How to pass the picklist value to javascript controller in Salesforce Lightning?

Hi Anurag,

You should create schema for the picklist and call this method from component using aura init. this will fetch picklist value on loading the component.

public static List<String> getLeadStatus(){
List<String> options = new List<String>();
Schema.DescribeFieldResult fieldResult = lead.status.getDescribe();
List<Schema.PicklistEntry> ple = fieldResult.getPicklistValues();
for (Schema.PicklistEntry f: ple) {
options.add(f.getLabel());
}return options;}

Java script controller code -

doInit : function(component, event, helper) {
var action = component.get("c.getLeadStatus");
var inputsel = component.find("InputSelectDynamic");
var opts=[];
action.setCallback(this, function(a) {
for(var i=0;i< a.getReturnValue().length;i++){
opts.push({"class": "optionClass", label: a.getReturnValue()[i], value: a.getReturnValue()[i]});
}
inputsel.set("v.options", opts); });
$A.enqueueAction(action);
}

For picklist -

<ui:inputSelect label="Status" class="dynamic" aura:id="InputSelectDynamic" value="{!v.leadObj.Status}"   required="true"/>
