如何防止在JS中调用另一个函数？

Question

function datePicker(event)
{
//do something`enter code here`
}

document.onclick=function() {
//do something
}

When I call datePicker() function I want to prevent the calling second method . How to do that ?

Answer 1

Use event.stopPropagation() to stop the event bubbling up to the document click listener:

function datePicker(event)
{
    event.stopPropagation();
}

You can also use event.stopImmediatePropagation() to stop sibling elements receiving the event too, if necessary: jquery: stopPropagation vs stopImmediatePropagation
