在firefox 41中获取鼠标坐标

Question

我试图根据鼠标坐标拖放一个元素。它在chrome和IE中运行良好，但在firefox中不能运行。

下面是我尝试过的:

function createShape(event)
{
    var stageContainer = $(".mainArea");
    var stageOffset = stageContainer.offset();
    clientX = event.clientX;
    clientY = event.clientY;
    offsetX = stageOffset.left;
    offsetY = stageOffset.top;
    x = clientX - offsetX; // works in chrome and IE
    y = clientY - offsetY; // works in chrome and IE
    //Firefox
    var offX = (event.offsetX || event.pageX - $(event.target).offset().left);
    var offY = (event.offsetY || event.pageY - $(event.target).offset().top);
    layerX = event.layerX;
    layerY = event.layerX;
    screenX = event.screenX;
    screenY = event.screenY;
    pageX = event.pageX;
    pageY = event.pageY;
    e = jQuery.event.fix(event);
    var target = event.target || event.srcElement;
    //Right now this is working but x and y are not exactly correct
    x = screenX + offsetX
    y = screenY + offsetY

不支持firefox

ClientXY return 0,0
LayerXY return largest number like 173839,173839
pageX and pageY returns 0,0
element.offset().left returns 70 always
element.offset().top returns 63 always
createRect(x, y); // creating element on dragend with x and y coordinates on dragend

}

我如何获得鼠标拖动结束坐标?

遗憾的是，Firefox没有在drag事件上填充pageX和pageY属性。相关的bug报告从2009年就公开了，而且看起来不会很快得到修复。常见的解决方案是侦听父元素上的dragover事件(尽管很难检测到哪个元素正在被拖动)或以其他方式检测被拖动元素的位置。
