Hello, I'm looking for a way to open an Infowindow by clicking a link "Show on map" from outside a google map in a Visualforce page. Here is my code:

<apex:page sidebar="false" standardController="Lead" recordSetVar="leads">
    <script src="https://ajax.aspnetcdn.com/ajax/jquery/jquery-1.9.1.min.js"></script> 
    <script src="https://ajax.aspnetcdn.com/ajax/jquery.ui/1.10.3/jquery-ui.min.js"></script> 
    <script>
		$( document ).ready(function() {
			var Call = document.getElementsByClassName('MarkerCallback');
			var marker = document.getElementby
			Call.onclick = generateTriggerCallback(marker,"click");
			
			function generateTriggerCallback(object, eventType) {
				return function() {
					google.maps.event.trigger(object, eventType);
				};
			}
		});
	</script>
       <apex:pageBlock title="Selected Leads">

            <apex:form>
            <apex:pageBlockTable value="{!selected}" var="lead">
                <apex:column>
					<apex:inputCheckbox value="{!lead.id}">
					</apex:inputCheckbox>
				</apex:column>
                <apex:column value="{!lead.name}"/>
                <apex:column value="{!lead.city__c}"/>
                <apex:column value="{!lead.state__c}"/> 
                <apex:column>
					<apex:outputlink value="http://www.maps.google.com/?q={!lead.city__c}+{!lead.street__c}+{!lead.number__c}+{!lead.State__c}" target="_blank">
						Open on Google Maps
					</apex:outputlink>
				</apex:column>
				<apex:column><a href="#" id="{!lead.id}" class="MarkerCallback">Show on map</a>
                </apex:column>
            </apex:pageBlockTable>
            </apex:form>
        </apex:pageBlock>
        <apex:pageBlock>

                    </apex:mapMarker>

                    <!-- /> -->
                </apex:repeat>
