跟踪鼠标位置

我希望跟踪鼠标光标的位置,周期性地每t秒。因此,从本质上讲,当一个页面加载时,这个跟踪器应该开始,(比如说)每100毫秒,我应该得到posX和posY的新值,并将其打印到表单中。

我尝试了下面的代码-但值不会刷新-只有posX和posY的初始值显示在表单框中。有什么办法能让它运行起来吗?

<html>
<head>
<title> Track Mouse </title>
<script type="text/javascript">
function mouse_position()
{
    var e = window.event;

    var posX = e.clientX;
    var posY = e.clientY;

    document.Form1.posx.value = posX;
    document.Form1.posy.value = posY;

    var t = setTimeout(mouse_position,100);

}
</script>

</head>

<body onload="mouse_position()">
<form name="Form1">
POSX: <input type="text" name="posx"><br>
POSY: <input type="text" name="posy"><br>
</form>
</body>
</html>

这是追踪鼠标位置的最简单方法

Html

<body id="mouse-position" ></body>

js

document.querySelector('#mouse-position').addEventListener('mousemove', (e) => {
        console.log("mouse move X: ", e.clientX);
        console.log("mouse move X: ", e.screenX);


    }, );

在我看来,少即是多。

查看onmousemove事件以获得有关该事件的更多信息。

每次鼠标根据水平坐标和垂直坐标移动时,都会有一个新的posX和posY值。

<!DOCTYPE html>
    <html>
    <head>
      <meta charset="utf-8">
      <title>Example Mouse Tracker</title>
      <style>    
        body {height: 3000px;}
        .dot {width: 2px;height: 2px;background-color: black;position: absolute;}
      </style>
    </head>
    <body>
    <p>Mouse tracker</p>
    <script>
    onmousemove = function(e){
        //Logging purposes
        console.log("mouse location:", e.clientX, e.clientY);

        //meat and potatoes of the snippet
        var pos = e;
        var dot;
        dot = document.createElement('div');
        dot.className = "dot";
        dot.style.left = pos.x + "px";
        dot.style.top = pos.y + "px";
        document.body.appendChild(dot);
    }      
    </script>
    </body>
    </html>

最近,我们必须找到当前的x,y位置,以枚举光标所悬停的元素,而不依赖于z-index。我们最终只是附加了一个鼠标移动事件监听器到文档,例如,

功能findElements(e) ( var els =文档。clientX, clientY); 和els一起做酷的东西 游戏机。log (els); return; ) 文档。addEventListener (mousemove”、“findElements);

我认为我们想太多了,

函数mouse_position (e) { / /做东西 } <身体onmousemove = " mouse_position(事件)" > < /身体>

document.addEventListener('mousemove', (event) => { document.getElementById("line").style.top = event.clientY - 10 + 'px'; document.getElementById("lineY").style.left = event.clientX - 10 + 'px'; document.getElementById("pos").style.top = (event.clientY - 60) + 'px'; document.getElementById("pos").style.left = (event.clientX - 60) + 'px'; }); body { position: relative; height: auto; min-height: 100% !important; background-color: lightblue; } h1 { color: white; text-align: center; } p { font-family: verdana; font-size: 20px; } .abs { position: relative; } .lineY { display: flex; position: relative; left: 0px; background-color: black; width: 2px; height: 100vh; min-height: 100% } .line { display: flex; position: relative; background-color: black; min-height: 2px; width: 100%; } .circle { display: flex; position: absolute; left: 0px; top: 0px; } <div class='line' id="line"></div> <div class='lineY' id="lineY"></div> <svg height="100" width="100" id="pos" class="circle"> <circle cx="50" cy="50" r="40" stroke="black" stroke-width="3" fill="transparent" /> </svg>
