JQuery :: Can't Access Object Variable From Object Method
Mar 10, 2011
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 need to acsess an object property via variables, but don't get ahead.
Example:
var property = height;
"height" is a property of the object "flower". Now, I need a possibility to access "flower.height" with my variable property, means -->"flower.property" I tried everything like "flower.[property]" "flower.['property']" etc. but nothing did help.
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;
//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.
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]
and addClickEvent sets the onclick attribute of above mentioned DIV. and in addClickEvent I am explicitely mentioning the name of class object. This means every time I create a Variable with another name I have to Change this function also.
how can I detect if mouse cursor is over or out of some element? I am running a animation, which I don't want to run or to stop itself if cursor gets to area.
Now we have alerts only for three old elements. This is clear. Because these elementes have been initiated before page generated. But the new one is ignored.
The question is - how i can add new elements to the UL list? It would be glad if "jQuery.each" could read four and more elements - not just the first three initiated elements.
I've created an object with properties and methods. The object is associated with a form. The object iterates through the form and finds any inputs that are required. It then uses each to apply validation to each of the found inputs. From within each(), I need to access properties and methods of the parent object, but now this refers to the current collection object. How do I access the containing object?
If "this" inside of a sortable "receive" function refers to the receiving object, How do I access the object to which the receive function belongs?
Example: // Function that takes a JQ object and makes it sortable. // We assign the "SortableRecieve" method to the receive event MyObject.prototype.MakeSortable = function(JQOBJ){ JQOBJ.sortable({ receive: this.SortableRecieve });}
MyObject.prototype.DoSomething = function(){ // Does something important } // The actual function that gets called when the receive event occurs MyObject.prototype.SortableRecieve = function(event, ui){ // This function call won't work, because "this" // doesn't point to the right thing! this.DoSomething(); } So how can I access the "True" this that refers to the object?
Now, if I want to get all the list items after the first, and change the text within the anchor tags, if a certain condition is met (eg change to capitals if it starts with a "t"). How can I do that? My approach was to get all the list items (after the first) with
I am trying to use some really simple jquery in a rails 3 app. I am trying to get a function to run whenever a rails 3 js callback is fired, the function is to add or remove css classes from link elements. But so far I keep getting errors in the console (chrome) stating that the object defined by my css selectors doesn't have the addClass and removeClass methods.Here is my code:
$(function($) { var resetArtistTabStates = function () { $("#artist-tabs li a".addClass("current"));
[code]....
The ajax:success event come from rails.js jquery file, which contains the following:
callRemote: function () { var el = this, method = el.attr('method') || el.attr('data-method') || 'GET',
I'm trying to send my array object through ajax using the jQuery .get method, but when it sends, ids show up as multiple parameters and I'm not sure if that's the way to do it.
Here is my code: var val = []; $(':checkbox:checked').each(function(i){ val[i] = $(this).attr('id').substring(6); }); $.get("/assets/ajax/pm_change_status.php", { s: sess_id(), 'ids[]': val } );
I am trying to access my own JS object from within an ajax call, and can't figure out how to get it to work Whenever I access "this" in the function, it returns the ajax context and not my JS object context. My code looks something like this. I have a Zone object defined in a JS file like this:
IE7 & IE8 refuse to run this code that must reposition a crosshairs over a street map. The crosshairs can be dragged and dropped only once. The second time I attempt to drag the crosshairs, nothing moves but this message appears: "object doesn't support this property or method" on the sentence posx = pos.left; By the way, the class crosshairs has position:relative.
I am trying to display a pop up window but keep getting the error above. Here is the rendered code: <head><title></title> <link href="/Content/Site.css" rel="stylesheet" type="text/css" /> <script src="/Scripts/jquery-1.5.1.js" type="text/javascript"></script> <script src="/Scripts/jquery-ui.js" type="text/javascript"></script> <link type="text/css" href="/asset.axd?id=lAAAAB-.............." rel="stylesheet"/> <script type="text/javascript"> $(document).ready(function () { $('#btnPopup').click(function () { $('#mypopup').dialog(); <======= ERROR });}); </script></head>
Is there a Jquery method I could use to quickly parse a JSONP object, looking for an embedded object called "error" ?? If I were to do the following: jQuery.each(query.data.error, function(i,error){ //....} And there wasNO .error in the returned JSON, what should I expect to happen? Basically, I want to know if "error" is in the JSON and process accordingly.
I'm running into an IE7 problem where the Visual Studio debugger is saying:"Microsoft JScript runtime error: Object doesn't support this property or method".Visual Studio is highlighting this line as the problem:[code] I then trim/lowercase it.The pertinent code block is below, the "lis" are list items I'm iterating over, I'm checking if the text of the li is equal to a dynamically populated hidden form field on the page.Code all works fine in Firefox, but throws errors in IE.[code]
I am having a problem with my jQuery. I am trying to get a plug-in called SlideDeck to work but the accordion will notslide. I found that jQuery is getting this Uncaught TypeError: Object #<an Object> has no method 'swing' on line 155. Everytime I click a slide to slide the repeat count goes up. Why I would be getting this error? I am using the enque script from wordpress and I am using jQueryopposedto the $ sign. Every other jquery code works fine.
I'm developing a website and am testing in IE 8 and am getting an error "Object doesn't support this property or method" for https:[url].... when I click on the error message on the lower-left of the browser window.This error comes on only when I am at the home page, then if I click on Lawn Care on the right. It is supposed to highlight the word and scroll to it. It is fine if I'm already on the Maintenance page.The site works in all browsers except IE 8.
Can you help me with this. Browser IE 6 and JQuery 1.4.4
Error is at this line$("#form0").validate({ rules: { issueCheckBox: { selectNone: true}} }); in document.Ready function. If code is not properly formatted please see the attachement. Script.txt
