Looking for advice on how to design a custom JavaScript widget?

I am currently working on a web application and I am in the process of developing a feedback form widget that users can easily embed on their websites. The data submitted through this widget will be securely stored within my web application. One important feature I would like to incorporate is user authentication, where individuals need to login using either my application's credentials or through a social media account such as Facebook before submitting any information.

This is quite new territory for me as I've never implemented something similar before. I'm not very familiar with raw javascript and my concern with using jQuery is the potential conflict it may create with the client's existing page structure. Additionally, I am curious about how to handle cross domain requests in this scenario.

It's worth noting that the initial version of my widget should appear in a popup style interface.

Thank you in advance for your assistance with this matter.

Answer №1

Alternatively, if neither an iframe nor a popup window suits your needs, you can achieve the same result with AJAX. In this case, you will either need to utilize JSONP or configure the Access-Control-Allow-Origin header in all your responses.

Nevertheless, using an iframe is arguably the most reliable option. It allows for immediate deployment of bug fixes without relying on clients to update their software manually.

Answer №2

If you're facing this issue, my suggestion would be to utilize an <iframe>. This can help prevent any potential conflicts with JavaScript between your frame and the main website, plus it is widely supported across major web browsers.

After implementing the window.open method, you should be able to open a popup window. Keep in mind that using popup windows comes with its challenges, as there isn't a foolproof way to detect if a popup has been blocked by different browsers, which could lead to user confusion.

Answer №3

If you're dealing with a popup, one simple solution is to create a link that opens the feedback page on your web application.

<head>
    <script type="text/javascript">
         function mypopup(url) {
              mypopup = window.open(
                 url,  
                 "mypopup",
                 "width=600,height=400,status=yes,scrollbars=yes,resizable=yes"
              );
              mypopup.focus();
         }
    </script>
</head>
<body>
    <a href="#" onclick="mypopup('http://example.com/feedbackform');">
       Open Feedback Form
    </a>
</body>
