Javascript implements sorting operation of table elements_javascript skills
We can see many things that can be sorted on the Internet, such as size, time, price, etc.
Now let’s also try the sorting function:
Sorting function code: It contains sorting after clicking - restoring, and ascending and descending order.
function sortAge(){
//对年龄进行排序，要先进行获得每一行对象，然后对象对象中的第一个（从0 开始）的大小进行排序
var tabNode = document.getElementById("tabid");
var rows0 = tabNode.rows;
var rows1 = [];
//现将元素拷贝一份出来， 第一行不用排序
for (var x = 1; x < rows0.length; x++) {
rows1[x - 1] = rows0[x];
}
for (var x = 0; x < rows1.length - 1; x++) {//每个元素是行对象
for (var y = x + 1; y < rows1.length; y++) {
//对每一行的内容进行解析成数字
if (parseInt(rows1[x].cells[1].innerHTML) > parseInt(rows1[y].cells[1].innerHTML)) {
//alert("aa="+x+":"+rows1[x].cells[1].innerHTML);
//alert("bb"+rows1[y].cells[1].innerHTML);
var temp = rows1[x];
rows1[x] = rows1[y];
rows1[y] = temp;
}
}
}
/* 点击之后排序，排序之后恢复之前的状态
if (flag){
for (var x = 0; x < rows1.length; x++) {
// tabNode.childNodes[0].appendChild(rows[x]);//方法一： 不一定兼容
rows1[x].parentNode.appendChild(rows1[x]);
}
}else{
for (var x = 1; x < rows0.length; x++) {
// tabNode.childNodes[0].appendChild(rows[x]);//方法一： 不一定兼容
rows0[x].parentNode.appendChild(rows0[x]);
}
}
flag=!flag;*/
/* 下面的是点之后出现正序和逆序显示 正序和逆序的区别就是appendchild的前后关系而已*/
var ageimg=document.getElementById("ageid");
if (flag) {
for (var x = 0; x < rows1.length; x++) {//排好序之后就从0开始
// tabNode.childNodes[0].appendChild(rows[x]);//方法一： 不一定兼容
rows1[x].parentNode.appendChild(rows1[x]);
}
ageimg.innerHTML="年龄▲";//设置上面的图标
}else{
for (var x = rows1.length-1; x >=0; x--) {
// tabNode.childNodes[0].appendChild(rows[x]);//方法一： 不一定兼容
rows1[x].parentNode.appendChild(rows1[x]);
}
ageimg.innerHTML="年龄▼"
}
flag=!flag;
loading();//排序之后还要对颜色重新设置
}
Set the background color code of the table, imported css:
function loading(){
var name;
var tabNode=document.getElementById("tabid");
var rows=tabNode.rows;//获得每一行的数组对象
var rowslength=rows.length;//每一行的长度
for(var x=1;x<rowslength;x++){//根据每一个去设置
if(x%2==0){
rows[x].className="one";
}else{
rows[x].className="two";
}
//当移动上去之后，之前的颜色要记录下来，不然移下来之后全部都是一个颜色了
rows[x].onmouseover=function(){
name=this.className;
this.className="three";
}
rows[x].onmouseout=function(){
this.className=name;
}
}
}
onload=function(){
loading();
}
css code:
table td a:hover{
background-color:#0080c0;
}
.one{
background-color:#80ff00;
}
.two{
background-color:#ff8040;
}
.three{
background-color:#008040;
}
table{
width:500px;
height:500px;
border:#400040 solid 2px;
border-collapse:collapse;
}
table td,th{
border:solid 2px;
}
table th{
background-color:#c0c0c0;
