这段使控件获得焦点的代码怎么用?

Question

<script language="javascript"> 
  var control = document.getElementById(<control name>); 
  if( control != null ){ control.focus(); } 
</script> 
下面的控件是:
<asp:TextBox id="password" runat="server" TextMode="Password"></asp:TextBox><control name>这一项我始终没填对.

Answer 1

就填你的TextBox控件的id贝，就是将<control name>替换成password

Answer 2

<script language="javascript">
function setFocus(thisctrl)
{
 if( thisctrl != null )
 {
  thisctrl.focus();
 }
}
</script>
然后
<asp:TextBox id="password" runat="server" TextMode="Password"></asp:TextBox>在后台page_load里写!
password.Attributes.add("onBlur","javascript:setFocus(this)")
就可以了

Answer 3

<script language="javascript"> 
  var control = document.getElementById("password");
  if( control != null ){ control.focus(); } 
</script>

Answer 4

谢谢.刚才的代码我会用了,原来尖括号不能省
var control = document.getElementById(<password>);

Answer 5

<form runat="server">
<asp:TextBox id="password" runat="server" TextMode="Password"></asp:TextBox>
</form>
<script language="javascript"> 
document.getElementById("password").focus(); 
</script>
