XMLHttpRequest send file and data


This code works in Chrome 12, Safari 5 and Firefox 4 and sends the raw contents of the file in the body of the HTTP request. However, if the file is big enough the request is never sent. Instead, the XMLHttpRequest object fires and error event (without any useful message). This limit is 86Mb in my environment, but it varies from machine to machine To send post data in JavaScript with XMLHTTPRequest, first, we have to create an XMLHTTPRequest object: var http = new XMLHttpRequest (); After that initialize it with the open () method with the request URL. We also pass the method post and set the asynchronous to true The send method of the XMLHttpRequest has been extended to enable easy transmission of binary data by accepting an ArrayBuffer, Blob, or File object. The following example creates a text file on-the-fly and uses the POST method to send the file to the server. This example uses plain text, but you can imagine the data being a binary file instead Finally, use the built-in XHR object to POST the data to the URL we defined above, and print the response on the console: const xhr = new XMLHttpRequest(); xhr. responseType = 'json'; xhr.onload = () => { console.log( xhr. response); }; xhr.open('POST', url); xhr.send( formData); Here is the complete upload.js file

The XMLHttpRequest object is a developers dream, because you can: Update a web page without reloading the page; Request data from a server - after the page has loaded ; Receive data from a server - after the page has loaded; Send data to a server - in the backgroun Being able to download data in different formats is great, but it doesn't get us anywhere if we can't send these rich formats back to home base (the server). XMLHttpRequest has limited us to sending DOMString or Document (XML) data for some time XMLHttpRequest is a built-in browser object in all modern browsers that can be used to make HTTP requests in JavaScript to exchange data between the web browser and the server. Despite the word XML in its name, XMLHttpRequest can be used to retrieve any kind of data and not just XML What has changed is what the XMLHttpRequest.send () call receives. Last year, we fed it an instance of the File interface. This time instead, we will give it an instance of FormData. FormData gives us two ways to interface with it

When the XMLHttpRequest (jQuery.ajax ()) method is sent, it cannot correctly send a FormData object that contains an empty file element in Microsoft Edge for Windows 10, version 1809. For example, you set a file that contains one file element only and all the other file elements blank as in the following code example XMLHttpRequest (XHR) is a built-in browser object that can be used to make HTTP requests in JavaScript to exchange data between the client and server.
