1.比较函数生成器：
复制代码 代码如下:
function generateCompareTRs(iCol, sDataType) {
return function compareTRs(oTR1, oTR2) {
vValue1 = convert(oTR1.cells[iCol].firstChild.nodevalue, sDataType);
vValue2 = convert(oTR2.cells[iCol].firstChild.nodevalue, sDataType);
if (vValue1 < vValue2) {
return -1;
} else if (vValue1 > vValue2) {
return 1;
} else {
return 0;
}
};
}
2.处理比较字符类型：
复制代码 代码如下:
function convert(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();
}
}
3.主函数：
复制代码 代码如下:
function sortTable(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(generateCompareTRs(iCol, sDataType));
}
var oFragment = document.createdocumentFragment();
for ( var j = 0; j < aTRs.length; j++) {
oFragment.appendChild(aTRs[j]);
}
oTBody.appendChild(oFragment);
oTable.sortCol = iCol;
}
将以上问代码封装到一个js文件中，在html页面中引用。
测试test.html:
复制代码 代码如下:
< html xmlns = "http://www.w3.org/1999/xhtml" >
< title > 表列排序
< script type = "text/javascript" src = "js/sortTable.js" >
< body >
< table border = "1" id = "tblSort" >
< thead style = "color: red; bgcolor: blank" >
< tr >
< th onclick = " sortTable('tblSort',0);" style = "cursor: pointer" > LastName
< th onclick = " sortTable('tblSort',1,'int');" style = "cursor: pointer" > Number
< th onclick = " sortTable('tblSort',2,'date');" style = "cursor: pointer" > Date
< tbody >
< tr >
