方法一：
JS如下：//保存为JScript1.js文件
TableUtil.generateReverseCompareTRs = function(iCol)
{
return function compareTRs(oTR1,oTR2)
{
//var flag = document.getElementById("tempFlag").value;
var sValue1 = oTR1.cells[iCol].firstChild.nodeValue;
var sValue2 = oTR2.cells[iCol].firstChild.nodeValue;
return sValue1.localeCompare(sValue2);
}
}
TableUtil.ReverseSortTable = function (sTableId,iCol)
{
var oTable = document.getElementById(sTableId);
var oTbody = oTable.tBodies[0];
var colDataRows = oTbody.rows;
var aTRs = new Array;
for(var i =0;i <colDataRows.length;i++)
{
aTRs[i]=colDataRows[i];
}
if(oTable.sortCol == iCol)
{
aTRs.reverse();
}
else
{
aTRs.sort(TableUtil.generateReverseCompareTRs(iCol));
}
var oFragment = document.createDocumentFragment();
for(var i = 0;i <aTRs.length;i++)
{
oFragment.appendChild(aTRs[i]);
}
oTbody.appendChild(oFragment);
oTable.sortCol = iCol;
}

方法二：
JS如下:
var TableUtil = new Object();
TableUtil.generateCompareTRs = function(iCol,flag)
{
return function compareTRs(oTR1,oTR2)
{
var sValue1 = oTR1.cells[iCol].firstChild.nodeValue;
var sValue2 = oTR2.cells[iCol].firstChild.nodeValue;
if(flag==0)
{
return sValue1.localeCompare(sValue2);
}
if(flag ==1)
{
return -sValue1.localeCompare(sValue2);
}
}
}
TableUtil.sortMultiColTable = function(sTableId,iCol)
{
var oTable = document.getElementById(sTableId);
var oTbody = oTable.tBodies[0];
var colDataRows = oTbody.rows;
var aTRs = new Array;
for(var i = 0; i <colDataRows.length; i++)
{
aTRs[i]=colDataRows[i];
}
var flag = document.getElementById("tempFlag").value ;
aTRs.sort(TableUtil.generateCompareTRs(iCol,flag));
var oFragment = document.createDocumentFragment();
for(var i=0; i <aTRs.length;i++)
{
oFragment.appendChild(aTRs[i]);
}
oTbody.appendChild(oFragment);
if(flag==0)
{
flag = 1;
}
else if(flag == 1)
{
flag = 0;
}
document.getElementById("tempFlag").value = flag;
}
