2 Comments

Below example is for sorting HTML table on ascending and descending order after click on header name. Based on sorting will display ascending and descending images.

Source Code

Copy your ascending and descending images on images folder and change path according to you project configuration.


Sort Table

var order;
function sortTable(col)
{
	changeSortHeaderImage(col);
	//get list of all rows of table content except header
	var rows=$('#employeeTbl tbody tr').get();

	rows.sort(function(a,b){
	var A= $(a).children('td').eq(col).text().toUpperCase();
	var B= $(b).children('td').eq(col).text().toUpperCase();
	//sort in ascending order
	if(order=="asc")
		{
	return (A <b> B) ? 1 : 0);
		}
	//sort in descnding order
	if(order=="desc")
		{
	return (B <a> A) ? 1 : 0);
		}
	});
	//iterate each row of table for changing order
	$.each(rows, function(index, row) {
	    $('#employeeTbl').children('tbody').append(row);
	  });
}
//Change image for column sorting
function changeSortHeaderImage(col)
{	

	var imgArr= document.getElementById("employeeTbl").getElementsByTagName('input');
    var altAtr;
    for (i = 0; i &lt; imgArr.length; i++) {

            altAtr=imgArr[i].getAttribute(&quot;alt&quot;);

              if(i==col &amp;&amp; &quot;asc&quot; == altAtr)
                 {
                    imgArr[i].setAttribute(&quot;src&quot;, &quot;images/desc.png&quot;);
                    imgArr[i].setAttribute(&quot;alt&quot;, &quot;desc&quot;);
                    order=&quot;desc&quot;;
                  }
           else if (i==col &amp;&amp; (&quot;nosort&quot; == altAtr ||  &quot;desc&quot; == altAtr))
                 {
                 imgArr[i].setAttribute(&quot;src&quot;, &quot;images/asc.png&quot;);
                 imgArr[i].setAttribute(&quot;alt&quot;, &quot;asc&quot;);
                 order=&quot;asc&quot;;
                 }
           else
                 {
                 imgArr[i].setAttribute(&quot;src&quot;, &quot;images/nosort.png&quot;);
                 imgArr[i].setAttribute(&quot;alt&quot;, &quot;nosort&quot;);
                 }
           }
