如何在没有鼠标事件的情况下获得 jQuery 中的鼠标位置？

I don't believe there's a way to query the mouse position, but you can use a mousemove handler that just stores the information away, so you can query the stored information.

jQuery(function($) {
var currentMousePos = { x: -1, y: -1 };
$(document).mousemove(function(event) {
currentMousePos.x = event.pageX;
currentMousePos.y = event.pageY;
});


// ELSEWHERE, your code that needs to know the mouse position without an event
if (currentMousePos.x < 10) {
// ....
}
});

But almost all code, other than setTimeout code and such, runs in response to an event, and most events provide the mouse position. So your code that needs to know where the mouse is probably already has access to that information...

You can't read mouse position in jQuery without using an event. Note firstly that the event.pageX and event.pageY properties exists on any event, so you could do:

$('#myEl').click(function(e) {
console.log(e.pageX);
});

Your other option is to use a closure to give your whole code access to a variable that is updated by a mousemove handler:

var mouseX, mouseY;
$(document).mousemove(function(e) {
mouseX = e.pageX;
mouseY = e.pageY;
}).mouseover(); // call the handler immediately


// do something with mouseX and mouseY

I used this method:

$(document).mousemove(function(e) {
window.x = e.pageX;
window.y = e.pageY;
});


function show_popup(str) {
$("#popup_content").html(str);
$("#popup").fadeIn("fast");
$("#popup").css("top", y);
$("#popup").css("left", x);
}

In this way I'll always have the distance from the top saved in y and the distance from the left saved in x.

Moreover, mousemove events are not triggered if you perform drag'n'drop over a browser window. To track mouse coordinates during drag'n'drop you should attach handler for document.ondragover event and use it's originalEvent property.

Example:

var globalDragOver = function (e)
{
var original = e.originalEvent;
if (original)
{
window.x = original.pageX;
window.y = original.pageY;
}
}

I came across this, tot it would be nice to share...

What do you guys think?

$(document).ready(function() {
window.mousemove = function(e) {
p = $(e).position();  //remember $(e) - could be any html tag also..
left = e.left;        //retrieving the left position of the div...
top = e.top;          //get the top position of the div...
}
});

and boom, there we have it..

use window.event - it contains last event and as any event contains pageX, pageY etc. Works for Chrome, Safari, IE but not FF.

var CurrentMouseXPostion;
var CurrentMouseYPostion;


$(document).mousemove(function(event) {
CurrentMouseXPostion = event.pageX;
CurrentMouseYPostion = event.pageY;
});

Make an eventListener on the main object , in my case the document object, to get the mouse coords every frame and store them in global variables, and like that you can read mouse Y & Z whenever youlike , wherever you like.
