问题描述
我试图让Ajax调用，像这样：
I'm trying to make an ajax call like so:
$.get('/home/myInfo', function (data)
{
....
});
When I try to make the above call, it goes to: http://localhost/myapp/home/index/home/myInfo
我想它去
我必须指定绝对URL？
Do I have to specify absolute URL?
推荐答案
绝对不会硬code网址，这样在ASP.NET MVC应用程序。使用URL处理时，必须使用网址帮手，就像这样：
Absolutely never hardcode urls like this in an ASP.NET MVC application. Always use URL helpers when dealing with urls, like this:
$.get('@Url.Action("MyInfo", "Home")', function (data) {
....
});
如果这是一个单独的JavaScript文件，你不能使用服务器端的助手，以及例如，你可以使用HTML 5的一些DOM元素上数据 - *属性TAT你AJAXifying，像一个div或东西：
or if this is in a separate javascript file where you cannot use server side helpers, well you could for example use HTML 5 data-* attributes on some DOM element tat you are AJAXifying, like a div or something:
<div id="mydiv" data-url="@Url.Action("MyInfo", "Home")">Click me</div>
和则：
$('#mydiv').click(function() {
$.get($(this).data('url'), function (data) {
....
});
});
或者如果你是一个AJAXifying形式或锚：
or if you are AJAXifying a form or an anchor:
$('#myanchor').click(function() {
$.get(this.href, function (data) {
....
});
return false;
});
在这里当然会一直使用助手产生锚：
where the anchor would of course have been generated using helpers:
@Html.ActionLink("click me", "MyInfo", "Home", null, new { id = "myanchor" })
看到了吗？无需辛苦code的URL。不这样做，因为它会在打破非常第二你修改你的路由的格局的Global.asax 。按照此方法的code将完全不可知的你的路由结构的任何更改。
See? No need to hardcode urls. Don't do it as it will break at the very second you modify the pattern of your routes in Global.asax. By following this technique your code will be totally agnostic to any changes of the structure of your routes.
