Gridview row validation on button click in javascript

Question

I am doing validation for gridview on button click.

My requirement is in gridview I can add multiple rows at a time. Suppose if I add 2 rows, In any of 2 rows there should be atleast a column with value PURCHASER then it satisfies my requirement.

But if in both rows there is not PURCHASER then it should prompt alert.

So what I wrote is

for (i = 0; i < GrdPartyInfo.Rows.length; i++) {
            if (GrdPartyInfo.Rows[i].Cells[3].Value != "PURCHASER") {
                alert('There should be atleast one purchaser');
                return false;
            }    
        }

But what happens is, if I add PURCHASER in second row it still prompts me error. WHY ?

You are just checking the first value, and if it is not a purchaser, you output the error, ignoring other values. Instead this should be:

var hasPurchaser = false;
for (i = 0; i < GrdPartyInfo.Rows.length; i++) {
    if (GrdPartyInfo.Rows[i].Cells[3].Value == "PURCHASER") {
        hasPurchaser = true;
    }    
}

if (!hasPurchaser) {
    alert('There should be at least one purchaser');
    return false;
}
