推荐答案

尝试一下



JavaScript

Try this



JavaScript

<script language='JavaScript' type="text/javascript">
       function getwords() {


               document.getElementById('TextBox2').value = document.getElementById('TextBox1').value;

       }
   </script>

HTML(aspx)

Html (aspx)

<asp:TextBox ID="TextBox1" runat="server" ></asp:TextBox>
        <asp:TextBox ID="TextBox2" runat="server"></asp:TextBox>
        <asp:Button ID="Button1" runat="server" Text="Button" onclick="Button1_Click" />

背后的代码(aspx.cs)

Code behind (aspx.cs)

protected void Page_Load(object sender, EventArgs e)

{
TextBox1.Attributes.Add("Onblur"，"getwords()");
}

{
TextBox1.Attributes.Add("Onblur", "getwords()");
}

protected void Button1_Click(object sender, EventArgs e)
      {
          string test = TextBox2.Text;
      }

尝试一下，
1.双击文本框
2.set autopostback ="true"

例如:

sample.aspx
< asp:textbox id ="TextBox1" runat ="server" ontextchanged ="TextBox1_TextChanged" autopostback ="true" xmlns:asp =#unknown">


sample.aspx.cs

try this,
1.double click textbox
2.set autopostback="true"

example:

sample.aspx
<asp:textbox id="TextBox1" runat="server" ontextchanged="TextBox1_TextChanged" autopostback="true" xmlns:asp="#unknown">


sample.aspx.cs

protected void TextBox1_TextChanged(object sender, EventArgs e)
        {
//to pass the value of a control to another control
session["textboxvalue"]=TextBox1.Text;

        }

尝试一下

<pre lang="Javascript">
<script language="'JavaScript'">
function getwords(){
myOutput=document.getElementById('output');
textbox = document.getElementById('c_id');
if (textbox.value != "")
document.getElementById('output').value = textbox.value;
else
alert('<?php echo "No word has been entered!";?>')
}
</script>
