Question

I have this function below which returns all IDs of checked boxes on my page seperated by a comma. It works great but the problem is, it seems to put a lot of white space after each checkbox ID. I can’t seem to figure out why?

/*Returns selected checkbox ID in string seperated by comma */
function get_selected_chkbox(){

    var checked_string = '';

     $('#report_table').find("input[type='checkbox']").each(function(){

        if(this.checked){

            checked_string = checked_string + this.id + ',';

        }

    });

            alert(checked_string);//test1         ,test2            ,   

    return checked_string;
}

Thanks all for any help

Answer 1

You can rewrite your function like this

var selected = new Array();
$('#report_table input:checkbox:checked').each(function(){
    selected.push($(this).attr("id"));
});

return selected.join(',');

Edit

Better to get rid of spaces in id rather than trimming the ids in javascript.
