xmlhttprequest send post data

 

 

 

 

Although XMLHttpRequest is most commonly used to send and receive textual data, it can be used to send and receive binary content. There are several well tested methods for coercing the response of an XMLHttpRequest into sending binary data. Instead, lets leverage XMLHttpRequests new responseType and response properties to inform the browser what format we want the data returned as.Sending string data: xhr.send(DOMString). function sendText(txt) var xhr new XMLHttpRequest() xhr.open(POST, /server, true) I am sending post data via XMLHttpRequest: var xmlHttpnew XMLHttpRequest() xmlHttp.open(POST, domain, true) xmlHttp .setRequestHeader(Content-type,multipart/form-data) var formData new Form. Is there a documented max to the length of the string data you can use in the send method of an XMLHttpRequest for the major browser implementations?

Initiates the request.

To send a request to a server, we use the open() and send() methods of the XMLHttpRequestSending a large amount of data to the server (POST has no size limitations).Sending user input (which can contain unknown characters), POST is more robust and secure than Id like to send some data using an XMLHttpRequest in JavaScript.
