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; 
  }

Python vs. JavaScript: A Comparative Analysis for DevelopersMay 09, 2025 am 12:22 AM

The main difference between Python and JavaScript is the type system and application scenarios. 1. Python uses dynamic types, suitable for scientific computing and data analysis. 2. JavaScript adopts weak types and is widely used in front-end and full-stack development. The two have their own advantages in asynchronous programming and performance optimization, and should be decided according to project requirements when choosing.

Python vs. JavaScript: Choosing the Right Tool for the JobMay 08, 2025 am 12:10 AM

Whether to choose Python or JavaScript depends on the project type: 1) Choose Python for data science and automation tasks; 2) Choose JavaScript for front-end and full-stack development. Python is favored for its powerful library in data processing and automation, while JavaScript is indispensable for its advantages in web interaction and full-stack development.

Python and JavaScript: Understanding the Strengths of EachMay 06, 2025 am 12:15 AM

Python and JavaScript each have their own advantages, and the choice depends on project needs and personal preferences. 1. Python is easy to learn, with concise syntax, suitable for data science and back-end development, but has a slow execution speed. 2. JavaScript is everywhere in front-end development and has strong asynchronous programming capabilities. Node.js makes it suitable for full-stack development, but the syntax may be complex and error-prone.

Python vs. JavaScript: Which Language Should You Learn?May 03, 2025 am 12:10 AM

Choosing Python or JavaScript should be based on career development, learning curve and ecosystem: 1) Career development: Python is suitable for data science and back-end development, while JavaScript is suitable for front-end and full-stack development. 2) Learning curve: Python syntax is concise and suitable for beginners; JavaScript syntax is flexible. 3) Ecosystem: Python has rich scientific computing libraries, and JavaScript has a powerful front-end framework.

JavaScript Frameworks: Powering Modern Web DevelopmentMay 02, 2025 am 12:04 AM

The power of the JavaScript framework lies in simplifying development, improving user experience and application performance. When choosing a framework, consider: 1. Project size and complexity, 2. Team experience, 3. Ecosystem and community support.

The Relationship Between JavaScript, C , and BrowsersMay 01, 2025 am 12:06 AM

Introduction I know you may find it strange, what exactly does JavaScript, C and browser have to do? They seem to be unrelated, but in fact, they play a very important role in modern web development. Today we will discuss the close connection between these three. Through this article, you will learn how JavaScript runs in the browser, the role of C in the browser engine, and how they work together to drive rendering and interaction of web pages. We all know the relationship between JavaScript and browser. JavaScript is the core language of front-end development. It runs directly in the browser, making web pages vivid and interesting.
