i have tried add js method to vf page with parameter and call this method with 'this' attribute in tag like onchange="calc(this)" but did not work.

Answer 1

i changed my code like this and it works.

vf page:

<apex:input id="qua" onchange="calc(this)"/>

js code:

function calc(p){
    var qua = p.value;
    var row = p.parentNode.parentNode;
    var pack = row.cells[6].innerHTML;        
    row.cells[7].innerHTML = qua * pack;
}
