How To Programmatically Send Multiple Email

I am programatically trying to send multiple emails from within javascript code. The problem I am having is as follows:
- In one try - I am using window.location="mailto:"+emailList - this works great if it only needs to generate 1 email, but I am doing it in a loop. when it loops through the 2nd time, it does not create a 2nd email
- In a 2nd try - I am using window.open("mailto:"+emailList - this does open multiple emails, but it also opens multiple windows.
I am trying to find a way to either not have the windows open (only the multiple emails) or automatically close the extra windows. I am including my code below - note - the window.location try is listed, but commented out.

if (emailListArray.length > jsNumEmails) {
var j=1;
for (var i=0; i<emailListArray.length; i++) {
partialEmailList = partialEmailList + ";" + emailListArray[i];
if (j == jsNumEmails) {
//window.location="mailto:"+partialEmailList;
window.open("mailto:"+partialEmailList, "temp", "height=5, width=5, top=0, left=0");
j = 0;
partialEmailList = "";
} //if
j++;
}//for
}
// if anything left in the partial list, then send that separately
if (partialEmailList != "")
{
//window.location="mailto:"+partialEmailList;
window.open("mailto:"+partialEmailList, "temp", "height=5, width=5, top=0, left=0");
}
