The transfer of files over the internet is a common occurrence in today’s world. Files can range from small text documents to large media files, which can make the transfer process a little cumbersome. In some cases, the upload process can take several minutes or even hours, especially when using traditional transfer methods such as FTP or HTTP. However, thanks to Javascript libraries such as ajaxfileupload.js, the process can be much smoother and faster.

What is ajaxfileupload.js?

Ajaxfileupload.js is a light-weight Javascript library that makes it effortless to upload files to a server from a web page. It uses AJAX (Asynchronous Javascript and XML) technology, which enables the upload process to happen without having to refresh the entire web page. Therefore, it provides a fast and smooth file transfer experience for the user. It supports various file input types such as image, audio or video and can be used in various applications, making it a valuable tool for web developers.

How to use ajaxfileupload.js?

Using ajaxfileupload.js is easy and straightforward. First, you need to download the library and include it in your project. You can either download the source code or use a CDN (Content Delivery Network) to include it quickly in your project. Once you have included the library, you need to create a form to select a file for upload. The form should have an input tag that has the type attribute set to file.

```html

```

In the above HTML code, the form has an input tag with the id “file”, which defines the file input field. Next, add an event listener to the form’s submit button, which will handle the file upload.

```javascript

$("#upload").click(function() {

var file = $("#file")[0].files[0];

$.ajaxFileUpload({

url: 'upload.php',

secureuri: false,

fileElementId: 'file',

dataType: 'json',

data: {'file': file},

success: function (data, status) {

// handle success

},

error: function (data, status, e) {

// handle error

}

});

return false;

});

```

In the above code, the click event is triggered when the user clicks on the upload button. It retrieves the selected file using the file input field id, then initiates the file upload process using ajaxFileUpload call. The call passed several parameters to ajaxfileupload.js, including the file URL’s target location on the server, the file input field’s ID, the data type expected in the server’s response and if the upload should be secure or not. After the upload completes, the success event handles the response.
