Assign a Javascript function to AjaxOptions OnSuccess property raise an error - ASP.NET MVC
提问by segaco
I'm using the Ajax.ActionLink helper to generate a link to delete a record. This is the code:
我正在使用 Ajax.ActionLink 帮助程序生成删除记录的链接。这是代码：
Ajax.ActionLink("Delete Image", "DeleteImage", new { id = item.Id },
new AjaxOptions { HttpMethod = "Delete", OnSuccess = "Test()" } )
I'm assign a Javascript function (Test()) to the OnSucess property because I want to do some JQuery stuff, but when I click the Delete link this error message is raised
我将一个 Javascript 函数 (Test()) 分配给 OnSucess 属性，因为我想做一些 JQuery 的事情，但是当我单击删除链接时，会出现此错误消息
Microsoft JScript runtime error: 'b' is null or not an object
Microsoft JScript 运行时错误：“b”为空或不是对象
in the MicrosoftAjax.js file (Line 5, Column 62099). If I remove the OnSuccess property, everything works fine (even if the Test() function is empty, the same error is raised). Thanks for your help!
在 MicrosoftAjax.js 文件中（第 5 行，第 62099 列）。如果我删除 OnSuccess 属性，一切正常（即使 Test() 函数为空，也会引发相同的错误）。谢谢你的帮助！

OnSuccess = "Test()"
you have to write it like this it is a callback...
你必须像这样写它是一个回调......
OnSuccess = "Test"
回答by atzu
If you have to pass any parameter to the OnSuccess event you may have to write the funcion in this way.
如果您必须将任何参数传递给 OnSuccess 事件，您可能必须以这种方式编写函数。
OnSuccess = "function(){exampleFunction('" + param1 + "');}"
回答by Sam Peacey
To pass a parameter, an anonymous function won't work, you need to do something like this:
要传递参数，匿名函数将不起作用，您需要执行以下操作：
OnSuccess = String.Format("Test({0})", param)
