求高人指导，jquery控制控件的禁用和启用状态
<script type= "text/javascript ">
function updae(onde) {
$( "#btnSubmit ").attr( "disabled ", "false ");
}
</script>
<input id= "e_name " onblur= "return updae(this); " runat= "server " onkeyup= "return updae(this); "/>
<asp:Button ID= "btnSubmit " runat= "server " Text= " " CssClass= "btnSubmit " Enabled= "false " onclick= "btnSubmit_Click " />
我想在光标离开文本框和键盘事件里把Button设为启用，jq应该怎么写呢？
