![]() For this reason, the UI will have an Add option, and a dropdown search filter. To keep it simple, once a technique gets introduced, I’ll move on to the next technique so as not to belabor the point. In this take, I’ll showcase all the latest JavaScript features, using a UI that features author data with a grid and a search filter. Options normally reserved to front-end frameworks, such as a component-based approach, is now feasible in plain old JavaScript. Developers who want to take advantage of the latest features have the option of going framework-less with less hassle. To learn more about SurveyJS Project, visit our website: surveyjs.io.JavaScript in the browser has evolved. (Requires a commercial developer license). SurveyJS Export to PDF - exports survey responses as PDF files.SurveyJS Analytics Pack - displays survey responses in a dashboard. ![]() SurveyJS Creator - a survey / form builder component that you can embed into your websites.(Available for free under the MIT license). SurveyJS Library - embeds and runs surveys on your websites.SurveyJS Project includes four open-source JavaScript Libraries: Leave a comment below if you want us to continue implementing the service in our future articles. Missing capabilities include showing surveys to end users, gathering survey responses, and presenting them in a table or dashboard. You have learnt how to add our Survey Creator component into your React application and save survey JSON definitions in a database. Update survey name in the database using Survey Creator Conclusion In both cases, Survey Creator will show notifications. After getting a confirmation from the server, you can use the callback parameter and call it as callback(saveNo, true) in case of a success or callback(saveNo, false) in case server could not save the data for some reason. It means that if you saved the change #152 on the server, you can simply ignore changes #151 and below. Since web services are asynchronous by their nature, older changes may come after more recent changes. The callback has two parameters: a numeric saveNo and a callback function. If you enable it, the saveSurveyFunc callback is called on every change. Survey Creator has an isAutoSave property. Step 2: Save a survey JSON definition to the database. Since it is an asynchronous operation, we should use the Effect hook to prevent the component from re-rendering when the Survey Creator model changes. Step 1: Load a survey JSON definition from the database. ![]() All we need to do is call the getSurveyJSON and saveSurveyJSON functions from the WebDataService.js file. ![]() We pass survey ID into the Surve圜reatorWidget as props. Survey CRUD operations and routing Task 3: Load and save survey JSON definitions It will navigate to the following path for editing surveys: /editsurvey/:id. Create the SurveyListWidget component that will render the list of surveys, allow users to add a new survey and edit/delete existing surveys. Refer to the resulting Sandbox for a full code listing. In the code below, this file contains only function signatures for brevity. We will put all our data related functions into the WebDataService.js file. To simplify the code and let you modify data locally in your browser, we will use the browser’s local storage and emulate asynchronous calls using the setTimeout function. Step 1: Implement asynchronous functions that work with the database. If you are familiar with them, you can skip this section and go directly to Task 3. Unfortunately, in real-world apps, you have to repeat these steps for every application. We need to get the list of surveys from a database, allow users to create a new survey, and change the name and JSON definition of an existing survey. This task bears no relation to SurveyJS functionality. Task 2: Show a survey list that supports CRUD operations and set up React routing ![]()
