Saving an Image to LocalStorage and Displaying It on a New Page

When working with web forms, it's often necessary to handle image uploads and store them for later display. This article provides a comprehensive solution for uploading an image, saving it to localStorage, and displaying it on the next page.

Uploading and Displaying the Image

To upload and display an image on the current page, use an HTML input field with the type attribute set to 'file' and the onchange event handler that calls the readURL function. The function should use the FileReader API to read the selected image file and display it on the page using the src attribute of an image element.

Saving the Image to LocalStorage

Once the user fills out the rest of the form and clicks the 'Save' button, save all form inputs, including the image, as localStorage strings. To save the image, use the getElementById function to get the image element on the page, convert it to a Base64 string using a function like the one provided in the response, and store the string as a localStorage value.

Displaying the Image on the New Page

On the next page, create an image with a blank src attribute. When the page loads, use the localStorage.getItem function to retrieve the Base64 string of the image from localStorage, and apply it to the image's src attribute using the data:image/png;base64, prefix to indicate the image data format.
