Question

Is there a way to get an object or it’s id within a script lies using jQuery or something?

For example:

<div id="div1">
  <script type="text/javascript">
     var obj = ?? // this should be the "div1" div
  </script>
</div>

In this example, obj should be equal to “div1” (or the object itself).

Another one:

<p id="paragraph_7">
  <script type="text/javascript">
     var obj = ?? // this should be the "paragraph_7" p
  </script>
</p>

In this example, obj should be equal to “paragraph_7” (or the object itself).

If I give an “id” to the script tag and then get it’s parent should work, but is there another way? not always i’m able to know the <script> id.

Thanks in advance.

Answer 1

Since scripts are executed sequentially, the currently executed script tag is always the last script tag on the page until then. So, to get the script tag, you can do:

var scripts = document.getElementsByTagName( 'script' );
var thisScriptTag = scripts[ scripts.length - 1 ];

You could then use this:

var obj = thisScriptTag.parentNode;
