Restrict user to enter numeric value in textbox using javascript
Due to some reasons (like don’t allow to enter chars in Price TextBox), we restrict users to enter chars in TextBox. We can implement this functionality by using below method.
<script type="text/javascript">
function checkNumeric(event) {
var kCode = event.keyCode || event.charCode; // for cross browser check
//FF and Safari use e.charCode, while IE use e.keyCode that returns the ASCII value
if ((kCode > 57 || kCode < 48) && (kCode != 46 && kCode != 45)) {
//code for IE
if (window.ActiveXObject) {
event.keyCode = 0
return false;
}
else
{
event.charCode= 0
}
}
}
</script>
<asp:TextBox ID="TextBox1" runat="server" onkeypress="return checkNumeric(event); ></asp:TextBox>
