这里是我的代码。我想在特定div中添加4个按钮。换句话说，我想将这4个按钮放在＆＃39;中。现在它可以工作，但它们不在div内。
getmyItems函数是一个包含一系列信息的函数，例如：title，description，age，....
帮助
getmyItems(param, function(data) {
var mtItem = JSON.stringify(data);
myItem = JSON.parse(mtItem);
var Item = document.getElementById('myItems');
for (var i = 0; i < myItem.results.length; i++) {
var buffer = "";
buffer += '<div class="act-time">';
buffer += '<div class="activity-body act-in">';
buffer += '<span class="arrow"></span>';
buffer += '<div class="text">';
buffer += '<p class="attribution">';
buffer += '<a href="#">'+myItem.results[i].title+'</a>';
buffer += myItem.results[i].description;
buffer += '</p>';
buffer += '</div>';
buffer += '</div>';
buffer += '</div>';
var div = document.createElement('div');
div.innerHTML = buffer;
//var elem = div.firstChild;
Item.appendChild(div);
var btn = document.createElement('input');
btn.setAttribute('type', 'button');
btn.setAttribute('class', 'btn btn-danger');
btn.value = "Delete";
btn.onclick = (function(i) {
return function() {
var c=confirm('Are you Sure? ');
if (c==true)
doDelete(myItem.results[i].item_id);
};
})(i);
Item.appendChild(btn);
var show_btn=document.createElement('input');
show_btn.setAttribute('type','button');
show_btn.setAttribute('class','btn btn-primary');
show_btn.value="ShowInDetail";
show_btn.onclick=(function(i){
return function(){
showInDetail(myItem.results[i]);
window.location='showInDetail.html';
};
})(i);
Item.appendChild(show_btn);
var extend_btn=document.createElement('input');
extend_btn.setAttribute('class','btn btn-warning');
extend_btn.setAttribute('type','button');
extend_btn.value="Extend";
extend_btn.onclick=(function(i){
return function(){
extendItem(myItem.results[i]);
window.location='extendItem.html';
};
})(i);
Item.appendChild(extend_btn);
var bookmark=document.createElement('input');
bookmark.setAttribute('type','button');
bookmark.setAttribute('class','btn btn-primary');
bookmark.value='Bookmark';
bookmark.onclick=(function(i){
return function(){
var p={user_id:localStorage.getItem('user_id')};
window.localStorage.setItem('this_item_id', myItem.results[i].item_id);
getBookmarks(p, function(d){
var bk=JSON.stringify(d);
bk=JSON.parse(bk);
if(bk.results){
var l=0;
for(var j in bk.results){
if(bk.results[j].item_id==localStorage.getItem('this_item_id')){
removeBookmark(bk.results[j]);
l=1;
}
}if(l==0){
addBookmark(myItem.results[i]);
}
}else{
addBookmark(myItem.results[i]);
}
});
};
})(i);
Item.appendChild(bookmark);
//document.getElementById(i).appendChild(btn);
}
});

你想要什么特定的div？到目前为止，通过这种方式，四个按钮位于myItens div内，请参阅fiddle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');
div.appendChild(buffer);
item.appendChild(div);
var btn = document.createElement('input');
btn.setAttribute('type', 'button');
btn.setAttribute('class', 'btn btn-danger');
btn.value = "Delete";
btn.onclick = (function(i) {
return function() {
var c = confirm('Are you Sure? ');
if (c === true) {
//do something;
};
};
})(i);
// now that all div are created you can choose which div you want to put the button inside.
// in this I chose the buffer.
buffer.appendChild(btn);
var showBtn = document.createElement('input');
showBtn.setAttribute('type', 'button');
showBtn.setAttribute('class', 'btn btn-primary');
showBtn.value = "ShowInDetail";
showBtn.onclick = (function(i) {
return function() {
window.location = 'showInDetail.html';
//do something
};
})(i);
// button is append to the end of the buffer
buffer.appendChild(showBtn);
var extendBtn = document.createElement('input');
extendBtn.setAttribute('class', 'btn btn-warning');
extendBtn.setAttribute('type', 'button');
extendBtn.value = "Extend";
extendBtn.onclick = (function(i) {
return function() {
window.location = 'extendItem.html';
//do something
};
})(i);
// button is append to the end of the buffer
buffer.appendChild(extendBtn);
var bookmark = document.createElement('input');
bookmark.setAttribute('type', 'button');
bookmark.setAttribute('class', 'btn btn-primary');
bookmark.value = 'Bookmark';
bookmark.onclick = (function(i) {
return function() {
var p = { user_id: localStorage.getItem('user_id') };
window.localStorage.setItem('this_item_id', myItem.results[i].item_id);
//do something
};
})(i);
// button is append to the end of the buffer
buffer.appendChild(bookmark);
}
};
var myItem = [{ title: 'person', description: 'familyName' }, { title: 'ohterPerson', description: 'otherFamilyName' }];
getmyItems(myItem);
