Navigate through the DOM to return an image

I have a question about clicking on the image '.escape' and passing back the source of the image '.myimg2' when clicked. Here is my attempt at accomplishing this task: I understand that it involves traversing the DOM, but I am not very familiar with how to do this effectively. Thank you in advance for any advice or guidance.

<table class="table2">
    <tr>
        <td>
            <div class="info2" ondragstart="return false" ondragover="allowDrop(event)" ondrop="drop(event)" >
                <div  style="float:left">
                    <img class="myimg2" style="max-height:80px;" src="Pictures/QuestionMark.png">
                </div>
                <div style="float:left;">
                    <p class="myname2">Name: Unspecified</p>
                    <p class="myprof2">Profession: Unspecified</p>
                </div>
                <img class="escape" onclick="returnDrop(this.parentNode.childNode[0].src)" style="max-height:8px;" src="Pictures/escape.png">
            </div>
        </td>
</tr>
</table>

When discussing IDs (#escape), using classes (.escape) instead can lead to confusion. It is recommended to switch to using IDs for uniqueness. In this example, the class attribute is used, but ideally, it should be placed in the onclick= attribute within the .escape element.

this.setAttribute('src',this.parentNode.getElementsByClassName('myimg2')[0].getAttribute('src'))

Here, the src attribute is set to the source of the first element with the class .myimg2 that is within the parent element of .escape. If there are no other elements with the class .myimg2, you could use document.get... instead of this.parentNode.get....

When using IDs instead of classes:

this.setAttribute('src',document.getElementById('myimg2').getAttribute('src'))

It is important to note that with IDs, specifying the parent node is not necessary because IDs are unique throughout the entire document for that element.
