Categorized request examples and articles tagged with [javascript-post] keyword How do I send a POST request using JavaScript?
To make an HTTP POST request from a web browser, JavaScript offers two primary methods: the promise-driven fetch() API and the callback-driven XMLHttpRequest object. To send POST requests from Node.js, you can use the native "http" module. To make a POST request with JavaScript Fetch API, you must indicate the HTTP POST method name with the "method" parameter and the POST payload in the "body" parameter. Extra HTTP request headers can be set with the "headers" parameter. In this JavaScript POST request example, we send a POST request to the ReqBin echo URL using the fetch() method. Below are additional examples of sending JavaScript POST requests with XMLHttpRequest object. Click "Execute" to make a JavaScript POST request online and see the result.
How to make requests using XMLHttpRequest in JavaScript?
To make a request using a JavaScript XMLHttpRequest object, you must first create an XMLHttpRequest object and then open the target URL by calling the xhr.open() method. POST data can be sent to the server by passing it to the xhr.send() method. Custom HTTP headers can be added to the request using the xhr.setRequestHeader(). The xhr.onload event will be fired after the XMLHttpRequest object has completed the asynchronous request. An xhr.status value of 200x indicates that the request was successful, 300x indicates a redirect, and 400x and 500x indicate an error. In this JavaScript XMLHttpRequest Request example, we make a request to the ReqBin echo URL. Click Execute to run JavaScript XMLHttpRequest example online and see the result.
