js的table排序,支持多浏览器,多列同时排序,自定义排序

简单且轻松自定义排序规则:

1.initSortTable(asc,desc);是初始化排序预操作(其实就是传入两张图片地址,标识排序方向的)

2.在需要排序的表格table上添加监听事件,sortColumn();此处被我限定click事件作用在th对象上才有效的。

3.需要按列制定排序规则,即在th上添加type类型,例如<th type='string'>1</th>; 如果想要二重排序的话写成<th type='string,0'>1</th>,0标识列号,即本列排序时如果排序内容相同,则按照第零列排序。

4.这里的排序规则可以自由定义,当然目前的代码中只是传入了td单元格内容innerText值,也就是显示的文字。(不过你也可以修改下,传入一个对象)

可能文字描述不直观,附上一个例子吧:

<html>	
	<head>
		<title>sorttest</title>
		<script type="text/javascript" src="javascript/table-sort.js"></script>
	</head>
	<script >
		function init(){
			initSortTable("images/tablesorter/desc.gif","images/tablesorter/asc.gif");
		}
	</script>
	<body onload='init();'>
		<table onclick="sortColumn(event)">
			<thead>
				<tr>
					<th NOWRAP type="Number">ID</th>
					<th NOWRAP type="myDate,0">Date</th>
					<th NOWRAP type="str,0">Org</th>
					<th NOWRAP type="str,0">Dest</th>
					<th NOWRAP type="bool,0">Flip</th>
					<th NOWRAP type="ip,0">IP</th>
				</tr>
			</thead>
			<tbody>
				<tr>
					<td NOWRAP><%=id %></td>
					<td nowrap><%=date %></td>
					<td NOWRAP><%=org %></td>
					<td NOWRAP><%=dest %></td>
					<td NOWRAP><%=flip %></td>
					<td NOWRAP><%=ip %></td>
				</tr>
			</tbody>
		<table>
	</body>
</html>

具体代码如下,里面包含了一下我自定义处理,比较撮。

var dom = (document.getElementsByTagName) ? true : false;
    var ie5 = (document.getElementsByTagName && document.all) ? true : false;
    var arrowUp, arrowDown;
    var mydefinedChar = "*";
    
//if (ie5 || dom)
    //initSortTable();
    function initSortTable(asc,desc) {   
        arrowUp = document.createElement("SPAN"); 
        arrowUp.style.display = "inline";
        var img = document.createElement("Img");
        img.src = asc;
        arrowUp.appendChild(img);
        arrowUp.className = "arrow";
        arrowDown = document.createElement("SPAN");
        arrowDown.style.display = "inline";
        img = document.createElement("Img");
        img.src = desc;
        arrowDown.appendChild(img);
        arrowDown.className = "arrow";
    }   
    function sortTable(tableNode, nCol, bDesc, sType) {   
        var tBody = tableNode.tBodies[0];
        var trs = tBody.rows;
        var trl= trs.length;
        var a = new Array();
        for (var i = 0; i < trl; i++) {   
            a[i] = trs[i];
        }   
        var start = new Date;
        window.status = "Sorting data...";
        a.sort(compareByColumn(nCol,bDesc,sType));
        window.status = "Sorting data done";
        for (var i = 0; i < trl; i++) {   
            tBody.appendChild(a[i]);
            window.status = "Updating row " + (i + 1) + " of " + trl +   
                " (Time spent: " + (new Date - start) + "ms)";
        }   
        // check for onsort   
        if (typeof tableNode.onsort == "string")   
            tableNode.onsort = new Function("", tableNode.onsort);
        if (typeof tableNode.onsort == "function")   
            tableNode.onsort();
    }   
    function CaseInsensitiveString(s) {   
        return String(s).toUpperCase();
    }   
    function parseDate(s) {   
        return Date.parse(s.replace(/\-/g, '/'));
    }   
    function toNumber(s) {   
        return Number(s.replace(/[^0-9\.]/g, ""));
    }   
    function Percent(s) {   
        return Number(s.replace("%", ""));
    }   
    function dostr(s){
    	return String(s).toUpperCase();
    }
    function donum(val){
		var s1 = "";
