How can I bind click event to custom overlay with

问题:

I've already subclass my overlay object under the instruction of google document, and my onAdd() function is listed below:

MyOverlay.onAdd() {
    var div_parent = document.createElement("DIV");
    var div_child = document.createElement("DIV");
    div_child.innerHTML = "Click Me";
    div_parent.appendChild( div_child );
    this.getPanes().overlayLayer.appendChild(div_parent);
    var this = that;
    google.maps.event.addDomListener( div_parent, 'click', function(){
        google.maps.event.trigger(that, 'click'); // from [http://stackoverflow.com/questions/3361823/make-custom-overlay-clickable-google-maps-api-v3]
        alert("Clicked");
    } );

}

My code can work well ONLY in IE, but in Firefox and Chrome, the click event will not be triggered anymore.

So how to solve the problem?

回答1:

Instead of using overlayLayer mapPanes, you should use overlayMouseTarget.

I know this is an old post, but if you were wondering, here is the solution:

In your code above, you need to change the overlay function from:

this.getPanes().overlayLayer.appendChild(div_parent);

to:

this.getPanes().overlayMouseTarget.appendChild(div_parent);

Also note although your click events will be captured on desktop even if you use overlay pane, for touch events to work, mouse target pane is necessary.
