A practical JavaScript class library that implements table ordering _js Object-oriented

A JavaScript class library for table content sorting. It's easy to use and you don't have to call the database every time.
Especially suitable for the sorting of multiple table queries. Plus the <tbody> style.display switch, you can also achieve pagination.
Effect Demo
Usage:
1. Add JS
<script src= "Sorttable.js" type= "Text/javascript" ></SCRIPT>
2. Add table, Note: Must have id,class for "sortable"
<table class= "sortable" id= "MyTable" >
OK, that's it, easy.
If you feel too monotonous, add your own CSS, the official gave the head to change the CSS

/* Sortable tables *
Table.sortable A.sortheader {
Background-color: #eee;
Color: #666666;
Font-weight:bold;
Text-decoration:none;
Display:block;
}
Table.sortable Span.sortarrow {
Color:black;
Text-decoration:none;
}

Copy Code code as follows:

addevent (window, "load", sortables_init);

var Sort_column_index;

function Sortables_init () {
Find all tables with class sortable and make them sortable
if (!document.getelementsbytagname) return;
TBLs = document.getElementsByTagName ("table");
for (ti=0;ti<tbls.length;ti++) {
THISTBL = Tbls[ti];
if ((' +thistbl.classname+ '). IndexOf ("sortable")!=-1) && (thistbl.id)) {
Inittable (thistbl.id);
Ts_makesortable (THISTBL);
}
}
}

function ts_makesortable (table) {
if (table.rows && table.rows.length > 0) {
var firstrow = table.rows[0];
}
if (!firstrow) return;

We have a row:assume it's header, and make its contents clickable links
for (Var i=0;i<firstrow.cells.length;i++) {
var cell = Firstrow.cells[i];
var txt = ts_getinnertext (cell);
cell.innerhtml = ' <a href= ' # ' class= ' Sortheader ' +
' onclick= ' ts_resorttable (this, ' +i+ '); > ' +
txt+ ' <span class= ' sortarrow ' > </span></a> ';
}
}

function Ts_getinnertext (EL) {
if (typeof el = = "string") return el;
if (typeof el = = "undefined") {return el};
if (El.innertext) return el.innertext; Not needed but it is faster
var str = "";

var cs = El.childnodes;
var L = cs.length;
for (var i = 0; i < L; i++) {
Switch (cs[i].nodetype) {
Case 1://element_node
str = Ts_getinnertext (cs[i]);
Break
Case 3://text_node
str = Cs[i].nodevalue;
Break
}
}
return str;
}

function Ts_resorttable (lnk,clid) {
Get the span
var span;
for (Var ci=0;ci<lnk.childnodes.length;ci++) {
if (Lnk.childnodes[ci].tagname && lnk.childnodes[ci].tagname.tolowercase () = = ' span ') span = Lnk.childnodes[ci ];
}
var spantext = Ts_getinnertext (span);
var td = Lnk.parentnode;
var column = Clid | | Td.cellindex;
var table = GetParent (TD, ' Table ');

Work out a type for the column
if (table.rows.length <= 1) return;
var itm = Ts_getinnertext (Table.rows[1].cells[column]);
SORTFN = ts_sort_caseinsensitive;
if (Itm.match (/^\d\d[\/-]\d\d[\/-]\d\d\d\d$/)) sortfn = Ts_sort_date;
if (Itm.match (/^\d\d[\/-]\d\d[\/-]\d\d$/)) sortfn = Ts_sort_date;
if (Itm.match (/^[?) /)) sortfn = ts_sort_currency;
if (Itm.match (/^[\d\.) +$/)) sortfn = Ts_sort_numeric;
Sort_column_index = COLUMN;
var firstrow = new Array ();
var newrows = new Array ();
for (i=0;i<table.rows[0].length;i++) {firstrow[i] = table.rows[0][i];}
for (j=1;j<table.rows.length;j++) {newrows[j-1] = table.rows[j];}

Newrows.sort (SORTFN);

if (Span.getattribute ("sortdir") = = ' down ') {
ARROW = ' ↑ ';
Newrows.reverse ();
Span.setattribute (' Sortdir ', ' up ');
} else {
ARROW = ' ↓ ';
Span.setattribute (' Sortdir ', ' down ');
}

We appendchild rows that already exist to the tbody, so it moves them rather than creating new ones
Don ' t do sortbottom rows
for (i=0;i<newrows.length;i++) {if (!newrows[i].classname | | (Newrows[i].classname && (newrows[i].classname.indexof (' sortbottom ') = = 1))) Table.tbodies[0].appendchild (Newrows[i]);
Do sortbottom rows
for (i=0;i<newrows.length;i++) {if (Newrows[i].classname && newrows[i].classname.indexof (' Sortbottom ')! =-1)) Table.tbodies[0].appendchild (Newrows[i]);

Delete any other arrows there may showing
var Allspans = document.getElementsByTagName ("span");
for (Var ci=0;ci<allspans.length;ci++) {
if (Allspans[ci].classname = = ' Sortarrow ') {
if (GetParent (Allspans[ci], "table") = = GetParent (lnk, "table")) {//In the same table as us?
allspans[ci].innerhtml = ';
}
}
}

span.innerhtml = ARROW;
}

function GetParent (el, Ptagname) {
if (el = = null) return null;
else if (El.nodetype = = 1 && el.tagName.toLowerCase () = = Ptagname.tolowercase ())//Gecko bug, supposed to is U Ppercase
Return el;
Else
Return GetParent (El.parentnode, ptagname);
