尽管这是一个非常棘手的解决方案，但由于它仍然是公认的答案，因此我将Gabi的代码合并到其中，而我自己的代码将成为一个不好的例子。
<style>.A {background: blue;}.B {font-style: italic;}.C {font-weight: bold;}</style><script>// my hacky approach:function get_content() { var html = document.getElementById("txt").innerHTML; document.getElementById("txt").innerHTML = html.replace(/<[^>]*>/g, "");}// Gabi's elegant approach, but eliminating one unnecessary line of pre:function gabi_content() { var element = document.getElementById('txt'); element.innerHTML = element.innerText || element.textContent;}// and exploiting the fact that IDs pollute the window namespace:function txt_content() { txt.innerHTML = txt.innerText || txt.textContent;}</script><input type="button" onclick="get_content()" value="Get Content (bad)"/><input type="button" onclick="gabi_content()" value="Get Content (good)"/><input type="button" onclick="txt_content()" value="Get Content (shortest)"/><p id='txt'><span >I am</span><span >working in </span><span >ABC company.</span></p>
