jsp+js实现可排序表格
首先，定义一个js：
/**
* 排序主方法
* @param {} tableId
* @param {} sortColumn
* @param {} nodeType
*/
function sort(tableId, sortColumn, nodeType) {
var table = document.getElementById(tableId);
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;
}
/**
* 比较函数
* @param {} sortColumn
* @param {} nodeType
* @return {}
*/
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;
}
}
};
}
/**
* 值转换
* @param {} value
* @param {} dataType
* @return {}
*/
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="GBK"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>

<base href="<%=basePath%>">
