有没有办法用.innerHTML向DOM对象添加信息而不替换那里存在的东西？
例如: document.getElementById('div').innerHTML = 'stuff';
会回来 <div id="div">stuff</div>
然后是一个类似的电话: document.getElementById('div').innerHTML = ' and things';
将div设置为 <div id="div">stuff and things</div>
我是所有事情的初学者,我曾多次尝试将图像(透明png)放在中心的桌子上,但由于某种原因,图形不会从浏览器的左上角移开.绝对定位应该允许我将元素放置在我想要的任何地方.如果有人可以帮助确定我做错了什么,我真的很感激.
