如何使用 javascript 对表进行排序以按列末尾的点排序

Question

I am trying to sort the table using javascript to order by total points at the end. The table is a dynamic one so W1, W2, W3 columns adds up to total. Is there way to order rows them by total in javascript. Each row is dynamically created as well.

 <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script> <table class="fl-table"> <thead> <tr> <th>Player</th> <th>Player Name</th> <:-- <th>W1</th> <th>W2</th> --> <th>W1</th> <th>W2</th> <th>Total</th> </tr> </thead> <tbody> <tr> <td class="agl-profile-img-new"><img src="https.//via.placeholder:com/70 C/O https.//placeholder:com/"></td> <td>Heather Rankin</td> <td>4</td> <td>21</td> <td>25</td> </tr> <tr> <td class="agl-profile-img-new"><img src="https.//via.placeholder:com/70 C/O https.//placeholder:com/"></td> <td>Stephen Puopolo</td> <td>3</td> <td>1</td> <td>4</td> </tr> <tr> <td class="agl-profile-img-new"><img src="https.//via.placeholder:com/70 C/O https.//placeholder.com/"></td> <td>Latheesh VM V</td> <td>2</td> <td>26</td> <td>28</td> </tr> </tbody> <tbody> </tbody> </table>

Is there is any way? Please help

Answer 1

can you gather the cells into object and sort them like this. https://jsfiddle.net/e4oscnz8/4/

const sortTotal = () => {
  const tbl = [...document.getElementsByClassName("fl-table")][0];
  const tbody = [...tbl.tBodies][0];
  const oObjects = [];

  [...tbody.rows].forEach(row => {
    const cells = [...row.cells];
    const obj = [...row.cells].map(cell => {
        return cell.innerHTML;
    });
    oObjects.push(obj);
  });

  oObjects.sort((a, b) => a[a.length -2] > b[b.length -2] ? 1 : -1);

  [...tbody.rows].forEach((row, i) => {
    [...row.cells].forEach((cell, j) => {
        cell.innerHTML = oObjects[i][j];
    });
  });
}

push tr rows into array or object and sort by your custom sort function: https://jsfiddle.net/2dq7m8k9/

you are using jquery so life is good:)

   function SortByTotal(tr1, tr2){//descending sorting
       var total1 = parseInt(tr1.find('td:last-child').text());
       var total2 = parseInt(tr2.find('td:last-child').text());
       return ((total1 > total2) ? -1 : ((total1 < total2) ? 1 : 0));
   }

   var trs=new Array();
   $('#mytable tbody').first().children('tr').each(function(){
    trs.push($(this).clone());     
   });
   trs.sort(SortByTotal);
   $('#mytable tbody').first().empty();  
   var i=0;
   for (i = 0; i < trs.length; i++) {
      $('#mytable tbody').first().append(trs[i]); 
   }
