当表格里的数据超出时，鼠标放上去显示

CSS:#datatableID {background: none repeat scroll 0 0;margin: 0px auto;width: 100%;table-layout: fixed;border: 1px solid #a1bcdb;}#datatableID td {border: 1px solid #a1bcdb;word-break: break-all;white-space: nowrap;overflow: hidden;text-overflow: ellipsis;-o-text-overflow: ellipsis;}

jQuery:<script>jQuery(function() {$("#datatableID tr:gt(0)").each(function(i) {var td = $(this).find("td:eq(8)");//给td设置title属性,并且设置td的完整值.给title属性.td.attr("title", td.text());});});</script>
