Add SurveyJS Dashboard to a Knockout or jQuery Application

This step-by-step tutorial will help you get started with SurveyJS Dashboard in a Knockout or jQuery application. To add SurveyJS Dashboard to your application, follow the steps below:

As a result, you will create the following dashboard:

See the Pen SurveyJS - Add SurveyJS Dashboard to a Knockout or jQuery Application by RomanTsukanov (@romantsukanov) on CodePen.

SurveyJS Dashboard is powered by Knockout and does not have an individual implementation for jQuery. However, you can integrate the version for Knockout into your jQuery application by following the same instructions.

Link Resources

SurveyJS Dashboard depends on other JavaScript libraries. Reference them on your page in the following order:

  1. Knockout

  2. Survey Core
    A platform-independent part of the SurveyJS Library that works with the survey model. SurveyJS Dashboard requires only this part, but if you also display the survey on the page, reference the rest of the SurveyJS Library resources as well.

  3. Plotly.js and Wordcloud
    Wordcloud (optional) is used to visualize the Text, Multiple Text, and Comment question types. Plotly.js (required) is used to visualize the rest of the question types.

  4. SurveyJS Dashboard
    A library that integrates Survey Core with Plotly.js and Wordcloud.

The following code shows how to reference these libraries:

<head>
    <!-- ... -->
    <script type="text/javascript" src="https://unpkg.com/knockout/build/output/knockout-latest.js"></script>

    <!-- SurveyJS Library resources -->
    <script type="text/javascript" src="https://unpkg.com/survey-core/survey.core.min.js"></script>
    <!-- Uncomment the following lines if you also display the survey on the page -->
    <!-- <link href="https://unpkg.com/survey-core/defaultV2.min.css" type="text/css" rel="stylesheet"> -->
    <!-- <script type="text/javascript" src="https://unpkg.com/survey-knockout-ui/survey-knockout-ui.min.js"></script> -->

    <!-- Third-party visualization libraries -->

    <!-- Uncomment the following line if you use the Text, Multiple Text, or Comment question types in your surveys -->
    <!-- <script src="https://unpkg.com/wordcloud/src/wordcloud2.js"></script> -->

    <!-- SurveyJS Dashboard resources-->
    <link href="https://unpkg.com/survey-analytics/survey.analytics.min.css" rel="stylesheet">
    <script src="https://unpkg.com/survey-analytics/survey.analytics.min.js"></script>
</head>

Load Survey Results

You can access survey results as a JSON object within the SurveyModel's onComplete event handler. Send the results to your server and store them with a specific survey ID. Refer to the Handle Survey Completion help topic for more information.

To load the survey results, send the survey ID to your server and return an array of JSON objects:

const SURVEY_ID = 1;

loadSurveyResults("https://your-web-service.com/" + SURVEY_ID)
    .then((surveyResults) => {
        // ...
        // Configure and render the Visualization Panel here
        // Refer to the help topics below
        // ...
    });

function loadSurveyResults (url) {
    return new Promise((resolve, reject) => {
        const request = new XMLHttpRequest();
        request.open('GET', url);
        request.setRequestHeader('Content-Type', 'application/x-www-form-urlencoded');
        request.onload = () => {
            const response = request.response ? JSON.parse(request.response) : [];
            resolve(response);
        }
        request.onerror = () => {
            reject(request.statusText);
        }
        request.send();
    });
}

For demonstration purposes, this tutorial uses predefined survey results. The following code shows a survey model and the structure of the survey results array:

const surveyJson = {
    elements: [{
        name: "satisfaction-score",
        title: "How would you describe your experience with our product?",
        type: "radiogroup",
        choices: [
            { value: 5, text: "Fully satisfying" },
            { value: 4, text: "Generally satisfying" },
            { value: 3, text: "Neutral" },
            { value: 2, text: "Rather unsatisfying" },
            { value: 1, text: "Not satisfying at all" }
        ],
        isRequired: true
    }, {
        name: "nps-score",
        title: "On a scale of zero to ten, how likely are you to recommend our product to a friend or colleague?",
        type: "rating",
        rateMin: 0,
        rateMax: 10,
    }],
    showQuestionNumbers: "off",
    completedHtml: "Thank you for your feedback!",
};

const surveyResults = [{
    "satisfaction-score": 5,
    "nps-score": 10
}, {
    "satisfaction-score": 5,
    "nps-score": 9
}, {
    "satisfaction-score": 3,
    "nps-score": 6
}, {
    "satisfaction-score": 3,
    "nps-score": 6
}, {
    "satisfaction-score": 2,
    "nps-score": 3
}];

Configure the Visualization Panel

Analytics charts are displayed in a Visualization Panel. Specify its properties in a configuration object. In this tutorial, the object enables the allowHideQuestions property:

const vizPanelOptions = {
    allowHideQuestions: false
}

Pass the configuration object, survey questions, and results to the VisualizationPanel constructor as shown in the code below to instantiate the Visualization Panel. Assign the produced instance to a constant that will be used later to render the component:

const surveyJson = { /* ... */ };
const surveyResults = [ /* ... */ ];
const vizPanelOptions = { /* ... */ };

const survey = new Survey.Model(surveyJson);

const vizPanel = new SurveyAnalytics.VisualizationPanel(
    survey.getAllQuestions(),
    surveyResults,
    vizPanelOptions
);

const vizPanelOptions = {
    allowHideQuestions: false
}

const vizPanel = new SurveyAnalytics.VisualizationPanel(
    survey.getAllQuestions(),
    surveyResults,
    vizPanelOptions
);

Render the Visualization Panel

Switch to the component template. Add a page element that will serve as the Visualization Panel container:

<body>
    <div id="surveyVizPanel"></div>
</body>

To render the Visualization Panel in the page element, call the render(containerId) method on the Visualization Panel instance you created in the previous step:

document.addEventListener("DOMContentLoaded", function() {
    vizPanel.render("surveyVizPanel");
});
