Javascript - Load page on selection from dropdown form

To load a page when a selection is made from a dropdown form (select element) in JavaScript, you can use the onchange event handler. Here's a basic example of how you can achieve this:

HTML:

<select id="dropdown">
    <option value="">Select an option</option>
    <option value="page1.html">Page 1</option>
    <option value="page2.html">Page 2</option>
    <option value="page3.html">Page 3</option>
</select>

JavaScript:

document.getElementById('dropdown').onchange = function() {
    var selectedValue = this.value;
    if (selectedValue) {
        // Redirect to the selected page
        window.location.href = selectedValue;
    }
};

In this example:

  • We have a dropdown select element (<select>) with several options, each containing a value corresponding to a page URL.
  • We attach an onchange event handler to the select element.
  • When a user selects an option, the onchange event is triggered.
  • In the event handler function, we retrieve the selected value using this.value.
  • If a valid option (other than the default empty option) is selected (selectedValue is not an empty string), we redirect the user to the corresponding page using window.location.href.

Make sure to replace the placeholder page URLs with the actual URLs of the pages you want to navigate to. Additionally, consider enhancing this basic example with error handling and other features as needed for your application.
