DropDown列表onchange事件和MVC中的AJAX

Question

我的MVC视图中的代码为黑色,如下所示:

<%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 ["selected"]的值,以便我可以将其发送到所需的操作.任何人都可以建议我怎么做？

谢谢!

Answer 1

而不是使用表单,为什么不在下拉列表中使用jQuery onChange事件？

$(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
        });
    });
});
