您没有正确声明变量。你应该使用分号。这个应该是一个有趣的读物：Do you recommend using semicolons after every statement in JavaScript?

如果你开始使用/学习javascript eloquent javascript可能会对你有所帮助：http://eloquentjavascript.net/

这样的事情应该有效：

    var FizsBuzzOutput = '';
    var fizz = 0;
    var buzz = 0;
    var fizzbuzz=0;



    for ( var i=1; i < 100; i++ ) {


        if (i % 15 == 0){
            fizzbuzz+=1;                
            FizsBuzzOutput += "FizsBuzz, ";
        }

        else if ( i % 3 == 0 ){
            fizz+=1;
            FizsBuzzOutput += "Fizz, ";
        }


        else if (i % 5 == 0){
            buzz+=1;
            FizsBuzzOutput += "Buzz, "
        }       
        else {

            FizsBuzzOutput += i + ', ';
        }
        console.log(FizsBuzzOutput);
    }
 console.log('fizz count= '+ fizz);
 console.log('buzz count= '+ buzz);
 console.log('fizzbuzz count= '+ fizzbuzz);
