JS如下：
TableUtil.Convert = function(sValue,sDataType)
{
switch(sDataType)
{
case "int":
return parseInt(sValue);
case "float":
return parseFloat(sValue);
case "date":
return new Date(Date.parse(sValue));
default:
return sValue.toString();
}
}
TableUtil.generateCompareTypeTRs = function(iCol,sDataType)
{
return function compareTypeTRs(oTR1,oTR2)
{
var vValue1 = TableUtil.Convert(oTR1.cells[iCol].firstChild.nodeValue,sDataType);
var vValue2 = TableUtil.Convert(oTR2.cells[iCol].firstChild.nodeValue,sDataType);
if(vValue1<vValue2)
{
return -1;
}
else if(vValue1>vValue2)
{
return 1;
}
else
{
return 0;
}
}
}
TableUtil.sortTypeTable = function(sTableId,iCol,sDataType)
{
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.generateCompareTypeTRs(iCol,sDataType));
}
var oFragment = document.createDocumentFragment();
for(var i = 0;i <aTRs.length;i++)
{
oFragment.appendChild(aTRs[i]);
}
oTbody.appendChild(oFragment);
oTable.sortCol = iCol;
}
