How to get id of javascript's container?

Question

I would like to get ID of javascript's container, for ex:

<div id="d_17j_a">
   <script type="text/javascript">
      alert("<ID of javascript's container here>");
      // it will alert: d_17j_a
   </script>

Thank for any suggestion !

Are you going to have multiple scripts in a single div? or one div will contain 1 script at most? — painotpi, May 02 '13 at 09:29

So scripts are loaded sequentially, so you can get the parent node of a script element through:

var scripts = document.getElementsByTagName('script');
var me = scripts[scripts.length-1];
console.log('parent id', me.parentNode.id);

can use `document.scripts` ? – painotpi May 02 '13 at 09:26

Just note that this approach works properly only if no scripts are deffered. – dfsq May 02 '13 at 09:26
But, the SO has not mentioned anything w.r.t deferring scripts. – painotpi May 02 '13 at 09:28

<script id="FindMe" type="text/javasctipt"> should work just fine using jQuery("#FindMe").parent().id

In pure javascript

document.getElementById("FindMe").parentNode.id

If you can add an id to your script tag you can grab the parent with Javascript after retrieving the script element.

<div id="d_17j_a">
   <script id="myScript" type="text/javascript">
      var parentId = document.getElementById("myScript").parentNode.id;
      alert(parentId);
      // it will alert: d_17j_a
   </script>
</div>
