我对Javascript很新。我正在处理这个视图，所以按钮提交应该保存数据，如果文本框是空的，则有一个错误的javascript部分应该回复一个bootstrap aler No Data。但在所有情况下，无数据警报都不会显示，只有成功警报，即使这些字段中的字段为空。我会恳请每一个帮助。
<script src="~/Scripts/jquery-1.10.2.min.js"></script>
<script>
$(document).ready(function ()
{
$("#btnSubmit").click(function () {
var data = $("#myForm").serialize();
var newUrl = '@Url.Action("Index","AspNetUsers")';
$.ajax({
type: "POST",
url: "/AspNetUsers/Index1",
data: data,
success: function (response) {
$('#your-modal').fadeTo(2000, 500).slideUp(500, function () {
$('#your-modal').slideUp(500);
window.location.href = newUrl;
// $('#your-modal').modal('toggle');
// $('#your-modal').show();
//$('#your-modal .btn-default').click(function () {
// window.location.href = newUrl;
});
// window.location.href = 'Url.Action("Index", "Pages")';
//window.location.href = "/{controller}/{action}" //in your case, /employee/empl
// window.location = "//www.aspsnippets.com/";
// }
// alert("done");
},
error: function (response) {
// alert('No Data ');
$('#your-modal2').fadeTo(2000, 500).slideUp(500, function () {
$('#your-modal2').slideUp(500);
});
}
})
})
})

除非你的Asp脚本响应HTTP错误，否则不要期望调用JS错误回调。
大多数现代Web框架都可以帮助您进行客户端验证（但绝不依赖它）。或者您可以尝试编写自己的：
$('input').each(function(k, v) {
var v_val = $(v).val()
if (v_val == null || v_val == "") {
alert("Fill required field" + $(v).attr("name"))
}
});
像这样......
