问题描述

我想通过使用JavaScript或jQuery将html表格滚动到特定的tr。目前我可以获得所选tr的偏移量。而且我使用scrollTop方法。我尝试了以下方法,但它不适用于我:

  var table = document.getElementById(table); 
var tr = table.getElementsByTagName(tr)[3];
var scrollTo = tr.offsetTop;
table.scrollTop = scrollTo;

我也试过jquery:

<$ p 。$ p> $( '#表')动画({scrollTop的:0},50);

任何人都可以帮我解决问题吗?

解决方案

试试这个: http://jsfiddle.net/SZKJh/

  var w = $(window); 
var row = $('#tableid')。find('tr')。eq(line);

if(row.length){
w.scrollTop(row.offset()。top - (w.height()/ 2));
}
