How can I open the new window after submit() finish

[gracelyn]

There is a 'save' button, and hope after user clicking it, the page save all the form's property value, then rediect to another page or open a popup window.
But, sometimes, b'cas the action have a little bit slow, so before action finished, the new window was opened and form's property are lost. How can I resovle it. How can I open the new window after submit() finish?

My script is:

function saveData(){
document.forms[0].mode.value = 'Save';
document.forms[0].submit();
}

function saveBtnOnclick()
{
if (confirm("Please save the data first.")){
saveData();
return true;
}else{
return false;
}

var newwin = null;
var newwinURL = "<%=appContext%>/do/....";
newwin = window.open(newwinURL, "addNewContact", "width=800,height=500,scrollbars=yes,toolbar=no,bo rder=0,status=0");
newwin.focus();
}

What is the reason for redirecting to a new window after the form data is submitted?
