When thereâs not enough of these hormones, your body has trouble with these basic functions. That causes the symptoms of adrenal insufficiency -- fatigue, muscle weakness, low appetite, weight loss, and belly pain, among others. You can have either primary or secondary adrenal insufficiency.
In the DOM event model, there is a clear distinction between an event listener and a listener function: an event listener is an instance of a class that implements the EventListener interface, whereas a listener function is a method of that class named handleEvent().
In the parentheses, list the event listener but without the on. (In this example, the event listener is onclick, which is shortened to click.) You then add the function to run. (The function is declared elsewhere.) The false refers to an advanced, rarely used parameter for event handling.
