如何在表单提交上编写javascript警报 [英] how to write javascript alert on form submit

问题描述

Hello Experts，



这是我的Aspx页面

Hello Experts,

Here is my Aspx page

<form id="FindItems" method="post" action="">
      <input type="hidden" id="FormAction" name="FormAction" value="" />
      <input type="hidden" name="SearchValue" value="<asp:Literal ID='litSearchValue' runat="'server'" />" </form>
       Department:
      <select name="Dept">
<asp:Literal ID="litDeptOptions" runat="server" />
      </select>
     Product Code:

       <input type="text" name="txtVpPrdCd" maxlength="15" style="text-transform:uppercase;"/>

      <input type="submit" value="Search" onclick="myFunction()" />

现在我希望用户点击提交时运行JavaScript。说用户只能输入部门或产品代码，但不能同时输入两者？我怎么能这样做...

请帮帮我这个

Now I want a JavaScript to run when user clicks on submit . saying that user is allowed to enter only either Department or Product Code but not both? How can I do that...
Please help me in this

推荐答案

检查这个解决方案....我点了一下按钮函数并在下拉列表中添加一个id。

Check this solution.... I took a button click function and add an id to the Drop Down List.

（ ＃btnSelect）。click（ function （）{
var ddl =

( "#btnSelect" ).click(function() { var ddl =

（ ＃id1选项：选择）。val（）;
// alert（ddl ）;

var text =

("#id1 option:selected").val(); //alert(ddl); var text =
