There is a table, cells are not always filled in it, that is, there are empty ones. How to find the smallest number in each of the lines?

    It's simple: we go around all the lines in a cycle, inside which we go around all the cells and compare them to .text() . At the end of the traversal of the next line, we have the smallest of values.

    The code might look like this:

    live example on jsfiddle: https://jsfiddle.net/ipshenicyn/51u348nc/

     $('table tr').each(function(){ var $tr = $(this); var smallest = null; $tr.find('td').each(function(){ var number = parseInt($(this).text(), 10); if(number && (smallest === null || smallest > number)) smallest = number; }); if(null !== smallest){ $tr.find('.result').text(smallest); } });

    For the sake of example, I write the smallest value in the specially allocated for it last cell of every row (bold).

    • Thanks, it was already done right. - YarNik
    • I did not spend anything, I upgraded it for myself, I looked at another answer that was higher (now it’s lower, tried to figure it out), thank you and again I looked at another answer (it finds in the whole table and it doesn’t work), so you have a plus and closed the question. - YarNik
    • Sorry for the sharpness. Misunderstood you. I decided that you mean "no longer needed, I did everything." - Ivan Pshenitsyn

     var min = Number.MAX_SAFE_INTEGER; $('td').each(function(){ if ($.isNumeric($(this).html())) if ($(this).html() < min) min = parseInt($(this).html()); }); alert(min); 
     td { border:1px solid #ccc; padding: 10px; }
