function update() { var container = document.getElementById("ItemContainer"); container.innerHTML = ""; for(var i=0;i<this.bookMarkList.length;i++){ var name = this.ItemContainer[i].name; var tr = document.createElement('tr'); var td = document.createElement('td'); tr.appendChild(td); tr.onclick = function(){add(name);}; container.appendChild(tr); } }绑定相同函数，但是每个tr传的参数不同，应该怎样写呢。现在这样写每个tr都被绑定最新赋值的参数。
