What's New in SurveyJS v3.0

Survey logic can depend on data supplied by your application at runtime. For example, a support form might enable priority support only for premium customers. Survey Creator v3.1.1 introduces variable presets: named sets of sample values that let form authors test these conditions in the Preview tab.

To enable this functionality, use the variablePresets object. Its definition property describes the variables and how to edit them; its presets array supplies the values to test:

const creator = new SurveyCreator.SurveyCreator({
  variablePresets: {
    definition: {
      elements: [{
        type: "dropdown",
        name: "customerTier",
        title: "Customer plan",
        choices: ["basic", "premium"]
      }]
    },
    presets: [
      { name: "Basic member", variables: { customerTier: "basic" } },
      { name: "Premium member", variables: { customerTier: "premium" } }
    ]
  }
});

Use curly brackets to reference variables in survey expressions, just as you would reference question names. In this example, enableIf enables the priority support question when customerTier is "premium":

creator.JSON = {
  elements: [{
    type: "boolean",
    name: "prioritySupport",
    title: "Would you like priority support?",
    enableIf: "{customerTier} = 'premium'"
  }]
};
creator.activeTab = "preview";

Form authors can now switch between Basic member and Premium member at the bottom of the Preview tab to test the condition. To try other values, they can click Manage presets to edit or add presets. They can also use the variables in visual condition editors.

Preset edits stay in memory for the browser session. To save them for later use, handle the onVariablePresetsChanged event and pass the updated presets to your application's save function:

creator.onVariablePresetsChanged.add((_, options) => {
  if (options.reason === "edit") {
    // Replace with your application's save function.
    saveVariablePresets(options.variablePresets);
  }
});
