Loading a javascript file in an asynchronous manner

Attempting to perform an asynchronous call to a server using the following method:

$(document).ready(function(){
    $.ajax({
    cache: true,
        async: true,
        dataType: "script",
        url:"www.xyz.com/yyy?host_name=abc.com&size=S&use_flash=YES&use_transparent=YES&lang=en",
       success: function(data) { 
            $("#verified").append(data);
                console.log("data is "+data);
                loading = false; 
            } 
       });
});

Despite this, the script does not load asynchronously. What am I overlooking? Any assistance would be greatly appreciated!

Answer №2

Utilize the code snippet below to load JavaScript asynchronously

 function loadScript(url) {
        var scriptElement = document.createElement('script');
        scriptElement.type = 'text/javascript';
        scriptElement.async = true;
        scriptElement.src = url;
        document.getElementsByTagName('head')[0].appendChild(scriptElement);            
    }

Answer №3

By default, the "cache" and "async" properties for ajax calls are set to "true," so there's no need to specify them again.

If you're experiencing slow loading times for your file, it could be due to its large size - typically over 50 or 100 kb. To speed up the loading process, consider minifying your JS file to reduce its size and improve loading speed during ajax calls.

is a great online tool for minifying your scripts.

Another option is to utilize the requirejs library, which is popular for asynchronously loading script files. You can download the requirejs library from this link: http://requirejs.org/docs/download.html
