【中文标题】创建用户向导第 2 步 javascript 没有响应【英文标题】：create user wizard step 2 javascript doesn't respond 【发布时间】：2013-06-01 02:42:24 【问题描述】：我有一个 asp.net 4.5 创建用户表单，其中前两个步骤使用 TemplatedWizardStep 进行布局。 在第 2 步中，我有一些应该对单选按钮单击操作做出反应的 javascript。 我最初在步骤 1 中有无线电操作，并且 javascript 按预期工作。 由于我将其移至第 2 步，因此它不再起作用。 我去了萤火虫并在脚本上设置了一个监视，但脚本在第 2 步中不可用。在页面源视图中，没有包含第 2 步的控件，只有第 1 步中的控件。当我检查时，我在第 2 步页面源视图。 有谁知道如何按预期进行这项工作？
谢谢

<script type="text/javascript">
function radio(cnt)
var radioButtons = document.getElementById("ContentPlaceHolder1_RegisterUser_ctl05_RadioButtonList1");
var inputs = radioButtons.getElementsByTagName("input");
var li = document.getElementById("liSearch");
var liResults = document.getElementById("liResults");
var liSelf = document.getElementById("liSelf");
if (inputs[1].checked)
li.style.display = "none";
liResults.style.display = "none";
liSelf.style.display = "none";
else
li.style.display = "block";
liResults.style.display = "block";
liSelf.style.display = "block";
</script>
【问题讨论】：
【参考方案1】：我想你手动设置了 id
ContentPlaceHolder1_RegisterUser_ctl05_RadioButtonList1
当您将其移至第 2 步时，该 ID 会发生变化。
改为动态获取id为：
var radioButtons = document.getElementById("<%=RadioButtonList1.ClientID%>");
它会起作用的。
【讨论】：
谢谢。名字确实变了。我将设置客户端 ID。 @SheriTrager 您收到一个错误，因为您在向导和更新面板中都有它。因此，如果使用 Find Control，可以找到 RadioButton id - 这是怎么回事。以上是关于创建用户向导第 2 步 javascript 没有响应的主要内容，如果未能解决你的问题，请参考以下文章
