我希望它在用户选择用户 ID 之后发生，然后用户 ID 显示在第一个只读文本框上，然后onChange当它显示在第一个只读文本框上时应该触发事件，以便它可以将此用户 ID 复制到第二个文本框。但是它不起作用，它仅起作用是用户ID显示在第一个文本框上，但 onChange 不会触发第二个文本框。

这里有一半的工作代码：

<tr>
    <td align="right">
        Secondary Owner
    </td>
    <td>
        <input id="Hidden1" type="hidden" />
        <asp:TextBox ID="tbAdd_Sowner" runat="server" Enabled="false"></asp:TextBox>
        <input id="Hidden2" type="hidden" />
        <input id="Hidden3" type="hidden" />
        <a href="javascript:void(0)" onclick="GalModalTOCCDialog(Hidden1, tbAdd_Sowner, Hidden2,Hidden3)">
            Get User ID</a>
        <asp:RequiredFieldValidator ID="RequiredFieldValidator7" ValidationGroup="g1" runat="server" ErrorMessage="* Required" ControlToValidate="tbAdd_Sowner"> <b style="color:Red;"> * </b></asp:RequiredFieldValidator>
        <asp:ValidatorCalloutExtender ID="ValidatorCalloutExtender8" runat="server" TargetControlID="RequiredFieldValidator7">
        </asp:ValidatorCalloutExtender>
    </td>
</tr>
<tr>
    <td align="right">Secondary Owners</td>
    <td>
        <asp:TextBox ID="tbAdd_Sphone" runat="server"></asp:TextBox>
        <asp:RequiredFieldValidator ID="RequiredFieldValidator13" ValidationGroup="g1" runat="server" ErrorMessage="* Required" ControlToValidate="tbAdd_Sphone"> <b style="color:Red;"> * </b></asp:RequiredFieldValidator>
        <asp:ValidatorCalloutExtender ID="ValidatorCalloutExtender9" runat="server" TargetControlID="RequiredFieldValidator13">
        </asp:ValidatorCalloutExtender>
    </td>
</tr>

然后一个javascript代码<head>复制第一个文本框值并放入第二个文本框：

 <script>
        function getUserID() {
            document.getElementById('tbAdd_Sphone').value = document.getElementById('tbAdd_Sowner').value;
        }

document.getElementById('tbAdd_Sowner').onchange = getUserID();

            </script>

您不能仅通过从 javascript 设置值来进行更改事件。这是使用触发器的示例。

 <script>
       $(document).ready(function () {

           $(".tbAdd_Sowner").on('change', function () {
               var owner = $('.tbAdd_Sowner').val();
               $('.tbAdd_Sphone').val(owner);
           });

           $(".aGetID").on('click', function () {
               var tbOwner = $('.tbAdd_Sowner');
               var hidden1 = $('.Hidden1');
               var hidden2 = $('.Hidden2');
               var hidden3 = $('.Hidden3');
               GalModalTOCCDialog(hidden1, tbOwner, hidden2, hidden3);

           });

           function GalModalTOCCDialog(Hidden1, tbAdd_Sowner, Hidden2, Hidden3) {
               $(tbAdd_Sowner).val(' ').trigger('change');
           }

           $('.tbAdd_Sowner').change(function () {
               $(this).removeAttr('disabled');

           });
       });
    </script>

这是您的代码，删除那些验证器

<table>
        <tr>
            <td align="right">Secondary Owner
            </td>
            <td>
                <input id="Hidden1" type="hidden" value="1" class="Hidden1"  />
                <asp:TextBox ID="tbAdd_Sowner" OnTextChanged="tbAdd_Sowner_TextChanged" CssClass="tbAdd_Sowner" AutoPostBack="true" runat="server" Enabled="false"   ></asp:TextBox>
                <input id="Hidden2" type="hidden" class="Hidden2" />
                <input id="Hidden3" type="hidden" class="Hidden3" />
                <a href="javascript:void(0)" id="aGetID" class="aGetID" >Get User ID</a>

            </td>
        </tr>
        <tr>
            <td align="right">Secondary Owners</td>
            <td>
                <asp:TextBox ID="tbAdd_Sphone" runat="server" CssClass="tbAdd_Sphone" ></asp:TextBox>

            </td>
        </tr>
    </table>

服务器端。

protected void tbAdd_Sowner_TextChanged(object sender, EventArgs e)
        {
            tbAdd_Sowner.Text = "123";
        }

通过 JavaScript更改的值tbAdd_Sowner（我假设通过您的GalModalTOCCDialog函数）不会触发onchange事件。

设置值后，您可以手动触发该事件：

document.getElementById('tbAdd_Sowner').onchange();

虽然我很惊讶你没有getElementById像@IrfanTahirKheli 显示的那样遇到问题，这对你来说应该很好......所以可能缺少你的标记部分，我们需要正确地帮助你。

您需要认真考虑的其他事项是不使用内联样式，也不使用表格进行格式化。

由于您似乎对我添加的内容有疑问，这是另一种方法。onChange从您的中删除asp:TextBox并从 javascript 中完成所有操作：

 document.getElementById('tbAdd_Sowner').value = 'somevalue';
 document.getElementById('tbAdd_Sowner').onchange = getUserID();

利用

document.getElementById('<%= tbAdd_Sphone.ClientID %>')

代替

document.getElementById('tbAdd_Sphone')

MSDN Control.ClientID 属性

用这个<asp:TextBox ID="TextBox1" runat="server" onkeypress="document.getElementById('id').Value=this.value;" />

Like others have mentioned in their answers, 

  <asp:TextBox id="tbAdd_Sphone" runat="server" />

will have a server-side dynamic client-ID prefixed to the generated HTML. If you see the source code of the page (or use the developer tools) in a browser of choice, you will notice you the ID is different than what you are passing in to your method call i.e something like this:

<textarea id="ctl00_OuterASPControlID_tbADD_Sphone"></textarea>

You can keep the className static by using class="tbAdd_Sphone" if the class is dynamically prefixed too. Or, try to get element by ID on 

<%=tbAdd_Sphone.ClientID %>

You can either set the ClientID mode to static, or you can try using UniqueID.

Another thing to note, javascript has a special behavior. If you call of a method with a set number of variables passed in correctly in the call, it will only use those values in the functionality. If there is null/undefined data passed into the call, the rest of the parameters are just ignored.

functionName:function(parameter1, parameter2) { 

            //Default behavior can be overridden if parameter2 is not passed in as expected.
            if(parameter2 ==null || parameter2=='undefined') { 
                parameter2 = "Some value"; 
                    } 
}


    functionName("testPar1");               //Works but parameter2 is not passed in as expected
    functionName("testPar1", "testPar2");   //Works
    functionName("testPar1", undefined);    //Works, but parameter2 is not passed in as expected

If you need to use the id for phone, either do a substring search for getting the element by the actual ID, or use a getElementsByTag in your javascript to search for textboxes, and you can use any other property, say in plain Javascript: 

var x = document.getElementsByTag("textbox"); 
if(x!=null && x.attribute('class') == 'tbAdd_Sphone' )  { 
 var valueX = x.attribute('value'); 
}
