答

您可以使用textBox的onkeyup事件.

示例:

< asp:textbox id ="txtObj" runat ="server" onkeyup ="changeValue(this);" />

函数changeValue(obj)
{
document.getElementByID("listboxObj").value = obj.value;
返回false;
}

希望能为您工作.

you can use onkeyup event of the textBox.

Example:

<asp:textbox id="txtObj" runat="server" onkeyup="changeValue(this);" />

function changeValue(obj)
{
document.getElementByID("listboxObj").value=obj.value;
return false;
}

hopes this work for u..
