Event handlers inside a Javascript loop – need a closure?

by

You do, indeed, need to implement a closure here. This should work (let me know – I didn’t test it)

var blah = xmlres.getElementsByTagName('blah');
for(var i = 0; i < blah.length; i++) {
    var td = document.createElement('td');
    var select = document.createElement('select');
    select.setAttribute("...", "...");
    select.onchange = function(s,c,a)
    {
        return function()
        {
            onStatusChanged(s,c,a);
        }
    }(select, callid, anotherid);
    td.appendChild(select);
}
