Here's how you can do it:

<input type="file" id="fileInput" style="display:none;">

<button onclick="document.getElementById('fileInput').click()">Select File</button>

In this example, we have created an input element with an ID of "fileInput" and set its display to "none" so that it is hidden on the page. We have also created a button element that, when clicked, triggers a click event on the input element using JavaScript.

When the button is clicked, the 'Select File' dialog box will open and allow the user to select a file. Once a file is selected, you can access it using JavaScript and perform any necessary actions.


By using a hidden input element and triggering a click event on it with JavaScript, you can easily open the 'Select File' dialog box programmatically. This is a simple solution that can be implemented quickly and easily in your JavaScript code.
