Are you looking for a way to download files from the server using JavaScript and AJAX? Well, you're in luck! In this tutorial, we'll go over how to use JavaScript and AJAX to download files from the server in a few simple steps.
Step 1: Set Up Your HTML
First, let's create a button in your HTML to trigger the file download. You can use a simple HTML button element and add an onclick event to trigger the download function.
Step 2: Write the JavaScript Function
Next, let's write the JavaScript function to handle the file download. We can use the fetch API to make a request to the server and download the file. Here's an example of how you can write the function:
```javascript
function downloadFile() {
fetch('http://example.com/file.pdf')
.then(response => response.blob())
.then(blob => {
let url = window.URL.createObjectURL(blob);
let a = document.createElement('a');
a.href = url;
a.download = 'file.pdf';
document.body.appendChild(a);
a.click();
window.URL.revokeObjectURL(url);
});
}
```
In this example, we're using the fetch API to make a request to the server to download the file. Once we have the file data, we create a URL for the file and create a new element with the download attribute set to the file name. We then append the element to the document, trigger a click event on the element, and finally revoke the URL to clean up after the download.
