複製代碼 代碼如下:
<script type="text/javascript">
var b = true ;
function sortAge(){
var tabNode = document.getElementsByTagName("table")[0];
var trNodes = tabNode.rows; //擷取表格中的行對象
var arr = new Array();
for(var x=1;x<trNodes.length;x++){ //臨時容器存入的是表格中行對象的引用
arr[x-1] = trNodes[x];
}
sort(arr);
var tbdNode = tabNode.childNodes[0];
if(b){ //if....else...控制按年齡的升降進行排序
for(var x=0;x<arr.length;x++){
tbdNode.appendChild(arr[x]);
}
b = false;
}else{
for(var x=arr.length-1;x>=0;x--){
tbdNode.appendChild(arr[x]);
}
b = true ;
}
}
function sort(arr){ // 排序
for(var x=0;x<arr.length;x++){
for(var y=x+1;y<arr.length;y++){
if(parseInt(arr[x].cells[1].innerText)>parseInt(arr[y].cells[1].innerText)){ // 不進行parseInt轉換是以字串的ASCII比較
var temp = arr[x];
arr[x] = arr[y];
arr[y] = temp;
}
}
}
}
