------解决方案--------------------------------------------------------
<body onkeydown= "if(event.keyCode！=“”){reload.click()} ">
你试试看看判断它输入的不为空就触发事件
------解决方案--------------------------------------------------------
function handleEvent(oEvent)
{
alert(oEvent.type);
alert(oEvent.keyCode.toString());
alert(oEvent.charCode.toString());
}
<textare id = "txtInput " rows= "15 " clos= "50 " onkeydown= "handleEvent(event) " onkeyup= "handleEvent(event) " onkeypress= "handleEvent(event) "> </textare>
