Controlling Delete Or Update Of Records Using Checkboxes

I have checkboxes (Delete and Update) on a table.
update delete id
- - xx
- - xx2
n n n

The code below makes sure only one of the two check boxes are checked at a given time. So, either you can delete or Update but can't do both at the same. Now, in addition to current functionality, I need to be able to delete or update more than one record - How can I do this.

function Check(pass){
var divElement=document.getElementById('mytble');
var arrCheckElements = divElement.getElementsByTagName('input');
for(var i=0;i<arrCheckElements.length;i++){
arrCheckElements[i].checked =false;
} document.getElementById(pass).checked =true;
}
<td><input type=checkbox id="chkde" onclick="Check(this.id)" value=""></td>
<td><input type=checkbox id="chkup" onclick="Check(this.id)" value=""></td>
