How do you submit a dropdownlist in asp.net mvc
提问by maxnk
<% using (Html.BeginForm() { %>
<%=Html.DropDownList("TopItemsList", ViewData["ListData"], new { onchange="[???]" })%>
<% } %>
In the above example, what value should you set onchange to? Or, how do you get the correct form?
在上面的例子中,你应该将 onchange 设置为什么值?或者,您如何获得正确的表格?
Is there any difference with Ajax.BeginFrom?
与 Ajax.BeginFrom 有什么区别吗?
回答by maxnk
try this:
尝试这个:
<%=Html.DropDownList("TopItemsList", ViewData["ListData"], new { onchange="this.form.submit();" })%>
Every form element in the has a "form" property that is pointed to the form that contains this element.
中的每个表单元素都有一个指向包含该元素的表单的“表单”属性。
Yes, using "Html." and "Ajax." has a difference. Ajax. means that partial page update will be used and the whole page will not be reloaded.
是的,使用“HTML”。和“阿贾克斯”。有区别。阿贾克斯。意味着将使用部分页面更新并且不会重新加载整个页面。

Delete the onchange attribute and add some JQuery:
删除 onchange 属性并添加一些 JQuery:
$("#TopItemsList").change(function () {
$("input[type=submit]").click();
});
