为什么不简单地将textbox的AutoPostBack属性设置为true,它会在每次文本更改时自动回发,从而触发textchanged事件

  <script type="text/javascript">
    function RefreshIt(selectObj) {
      __doPostBack('<%= Page.ClientID %>', selectObj.name);
    }
  </script>

</head>

  <form id="form1" runat="server">
  <div>

    <asp:TextBox runat="server" AutoPostBack="True" ID="txtG1" OnTextChanged="txtG1_TextChanged"

如果满足正常引发ontextchanged事件的条件,则iffield16 ontextchanged会正确激发。我很难让onmouseout事件同时引发强制ontextchanged事件。好的,我明白你的意思。我做了一个简单的项目并进行了一些测试。我用我的发现更新了我的答案。谢谢你的帮助。这让我朝着正确的方向前进。当满足正常引发ontextchanged事件的条件时,ontextchanged会正确激发。我很难让onmouseout事件也引发强制引发ontextchanged事件。好的,我明白你的意思。我做了一个简单的项目并做了一些测试。我用我的发现更新了我的答案。感谢h这让我朝着正确的方向前进。这不是自动回发的问题。问题是关于在asp:textbox上使用java脚本ontextchange事件。。
因为OnTextChanged不是这样工作的。控件也需要失去焦点才能触发事件。这不是自动回发的问题。问题是关于在asp:textbox上使用java脚本ontextchange事件。因为ontextchange不是这样工作的。控件还需要失去焦点才能触发事件。
