Use a custom sidebar to lock form fields

This sample shows how to add a custom sidebar to the viewer with a custom UI that provides control over which users can fill a form, and for which users the form fields will be locked.

window.onload = function () { //DsPdfViewer.LicenseKey = "***key***"; var viewer; var React; var ReactDOM; var initialAccessTable = null; function applyAccess(selectedUserName, access) { console.log('Apply access for ' + selectedUserName + ': ' + access + ', current user name:' + viewer.currentUserName); if (selectedUserName === viewer.currentUserName) { viewer.findAnnotation(20, // 20 - AnnotationTypeCode.WIDGET { findField: 'annotationType', pageNumberConstraint: 1, findAll: true }).then(function (annotationsDataArr) { viewer.updateAnnotations(0, annotationsDataArr.map(function (data) { if (access === 'LockAll') { data.annotation.locked = true; } else if (access === 'LockFirstName' && data.annotation.fieldName === "FirstName") { data.annotation.locked = true; } else if (access === 'LockLastName' && data.annotation.fieldName === "LastName") { data.annotation.locked = true; } else { data.annotation.locked = false; } return data.annotation; })); }); } } function getInitialAccessTable(users) { if (!initialAccessTable) { initialAccessTable = {}; for (var i = 0; i < users.length;
