How to useid Property in Javascript
This approach assigns an id
directly to the table element using the id
property. It doesn’t use the classList
object or method for adding classes. Useful when you need a unique identifier for the table element. Typically used when there is only one element with a specific purpose on the page.
Example: In this example we are using Id property.
HTML
<!DOCTYPE html> < html lang = "en" > < head > < meta charset = "UTF-8" > < meta name = "viewport" content = "width=device-width, initial-scale=1.0" > < title >Dynamic Table</ title > </ head > < body > < button onclick = "addRowWithIdProperty()" > Add Row (id Property) </ button > < table id = "myTableIdProperty" > <!-- Existing Table Content Goes Here --> </ table > < script > let rowCountIdProperty = 1; function addRowWithIdProperty() { const table = document.getElementById("myTableIdProperty"); const newRow = table.insertRow(-1); const cell = newRow.insertCell(0); cell.innerHTML = "Row " + rowCountIdProperty++; } </ script > </ body > </ html > |
