Salesforce Pagination Lightning Component

Hi All,
I have created a Pagination component which can be used as Lightning Component. This is very easy to setup and configure. You simply need to drag it in app builder and configure by giving objectname, fieldnames and the title of the pagination. By default it will fetch contact object and its by default giving fields.


For more information, watch it here -:

Here is the code:- 

Apex Controller:- 
public class PaginationController{ @AuraEnabled public static String getContacts(String objectName,String fieldName){ List<sObject> mylist = new List<sObject>(); String query = 'Select '; string fieldNames = queryableField(objectName, fieldName); if(string.isNotBlank(objectName) && string.isNotBlank(fieldNames)){ if(!new set<string>(new List<String>(fieldNames.split(','))).contains('Id')) query +='Id, '; query += fieldNames +' from '+objectName; }else if(string.isNotBlank(fieldNames)){ if(!new set<string>(new List<String>(fieldNames.split(','))).contains('Id')) query +='Id, '; query += fieldNames +' from contact'; } if(query != null) mylist = Database.query(query); if(mylist != null && mylist.size() > 0){ Map<String, Schema.SObjectField> FieldMap = Schema.getGlobalDescribe().get(string.valueOf(mylist.get(0).getSObjectType())).getDescribe().fields.getMap(); String jSon='['; String coma=''; List<string> field = fieldNames.split(','); for(sObject con : mylist) { jSon += '['; Integer i=0; for(string f : field){ if(i==0){ jSon += coma + '"<a target=\'_blank\' class=\'showDetail\' id=\''+con.get('Id')+'\' >' +con.get(f)+ '</a>",'; } else { jSon += coma + '"'+con.get(f)+'",'; } i++; } jSon += '],'; } jSon+=']'; return jSon; } else { return null; } } //function for return valid fields on basis of object and fields string. @AuraEnabled public static string queryableField(string objectString, string fieldString){ if((string.isBlank(objectString) && string.isBlank(fieldString)) || (string.isNotBlank(objectString) && string.isBlank(fieldString)) || string.isBlank(fieldString) ) return null; set<string> objectName = new set<string>(); for(string obj : Schema.getGlobalDescribe().keyset()) objectName.add(obj.toLowercase()); if(!objectName.contains(objectString.toLowercase())) return null; set<string> allFields = new set<string>(); set<string> validField = new set<string>(); Map<String, Schema.SObjectField> FieldMap; if(string.isNotBlank(objectString)) FieldMap = Schema.getGlobalDescribe().get(objectString).getDescribe().fields.getMap(); else FieldMap = Schema.getGlobalDescribe().get('contact').getDescribe().fields.getMap(); for(string field : FieldMap.keySet()){ allFields.add(FieldMap.get(field).getDescribe().getName().toLowercase()); } for(string f : fieldString.split(',')){ if(string.isNotBlank(f)){ if(allFields.contains(f.toLowercase())) validField.add(f.capitalize()); } } return string.join(new List<string>(validField),','); } }
 
Aura Controller:-  
({ doInit : function(component, event, helper) { var dataSet; var columns; var action = component.get("c.getContacts"); var action2 = component.get("c.queryableField"); var objectName = component.get("v.objectName"); var fieldName = component.get("v.fieldName"); var title = component.get("v.title"); component.set("v.title",title); var fields; var splitfileds; action.setParams({ "objectName":objectName, "fieldName":fieldName }) ; action2.setParams({ "objectString":objectName, "fieldString":fieldName }) ; var self = this; action2.setCallback(this,function(response){ var state = response.getState(); if(component.isValid() && state === "SUCCESS"){ fields = response.getReturnValue().split(","); var jSon='['; var coma=''; for(var i=0;i<fields.length;i++) { jSon+=coma+'{title:"'+fields[i]+'"}'; coma=','; } jSon+=']'; splitfileds = eval(jSon); } }); $A.enqueueAction(action2); action.setCallback(this,function(response){ var state = response.getState(); if(component.isValid() && state === "SUCCESS") { dataSet = eval(response.getReturnValue()); $(function(){ /* initiate the plugin */ $(window).resize(function(){ if ($(window).width() <= 700) { $('.container ').css({"overflow-x":"scroll","width":"100%"}); } else{ $('.container ').css({"overflow-x":"none","width":"100%"}); } }); var table = $('#example').DataTable({ data: dataSet, columns:splitfileds, "fnDrawCallback": function( oSettings ) { $('.showDetail').css({"cursor":"pointer","text-decoration":"none"}); $('.showDetail').click(function(){ var recordId = $(this).attr('id'); helper.navigateToDetailsView(recordId); }); } }); }); } }); $A.enqueueAction(action); } })

Aura Component:-
<aura:component controller="PaginationController" implements="flexipage:availableForAllPageTypes"> <ltng:require styles="/resource/bootstrap/css/datatable.css, /resource/bootstrap/css/mycss.css" scripts="/resource/bootstrap/js/jquery.js, /resource/bootstrap/js/datatable.min.js" afterScriptsLoaded="{!c.doInit}"/> <aura:attribute name="objectName" type="String" default="contact"/> <aura:attribute name="fieldName" type="String" default="name,id,email"/> <aura:attribute name="title" type="String" default="Pagination Table"/> <div class="container"> <h2>{!v.title}</h2> <br/> <table class="table table-bordered display" id="example"> </table> </div> </aura:component>

Aura Helper:-
({ navigateToDetailsView : function(accountId) { var event = $A.get("e.force:navigateToSObject"); event.setParams({ "recordId": accountId }); event.fire(); } })

Aura Application:-
<aura:application > <div class="container"> <c:dynamicPaginationForm /> </div> </aura:application>

Aura Design:- 
<design:component> <design:attribute name="objectName" label="Object Name"/> <design:attribute name="fieldName" label="Field Name"/> <design:attribute name="title" label="Title"/> </design:component>

  9. Hi Sakib Beig

    Can you please attached the Static Resources ZIP file; because the download link is taken to your dev org, we don't have any credential for that.

    Without those Static Resources I can't run this APP.

    Appreciate your quick response.

    Thanks
