Client Side People Picker with JSOM in Office 365/SharePoint 2013

Requirement:

In one of the project, I had a requirement to use people picker in Client side HTML which should have same features as SharePoint OOTB people picker provides.

Approach/Solution:

Follow below steps to achieve client side people picker functionality using JSOM.

1. Below mentioned JS files are required to load client side people picker using JSOM. All JS
files are OOTB SharePoint JS files which are available under "_layouts/15" folder in
SharePoint.

- clienttemplates.js
- clientforms.js

- clientpeoplepicker.js

- autofill.js

- sp.js

- sp.runtime.js

- sp.core.js

2. Put reference of all JS files into HTML file for which you want to create Client Side People

Picker.

3. Add below Div tag in your HTML file.
<div id="peoplePickerDiv"></div>

4. Add below code in your custom JS file (custompeoplepicker.js) and also put reference of this file into HTML file.

        // Initialize People Picker.   

 $(document).ready(function() {  

 // Specify the unique ID of the DOM element where the  

 // picker will render.  

 initializePeoplePicker('peoplePickerDiv');  

  });  

 // Render and initialize the client-side People Picker.  

 function initializePeoplePicker(peoplePickerElementId) {  

  // Create a schema to store picker properties, and set the properties.  

  var schema = {};  

  schema['PrincipalAccountType'] = 'User,DL,SecGroup,SPGroup';  

  //This value specifies where you would want to search for the valid values

  schema['SearchPrincipalSource'] = 15;             

  //This value specifies where you would want to resolve for the valid values

  schema['ResolvePrincipalSource'] = 15;  

schema['AllowMultipleValues'] = true;  

  schema['MaximumEntitySuggestions'] = 50;  

  schema['Width'] = '280px';  

  // Render and initialize the picker.  

// Pass the ID of the DOM element that contains the picker, an array of initial   

// PickerEntity objects to set the picker value, and a schema that defines  

// picker properties.    
this.SPClientPeoplePicker_InitStandaloneControlWrapper(
peoplePickerElementId, null, schema);  

                        }

                         // Get user information from client side people picker.

  // Query the picker for user information.

 function getUserInfo() {

  // Get the people picker object from the page.

  var peoplePicker = this.SPClientPeoplePicker.SPClientPeoplePickerDict.peoplePickerDiv_TopSpan;

// Get information about all users.

var users = peoplePicker.GetAllUserInfo();

var userInfo = '';

for (var i = 0; i < users.length; i++) {

var user = users[i];

for (var userProperty in user) {

userInfo += userProperty + ':  ' + user[userProperty] + '<br>';

}

}

// Get user keys.

var keys = peoplePicker.GetAllUserKeys();

// Get the first user's ID by using the login name.

getUserId(users[0].Key);

}

// Get the user ID.

function getUserId(loginName) {

var context = new SP.ClientContext.get_current();

this.user = context.get_web().ensureUser(loginName);

context.load(this.user);

context.executeQueryAsync(

Function.createDelegate(null, ensureUserSuccess),

Function.createDelegate(null, onFail)

);

}

function ensureUserSuccess() {

console.log(this.user.get_id());

}

function onFail(sender, args) {

alert('Query failed. Error: ' + args.get_message());

}

// Below code sets values into client side people picker.

var divPeople = SPClientPeoplePicker.SPClientPeoplePickerDict.PeoplePickerDiv_TopSpan;

PeoplePickerDiv_TopSpan - Specify the unique ID of the DOM element where the picker will render.
var userObj = { 'Key': "sample@sample.com" };
divPeople.AddUnresolvedUser(userObj, true);
