(转载)innerHTML,innerTEXT,outerHTML的区别

         

   innerHTML,  innerTEXT,  outerHTML的区别如下图:

              

举个例子

<p id="my"><span>temp</span></p> 

++++++++++++++++++++++++++++++++

document.getElementById("my").innerText = "aaa";
//显示: <p id="my"><span>aaa</span></p>

document.getElementById("my").innerHTML = "<strong>bbb</strong>";
//显示: <p id="my"><strong>bbb</strong></p>

document.getElementById("my").outerHTML= "<h1>ccc</h1>";
//显示: <h1>ccc</h1>

++++++++++++++++++++++++++++++++

var innerText = document.getElementById("my").innerText;
// innerText = "temp";

var innerHTML = document.getElementById("my").innerHTML;
// innerHTML = "<span>temp</span>";

var outerHTML = document.getElementById("my").outerHTML;
// outerHTML = "<p id=my><span>temp</span></p>"; 

innerHTML　对下面的标签只读： 
html,　style,　table,　tbody,　tfoot,　thead,　title,　tr

td,tr,tbody　的outerHTML　为只读
