问题描述
我使用此javascript作为字段验证器
I use this javascript as a field validator
<script type="text/javascript">
//Function to allow only numbers to textbox
function validate(key) {
//getting key code of pressed key
var keycode = (key.which) ? key.which : key.keyCode;
var phn = document.getElementById('txtPhn');
//comparing pressed keycodes
if (!(keycode == 8 || keycode == 46) && (keycode < 48 || keycode > 57)) {
return false;
}
else {
//Condition to check textbox contains ten numbers or not
if (phn.value.length < 10) {
return true;
}
else {
return false;
}
}
}
</script>
并将该功能添加到文本框
and add the function to the textbox
<asp:TextBox ID="txtTotal" runat="server" Width="131px" BorderStyle="None" Height="18px" onkeypress="return validate(event)"></asp:TextBox>
但是,当控件在gridview内部时,
例如文本框在gridview内,我该如何调用onkeypress事件?
However, when the control is inside a gridview,
for example the textbox is inside the gridview, how do I call the onkeypress event?
