
some variables...
//problem variable
var mouse = new Object()
mouse.x = 0;
mouse.y = 0;
//code...
slidecontainer = document.createElement("div");
slidecontainer.onmousemove = function(event) {
if(boo.isIE) {
e = window.event;
mouse.x = e.x + document.body.scrollLeft;
mouse.y = e.y + document.body.scrollTop;
} else {
e = event;
mouse.x = e.clientX + document.body.scrollLeft;
mouse.y = e.clientY + document.body.scrollTop;}}
//this function is in an interval
function moveslides() {
/* this is where I have the problem
It seems that the function doesn't recognize that mouse.x, or mouse for that matter, exists. Mouse is global to the object, so why can't this function access it?
*/if(mouse.x) {
code...
}}}
The page is at [URL] and works on every browser, including finnicky opera, except for ie. The full code is availabe when you right click and view the source on the page.
every time I try and alert:
[ { number:0, secondnumber:0 }, { number:2, secondnumber:1 }, { number:1, secondnumber:2 } ]
it just shows [object object], [object object], [object object]. Why is this and what can I do to make the record be shown as it is above in an alert?
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;
Code:
My problem is that the variable msg1 does not work when accessed from function called from the jQuery get function. I get the message undefined. Therefore I am wondering, is there a way how I can access msg1 of my object instance from the get function of jQuery?
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]
I am trying to read all the navigator object elements
1. Using the navigator.length returns undefined, cant use for loop;
2.Using and array of known elements like
var a = Array("appCodeName","appName","appVersion");
I seem to miss something to get it combined like navigator.a[i]
I have something that's called with AJAX when the user enters some text [url]. What I want is to execute some javascript within this "frame". If the frame calls something, with say <script type="text/javascript"> document.write('h'); </script> in it, then "h" doesn't appear, and neither does anything besides what would normally be shown if I didn't add that.

is there a delete for a object inside the constructor, while i init it?
i will try something like that:
var obj = function(a)
{
if (!a) delete this;
this.a = a;
}
I have a complex JS object. It manipulates the page DOM. Inside it I have many repetitive selections spread across functions. I would like to cache the selectors to enhance performance. How do other people do this? I can cache on the function level but not the object. When I try to cache on the object level I seemingly end up with stale selectors that while defined don't actually work.
My gut is that I can only cache on the function level?
what I have read does not deal with caching inside a JS object.

I've tried to debug it in firebug, but I guess there is a problem with the scope of the 'this'. The 'this' in
//i want append div with id of the name property of jgallery class
$("<div></div>").appendTo("#container").attr("id",this.name);
seems to refer to the iterator in the $.each().
I've tried to do this.this.name but it still doesn't work. Is there any way to allow me access the property of the Jgallery class?
I'm trying to use jQuery to get the two-letter country abbreviation from a URL that does exactly this. You give the URL your IP address, and it spits you back the string. Try it: [URL] When I try to get this to display on my page using jQuery, however, all I am getting back as the "data" is "[object XMLHtttpRequest]". I am thinking this has something to do with the fact that it's not coming back as HTML? It's just "US" as a plain text string. Does this make a difference? Here's my code:
jQuery.ajax({
type:"GET",
url:"http://nl.ae/iptocapi.php",
datatype:"html",

I am trying to implement the PowerZoom script inside of FancyZoom. The scripts work fine when called separately, but if I try to call PowerZoom inside of the FancyZoom object nothing happens. I get no errors from the pages and the console is clean.Is it possible to call a function from a dynamic object? Here is a test page to see what I'm trying to do.
View 3 Replies View RelatedHere's my object constuctor:
function suggest_object(result_id)
{
this.in_result_div = false;
this.search_element = document.getElementById(result_id);
}
And the execution code:
var suggest = new suggest_object(result_id);
document.getElementById(result_id).onmouseover = function(){suggest.in_result_div = true;}
It works as is, but i'd really like to be able to set the onmouseover inside of the object. Something like
function suggest_object(result_id)
{
this.in_result_div = false;
[Code]....
So how can I get the 'this' inside the onmouseover function to refer to the object?
I simply need to reference an object inside an iframe:
I need it to work on all browsers as I understand this is difficult for this type of command.
Why does the below code not work in ANY browser let alone all of them.
I have tested in IE8 and FF3 (not IE7).

<iframe name="iframe1" id="iframe1" src="file2.html"></iframe>
<script>
parent.iframe1.form1.obj1.disabled=false;

var $obj = $(this);[code]....
When the check box is checked (onload, click or keyup), if the table has a specified selector then i want to change the background color. I already have a working sample that i am converting to plugin. Since, my selector is at the table level, how can i find the checkboxes that are inside tr and td?
Trying to add a new property to a non-jQuery object from inside each loop doesn't appear to work:
var arguments=new Object();
arguments['ticket']=ticket;
arguments['email']=email;
arguments['module']=module;
arguments['epoch']=new Date().getTime();
var total=0;
$('select.category').each(function(){
var name=$(this).attr('id');
var option=$(this).find('option:selected').val();
total+=parseInt(option);
arguments[name]=option;
});
The 'total' variable works as expected. The the 'arguments' variable doesn't. Almost like
a variable scope issue or something. If I put some extra debug code to print out all the
property/value pairs, outside each loop I only see original four, and inside each loop only
the new one just set and none of the original four.?
Is it possible to test whether two objects are equal using the data they contain inside and not comparing their pointers with ==?
Well actually of course there is but...
Is there a way to do it without actually looping through the object, instead maybe something that came with JS? (something like a .equals() method from other programming languages.)
I am using objects in JS and I am trying to add draggable() into a DIV that works when I move the function out of the object context.
Example:
Code:
That does not work. However, if I do this:
Code:
Then it will work... because the draggable() function is not within the object.
I need this to work within the object, because I will have several DIVs associated with objects and I need them to have draggable() in specific cases.
I have a JS HTML editor (not a WYSIWYG) that I downloaded and it works fine, except that any input with quotes causes it to break. I need the quotes for things like HTML and CSS classes etc.If I have quotes inside the onClick, it fails completely with an Object expected error. If the quotes are escaped with a , I get an "unterminated string constant" error, with this showing where a button should be

what I have is this function which reads the JSON attributes of crab_house, a JSON object:
But what I would like to do is something like:
I have a function that takes parameters of what the form name and the form object name is and then modifies the form accordingly. Now I can make it work fine if i make a separate function for each form object, but that seems very cumbersome. This is what I have
document.formName.formCat.selectedIndex;
i want formName and formCat to be variables so I can specify in the parameters which part of the form to deal with, but i get an erorr. Is this possible?
How can you use an integer as an object? The idea is to create dynamic object according to a particular id which is an integer
var newObject = function(integer) {
window.integer = {};
}
I cannot console.log(window.123), only console.log(window.integer) ...
how I create the object window.123 or perhaps, window.id_123 ?
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?
How is it possible to take the value of a variable (in this case,
MODE_CREATE, MODE_UPDATE, etc) and use that as an object property name?
In the following example I want 'oIcon' object to have the properties:
mode1, mode2, and mode3.
This seems simple but I can't quite figure it out...
Any ideas anyone?
var MODE_CREATE = "mode1";
var MODE_UPDATE = "mode2";
var MODE_DELETE = "mode3";
var oIcon = {
MODE_CREATE: "create.gif"
, MODE_UPDATE: "update.gif"
, MODE_DELETE: "delete.gif"
};
var oTitle = {
MODE_CREATE: "Create a new item..."
, MODE_UPDATE: "Update this item..."
, MODE_DELETE: "Delete this item..."
};
