javascript - Cross-browser innerText for setting values

Let's say I have the following code:

<html>
  <head></head>
  <body>
   <div id="d">some text</div>

  <script type="text/javascript">
    var d = document.getElementByid('d');
    var innerText = d.innerText || d.textContent;

    innerText = 'new text';
  </script>
  </body>
</html>

And I want to change text value for the div tag with id='d'. Unfortunately the block code above doesn't work and the text content doesn't change.

It works if do the following recipe:

if (d.innerText) d.innerText = 'new text';
else d.textContent = 'new text';

But I dont like the recipe above because it's not compact.

Have you any suggestions why the first approach doesn't work?

Instead of multiple assignments, you can grab the property and use that

var text = ('innerText' in d)? 'innerText' : 'textContent';
d[text] = 'New text';
