Access Query Parameters in a Page

This section details how to access and utilize query parameters within Twidget pages, enabling dynamic content and functionality based on user-supplied parameters.

-

Key Concepts

  • Query Parameters: A method to pass data to web pages through the URL, enabling dynamic content updates based on user interaction or external inputs.

  • Dynamic Content: The capability of a page to change its displayed information based on the values of query parameters.

Main Components and Workflow

  1. Text Elements: Text fields can be dynamically updated with content derived from query parameters by embedding special syntax, which includes a dollar sign and double curly braces (e.g., {{$query.name}}). This syntax allows real-time data binding to URL parameters.

  2. Page Publishing: Once changes are made and content is set using query parameters, publishing the page enables public access, demonstrating the dynamic text updates with actual query values in the URL (e.g., ?name=twidget).

  3. Visibility and Other Settings: Query parameters can also be utilized in various element configurations, such as visibility settings, where they help tailor the user interface based on incoming data. These parameters appear in the variable dropdown during configuration, making them easily accessible.

  4. Functions: In addition to visual elements, query parameters can be accessed within page functions. Functions can be created to execute specific logic using query parameter values. For instance, a logging function can be implemented to track the values of the query parameters by referencing the query object (e.g., $query.name).

Overall, Twidget empowers users to create dynamic and responsive web pages that adapt based on the query parameters within the URL, greatly enhancing the interactive capabilities of web applications.
