Question

我有C#.Net MVC3网。我的提议模式有“Edit View”。关于Edit View,一份提案清单的下降名单。所需经费是,当用户变更Droop Down名单中的选用物时,选定的提案需要由提案主计长负担。我能够收到Edit View的介绍,但不知道如何 gr弄DownList博士的价值,以找到选定的建议。我相信,这非常可行。想法?

Answer 1

You could put the dropdownlist inside a form and then when the selection changes submit the form. This way the selected value will automatically be sent to the controller action. Or if you are manually doing some AJAX request when the selection changes you could send the selected value along with the request:

$( #id_of_your_ddl ).change(function() {
    var selectedProposal = $(this).val();
    $( #resultDiv ).load( @Url.Action("Index", "Proposal") , { id: selectedProposal });
});
