為什么輸出結(jié)果會有問題呢？？
//定義函數(shù)
function maxvalue(x,y)
{
? ?if(x>y) return x;
? ? if(x<y)
? ? ? ?return y;
? ?if(x==y) document.write("相等");
代碼為什么有問題？？
?document.write(" 5 和 4 的較大值是:"+maxvalue(5,4)+"
");
?document.write(" 6 和 3 的較大值是:"+maxvalue(6,3)+"
" );
?document.write(" 5 和 5 的較大值是:" +maxvalue(5,5));
