Download Pdf File Using Jquery Ajax

Downloading PDF files using jQuery AJAX is a handy technique that brings together the power of JavaScript and server-side interactions to make your web experience smoother. In this article, we will guide you through the process step-by-step. So, let's dive in and learn how to accomplish this task effortlessly.

First and foremost, make sure you have included the jQuery library in your project. This will provide you with the tools needed to perform AJAX requests seamlessly. You can either download the library and include it locally in your project or use a CDN link to access it directly.

Next, you will need to create a button or any element on your web page that will trigger the download process. Assign it an ID or a class for easy reference in your jQuery code.

Now, let's write the jQuery AJAX code to efficiently download the PDF file. You can use the following snippet as a starting point:

$('#downloadButton').on('click', function() {
    $.ajax({
        url: 'path/to/your/pdf-file.pdf',
        method: 'GET',
        xhrFields: {
            responseType: 'blob'
        },
        success: function(data) {
            var a = document.createElement('a');
            var url = window.URL.createObjectURL(data);
            a.href = url;
            a.download = 'your-pdf-file.pdf';
            document.body.appendChild(a);
            a.click();
            window.URL.revokeObjectURL(url);
        }
    });
});

In this code snippet, we utilize a jQuery AJAX request to fetch the PDF file from the specified URL. By setting the `responseType` to `'blob'`, we ensure that the response is treated as a binary object.

Once the PDF file is successfully retrieved, we create a hidden anchor element (``) and set its `href` attribute to the URL of the PDF file. We also specify the `download` attribute with the desired filename for the downloaded file.
