How to fetch contents of clicked cell in a dynamic table using javascript

Question

I have tables present. Now if I click any of the below table names, like feedback, how can I get the values for them. table is dynamic. Below is code for displaying table names.

<table class="table  table-hover" style="margin-top: 25px;width:300px;">
  <thead>
    {% for i in tables %}
    <tr>
      <th > {{ i }} </th>
    </tr>
      {% endfor %}
  </thead>
</table>

Note, i is value of table name.

Here I want to add 2 things:

1. A click listener
2. Get the values by clicking on the tables using JavaScript

Answer 1

To get the element clicked, you can listen for click events on the table, then use the event.target property to get the element that was clicked.

// set up the 'click' event listener
myTable.addEventListener('click', event => {
  const clickedElement = event.target;

  // now that you have the clicked element, do what you want with it
  let stuffIWant = clickedElement.<some method or property of element>;
});

From the example in the question, it appears that you looking for the contents of a <th> element. If that's the case, you can use:

stuffIWant = clickedElement.innerText;

A working example:

// listen for all 'click' events within table
const tbl = document.getElementById('tbl');
tbl.addEventListener('click', event => {
  const el = event.target;
  alert(`you clicked "${el.innerText}"`);
});

#tbl {
  background-color: #aaa;
  margin: 12px;
}
th {
  padding: 0.5rem 2rem;
  border: 1px solid #999;
}
/* change cursor to hand on hover */
th:hover {
  cursor: pointer;
}

<table id="tbl">
  <thead>
    <tr><th>Feedback</th></tr>
    <tr><th>Complaint</th></tr>
    <tr><th>Praise</th></tr>
  </thead>
</table>
