添加HTML內容與常值內容以前用的是innerHTML與innerText方法，
最近發現還有insertAdjacentHTML和 insertAdjacentText方法，
這兩個方法更靈活，可以在指定的地方插入html內容和常值內容。
insertAdjacentText方法與 insertAdjacentHTML方法類似，只不過只能插入純文字，參數相同
原型：insertAdajcentHTML(swhere,stext)
insertAdjacentHTML方法：在指定的地方插入html標籤語句
參數：
swhere: 指定插入html標籤語句的地方，有四種值可用：
1.beforeBegin: 插入到標籤開始前
2.afterBegin:插入到標籤開始標記之後
3.beforeEnd:插入到標籤結束標記前
4.afterEnd:插入到標籤結束標記後
stext：要插入的內容
