自定义可排序表格
首先，定义一个js：
tableSort.js:
function sort(tableId, sortColumn,nodeType) {
var table = document.getElementById("theTable");
var tableBody = table.tBodies[0];
var tableRows = tableBody.rows;
var rowArray = new Array();
for (var i = 0; i < tableRows.length; i++) {
rowArray[i] = tableRows[i];
}
if (table.sortColumn == sortColumn) {
rowArray.reverse();
} else {
rowArray.sort(generateCompareTR(sortColumn, nodeType));
}
var tbodyFragment = document.createDocumentFragment();
for (var i = 0; i < rowArray.length; i++) {
tbodyFragment.appendChild(rowArray[i]);
}
tableBody.appendChild(tbodyFragment);
table.sortColumn = sortColumn;
}
function generateCompareTR(sortColumn, nodeType) {
return function compareTR(trLeft, trRight) {
var leftValue = convert(trLeft.cells[sortColumn].firstChild.nodeValue, nodeType);
var rightValue = convert(trRight.cells[sortColumn].firstChild.nodeValue, nodeType);
if (leftValue < rightValue) {
return -1;
} else {
if (leftValue > rightValue) {
return 1;
} else {
return 0;
}
}
};
}
function convert(value, dataType) {
switch (dataType) {
case "int":
return parseInt(value);
case "float":
return parseFloat(value);
case "date":
return new Date(Date.parse(value));
default:
return value.toString();
}
}
然后是使用：
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%> <% String path = request.getContextPath(); String basePath = request.getScheme() + "://" + request.getServerName() + ":" + request.getServerPort() + path + "/"; %> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <head> <base href="<%=basePath%>"> <title>My JSP 'tabel.jsp' starting page</title> <meta http-equiv="pragma" content="no-cache"> <meta http-equiv="cache-control" content="no-cache"> <meta http-equiv="expires" content="0"> <meta http-equiv="keywords" content="keyword1,keyword2,keyword3"> <meta http-equiv="description" content="This is my page"> <!-- <link rel="stylesheet" type="text/css" href="styles.css"> --> <script type="text/javascript" src="userjs/tableSort.js"></script> </head> <body> <table id="theTable" align="center" border="1"> <thead> <tr> <td> 标题1 </td> <td onclick="sort(theTable,1,'int')"> 标题2 </td> <td onclick="sort(theTable,2,'int')"> 标题3 </td> <td onclick="sort(theTable,3,'int')"> 标题4 </td> <td onclick="sort(theTable,4,'int')"> 标题5 </td> <td onclick="sort(theTable,5,'int')"> 标题6 </td> <td onclick="sort(theTable,6,'int')"> 标题7 </td> </tr> </thead> <tbody> <tr> <td> 1 </td> <td> 2 </td> <td> 3 </td> <td> 4 </td> <td> 5 </td> <td> 6 </td> <td> 7 </td> </tr> <tr> <td> 2 </td> <td> 3 </td> <td> 4 </td> <td> 5 </td> <td> 6 </td> <td> 7 </td> <td> 1 </td> </tr> <tr> <td> 3 </td> <td> 4 </td> <td> 5 </td> <td> 6 </td> <td> 7 </td> <td> 1 </td> <td> 2 </td> </tr> <tr> <td> 4 </td> <td> 5 </td> <td> 6 </td> <td> 7 </td> <td> 1 </td> <td> 2 </td> <td> 3 </td> </tr> <tr> <td> 5 </td> <td> 6 </td> <td> 7 </td> <td> 1 </td> <td> 2 </td> <td> 3 </td> <td> 4 </td> </tr> <tr> <td> 6 </td> <td> 7 </td> <td> 1 </td> <td> 2 </td> <td> 3 </td> <td> 4 </td> <td> 5 </td> </tr> </tbody> </table> </body> </html>
然后就可以看到效果了，呵呵
