IE 8 does not support foreach method

Question

This code not working in Internet Explorer 8.

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

I get the error SCRIPT438: Object doesn't support property or method 'forEach'

Answer 1

Mozilla also publishes code for methods which you can put near the top of your JS and it will create them if they don't exist.

Answer 2

I believe this should solve your issue.

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

Answer 3

Ext has a forEach method. Where supported, it will defer to the native 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);
});
