Uncaught SyntaxError: Invalid regular expression flags（看页面源代码）
一、总结
js或者jquery方面的错误看页面源代码，一下子错误就很清晰了
二、Uncaught SyntaxError: Invalid regular expression flags
页面用jquery中的ajax的时候出现这个错误
$(document).ready(function(){
$("#b01").click(function(){
htmlobj=$.ajax({url:"/jquery/test1.txt",async:false});
$("#myDiv").html(htmlobj.responseText);
});
});
网上找的解答是：
@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.
看了下页面动态html转换成的静态html（通俗说就是页面源代码）：很容易就发现错误了
三、其它错误参照
问题：
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 .
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);
}
});-

- 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
