I have a
<asp:RegularExpressionValidator>onkeydown="return jsDecimals(event);"jsDecimals() function, the validator stops working. What could be causing this issue?
ASP Code
<asp:TextBox ID="TextBox2" runat="server" CssClass="form-control" CausesValidation="true" MaxLength="13" onkeydown="return jsDecimals(event);"></asp:TextBox>
<asp:Button ID="Button5" runat="server" Text="Retrieve" CssClass="btn btn-default" OnClick="Button5_Click"/>
<asp:RegularExpressionValidator ID="RegularExpressionValidator1" runat="server" CssClass="tooltip-arrow"
ErrorMessage="ID must be 13 Numeric characters" ControlToValidate="TextBox2" ValidationExpression="^[0-9]{13}$">
</asp:RegularExpressionValidator>
JavaScript:
function jsDecimals(e) {
var evt = (e) ? e : window.event;
var key = (evt.keyCode) ? evt.keyCode : evt.which;
if (key != null) {
key = parseInt(key, 10);
if ((key < 48 || key > 57) && (key < 96 || key > 105)) {
if (!jsIsUserFriendlyChar(key, "Decimals")) {
return false;
}
}
else {
if (evt.shiftKey) {
return false;
}
}
}
return true;
function jsIsUserFriendlyChar(val, step) {
// Backspace, Tab, Enter, Insert, and Delete
if (val == 8 || val == 9 || val == 13 || val == 45 || val == 46) {
return true;
}
// Ctrl, Alt, CapsLock, Home, End, and Arrows
if ((val > 16 && val < 21) || (val > 34 && val < 41)) {
return true;
}
if (step == "Decimals") {
if (val == 190 || val == 110) { //Check dot key code should be allowed
return true;
}
}
// The rest
return false;
}
