How to retrieve values ​​of unselected rows in HTML data table using jquery

Question

I'm trying to get the value of all rows where the button was not clicked. For example, when I click a button on the first row, I want to retrieve the value of the row that was not clicked.

 
var table = document.getElementById("all_department");
if (table != null) {
  for (var i = 0; i < table.rows.length; i++) {
  table.rows[i].onclick = function() {
  tableText(this);
      }
    }
  }    
    
function tableText(tableRow) {
var myJSON = JSON.stringify(tableRow);
console.log(myJSON);
}

    <table id="all_departments">
     <thead>
              <th><button>click</button></th>                                   
              <th>Departments</th>
              <th>Creation Date</th>
              <th>Name</th>
     </thead>
    <tbody class="bl">
           <tr>
                <td><button>click</button></td>
                <td>Management</td>
                <td>2-3-2016</td>
                <td>client x</td>
          </tr>
    
           <tr>
                <td><button>click</button></td>
                <td>Sales</td>
                <td>25-6-2019</td>
                <td>client y</td>
          </tr>
    </tbody>
    </table>

You can listen to the click handler on the button, get the parent tr of the clicked button, and then get the sibling button.

Once we have all siblings we can loop through them and form our resulting string.

Please refer to the code below

const allBtns = document.querySelectorAll('button');
allBtns.forEach(function(btn) {
  btn.addEventListener('click', function(e) {
    let elem = this.closest('tr');
    const siblings = getSiblings(elem);
    const result = [];
    siblings.map(ele => {
      ele.querySelectorAll('td').forEach((e, i) => {
        if (i !== 0) {
          result.push(e.innerText);
        }
      });
    });
    console.log(result.join(','));
  })
});

const getSiblings = function(e) {
  let siblings = [];
  if (!e.parentNode) {
    return siblings;
  }

  let sibling = e.parentNode.firstChild;

  while (sibling) {
    if (sibling.nodeType === 1 && sibling !== e) {
      siblings.push(sibling);
    }
    sibling = sibling.nextSibling;
  }
  return siblings;
};

click	Departments	Creation Date	Name
click	Management	2-3-2016	client x
click	Sales	25-6-2019	client y
