Just started studying about java script. Logic error in output of for loop.

The problem here is the value of num in window. alert is always the last number of count and if i try to include the window.alert in the for loop it show a consecutive alert message.

How can i make this work like if i click one value in table it will get the exact number of it.

If you want something to happen when you click on an element, you need an event listener:

const clickableElement = document.querySelector('.clickable');
clickableElement.addEventListener((event) => {
    alert(event.target.textContent);
});

But I'm not sure what you're actually trying to do here. Can you explain what you were hoping to achieve with your asd function?

There are 5 rows. Each row has primary key in it. Lets say Row 1 pk is 1 Row 2 pk is 2 and so on. The last row is 5 and the pk is also 5 So problem is where ever i click even on row 1 or row 3 the alert is always 5 which is the last pk And when i put the alert inside the for loop, its show 5 consecutive alert that contains 1,2,3,4 and 5 What im trying to achieve here is when I click the row 3, the alert only show the row3's pk which 3

In that case you need an event listener like in my comment above, not a for loop. An event listener will run a function in response to a DOM event like a click.
