推荐答案
我只是使用javascript部分来显示验证摘要提示框。
I am just using the javascript part to show the validation summary in a alert box.
<script type="text/javascript">
function Validations() {
var FullName, Address, alertText = "";
if (FullName = document.getElementById("<%=txtFullName.ClientID%>")) {
if ((FullName.value.length == 0) || (FullName.value.length == "")) {
if (alertText == "") {
alertText = "Please enter FullName \n";
}
else {
alertText += "Please enter FullName \n";
}
}
}
if (Address = document.getElementById("<%=txtAddress.ClientID%>")) {
if ((Address.value.length == 0) || (Address.value.length == "")) {
if (alertText == "") {
alertText = "Please enter Address \n";
}
else {
alertText += "Please enter Address \n";
}
}
}
if (alertText != "") {
alert(alertText);
return false
}
}
</script>
