Javascript 如何在for循环中动态创建多个按钮

这是我的密码。我想在特定div中附加4个按钮。换句话说，我想将这4个按钮放在“”中。现在它工作了，但他们不在分区内

getmyItems函数是一个包含一系列信息的函数，如：标题、描述、年龄等

帮助

getmyItems（参数、函数（数据）{
var mtItem=JSON.stringify（数据）；
myItem=JSON.parse（mtItem）；
var Item=document.getElementById（'myItems'）；
对于（var i=0；i

您希望它们位于哪个特定的分区中？到目前为止，通过这种方式，四个按钮位于myItens div中，请参见和下面的代码

var getmyItems = function(data) {
    var item = document.getElementById('myItems');
    for (var i = 0; i < data.length; i++) {
        var result = data[i];

        // creation of the buffer outer div
        var buffer = document.createElement('div');
        buffer.className = 'act-time';

        //creation of de activity-body
        var activity = document.createElement('div');
        activity.className = 'activity-body act-in';

        //creation of the first span
        var arrow = document.createElement('span');
        arrow.className = 'arrow';

        //creation of the most inner div
        var textDiv = document.createElement('div');
        textDiv.className = 'text';

        //creation of the content of the most inner div
        var attribution = '';
        attribution += '<p class="attribution">';
        attribution += '<a href="#">' + result.title + '</a>';
        attribution += result.description;
        attribution += '</p>';

        //initialize the text div
        textDiv.innerHTML = attribution;

        //put the arrow span inside the activity div
        activity.appendChild(arrow);

        // put the text div inside the activity div
        activity.appendChild(textDiv);

        //put the activity inside the buffer div
        // each time appendChild is applied the element is attach tho the end of the target element
        buffer.appendChild(activity);

        var div = document.createElement('div');
