使用Windows 7 Professional而不是Windows 7企业版的IE9中的Javascript问题

Question

1. Is it possible to get a javascript related error only in IE9 with Windows 7 Professional and not in IE9 with Windows Enterprise?
2. Can there be any difference in the way IE9 behaves with respect to javascript between a 32-bit Windows 7 and a 64-bit Windows 7?

Please help me with this. The full javascript function is below.

function foo() {
    var isChecked = false;
    var checkBoxField = "MyCheckBox1";
    for(j=0;j<document.forms[0].elements.length;j++) {
        if(document.forms[0].elements[j].name.search(checkBoxField) == 0) {
            if (document.forms[0].elements[j].checked == true) { 
                isChecked = true;
            }
        }
    }
    alert(isChecked);
}

The isChecked variable has to be true when the checkBoxField is checked. It is true in IE9-Windows 7 Enterprise Edition (Not sure about 32-bit or 64-bit) and it is false in IE9-Windows 7 Professional Edition (32-bit)

Apologies. After looking at the IE settings in the exact machine where the issue occurs, it is clear that it is due to caching. The setting Preserve Favorites website data preserves the old js file and is not downloading the updated version (even if we try to clear cookies, history, temporary files etc). Once that setting is unchecked - history, cache cleared everything started working. Cheers,

There shouldn't be any difference in different windows version, since most time you'll be using 32 bit ie. But you never know what kinda of bug is in ie javascript

what you can try is is use jquery you code looks like

function foo() {
    var isChecked = $("name='MyCheckBox1':first").attr('checked');      
    alert(isChecked);
}

set your checkbox id to MyCheckBox1 and it further simplifies

function foo() {
    var isChecked = $("#MyCheckBox1").attr('checked');      
    alert(isChecked);
}

Not sure if it'll help you, but that's my 20 cent.
