Hi all I have written the following script to get the value from the textbox which is in GridView but I am getting some value as NaNcan some one tell where I went wrong
This is my sample script
var grid = document.getElementById("<%=grdInvoice.ClientID%>");
var inputs = grid.getElementsByTagName("input");
for (var i = 0; i < inputs.length; i++) {
if (inputs[i].type == "text") {
if (inputs[i].name.indexOf("txtAmount").value != "") {
alert("Not Null");
amnt = parseInt(inputs[i].name.indexOf("txtAmount").value);
alert(amnt.toString()); // Getting Nan here
//var v = document.getElementById('<%= lblTotal.ClientID %>').value;
}
}
}
My grid is as follows
ddl Quantity desc Rate Amount
1 d 10 10
2 d 20 40
Like that some empty rows will also be there I need to sum the Amount and display
My grid view

My original script initially I will add AMount in the grid view based on user quantity after that I Would like to display the total amount in the grid to a label
<script type="text/javascript">
function multiplication(txtQuantity, txtRate, txtAmount) {
var weight = document.getElementById(txtQuantity).value;
var rate = document.getElementById(txtRate).value;
document.getElementById(txtAmount).value = weight * rate;
var amnt = 0;
// var Grid_Table = document.getElementById('<%= grdInvoice.ClientID %>');
// for (var row = 1; row < Grid_Table.rows.length; row++) {
// var qty = 0;
// for (var col = 0; col < Grid_Table.rows[row].cells.length; col++) {
// var cellcollectin = Grid_Table.rows[row].cells[col];
// for (var j = 0; j < cellcollectin.childNodes.length; j++) {
// if (cellcollectin.childNodes[j].type == "text") {
// if (cellcollectin.childNodes[j].name.indexOf("txtAmount") > 1) {
// if (cellcollectin.childNodes[j].value != "") {
// qty = parseInt(cellcollectin.childNodes[j].value);
// amnt = amnt + qty;
// }
// }
// }
// }
// }
// }
var grid = document.getElementById("<%=grdInvoice.ClientID%>");
var inputs = grid.getElementsByTagName("input");
for (var i = 0; i < inputs.length; i++) {
if (inputs[i].type == "text") {
if (inputs[i].name.indexOf("txtAmount").value != "") {
alert("Not Null");
amnt = grid.rows[i].cells[1].childNodes[0].value;
//amnt = parseInt(inputs[i].name.indexOf("txtAmount").value);
alert(amnt.toString());
//var v = document.getElementById('<%= lblTotal.ClientID %>').value;
}
}
}
document.getElementById('<%= lblTotal.ClientID %>').innerHtml = amnt.toString();
}
</script>
After all here is the solution
