Question

$(document).ready(function(){
        $(".role").change(function(){
            var userId=$(this).attr('name');
            return $("form[id=userId]").submit(); 
        });
    })

In the above code, I already checked that 'userId' gets an appropriate value through printing its value through 'alert'. Also, I already checked that $("form[id='1']").submit(); is okay.

However, the above code doesn’t work. I don’t know why.

Answer 1

The string should be concatenated

$(document).ready(function(){
    $(".role").change(function(){
        var userId=$(this).attr('name');
        return $("form[id=" + userId + "]").submit(); 
    });
})
