How to i remove the row when i click delete button?

Question

const Form = document.querySelector(".tracker-form"),
      Name = document.querySelector(".tracker-name"),
      Date = document.querySelector(".tracker-date"),
      Amount = document.querySelector(".tracker-amount"),
      Table = document.querySelector(".tracker-table"),
      tableRow = document.createElement("tr");

      
function deleteRow(event) {
    const button = event.target;
    const row = button.parentNode;

    tableRow.removeChild(row);
}

function addExpense() {
    Form.addEventListener("submit", event => {
        const tableName = document.createElement("td");
        const tableDate = document.createElement("td");
        const tableAmount = document.createElement("td");

        const delButton = document.createElement("button"); 
        delButton.innerHTML = "X";
        delButton.addEventListener("click", deleteRow);
        
        Table.appendChild(tableRow);

        tableRow.appendChild(tableName);
        tableRow.appendChild(tableDate);
        tableRow.appendChild(tableAmount);
        tableRow.appendChild(delButton);
        tableName.innerHTML = Name.value;
        tableDate.innerHTML = Date.value;
        tableAmount.innerHTML = Amount.value;

        Name.value = "";
        Date.value = "";
        Amount.value = "";

        event.preventDefault();
    })
}

function init() {
    addExpense();
}

init();

I'm making an expense tracker. When I enter a value in name, date, amount, values, and 'x' button display on each table. And I want to make a row removed when I click 'x' button. But it doesn't work. Can anyone tell me why?

Answer 1

You can simply remove the closest tr element:

function deleteRow(event) {
  event.target.closest('tr').remove();
}

Answer 2

You need to distinguish between parentNode .

parentNode: The parentNode property returns the parent node of the specified node, as a Node object.

and closest

The closest() method searches up the DOM tree for the closest element which matches a specified CSS selector

 $(".deleteRowButton").on("click", function(event){ var $closest = event.target.closest('tr'); var $parentNode = event.target.parentNode; // It just return `td` instead. console.log({closest: $closest, parentNode: $parentNode}); $closest.remove(); });

 <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script> <table> <tr><td>foo</td> <td><a class="deleteRowButton">delete_row</a></td></tr> <tr><td>bar bar</td> <td><a class="deleteRowButton">delete_row</a></td></tr> <tr><td>bazmati</td> <td><a class="deleteRowButton">delete_row</a></td></tr> </table>
