下拉列表onchange事件和AJAX的MVC [英] DropDown list onchange event and AJAX in MVC

问题描述

我有我的MVC视图中的code黑色如下：

I have a code black in my MVC view as follows:

<%using (Ajax.BeginForm("MyAction", new { action = "MyAction", controller = "Home", id = ViewData["selected"].ToString() }, new AjaxOptions { UpdateTargetId = "Div1" }))
     { %>
          <%=Html.DropDownList("ddl", ViewData["MyList"] as SelectList, new { onchange = "this.form.submit()" })%>
                 <%} %>

我想设置ViewData的价值[选择]，这样我可以把它送到所需的操作。 任何人都可以请建议我怎么能做到这一点？

I want to set the value of ViewData["selected"] so that i can send it to the desired action. Can anyone please suggest how can i do this?

谢谢！

推荐答案

，为什么不上你的下拉使用jQuery的onChange事件？

Instead of using a form, why not use a jQuery onChange event on your drop down?

$(document).ready(function() {
    $("#ddl").change(function() {
        var strSelected = "";
        $("#ddl option:selected").each(function() {
            strSelected += $(this)[0].value;
        });
        var url = "/Home/MyAction/" + strSelected;

        $.post(url, function(data) {
            // do something if necessary
        });
    });
});
