SepRestrict 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>
