IE8,firstChild.data.length undefind

[LincWong]

in IE8, this will be error. `

4444

    </div>
    <script></script>
    <script type="text/javascript">
        var a = document.getElementById("etDiv");
        var b = a.firstChild;
        alert(b.data.length);
    </script>`

because b.data is undefined in IE8

You are right, b don't have an attribute 'data'. But this is not the issue about react.

Thank you all the time!
