Displaying Static Resources Image in Lightning Component

To reference a specific resource in component markup, we can use $Resource.resourceName within an expression. resourceName is the Name of the static resource. In a managed packaged, the resource name must include the package namespace prefix, like $Resource.yourNamespace__resourceName.

Sample Code:

    <!-- Stand-alone static resources image file-->
    <img src="{!$Resource.resourceName}"/>
    <!-- Stand-alone static resources image file with Namespace-->
    <img src="{!$Resource.yourNamespace__resourceName}"/>
    <!-- Asset from an archive static resource image file-->
    <img src="{!$Resource.resourceName + '/assets/images/logo.png'}"/>
    <!-- Asset from an archive static resource image file with Namespace-->
    <img src="{!$Resource.yourNamespace__resourceName + '/assets/images/logo.png'}"/>

Dynamic Getting sObject Picklist Values on Lightning Component

In this example we will fetch Picklist field “Industry” values from “Account” object and set in ui:inputSelect on Lightning Component.

Apex Class:

public class GetPicklistValuesController {
    public static List <String> getPicklistValues(sObject obj, String fld) {
        List <String> pList = new list <String>();
        //Get the object type of the SObject.
        Schema.sObjectType objType = obj.getSObjectType();

        //Describe the SObject using its object type.
        Schema.DescribeSObjectResult objDescribe = objType.getDescribe();

        //Get a map of fields for the SObject
        Map<String, Schema.SObjectField> fieldMap = objDescribe.fields.getMap();

        //Get the list of picklist values for this field.
        List<Schema.PicklistEntry > values = fieldMap.get(fld).getDescribe().getPickListValues();

        //Add these values to the selectoption list.
        for (Schema.PicklistEntry a: values) {
        return pList;


<aura:component controller="GetPicklistValuesController" access="global" implements="force:appHostable">
    <aura:attribute name="objInfo" type="account" default="{sobjectType : 'Account'}" />
    <aura:handler name="init" value="{!this}" action="{!c.doInit}"/>    
    <div class="slds-form-element">
        <label class="slds-form-element__label" for="select-01">Select Industry</label>
        <div class="slds-select_container">
            <ui:inputSelect  aura:id="accIndustry" class="slds-select"  change="{!c.onPicklistChange}"/>

Component Helper:

    fetchPickListVal: function(component, fieldName, elementId) {
        var action = component.get("c.getPicklistValues");
            "obj": component.get("v.objInfo"),
            "fld": fieldName
        var opts = [];
        action.setCallback(this, function(response) {
            var state = response.getState();
            if (state == "SUCCESS") {
                var allValues = response.getReturnValue();
                    class: "optionClass",
                    label: "--- None ---",
                    value: ""
                for (var i = 0; i < allValues.length; i++) {
                        class: "optionClass",
                        label: allValues[i],
                        value: allValues[i]
                component.find(elementId).set("v.options", opts);

Component Controller:

    doInit: function(component, event, helper) {
        helper.fetchPickListVal(component, 'Industry', 'accIndustry');
    onPicklistChange: function(component, event, helper) {
        //get the value of select option

Lightning App:

    <c:TestComponent />
