#10159 closed bug (wontfix)

.outerHeight() returns positive value for <script> elements

Reported by: yelo3 Owned by: yelo3
Priority: low Milestone: None
Component: dimensions Version: 1.6.2
Keywords: Cc:
Blocked by: Blocking:


I think I have found a bug in the .outerHeight() jquery function. I'm trying to the the height of the children of <body>, and it appears that <script> tags have a height > 0 (in this case I get 20, in chrome browser). This is not expected: in my opinion they should have a height = 0.


<html> <head>

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.5.2/jquery.min.js"> </script> <script type="text/javascript">

$(document).ready(function() {

var children = $(document.body).children();

for (i=0; i<children.length; i++) {

height = $(children[i]).outerHeight(true); console.log("height=" + height);




</head> <body>

<script type="text/javascript"> var a=1; var b=2; var c=3; </script>


<p>hello1</p> <p>hello2</p> <p>hello3</p>


</body> </html>

Thanks for taking the time to contribute to the jQuery project! Please provide a complete reduced test case on jsFiddle to help us assess your ticket.

Additionally, be sure to test against the jQuery Edge version to ensure the issue still exists. To get you started, use this boilerplate: http://jsfiddle.net/FrKyN/ Open the link and click to "Fork" (in the top menu) to get started.

This happens because the width/height cssHook does a visibility swap when it encounters an element with no offsetWidth/offsetHeight. It reports a value because even style and script tags can get width/height when they are absolutely positioned and given display:block.

Two options:

  1. needsdoc that it reports weird values for style/script
  2. before visibilty swapping, detect nodeName "STYLE" or "SCRIPT", which begs the question of "what other elements should always report zero besides style and script?".

I'll open a PR just in case we want to go with option 2.

I'm inclined to say needsdocs. It seems pretty obvious that one shouldn't call width/height on style or script tags. And why loop through all of the elements on the page? I can't actually see where that would be useful.

Also is broken on input:hidden tags in chrome. I opened a PR just in case: https://github.com/jquery/jquery/pull/547

It's pretty small. Also, here's the perf... looks pretty good: http://jsperf.com/outerwidth-on-hidden-elements

  • Keywords needsdocs removed

Initial docs added to http://api.jquery.com/height/. I've pinged Dave and Karl about turning the notes into a reusable.
