錯(cuò)在哪里了
<script type="text/javascript">
? function? app2(x,y)
? { var sum,x,y;
? ? sum = x * y;
? ? return sum;
? }
?var req1 = app2(5,6);
?var req2 = app2(2,3);
?var sumq = req1+req2;
document.write("req1的值:"+req1+"<br/>");
document.write("req2的值:"+req2+"<br/>");
document.write(req1+"與"+req2+"和:"+sumq);
</script>

var sumq = req1+req2; 這里換成函數(shù)調(diào)用
var sumq=? app2(req1,req2);
