如何重置html中选定的索引下拉列表值？ [英] How to reset the selected index dropdown value in html?

问题描述

我需要在提交表单后为selecteddown设置selectedindex = 0。
我试过如下。

I need to set the selectedindex=0 for dropdown after submit form. I tried like the below.

 $("#filterByName").prop('selectedIndex', 0);
 $("#filterByName").selectedIndex=0;
$("#filterByName").get(0).selectedindex=0;

但我无法实现。请告诉我如何在提交表格后重置下拉列表。

but i am not able to acheive .please tell me how to reset the dropdown after submit form.

编辑：
$（'＃filterByName'）[0] .selectedIndex .in我正在选择索引值。在sumit点击我设置$（ '#filterByName'）[0] .selectedIndex = 0然后这个语句没有设置在点击event.assigning之后显示索引0但是为什么在UI中没有显示？

$('#filterByName')[0].selectedIndex .in that i am getting selected index value.after sumit click i am setting $('#filterByName')[0].selectedIndex=0 then this statement not setting showing the index 0 after click event.assigning but why in UI is not showing ?

<span id="filterByNames"><%= Html.DropDownList("filterByName", new SelectList(Model.Names, "Name", "Name", Model.Name), 
                                new { onchange = "filterByName()" }) %></span>
