javascript - IE8 Object doesn't support this property or method (Math.max.apply)

Question

I'm not a huge JS writer - so this maybe really easy - but I'm getting the above error in the following line of code:

max_height = Math.max.apply(Math, this.headlines.map(function(e) {
        return jQuery(e).height(); }));

Its not my code - but any pointers on how to fix this would be appreciated! Thanks

PS. works perfectly on Chrome/Safari...

Answer 1

My first (only) observation, is that you're using .map() which is defined in Javascript 1.6 and IE8 only supports Javascript 1.5 (as far as I'm aware)

Perhaps try using a polyfill or a library of pollyfils like modernizr etc. See: https://github.com/kriskowal/es5-shim

Or.

Write your code such that it doesnt rely on features unsupported by IE8.

Or.

Seeing as you're using jQuery. you could use jquery to provide the .map() functionality, see: http://api.jquery.com/jQuery.map/

max_height = Math.max.apply(Math, jQuery.map(this.headlines, function(e) {
    return jQuery(e).height(); }));
