I am attempting to trigger a mouseup event following a mousedown action

Question

I am attempting to trigger a mouseup event following a mousedown action

elements[0].onmousedown = function(){
      console.log('screen clicked.');
      triggerMouseUp();
};

I just need to incorporate a function in my code that simulates mouseup event, even when the user is still holding down the click button.

elements[0] represents the entire page, so every click will be detected.

javascript html css angularjs

Answer №1

You simply need to initiate the onmouseup event by calling it directly...

elements[0].onmousedown = function(){
      console.log('mouse button pressed.');

      elements[0].onmouseup();
};

Remember that releasing the mouse button will trigger the mouseup event again, unless handled in the onmouseup() function.

Could it be that instead of simulating a mouseup event, you actually intend to execute the function associated with the mouseup event?

var onMouseUp = function() { 
 /* perform an action */  
};

var onMouseDown = function() { 
 /* perform an action */ 
 onMouseUp.apply(this,arguments); 
};

elements[0].onmousedown = onMouseDown;
elements[0].onmouseup = onMouseUp;

When the body is clicked, it triggers a mouseup event using jQuery. Then, when the mouse is released, it logs information about the event.

Alternatively, you can refer to this answer on Stack Overflow:

The methods mentioned above rely on how the listener is set up: jQuery, element property.

If you prefer a reliable method that works regardless of the event setup, consider using How can I trigger a JavaScript event click

elements[0].onmousedown = function(){
    fireEvent(elements[0], 'onmouseup');
};

Keep in mind that it may be more beneficial to encapsulate the mouseup handler's behavior into a function that can be easily called. Triggering handlers can be problematic as you might inadvertently trigger other events. For instance:

function doSomethingOnMouseUp() {
    console.log('something on mouse up');
}

elements[0].onmousedown = function(){
    doSomething();
    doSomethingOnMouseUp();
};

elements[0].onmouseup = doSomethingOnMouseUp;
