jquery set all checkbox checked

Question

I am using jquery 1.11.1 and this is my code:

$(\"#rowchkall\").change(function(){
    if($(this).is(\':checked\')){
        $(\"input:checkbox[class=rowchk]         


        

Answer 1

Try to use .prop() instead of .attr()

$("#rowchkall").change(function(){
  $("input:checkbox[class=rowchk]").prop('checked', this.checked);
});

And you don't need to iterate over all the elements to change its property.
