对第一个DropDownList使用onchange事件。根据选择启用/禁用第二个DropDownList。
Use onchange event for first DropDownList. Enable/Disable second DropDownList based on the selection.
<script>
function EnableDisable()
{
var e = document.getElementById("FirstDropDownList");
var selectedText = e.options[e.selectedIndex].text;
if(selectedText == "Enable")
document.getElementById("SecondDropDownList").disabled=false;
else
document.getElementById("SecondDropDownList").disabled=true;
}
</script>
