jq obtains the current position coordinates of the mouse in real time, which can be achieved through the two attribute methods of jQuery event.pageX and event.pageY. jQuery event.pageX can be used to find the mouse position relative to the left edge of the document, and event.pageY can be used to find the mouse position relative to the top edge of the document.

Now we will introduce to you the jq method of obtaining the position coordinates of the mouse based on specific code examples.

The code example is as follows:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="utf-8">
    <title>jq获取鼠标位置坐标示例</title>
    <style type="text/css">
 *{
            margin: 0;
 }
        html, body{
            height:100%;
 }
    </style>
    <script src="https://code.jquery.com/jquery-1.12.4.min.js"></script>
    <script type="text/javascript">
 $(function() {
            $("body").mousemove(function(event){
                var relPageCoords = "(" + event.pageX + "," + event.pageY + ")";
 $(".mouse-cords").text(relPageCoords);
 });
 });
 </script>
</head>
<body>
<p>当前鼠标的坐标为： <strong class="mouse-cords"></strong></p>
</body>
</html>
