How to pass map from lightening Component to apex Controller.

Controller

var dataMap = component.get("v.values");  
      //  console.log(accountId) ;
        var accountList = [];       
        for ( var key in dataMap ) {
            accountList.push({key: key, value:dataMap[key]});
        }
        console.log(accountList) ;        
        var action = component.get("c.updateSortOrder");
        // console.log(accountList) ;
        action.setParams({
            "updateTasksMap":accountList
        });  



AuraEnabled

hi,

 you can take references from the below code.

<aura:component controller="Your_Controller">
    <aura:attribute name="theMap" type="Map" default="{}"/>
    <aura:handler name="init" value="{!this}" action="{!c.doInit}" />
</aura:component>
Controller code:

({
    doInit : function(component, event, helper) {
        var action = component.get("c.SaveBatchDet");
        var theMap = component.get("v.theMap");
        //add some params
        theMap["key1"]="test1,test2,test6";
        theMap["key2"]="test3,test4,test5";
        action.setParams({
           "RowIndex": theMap
        });
        action.setCallback(this, function(result) {} );
        $A.enqueueAction(action);
    }
})

Apex :

@AuraEnabled
public static list<batch__c> SaveBatchDet(map<string,list<batch__c>> RowIndex){
         system.debug('RowIndex'+RowIndex);
}
