情况一：使用href = 'javascript:del(this);' ；
function del(a){
alert(a); //结果为 [object Window]
var p=a.parentNode.parentNode;
alert(p); //词句执行失败
var t=p.parentNode;
t.removeChild(p);

}

情况二：使用onclick='javascript:del(this)' ；
function del(a){
alert(a); //结果为弹出框中显示空白
var p=a.parentNode.parentNode;
alert(p); //结果为 [object HTMLTableRowElement]
var t=p.parentNode;
t.removeChild(p);

}
[解决办法]
onclick='javascript:del(this)
是调用事件
