Determining the height of a document with JavaScript presents difficulties on certain websites. On platforms such as Fandango and Paperback Swap, various JavaScript methods fail to yield accurate results.
The Problem
- $(document).height() returns the correct value for Fandango but throws an error on Paperback Swap.
- document.height and document.body.scrollHeight return incorrect or null values.
- Applying a padding-bottom to the element has no effect on these problematic pages.
The Solution: A Comprehensive Approach
To accurately determine document height, a comprehensive approach is required:
var body = document.body, html = document.documentElement; var height = Math.max( body.scrollHeight, body.offsetHeight, html.clientHeight, html.scrollHeight, html.offsetHeight );
This code calculates the maximum height value from all available options:
- body.scrollHeight
- body.offsetHeight
- html.clientHeight
- html.scrollHeight
- html.offsetHeight
Considerations
- Note that calculating document height before the document has loaded will always result in a value of 0.
- If you dynamically add content or allow the user to resize the window, you may need to recalculate the document height.
- Using an onload or document ready event will ensure accurate height calculation at load time.
