I'm trying to make some custom Google maps info windows, but I'm getting the issue where markers underneath my custom info window is clickable through the info window.
Here's an example (basically straight from googles example here)

* under the marker, opens quicker, and has flexible styling.

You can see I'm making two markers, one just to the north east of the other. Click the bottom one then observe how the other marker is clickable through the marker (right near the 'W').
How can I fix this?! I've tried altering the z-index but that didn't seem to help.
This is using api v3 btw.
For posterity, you want to disable a bunch of events on the marker pop-up dom, this was the prescribed method, even though it feels like overkill. You could alternatively cycle through all the markers present apart from the one clicked and disable clicking on them (actually that's probably a better solution in hindsight). Depends on how many markers you have perhaps, I had a lot.
Something like this (transcribed here without testing from my coffeescript so...)
// All in a google.maps.OverlayView subclass.
...
this.listeners = new Array(); // save listeners for unbinding later
...
this.cancelEvents = function(){
events = ['mousedown', 'mousemove', 'mouseover',
'mouseout', 'mouseup', 'mousewheel',
'DOMMouseScroll', 'touchstart', 'touchend',
'touchmove', 'dblclick', 'contextmenu'];
// Note, don't disable 'click' if you want to be able to click links in the dom. Some things we're disabling here will can effect how your user might interact with the popup (double click to select text etc)
for(var i = 0; i < events.length; i++){
var event = events[i];
this.listeners.push(
google.maps.event.addDomListener(
this.popup_dom_element,
event,
function(ev){
e.cancelBubble = true;
if(e.stopPropagation){
e.stopPropagation();
}
}
);
);
}
}
this.onAdd = function (){
// build your html popup
var html_code = "...";
// easy way to get a dom element but probably over kill if its your only JQ
this.popup_dom_element = $(html_code);
this.cancelEvents();
}
this.onRemove = function(){
// any other removal code you have
...
for(var i = 0; i < this.listeners.length; i++){
// remove our event listeners
google.maps.event.removeListener(this.listeners[i]);
}
}
