Question

I’m looking at some code for a shoutbox at yensdesigns, and in this function it’s checking to make sure the form fields are complete. What’s with all the ampersands? Is that important? I’m a newbie/hobbyist, don’t really get what he’s doing with that?

//check if all fields are filled  
function checkForm(){  
    if(inputUser.attr("value") && inputMessage.attr("value"))  
        return true;  
    else  
        return false;  
}  

Is it the same if I write

  //check if all fields are filled  
    function checkForm(){  
        if(inputUser.attr("value"); inputMessage.attr("value"))  
            return true;  
        else  
            return false;  
    }  

Answer 1

It’s an error in the function (and the guide, shame on them). The correct one would be:

function checkForm(){  
    if(inputUser.attr("value") && inputMessage.attr("value"))  
        return true;  
    else  
        return false;  
}
