Uncaught SyntaxError: Invalid regular expression flags（看頁面源代碼）

一、總結

js或者jquery方面的錯誤看頁面源代碼，一下子錯誤就很清晰了

二、Uncaught SyntaxError: Invalid regular expression flags

頁面用jquery中的ajax的時候出現這個錯誤

1 $(document).ready(function(){
2   $("#b01").click(function(){
3   htmlobj=$.ajax({url:"/jquery/test1.txt",async:false});
4   $("#myDiv").html(htmlobj.responseText);
5   });
6 });

網上找的解答是：

@Url.Action only returns the action url's string, without quotes around it.

You'll need to wrap that url in quotes.

Replace:

url: @Url.Action("ReturnMethodTest", "HomeController"),

With:

url: '@Url.Action("ReturnMethodTest", "HomeController")', // ^ ^

Otherwise, the file returned to the client will contain:

url: /HomeController/ReturnMethodTest,

Which isn't valid JS, nor what you want. The replacement gives the following result:

url: '/HomeController/ReturnMethodTest',

Which is a perfectly valid JavaScript string.

看了下頁面動態html轉換成的靜態html（通俗說就是頁面源代碼）：很容易就發現錯誤了

三、其它錯誤參照

問題：

public ActionResult ReturnMethodTest(int id) { string name = "John"; return Json( new {data=name}); }

I am trying to get data from this controller by using code below but I am getting Syntax error .

Can you please tell me what am I doing wrong?

$.ajax({ url: @Url.Action("ReturnMethodTest", "HomeController"), data: { id: 5, }, success: function (data) { console.log(data); } });

try this:url: '@Url.Action("ReturnMethodTest", "HomeController")' – Mohit Kumar Jul 13 '15 at 6:55
My Code looks like this $.ajax({ url: '@Url.Action("ReturnMethodTest", "Home")', data: { id: 5, }, success: function (data) { console.log(data); } }); And firebug throws "500 internal Server Error" /i59.tinypic.com/5y96ok.png – Da Artagnan Jul 13 '15 at 7:13
