Question

以下脚本将球从盒子中的一个位置移动到另一个位置。

我想收集在此框中单击鼠标的位置的坐标，并将onclick上方的X和Y坐标转换为PHP变量，以便一些其他PHP代码可以处理此问题。

请问如何完成？

<!DOCTYPE html>
<html>

<head>
<title>Move to Click Position</title>
<style type="text/css">
body {
    background-color: #FFF;
    margin: 30px;
    margin-top: 10px;
}
#contentContainer {
    width: 550px;
    height: 350px;
    border: 5px black solid;
    overflow: hidden;
    background-color: #F2F2F2;
    cursor: pointer;
}
#thing {
    position: relative;
    left: 50px;
    top: 50px;
    transition: left .5s ease-in, top .5s ease-in;
}
</style>
</head>

<body>
<div id="contentContainer">
    <img id="thing" src="//www.kirupa.com/images/smiley_red.png">
</div>

<script src="//www.kirupa.com/prefixfree.min.js"></script>
<script>
var theThing = document.querySelector("#thing");
var container = document.querySelector("#contentContainer");

container.addEventListener("click", getClickPosition, false);

function getClickPosition(e) {
    var parentPosition = getPosition(e.currentTarget);
    var xPosition = e.clientX - parentPosition.x - (theThing.clientWidth / 2);
    var yPosition = e.clientY - parentPosition.y - (theThing.clientHeight / 2);

    theThing.style.left = xPosition + "px";
    theThing.style.top = yPosition + "px";
}

// Helper function to get an element's exact position
function getPosition(el) {
  var xPos = 0;
  var yPos = 0;

  while (el) {
    if (el.tagName == "BODY") {
      // deal with browser quirks with body/window/document and page scroll
      var xScroll = el.scrollLeft || document.documentElement.scrollLeft;
      var yScroll = el.scrollTop || document.documentElement.scrollTop;

      xPos += (el.offsetLeft - xScroll + el.clientLeft);
      yPos += (el.offsetTop - yScroll + el.clientTop);
    } else {
      // for all other non-BODY elements
      xPos += (el.offsetLeft - el.scrollLeft + el.clientLeft);
      yPos += (el.offsetTop - el.scrollTop + el.clientTop);
    }

    el = el.offsetParent;
  }
  return {
    x: xPos,
    y: yPos
  };
}
</script>
</body>
</html>

然后我可以在其他脚本中对其进行处理。

如果有人可以解释如何实现这一目标，将不胜感激。

谢谢

    <input type=”hidden” value="" id="myField1" name="myField1">
    <input type=”hidden” value="" id="myField2" name="myField2">

    <input type="submit" value="Submit">

    </form>
    </body>
    </html>
