jquery implements sorting according to Chinese tables
This time I will bring you jquery to sort according to Chinese tables. What are the precautions for jquery to sort according to Chinese tables? The following is a practical case, let's take a look.
//转换器，将列的字段类型转换为可以排序的类型：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();
}
}
// 汉字排序方法
function chrComp(a,b)
{
return a.localeCompare(b);
}
//排序函数产生器
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;
}
}
}
};
}

}
}
/*排序方法（主函数）iCol represents the column index
1, when it is not an input type, iCol represents the td of tr;
2, when it is an input type , then iCol represents the input number in this tr;
sDataType represents the
data type of the cell or the data type of the value of the input. The default is string, but 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 direct reverse order when sorting after the input value changes.
*/
function sortTable(sTableID, iCol, sDataType, isinput, sDec)
{

};Originally, this plug-in has jquery.tablesorter.pack.js which is only 9kb after compression, but I will only change jquery.tablesorter.js (23kb). I don't know how to turn it into jquery.tablesorter.pack.js.
ps: Of course, this plug-in also has many extended functions, such as multi-column sorting, various examples, etc. There are documents for reference.
