can inline JavaScript get its parent node in all browsers?

Question

my question is quite easy. code as belows:

<div id="parent">
  <script>
    // will this line be an error ? cannot find the dom?
    var dom = document.getElementById("parent");
  </script>
</div>

I test it in all broswers I can find, even IE6, it works well! But I wonder if any browser will make an error? Because after putting the code onto the network, some data tell me that it may result in an error? but how ? could you help me?

@2017.09.13 it seems to be a misunderstand, the code is ok

"some data tell me that it may result in an error"; what is "some data"? What other information was given? — James Donnelly, Mar 02 '16 at 10:15
Well it kinda is, because the error message may be specific to whatever tool it is which is giving you the message. You may then be able to look that up and directly find an answer to this. — James Donnelly, Mar 02 '16 at 10:27

Your script should always be able to find its container element, because the element is included on the page before the script runs. but:

Modifying the DOM before it is completely loaded may result in problems in older browsers: https://stackoverflow.com/a/403992/5742681
There may be problems accessing any child elements that are included in the parent after the script through the variable defined in the div.

Overall, it would probably be better to put your script outside the div.
