如何通过ajax将集合/数组发送到mvc动作

Question

atm我正在尝试这样,但没有运气,我的Do行动无效

var arr = [31,17,16];

$.get('<%=Url.Action("Do", "Foo") %>', 
       {ids:arr},
       function(d){...});

public ActionResult Do(IEnumerable<int> ids)
{
...
}

Answer 1

试试这样:

$.ajax({
    url: '<%= Url.Action("Do", "Foo") %>',
    data: { ids: [ 31, 17, 16] },
    traditional: true,
    success: function(result) {

    }
});

注意traditional: true参数.

或者如果你坚持这个$.get()功能:

$.get(
    '<%= Url.Action("Do", "Foo") %>', 
    $.param({ ids: [31, 17, 16] }, true), 
    function (result) {

    }
);
