Making Cross-Domain JSONP Requests in JavaScript Without External Libraries
JSONP (JSON with Padding) is a technique that allows cross-domain requests by appending a callback function to the request URL. The callback function is defined by the client and is executed by the server upon successful reception of the request.
How to Make a JSONP Request Without jQuery
To make a JSONP request without jQuery, you can follow these steps:
<code class="javascript">function foo(data) { // Process the JSON data }</code>
<code class="javascript">const url = '//example.com/path/to/jsonp?callback=foo';</code>
<code class="javascript">const script = document.createElement('script'); script.src = url;</code>
<code class="javascript">document.head.appendChild(script); // or document.getElementsByTagName('head')[0].appendChild(script) in older browsers</code>
Once the server responds with the JSON data, the callback function will be executed and you can use the provided data to populate your application.
