Er 类用来存储错误信息 然后前台调用
public static class Er
{
public static string Msg { get; set; }
/// <summary>
/// 将错误信息存起来
/// </summary>
/// <param name="s"></param>
/// <returns></returns>
public static string G(string s)
{
Msg = s;
return Msg;
}
/// <summary>
/// 读取错误信息
/// </summary>
/// <returns></returns>
public static string P()
{
return Msg;
} }
创建一个ErrorMsg控制器 和 视图
public ActionResult ErrorMsg()
{
string ss = Er.P();
ViewBag.msg = Er.P();
return View();
}
视图
@{
ViewBag.Title = "";
Layout = "~/Views/Shared/_Layout.cshtml";
}
<div id="div" style="display:none">
<h2>@ViewBag.msg </h2>
<h3><a href="/Home/Index">返回首页</a></h3>
<p>给您造成影响，再次向您表示道歉！</p>
</div>
@section scripts
{
<script>
@if (ViewBag.msg!=null)
{
<text>
swal(
{
title: "错误?",
text: "@ViewBag.msg!",
type: "error",
showCancelButton: true,
confirmButtonColor: "#DD6B55",
confirmButtonText: "跳到首页",
cancelButtonText: "不",
closeOnConfirm: false,
closeOnCancel: false,
allowOutsideClick:true
},
function (isConfirm) {
if (isConfirm) {
window.location.href = "/Home/Index";
swal("请等待!", "正在跳转。。。", "success");
} else {
swal(
{
title: "取消",
text: "您取消了跳转.",
type: "warning",
confirmButtonText:"确定",
timer:
});
$("#div").show();
}
});
</text>
}
</script>
}视图用到了sweetalert 弹窗插件
下面是ajax的全局错误处理
创建一个 MyJs 的js文件
$(document).ajaxError(function (event, xhr, options, exc) {
if (xhr.responseText != "") {
var jsonValue = jQuery.parseJSON(xhr.responseText);
console.log(jsonValue.ErrorMessage);
swal(
{
title: "错误",
text: jsonValue.ErrorMessage,
type: "warning",
confirmButtonText: "确定",
});
}
})
