Sortable tables

[QBass]

I added function to sort tables in webconsole:
file: sorttable.js (found long ago, don't know author)

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 first row: assume it's the header, and make its contents clickable links
    for (var i=0;i<firstRow.cells.length;i++) {
        var cell = firstRow.cells;
        var txt = ts_getInnerText(cell);
        cell.innerHTML = '<a href="#" class="sortheader" '+ 
        'onclick="ts_resortTable(this, '+i+');return false;">' + 
        txt+'<span class="sortarrow">&nbsp;&nbsp;&nbsp;</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.nodeType) {
			case 1: //ELEMENT_NODE
				str += ts_getInnerText(cs);
				break;
			case 3:	//TEXT_NODE
				str += cs.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(/^[Ł$]/)) sortfn = ts_sort_currency;
    if (itm.match(/^[\d\.]+$/)) 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 = table.rows[0]; }
    for (j=1;j<table.rows.length;j++) { newRows[j-1] = table.rows; }

    newRows.sort(sortfn);

    if (span.getAttribute("sortdir") == 'down') {
        ARROW = '&nbsp;&nbsp;&uarr;';
        newRows.reverse();

    } else {
        ARROW = '&nbsp;&nbsp;&darr;';
        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.className || (newRows.className && (newRows.className.indexOf('sortbottom') == -1))) table.tBodies[0].appendChild(newRows);}
    // do sortbottom rows only
    for (i=0;i<newRows.length;i++) { if (newRows.className && (newRows.className.indexOf('sortbottom') != -1)) table.tBodies[0].appendChild(newRows);}
    
    // Delete any other arrows there may be 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 = '&nbsp;&nbsp;&nbsp;';
            }
        }
    }
        
    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 be uppercase
		return el;
	else
		return getParent(el.parentNode, pTagName);
}
function ts_sort_date(a,b) {
    // y2k notes: two digit years less than 50 are treated as 20XX, greater than 50 are treated as 19XX
    aa = ts_getInnerText(a.cells[SORT_COLUMN_INDEX]);
    bb = ts_getInnerText(b.cells[SORT_COLUMN_INDEX]);
    if (aa.length == 10) {
        dt1 = aa.substr(6,4)+aa.substr(3,2)+aa.substr(0,2);
    } else {
        yr = aa.substr(6,2);
        if (parseInt(yr) < 50) { yr = '20'+yr; } else { yr = '19'+yr; }
        dt1 = yr+aa.substr(3,2)+aa.substr(0,2);
    }
    if (bb.length == 10) {
        dt2 = bb.substr(6,4)+bb.substr(3,2)+bb.substr(0,2);

    }
    if (dt1==dt2) return 0;

    bb = ts_getInnerText(b.cells[SORT_COLUMN_INDEX]).replace(/[^0-9.]/g,'');

    if (isNaN(aa)) aa = 0;
    bb = parseFloat(ts_getInnerText(b.cells[SORT_COLUMN_INDEX]));

    return aa-bb;
}

function ts_sort_caseinsensitive(a,b) {

}


function addEvent(elm, evType, fn, useCapture)
// addEvent and removeEvent
// cross-browser event handling for IE5+,  NS6 and Mozilla
// By Scott Andrew
{
  if (elm.addEventListener){
    elm.addEventListener(evType, fn, useCapture);
    return true;
  } else if (elm.attachEvent){
    var r = elm.attachEvent("on"+evType, fn);
    return r;
  } else {
    alert("Handler could not be removed");
  }
} 

then adding

<script src="sorttable.js"></script>

in document (for example Computers.aspx)
and adding

class="sortable"

to

<td bgcolor="#FFFFFF"><table width="100%"  border="0" cellpadding="1" cellspacing="1" id="Resulttable">

gives abbility to sort computers list by lastseen for example.
Best regards

Bulwinkle, you are almost there. You will need some minor adjustments to get it working. You will want to remove the <script src="sorttable.js"></script> line and insert <script src="_mmServerScripts/sorttable.js"></script> into a new line in the <head> section.

I need some help with this:

created file sorttable.js then put it in the C:\LanSweeper\Webconsole\_mmServerScripts folder and then added the rest of your post to the computers.aspx file.

The bold blue are the changes I made to the file. Did I put somthing in the wrong place and should I be able to sort the webpage by the domain or last seen by clicking on the heading?

Thanks for the response:)
