c# MVC控制器调用两次

本文关键字：两次 MVC 控制器 调用 | 更新日期: 2023-09-27 18:18:53

我正在制作一个面向Ipad的c# Razor MVC web应用程序。我正在使用JQuery移动和剑道UI。我有两个使用Kendo网格的输入表单，它们位于JQuery弹出窗口中。

我的问题是，Waste_Read控制器是双重射击，使2剑道网格。这在桌面应用程序中是不明显的，但在ipad 2上，网格是可见的。

下面是我的_Layout。cshtml和哈姆。CSHTML(这是我的视图)代码。

谢谢!

c# MVC控制器调用两次

唯一的情况下，我能想到一个表单张贴两次是当你有一个javascript函数绑定到你的提交按钮点击，然后调用form.submit()

如果这是你目前正在做的事情，那么在调用form.submit()

之前尝试执行e.p preventdefault。
$('#mySubmitButton').click(function(e) {
         e.preventDefault(); //This prevent the submit button onclick from submitting by itself
         $('#myForm').submit(); //Manually call the form submit
});
$('#myForm').submit(function(e) {
      e.preventDefault(); //Prevent default here as well - this will allow you to do 
                          //your own posts without the defaults running (good for when you want to use ajax)
     // Simple ajax post using whatever action you put in your form 
     if ($(this).valid()) {
           $.ajax({
                url: this.action,
                type: this.method,
                data: $(this).serialize(),
                success: function (result) {
                })
           });
     }
});

这将确保您的表单只执行一次

在更复杂的设置中，我注意到我的控制器被击中了不止一次。当我纠正了以下两点后，它不再受到双重打击:

  • 带有src="#"的IMG标签(用于延迟加载
    图像的占位符)javascript)删除标签==> src=""

  • @Url.Content("~/some/static/path/some.css")取消呼叫
    Url。内容==> "/some/static/path/some.css"(当然路径

实际上@Url.Content()再次击中控制器的原因并不清楚，但经过彻底的测试证明了这一点。
