How to add code from html file to textarea using JavaScript(jQuery) or Node.js?

Question

JavaScript

Hello!
How can I insert code from html file into textarea using JS? Or open this file, copy the code from there and also paste it with Node(fs)?

Answer 1

With jQuery:

$( "#textarea" ).load( "url-of-file-to-load", function( response, status, xhr ) {
  if ( status == "error" ) alert( "Sorry but there was an error: " + xhr.status + " " + xhr.statusText );
  else $( this ).val(response);
});

As tef said , you can use the default fs for the node, everything is pretty simple there, no problems should arise.

Answer 2

If you need to do it in a browser, google fileAPI. If node.js, then this is the fs module, which, if necessary, can be googled.
