Is it possible for me to identify a specific part of the screen with jquery and javascript? For example when passing by height y does it perform for me a function? I imagine something like this:
var minha_altura = $(window).height();
var altura = 400;
if(minha_altura > 400)
{
//faz algo
}
Is the concept correct and does it really work?
You can create an event in the window to detect the movement of the mouse and thus the pageX / Y of it.
window.addEventListener('mousemove', function(event) {
if(event.pageY > 400) {
//{...}
} else {
//{...}
}
});
See an example:
window.addEventListener('mousemove', function(e) {
document.body.innerHTML = '<p> PageY:'+e.pageY+'</p><p> PageX:'+e.pageX+'</p>';
});
