完整例子如下：
<html> <head> <title>Table Sort Example</title> <script type="text/javascript"> //转换器，将列的字段类型转换为可以排序的类型：String,int,float function convert(sValue, sDataType) { switch(sDataType) { case "int": return parseInt(sValue); case "float": return parseFloat(sValue); case "date": return new Date(Date.parse(sValue)); default: return sValue.toString(); } } //排序函数产生器，iCol表示列索引，sDataType表示该列的数据类型 function generateCompareTRs(iCol, sDataType) { return function compareTRs(oTR1, oTR2) { var vValue1 = convert(oTR1.cells[iCol].firstChild.nodeValue, sDataType); var vValue2 = convert(oTR2.cells[iCol].firstChild.nodeValue, sDataType); if (vValue1 < vValue2) { return -1; } else if (vValue1 > vValue2) { return 1; } else { return 0; } }; } //排序方法 function sortTable(sTableID, iCol, sDataType) { var oTable = document.getElementById(sTableID); var oTBody = oTable.tBodies[0]; var colDataRows = oTBody.rows; var aTRs = new Array; //将所有列放入数组 for (var i=0; i < colDataRows.length; i++) { aTRs[i] = colDataRows[i]; } //判断最后一次排序的列是否与现在要进行排序的列相同， //是的话，直接使用reverse()逆序 if (oTable.sortCol == iCol) { aTRs.reverse(); } else { //使用数组的sort方法，传进排序函数 aTRs.sort(generateCompareTRs(iCol, sDataType)); } var oFragment = document.createDocumentFragment(); for (var i=0; i < aTRs.length; i++) { oFragment.appendChild(aTRs[i]); } oTBody.appendChild(oFragment); //记录最后一次排序的列索引 oTable.sortCol = iCol; } </script> </head> <body> <p>Click on the table header to sort in ascending order.</p> <table> <thead> <tr> <th>Last Name</th> <th>First Name</th> <th>Birthday</th> <th>Siblings</th> </tr> </thead> <tbody> <tr> <td>Smith</td> <td>John</td> <td>7/12/1978</td> <td>2</td> </tr> <tr> <td>Johnson</td> <td>Betty</td> <td>10/15/1977</td> <td>4</td> </tr> <tr> <td>Henderson</td> <td>Nathan</td> <td>2/25/1949</td> <td>1</td> </tr> <tr> <td>Williams</td> <td>James</td> <td>7/8/1980</td> <td>4</td> </tr> <tr> <td>Gilliam</td> <td>Michael</td> <td>7/22/1949</td> <td>1</td> </tr> <tr> <td>Walker</td> <td>Matthew</td> <td>1/14/2000</td> <td>3</td> </tr> </tbody> </table> </body> </html>
