IE 8 does not support foreach method

Question

This code does not work in Internet Explorer 8.

documenttab.query('.field,.button').forEach(function(c){c.setDisabled(false);}); 

I get error SCRIPT438: the object does not support the property or method 'forEach'

Answer 1

Ext has a forEach method. Where supported, it will defer its method:

http://docs.sencha.com/ext-js/4-1/#!/api/Ext.Array-method-forEach

 Ext.Array.forEach(documenttab.query('.field,.button'), function(c){ c.setDisabled(false); }); 

Answer 2

Mozilla also publishes code for methods that you can install near the top of your JS, and it will create them if they do not exist.

Answer 3

I believe this should solve your problem.

 vals = documenttab.query('.field,.button') for (i = 0; i < vals.length; i++) { vals[i].setDisabled(false); }
