How to call function inside itself

Question

I have a function that I want to call again inside, after the last line finishes.

Maybe it will be more understandable if I show code.

function updateQuantity(){ 
    // further code where I change same data
    // and now I want to start function again but with remembering the input element that called it previously 
    updateQuantity(this);  // I tried it this way but it doesn't work
}

Any idea?

The answer is simple, it is enough to use updateQuantity.call(this) inside the updateQuantity function - when we use call and add this, the function will start again and remember the input element that previously called updateQuantity.
