相信很多人都见过瀑布流图片布局，那些图片是动态加载出来的，效果很好，对服务器的压力相对来说也小了很多，用鼠标操作的时候相信都见过这样的效果：进入qq空间，向下拉动空间，到底部时，会动态加载剩余的说说或者是日志 ，今天我们就来看看他们的实现思路和js控制动态加载的代码。
window.onscroll = function() {
varscrollTop = document.body.scrollTop;
varoffsetHeight = document.body.offsetHeight;
varscrollHeight = document.body.scrollHeight;
if(scrollTop == scrollHeight - offsetHeight) {
page++;
loadList(page);
}
};
functionloadList(page) {
page = page || 1;
if(isLoad) {
getJSON('/forum.php?mod=hot&page='+ page).then(function(data) {
if(data.code == 200) {
data = data.data;
if(data && Object.keys(data).length > 0) {
for(vark indata) {
varv = data[k];
detailTemplate = detailTemplate.cloneNode(true);
varuserInfoObj = detailTemplate.getElementsByClassName('user-info')[0];
userInfoObj.getElementsByClassName('name')[0].innerText = v.author;
userInfoObj.getElementsByClassName('avatar')[0].src = v.avatar;
userInfoObj.getElementsByClassName('post-time')[0].innerHTML = v.lastpost;
detailTemplate.getElementsByClassName('title')[0].innerText = v.subject;
detailTemplate.getElementsByClassName('desc')[0].innerText = v.subject;
varextInfoObj = detailTemplate.getElementsByClassName('ext-info')[0];
extInfoObj.getElementsByClassName('from')[0].innerText = v.fname;
extInfoObj.getElementsByClassName('view-time')[0].innerText = v.views;
postListObj.appendChild(detailTemplate);
}
} else{
isLoad = false;
}
} else{
isLoad = false;
}
}, function(status) {
console.log('Something went wrong, status is '+ status);
});
}
}
