没错，就是这么的简陋，但是胜在代码简单。具体思路其实就是通过JavaScript函数进行input里text的value值替换，点击按钮进行增加或者减少。
function add(){
var txt=document.getElementById("txt");
var a=txt.value;
a++;
if(txt.value<16){
txt.value=a;
}
}
function sub(){
var txt=document.getElementById("txt");
var a=txt.value;
if(a>0){
a--;
txt.value=a;
}else{
txt.value=0;
}
}
最后上一下代码，由于有点长，所以只上一下html代码，JavaScript我会上传一个附件出来。

最后把JavaScript代码外链进去即可！
附件最后还是变成了云盘。
