加html内容(insertAdjacentHTML和insertAdjacentText)
  dhtml提供了两个方法来进行添加，insertAdjacentHTML和insertAdjacentText 
insertAdjacentHTML方法：在指定的地方插入html标签语句。
  原型：insertAdjacentHTML(swhere,stext) 
  参数： 
  swhere:指定插入html标签语句的地方，有四种值可以用： 
  1.beforeBegin:插入到标签开始前 
  2.afterBegin:插入到标签开始标记后 
  3.beforeEnd:插入到标签结束标记前 
  4.afterEnd:插入到标签结束标记后
