I've been having this issue with Javascript that is just not getting resolved for a while. What I am basically doing is building a simple web browser extension that injects javascript on certain pages. I am using Firefox, Chrome and Safari. The issue I am having is accessing these so called "special properties" on a particular page. They look like the regular classNames, id, textContent and such but don't appear to be standard. It would be very helpful if I can access them.
A particular example would be in Yahoo Mail. When you are in your inbox you have list of messages. With each message row there are associated attributes. You can get to them with your web inspector or if you search for the div element with id "PagedTableView_wrapper", then follow the first child and then second child and you get a list of these messages being rendered. Each one of those rows has the regular className properties and such but also has "_checked", "_focused", "_selected" that look like custom Yahoo ones. I basically want to read those.
The issue is I can't. I always end up getting a null exception, as if it doesn't exist. I can read the className and the other standard ones fine, but not the special ones. (I've verified its the same element as well). I have tried the DOM navigation route with indexing, jQuery and XPATH, all with the same result. The weird part is that I can see them with the webInspector! Whats even more strange is that if I run firebug or commands in the Console, it actually works! But it doesn't work for my injected code/extension! Baffled.
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.
I'm having trouble accessing a custom property that I've created for an object. Does anyone see the problem with this code? this.imageSrcs is undefined inside of getImages.
Quote:
Gallery.prototype.imageSrcs = new Array(); Gallery.prototype.getImages = function(json) { if (json) {
This error ONLY occurs in IE. "Unexpected call to method or property access." I pinpointed it to this line: o.appendChild(e);
The full function is: function aO(d, t, src, p, id ){ alert('aO has begun.'); var o, e, i; if (!ie){ o = cE('object');o.data = src; } else { o = cE('embed');o.src = src; } .....
I have WordPress installed in a directory of my website, and I'm using an iframe on the homepage to embed the blog. I'm using a javascript code that I found online to automatically resize the iframe based on the content inside of it. This is the code:
<script type="text/javascript"> function resizeIframe() {[code]...
This works perfectly in Google Chrome. However, in Firefox I get this error in the console:
I don't have any experience with javascript, but this makes no sense to me, because it should work since the iframe document is on the same domain and server as the parent page. The parent is[url]...." and the iframe document is [url].....Why is Firefox complaining about this? It shouldn't violate the "same origin policy" that I have read about.
if the dt-element in one of the definition lists has a specific css-property (e.g. length > 100px) then the dd-element with the css-class "subtitle" in the same definition list should be removed.
I'm doing a very simple expand/collapse function using 'slideToggle'. The button that triggers this event simply says 'Expand/collapse'. I want this text to change depending on whether an element is visible or hidden.
I would like to be able to test if an element already has a style applied to it. This style might either be an inline style, or come from a stylesheet. I'm writing a plugin which needs to apply a CSS style to an element if it's not already there.
I ended up having to preset style with JavaScript.
Here is what I did.
CSS Code:
JavaScript Code:
HTML4Strict Code:
The first time I hit toggle, nothing happens. The second time I hit toggle, the hidden list appears, but only because I used JavaScript to set the display property.
My workaround is to do this in the HTML after the element to be toggled.
JavaScript Code:
Putting this code in the elements onload event property didn't work either, which I found odd, but I read that it was not the recommended way of doing this.
I can't figure out why the CSS declaration didn't load into the JavaScript HTML DOM. I suspect it's some sort of order of execution thing, like the difference between the two following function declarations.
I'm writing a script that dynamically generates a menu table. Each TD has an onclick property which serves as a link. Everything works properly in other browsers since setAttribute onclick works. However, this function does not work in IE, and you're supposed to do this instead: elementName.onClick = "blah";
Here's my code that works in all browsers but IE: Code: var truePath = "document.location.href=" + "'" + "/" + urls[i] + "'"; cell.setAttribute("onclick",truePath); cell.onclick = truePath;
For IE, if I set the cell.onclick value to truePath, nothing happens when I click on the menu. However, it works fine in Firefox and Opera because of the setAttribute function. How I could get this to work in IE? My script is complete besides this part... I hate IE. Why can't they follow the rules?
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:
I'm having an issue retrieving the height() / outerHeight() property of a div element that has an img as child. This happens only on chrome and safari. Here's an example: [URL]
For each element in the currently loaded markup page that has an 'id' attribute, elements can be accessed like-
var elem = document.getElementById("foo"); - ("foo" is the 'id')
now i want to implement a shorthand method which can give me the element just by this:
var elem = document.foo; -("foo" is the 'id');
For this , i will have to add properties to the global "document" object for each element in the currently loaded page that has an attribute. These properties should be added when a page is loaded , and should be removed when a page is unloaded..
How can i dynamically add and remove property to an object.
I insert an element into a website (between <div id=here></div>. It works.This is an input field and a picture (a trashcan)).Click on this picture shall delete the new content between the <div>s This doesn't work.Only on the content on bottom of the site (original content) works.
I am on a project that wont let me use jQuery, but i have grown so use to the jQuery structure i want to have similar syntax [code] i am aware that this is all it does and would die for any other use $('.bla'). thats ok, one step @ a time, all i need is ID selector right now (project has VERY limited scope)but now i want to recreate jQuery's the append():[code]if i had an append function in a normal function it would look like this:[code]the problem is in the jQuery "like" version i don't know how to access the node element?
I have a parent document which has an iframe loaded in it. The iframe has an textfield element. I want to access this textfield element from the parent document. I have tried the following. But that doesn't work.
(from the parent) window.frames['frame01'].document.getElementById('idname')
I built an IE-only function that modifies the DOM to create a custom container with rounded corners and some shading at the top. It only gets called when the browser is IE and its version is < 9. It takes the following block:
And turns it into this:
The UI looks identical to FF, which uses the CSS3 attributes to create the rounded box. HOWEVER, in IE8, I can no longer access the embedded <input> element (which does not change). I'm trying to get the value of the <input> tag with the ID of "username" by doing this:
When I disable my DOM manipulation code so that in IE, it remains an ugly, square box, I can get the value of the <input> element with no problem. Once I manipulate the DOM, IE always returns the empty string while FF and Opera work perfectly.
