更新jQuery版本已经破坏了ajax负载。

I have an ASP.NET MVC application that uses jQuery 1.3.2.

我有一个ASP。NET MVC应用程序，使用jQuery 1.3.2。

On several of the pages there is a grid that lets you select multiple items, and then calls .load to load the details for the item.

在一些页面上，有一个网格允许您选择多个项目，然后调用.load来加载项目的详细信息。

this.$container.load(this.url, data, function() {
    // Show results
});

data containing an Array named s that contained the selected ids.

包含一个名为s的数组的数据，该数组包含所选的id。

s = [ "2", "1" ]

s = ["2"， "1"]

Using jQuery 1.3.2, data would be posted as

使用jQuery 1.3.2，数据将被发布为

s   2
s   1

Which was sent to

这是发送给

public ActionResult SomeAction(object[] s)

and everything worked great.

一切伟大的工作。

I tried to change the jQuery library to a more recent version (1.5.1) and now my controller doesn't receive the value of s because jQuery is posting data like so:

我尝试将jQuery库更改为最新版本(1.5.1)，现在我的控制器没有收到s值，因为jQuery发布的数据如下:

s[]   2
s[]   1

Do I need to assign an index in order for the controller to receive the value (s[1], s[2])? Do I need to change the controller action's signature or the way the array is generated? Right now the javascript to generate data is simply

我是否需要为控制器分配一个索引来接收值(s[1]， s[2])?我需要更改控制器动作的签名还是数组的生成方式?现在，生成数据的javascript很简单

var s = new Array();
for (var id in this._selected) {
  // Some checks
  s.push(id);
}

If it worked in 1.3.2, you should be able to revert to the old behaviour by setting jQuery.ajaxSettings.traditional = true. This is a change in jQuery 1.4, and this setting allows backwards compatibility.

如果它在1.3.2中工作，您应该能够通过设置jQuery.ajaxSettings来恢复到旧的行为。传统= true。这是jQuery 1.4中的一个更改，并且允许向后兼容。

See the manual entry for $.param for more details.

参见手册条目$。参数为更多的细节。

Using your example data:

使用您的示例数据:

var data = {s: ["2", "1"]};

// jQuery 1.7
$.param(data); // "s%5B%5D=2&s%5B%5D=1"
jQuery.ajaxSettings.traditional = true;
$.param(data); // "s=2&s=1"

// jQuery 1.3.2
$.param(data); // "s=2&s=1"
