javascript - 用JS创建动态输入类型

Question

有人能告诉我为什么这不起作用吗？

我的目标是创建一个列表输入类型并为每个输入类型分配一个类

var container = document.createElement('div');
container.setAttribute('id','Maincontainer');
document.body.append(container);


var count = ['class1','class2','class3','class4','class5'];
var i;
for( i = 0; i <= count.length; i++){
    container.innerHTML += '<input>';
}


count.forEach( function(){
    count = document.getElementsByTagName('input');
    count.setAttribute('class',i);
});

Answer 1

var container = document.createElement('div');
container.setAttribute('id','Maincontainer');
document.body.append(container);


var count = ['class1','class2','class3','class4','class5'];
var i;
for( i = 0; i <= count.length; i++){
    container.innerHTML += '<input type="button">';
}


count.forEach( function(c, i){
    count1 = document.getElementsByTagName('input')[i];
    count1.setAttribute('class',c);
});
