                                  'GridView1_ctl04_TBPrice',
                                 'GridView1_ctl05_TBPrice');
var grdTBNumber_Txt = new Array('GridView1_ctl02_TBNumber',
                                'GridView1_ctl03_TBNumber',
                                 'GridView1_ctl04_TBNumber',
                                'GridView1_ctl05_TBNumber');
var grdTBSubtotal_Txt = new Array('GridView1_ctl02_TBSubtotal',
                              'GridView1_ctl03_TBSubtotal',
                             'GridView1_ctl04_TBSubtotal',
                              'GridView1_ctl05_TBSubtotal');
function validate() {
    var sum = 0;
    var num = document.getElementById("TextBox2");
    for (i = 0; i < grdTBPrice_Txt.length; i++) {
        var Obj1 = document.getElementById(grdTBPrice_Txt[i]);
        var objTBNumber = document.getElementById(grdTBNumber_Txt[i]);        var grdTBSubtotal = document.getElementById(grdTBSubtotal_Txt[i]);        grdTBSubtotal.value = Obj1.value * objTBNumber.value;
    }
    for (i = 0; i < grdTBSubtotal_Txt.length; i++) {
        sum = sum + parseInt(document.getElementById(grdTBSubtotal_Txt[i]).value);
    }
    num.value = String(sum);}以前写的东西你看看有没有用
