outerHTML data is not complete

Question

HTML:

<div id="WholeNew">
    <script>func2()</script>
    <img src="x" onerror=func1() />
</div>

JS:

function func1()
{
    console.log(arguments.callee.caller.arguments[0].target.parentNode.outerHTML);
}

function func2()
{
    console.log(document.currentScript.parentNode.outerHTML);
}

Now look at the output in console:

For func1():

<div id="WholeNew">
    <script>func2()</script>
    <img src="x" onerror=func1() />
</div>

For func2():

<div id="WholeNew">
    <script>func2()</script>
</div>

Why there's a difference in both outputs, as the element in document.callee.caller.arguments[0].target of func1() document.currentScript.parentNode of func2() is the same <div>? I need complete outerHTML of <div> from func2().

Answer 1

The problem is that when asking for document.currentScript.parentNode the document is not yet ready. Try to retrieve the outerHTML on DOMContentLoaded:

function func2()
{
    currentScriptReference = document.currentScript;
    document.addEventListener('DOMContentLoaded', function(){
      console.log(currentScriptReference.parentNode.outerHTML);
    }, false);
}

The result of console log:

<div id="WholeNew">
    <script>func2()</script>
    <img src="x">
</div>
