function cheekAll(){
var name=innit();
var password=passInnit();
var passIn=passIn();
var email=emailIn();
var code=code();
/*if(name&&email&&password&&passIn&&code){
return true;
}else{
return false;
}*/return false;
}
</script>
<body onload="ready()">
<form action="a.html" method="post" onsubmit="return cheekAll()" >
onsubmit中要用return check();
说明前面的代码报错了，没有执行到return false那句
