我是靠谱客的博主孝顺酒窝，最近开发中收集的这篇文章主要介绍拖拉表格的JS函数，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

JS：

复制代码代码如下:

/* 
@parem object the tbody's object 
@parem object tr's object (must be null) 
@parem string the className of onmousedown 
@parem string the className of onmouseout 
*/ 
function order(tt,old,classover,classout) { 
var sf = arguments.callee; //get the function self 
var trs = tt.getElementsByTagName('tr'); 
for(var i=0;i<trs.length;i++) { 
trs[i].onmousedown = function () { 
if(this.style.cursor == 'move') { 
return false; 
} 
classout = this.className; 
this.className = classover; 
this.style.cursor = 'move'; 
old = this; 
} 
trs[i].onmouseover = function () { 
if(this.style.cursor == 'move' || !old) { 
return false; 
} 
var tmp_old = old.cloneNode(true); 
var tmp_now = this.cloneNode(true); 
var p = this.parentNode; 
p.replaceChild(tmp_now,old); 
p.replaceChild(tmp_old,this); 
sf(tt,tmp_old,classover,classout); 
} 
trs[i].onmouseout = function () { 
//this.className = classout; 
} 
trs[i].onmouseup = function () { 
this.className = classout; 
this.style.cursor = ''; 
old = null; 
} 
} 
}
