Answer 4

Change the method prototype as

function confirmUpload(obj) {
//Do some thing
}

Where obj the the button you are clicking on

Call this method as

**onclick="javaScript:confirmUpload(this)"**

Now in that if part call another method like

if (confirm("Are you sure want to upload '" + document.getElementById("txtWS").value
    +     "' ?") == true) {
    doSubmit(obj);
}
