textContent in IE8

By Eli Grey 22 comments

I was creating a testcase for a bug that is present in every browser and I noticed IE still doesn’t support textContent as of IE8. I don’t like having to make code that supports both innerText and textContent so I implemented the standard myself using IE8’s support for ECMAScript 3.1 accessors. The following is all the code that you need to make textContent work in IE8.

if (Object.defineProperty && Object.getOwnPropertyDescriptor &&
     Object.getOwnPropertyDescriptor(Element.prototype, "textContent") &&
    !Object.getOwnPropertyDescriptor(Element.prototype, "textContent").get)
  (function() {
    var innerText = Object.getOwnPropertyDescriptor(Element.prototype, "innerText");
    Object.defineProperty(Element.prototype, "textContent",
      { // It won't work if you just drop in innerText.get
        // and innerText.set or the whole descriptor.
        get : function() {
          return innerText.get.call(this)
        },
        set : function(x) {
          return innerText.set.call(this, x)
        }
      }
    );
  })();

Save it as textContent.js and then include the following code to use it.

<!--[if gte IE 8]><script type="text/javascript" src="textContent.js"></script><![endif]-->
