如何执行绑定到事件的侦听器并排除绑定到执行中的不同事件的其余侦听器？

Question

I have the following jQuery code:

$input.on('keyup', keyUpListener);

$input.on('input', inputListener);

// IE <= 8 fallback for input event.
$input[0].onpropertychange = function() {
    if (window.event.propertyName === "value") {                
        inputListener(window.event);
    }
};

$input is a jQuery input[type='text'] .

Right now keyUpListener and inputListener are both executed when I type into the input or when I copy and paste something ( onpropertychange is not fired because it is an IE only event).

But how can I tell JS to not fire inputListener if keyUpListener is executing and vice-versa?

Answer 1

Attach the specific event to the textbox?

$("#input").on('input', function () {
}

For instance the above - this way you can have multiple listeners not executing on the same input

EDIT

You are able to bind the paste function to the textbox also..

$("#input").bind('paste', function() {
var pasted = true;
}); 

Thus you can then have the below IF statement:

if (pasted) {
$input.on('input', inputListener);
} else {
$input.on('keyup', keyUpListener);
}
