[SalesForce] Access apex Map in Javascript

I'm trying to access a the apex Map named "resultsMap" with javascript, I would like to get contact last name using contact id.

public class AccessMapJS {
    public Map<ID, Contact> resultsMap{get;set;} 
    public String JsonMap{get;set;} 

    public AccessMapJS(){
        resultsMap = new Map<ID, Contact>([SELECT Id, LastName FROM Contact limit 3]);
        JsonMap=JSON.serialize(resultsMap); 
    }
}

VF page:

<apex:page controller="AccessMapJS" >
<script>
// Access here resultsMap: get contact last name using contact id


</script>
  {!resultsMap}
</apex:page>

Do you know hoe to accomplish that ?
Thanks in advantage for any advice.

Your controller is fine.

You can get it in via javascript if thats your preference:

var contactMap = JSON.parse('{!JsonMap}');
var lastname = contactMap['003....'].LastName;

The children records will be contained within standard List collections under the parent object record.

Enhancing your much-too-genericized code sample:

Map<Id, Account> AcctOppCustomObjectMap = new Map<Id, Account>([SELECT Id
                                                                    ,(SELECT xxx 
                                                                        FROM xxx__r)
                                                                    ,(SELECT yyy 
                                                                        FROM yyy__r) 
                                                                FROM Account
                                                                WHERE Id IN :idSet]);

List<yyy__c> yThingsToUpdate = new List<yyy__c>();

for (Id accountId : AcctOppCustomObjectMap.keyset()) {
    Account acct = AcctOppCustomObjectMap.get(accountId);

    // the acct reference will have child lists for your subqueries
    // they will not be null, but they could be empty lists
    List<xxx__c> xxxList = acct.xxx__r;
    List<yyy__c> yyyList = acct.yyy__r;

    // iteration of the child records possible now using these two lists
    for (xxx__c xThing : xxxList) {
        for (yyy__c yThing : yyyList) {
            if (xThing.value == yThing.value) {
                // create your relationship and 
                // add to a list for bulk update / insert
                yThingsToUpdate.add(new yyy__c(Id = yThing.Id
                                                   , xxx__c = xThing.Id));

                break; // exit the for loop on the first match if desired
            }
        }
    }
}


if (!yThingsToUpdate.isEmpty()) {
    update yThingsToUpdate;
}

I would probably iterate each child list just once each to create maps of the contents by a desired key so that I could perform a Map.get() instead of repeatedly iterating lists to find the other child record to compare against. Your code sample needs more specific information in it.

Repeated iteration of the yyy list within the xxx list will limit your ability to process records since these will use script statements to iterate and match the records.

[SalesForce] Apex Page Component set Language via Javascript

You can instead use global variables for your requirements

$CurrentPage.parameters.parameterName

so if your parameter name is lang

you can use

<apex:page language="{!$CurrentPage.parameters.lang}" applyHtmlTag="false" showHeader="false" docType="html-5.0" cache="false" >

Once you access from URL i think the global variable will be automatically decoded.
