Question

我的网页上有Bing地图，我想检测用户在窗口中点击的时间。但是，我不希望检测用户何时拖动地图（这也会生成“点击”事件）。只获得“纯粹”点击事件的最佳方式是什么？

Answer 1

我的解决方案最终是手动检查点击位置是否接近鼠标被按下的位置。

Microsoft.Maps.Events.addHandler(map, "click", clickHandler);
Microsoft.Maps.Events.addHandler(map, "mousedown", function(me) { lastMouseDownPoint = new Microsoft.Maps.Point(me.getX(), me.getY());});


function clickHandler(mouseEventArgs){
  var point = new Microsoft.Maps.Point(mouseEventArgs.getX(), mouseEventArgs.getY());

  //Drag detection

  // Edited since the comma is incorrect, should be a plus as per pythagorean theorem
  var dist = Math.sqrt(Math.pow(point.x-lastMouseDownPoint.x,2) + Math.pow(point.y-lastMouseDownPoint.y,2));
  if(dist > 5) {
    // We call this a drag
    return;
  }

// We have a "pure" click and can process it

}

Answer 2

很简单：

Microsoft.Maps.Events.addHandler(map, 'click', onClick);

function onClick(e) {
    if (e.mouseMoved === false && e.isPrimary === true) {
        // Left click not being a drag
        ...
    }
}

mouseMoved在拖放时为true，否则为false。
