添加HTML内容与文本内容以前用的是innerHTML与innerText方法，最近发现还有insertAdjacentHTML和
insertAdjacentText方法，这两个方法更灵活，可以在指定的地方插入html内容和文本内容。
insertAdjacentHTML方法：在指定的地方插入html标签语句
原型：insertAdajcentHTML(swhere,stext)
参数：
swhere: 指定插入html标签语句的地方，有四种值可用：
1. beforeBegin: 插入到标签开始前
2. afterBegin:插入到标签开始标记之后
3. beforeEnd:插入到标签结束标记前
4. afterEnd:插入到标签结束标记后
stext：要插入的内容
