如何为TextBox设置TextChange事件？！ [英] how to set TextChange Event For TextBox?!

问题描述

嗨所有

i有一个我想按一个键的文本框，一个服务器函数调用!!!



我添加OnTextChanged =TextBoxChang但它不能正常工作!!!

当TextBoxChang调用第一个Focuse然后然后模糊然后检查文本是否正在改变时！



i希望用户按A键服务器功能调用!!!

非常感谢





失败不是一个选项

< asp：TextBox ID =TextBoxCaptionClientIDMode =Staticrunat =serverOnTextChanged =TextBoxCaption_TextChanged> 

服务器端：

 protected void TextBoxCaption_TextChanged（object sender，EventArgs e） 
 {
 //当我按下每个键时不动作
} 

解决方案

尝试设置AutoPostBack = true。

你必须使用jquery，以下是示例

< script type =text / javascript>

Failure Is Not An Option

<asp:TextBox ID="TextBoxCaption"  ClientIDMode="Static" runat="server" OnTextChanged="TextBoxCaption_TextChanged">

in server Side:

 protected void TextBoxCaption_TextChanged(object sender, EventArgs e)
    {
//Not Act When i Press Every Key
    }

解决方案

Try setting the AutoPostBack = true.

You have to use jquery for that, bellow is the example
<script type="text/javascript">
