在Google Map API v3中如何区分鼠标左键和右键点击mousedown事件

问题描述

Google Map API v3的mousedown事件在左右两侧被触发，我怎样才能确定它是右键单击还是左键单击。

我是新的谷歌地图API，我到现在为止使用虚拟地球API，我可以区分鼠标左键和右键点击，如e.leftMouseButton返回true，如果它是左键点击。

对于右键点击事件，您可以通过这种方式捕获右键点击事件：

  google.maps.event.addListener（map，rightclick，function（event）{
 / *做点右键点击* / 
 }）;

要区分使用 mousedown 事件，您可以使用 event.which 参数。但为此，应该将处理程序添加到DOM元素（画布）中，因为Google API不会在事件对象中提供 选项。

  var c = document.getElementById（'map-canvas'）; 
 google.maps.event.addDomListener（c，mousedown，function（e）{
 if（e.which === 1）{
 $（＃click））。 text（Left click）; 
} else if（e.which === 2）{
 $（＃click）。text（Middle click）; 
} （e.which === 3）{
 $（＃click）。text（right click）; 
} 
}）; 
  

The mousedown event of Google Map API v3 gets fired on left and right click both, how can I identify whether it is right click or left click.

I am new to Google Map API, I was using Virtual Earth API until now, where I was able to distinguish between left and right mouse click on mouse down like e.leftMouseButton returns true if it is left click.

解决方案

Instead of mousedown use simply click.

For right click event you can catch rightclick event this way:

google.maps.event.addListener(map, "rightclick", function(event) {
  /* do something on right click */
});

To distinguish what button was pressed using mousedown event you can use event.which parameter. But for that, the handler should be added to DOM element (canvas), since Google API doesn't provide which option in event object.

var c = document.getElementById('map-canvas');
google.maps.event.addDomListener(c, "mousedown", function (e) {
    if (e.which === 1) {
        $("#click").text("Left click");
    } else if (e.which === 2) {
        $("#click").text("Middle click");
    } else if (e.which === 3) {
        $("#click").text("Right click");
    }
});
