getcomputedstyle

I am trying to use draggabilly available at https://github.com/desandro/draggabilly it works fine in html. Now when i have tried to add it in wordpress. I am getting following error in firebug console. TypeError: Argument 1 of Window.getComputedStyle is not an object. return s.getComputedStyle(t, null) here is a link for js file http://draggabilly.desandro.com/draggabilly.pkgd.min.js You are calling init twice. Go through your code and remove one instance. I received this error testing my project with IE8: finally it was so obvious, this method doen't work with IE 8! Error: Object doesn't

This was a surprise. The following code does not seem to give me the actual colors on the screen: h1 = document.querySelector("h1"); window.getComputedStyle(h1).color Gives rgb(0, 0, 0) which I think is correct. However window.getComputedStyle(h1).backgroundColor gives rgba(0, 0, 0, 0) . The actual background color I see on the screen is white. The element I call h1 is visible on the screen. I was expecting to get the actual background color. The value I get above (in rgba) is not wrong, but not very useful either. It just tells me the background is fully transparent - and that is not a color.

window.getComputedStyle give the style's value in Chrome, but in firefox and Microsoft Edge it gives an empty string and in Internet Explorer, it say that it doesn't support that method. Here is my code. Whenever the Upvote image is clicked it fires the upDownVote() function, passing two arguments. This is the HTML. <div id="upvote" title="Click to UpVote" onClick="upDownVote('increment',<?php echo $id; ?>);"></div> <div id="downvote" title="Click to DownVote" onClick="upDownVote('decrement',<?php echo $id; ?>);"></div> I passed three variables to my php script through ajax; Id, type,

I have this HTML page: document.addEventListener("DOMContentLoaded", function (event) { var inner_div = document.getElementById("innerDiv"); console.log(getComputedStyle(inner_div, null)["backgroundColor"]); }); #outterDiv { background-color: papayawhip; } <div id="outterDiv"> <div id="innerDiv"> I am an inner div </div> </div> I want to find out the computed background color of the inner div without having to look into parent(s) element's computed style. Is that possible? You apparently mean to ask How do I find the background color for some element which is used by virtue of that color being

In short: I am trying to understand the meaning of this TypeError: Failed to execute 'getComputedStyle' on 'Window': parameter 1 is not of type 'Element' The error appears while lunching Mediawiki's VisualEditor, as can be seen here: http://www.wiki.org.il/index.php?title=new-page&veaction=edit The error doesn't enables creating new pages or editing the wiki anonymously. However, with the use of a different skin the error disappears: http://www.wiki.org.il/index.php/Main_Page?useskin=vector The wiki runs on 1.25alpha. I had this same error showing.
