onchange / onclick in a checkbox doesn't work in IE

Question

I have the following code, which works perfectly in Chrome/FF:

chkbx_send_demo.onchange = function(){
    if(sel_template.selectedIndex <= 0 && ch         


        

Answer 1

my JS code is now something like this:

if(navigator.appName == "Microsoft Internet Explorer"){
            alert("IE");
            chkbx_send_demo.onclick = function(){
                alert("HI");
                if(sel_template.selectedIndex <= 0 && chkbx_send_demo.checked == true){
                    alert("Choose a Template");
                    sel_template.selectedIndex = 1;
                }
                if(chkbx_send_demo.checked == false){
                    alert("HI");
                    sel_template.selectedIndex = 0;
                }
                alert("HI");
            }
        }
        else
        {
            chkbx_send_demo.onchange = function(){
                if(sel_template.selectedIndex <= 0 && chkbx_send_demo.checked == true){
                    alert("Choose a Template");
                    sel_template.selectedIndex = 1;
                }
                if(chkbx_send_demo.checked == false){
                    sel_template.selectedIndex = 0;
                }
            }
        }

No javascript errors, but the code just isn't executed on IE and i really can't understand why.
