Question

function abc()
{
    var str = "";  //  -------------------(4) 
    for (var i = 0; i < 100 ; i++)
    {
        str = "<tr><td>"; // ------------------(1)
            for(var m = 1 ; m <= cnt_chapter ; m++)
        {
            str = str + "<span>" + m +"</span> "; //  -------------(2) 
        }
        str = str + "</td></tr>"; // ------------(3) 
    }                       
    $(".title").append(str);
}

This code is part of jquery code.

But don’t work (2) code.

What is the wrong of my code?

cnt_chapter is undifiend here also problem with append

var cnt_chapter = 10;
function abc()
{
    var str = "";
    for (var i = 0; i < 10 ; i++)
    {
        str += "<tr><td>";
        for(var m = 1 ; m <= cnt_chapter ; m++)
        {
            str = str + "<span>" + m +"</span> ";
        }
        str = str + "</td></tr>";
    }                       
     $(".title").append(str);
