asp mvc: how to pass parameter to controller using jquery api?

I am following the following tutorial (http://www.highoncoding.com/Articles/642_Creating_a_Stock_Widget_in_ASP_NET_MVC_Application.aspx) on using ajax to render a partial form , but in this example parameters are not passed, and I have not been able to work out how to do it...

This code works with no parameter

function GetDetails() {
$("#divDetails").load('Details'); 
}

This is my attempt to a开发者_StackOverflow社区dd a parameter, but does not work (cant find action)

function GetDetails() {
$("#divDetails").load('Details?Id=20'); 
}

Paramters in MVC are added like this:

http://mysite.com/action/parameter

Change your question mark to a forward slash, and make sure your path is referenced correctly from your jquery code. You can use Firebug in Firefox or Fiddler in IE to look at the GET operation to make sure the URL for the request is properly formed.

The jQuery.load() method can take an object and will turn the request into a POST and ASP.NET MVC should do the rest.

So it should work if you try this:

function GetDetails() {
    $("#divDetails").load('Details', {Id: 20}); 
}

Ps. The default route should beable to handle Controller/Action/Id, so you should beable to do something like $("#divDetails").load('Controller/Details/20');
