Nit: doctype.

[ramya.v, 2015/03/24 05:29:19]

Done.

+window.onload = function(evt) {

You don't need an onload handler. Just put the script at the end of the page.

Done.

You should use js-test.js instead of rolling this logic yourself.

[ramya.v, 2015/03/24 05:29:19]

Done.

+  document.getElementById("result").innerHTML = result;

+<p>Test for <a href="https://code.google.com/p/chromium/issues/detail?id=346473">bug
+346473</a>: Text selection should happen even if mousemove event is cancelled,
+since there is no default action specified for mousemove event in the spec which
+is to be prevented on defaultPrevent.</p>

[leviw_travelin_and_unemployed, 2015/03/19 12:56:11]

"defaultPrevent"

Also since this is easy to test manually, you should explain how.
