Code: I copied the code written by a netizen. I don’t remember where it came from. It was changed to support Chinese sorting and the sorting of control values. There is no way, my ability is limited, I can only do it. . .
//Converter, convert the field type of the column to Types that can be sorted: String, int, float
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();
}
}
// Chinese character sorting method
function chrComp(a,b)
{
return a.localeCompare(b);
}
//Sorting function generator
function generateCompareTRs(iCol, sDataType,isinput,sDec)
{
return function compareTRs(oTR1, oTR2)
{
if(isinput == 1)
{
var vValue1 = convert(oTR1.getElementsByTagName("input")[iCol].value);
var vValue2 = convert(oTR2.getElementsByTagName("input")[iCol] .value);
}
else
{
var vValue1 = convert(oTR1.cells[iCol].firstChild.nodeValue, sDataType);
var vValue2 = convert(oTR2.cells[ iCol].firstChild.nodeValue, sDataType);
}
if(sDec=='desc')
{
if(sDataType=='int')
{
return vValue1 == vValue2 ? 0 :(vValue1 - vValue2 <0 ? 1 : -1);
}
else if(sDataType =='cn')
{
if(chrComp(vValue1 ,vValue2)>0)
{
return -1;
}
else if(chrComp(vValue1,vValue2)<0)
{
return 1;
}
else
{
return 0;
}
}
else
{
if (vValue1 > vValue2) {
return -1;
} else if (vValue1 < vValue2) {
return 1;
} else {
return 0;
}
}
}
else if(sDec =='asc')
{
if(sDataType=='int')
{
return vValue1 == vValue2 ? 0 :(vValue1 - vValue2 >0 ? 1 : -1) ;
}
else if(sDataType =='cn')
{
return chrComp(vValue1,vValue2);
}
else
{
if ( vValue1 > vValue2) {
return 1;
} else if (vValue1 < vValue2) {
return -1;
} else {
return 0;
}
}
}
};
}
//Reset the classname of the cell

tr.childNodes[i].className = " row" num
}
}
/*Sort method (main function)
sTableID table ID
iCol represents column index
1, when it is not an input type, iCol represents It is the td of tr;
2, when it is input type, iCol indicates the input of tr;
sDataType indicates the data type of the cell or the data type of the value of the input. . The default is string, it can also be int, float. cn is Chinese
isinput indicates whether the sorted content is input (1 yes, 0 no)
sDec indicates reverse order or order (desc, default order), to avoid input After the value is changed, the order will be directly reversed when sorting.
*/
function sortTable(sTableID, iCol, sDataType, isinput, sDec)
{
var oTable = document.getElementById(sTableID);
var oTBody = oTable.tBodies[0] ;
var colDataRows = oTBody.rows;

I finally have time to study jquery this week, which I have always wanted to learn. It's a pity that the company can't use it. In fact, after learning it, I still feel that it can be used. After knowing jqery, I looked at other people's plug-ins. jquery.tablesorter.js This plug-in is quite powerful. I tried it and found that it does not support Chinese. Look at the source code and it says
/* sorting methods */
function multisort(table,sortList,cache) {
if(table.config.debug) { var sortTime = new Date(); }
var dynamicExp = "var sortWrapper = function(a,b) {", l = sortList.length;
for(var i=0; i < l; i ) {
var c = sortList[i][0];
var order = sortList[i][1];
var s = (getCachedSortType(table.config.parsers,c) == "text") ? ((order == 0) ? "sortText" : "sortTextDesc") : ((order == 0) ? "sortNumeric" : "sortNumericDesc");
var e = "e" i;
dynamicExp = "var " e " = " s "(a[" c "],b[" c "]); ";
dynamicExp = "if(" e ") { return " e "; } ";
dynamicExp = "else { ";
}
for(var i=0; i < l; i ) {
dynamicExp = "}; ";
}
dynamicExp = "return 0; ";
dynamicExp = "}; ";
eval(dynamicExp);
cache.normalized.sort(sortWrapper);
if(table.config.debug) { benchmark("Sorting on " sortList.toString() " and dir " order " time:", sortTime); }
return cache;
};
function sortText(a,b) {
return ((a < b) ? -1 : ((a > b) ? 1 : 0));
};
function sortTextDesc(a,b) {
return ((b < a) ? -1 : ((b > a) ? 1 : 0));
};
function sortNumeric(a,b) {
return a-b;
};
function sortNumericDesc(a,b) {
return b-a;
};
function getCachedSortType(parsers,i) {
return parsers[i].type;
};
一开始还以为会遇到一些困难的。没想到,我只需要把他的排序函数改一下就ok啦.
function sortText(a,b) {
return a.localeCompare(b);
};
function sortTextDesc(a,b) {
return -a.localeCompare(b);
};
测试一下。中文,中英文一起,中间有列为空等都没问题了。
本来这个插件是有一个jquery.tablesorter.pack.js 压缩过后的才9kb,可是我只会改jquery.tablesorter.js (23kb)。要怎么把它变成jquery.tablesorter.pack.js 就不知道了。
ps:当然这个插件还有很多扩展功能,例如多列排序,各种例子等都有文档可以参考的。原文件和例子网上应该挺多的。有需要的 童鞋 可以留个邮箱给我
