I have an apex method that returns a result in this form Map<String, List<Map<String,String>>> And I'd like to use this result localy to generate two dependent picklist. How can I call this method from my javascript code ? I haven't created the JS function yet.. Can someone tell me how to proceed ?

If you are using VF page then you can call it using action:function.

Apex method:

    public PageReference getMyMethod(){
    ....
    return null;
}

Visualforce page action function:

<apex:actionFunction action="{!MyMethod}" name="myFunction" />

actionFunction works like a javascript function, so you can call it from anywhere at your page like this:

<apex:inputField value="{!something}" onchange="myFunction()" />

and if you want call it from JavaScript button pls see this link

  • Thank you for your answer i understand now how to do the call.. In my JS function how can I put the result of my apex method in a variable ? Is it possible to do something like var res = myApexMethod(); ? – Joey Pablo Nov 12 '15 at 12:55
  • I have tried that and I get res = false ? i don't understand why.. – Joey Pablo Nov 12 '15 at 13:03
  • You can not assign the value like this. If you want to display it on VF page then you need to create getter method. which would be something like this -- getMyMethod, get keyword with your method name, so here myMethod will hold value and you can use on the page. – MIX DML Nov 12 '15 at 13:22
  • Can you explain more please ? should I create a getter method that returns a pageReference ? – Joey Pablo Nov 12 '15 at 13:36
