下面这个能赋值
$(document).ready(function () {
$('#add_purchaseOrderDetailList_table tr').each(function () {
alert($(this).children('td').eq(0).html()); //td 第0列
var url = $(this).children('td').eq(0).html()
var name = $(this).children('td').eq(1).html() //td 第1列
$("#bootImg").attr("src",$(this).children('td').eq(0).html());
$("#bootImg").attr("alt",name);
$("#bootImg").attr("title",name);
});
});
