<a href="about.html" onclick="return verify();"><span>go</span></a>

function verify(){
    var isValid = false; // do your check!
    if (!isValid) {
         alert("some message");
    }
    return isValid;
}

The function verify should return false if you want to stop the link navigation. return true to continue to about.html.

e.g.

 function verify(){
    //verify stuff
    if(it is verified){
        return true;
     }else{
        alert("problems");
        return false;
    }
 }

If verify returns true, it will jump the link. If it returns false, you will not go to about.html. You can choose to show an alert if you like. It will not influence this flow.
