Class Ext.data.Connection

- - - - - - -
Package:Ext.data
Defined In:Connection.js
Class:Connection
Subclasses:Ajax
Extends:Observable
-
- * -

The class encapsulates a connection to the page's originating domain, allowing requests to be made -either to a configured URL, or to a URL specified at request time.

-

Requests made by this class are asynchronous, and will return immediately. No data from -the server will be available to the statement immediately following the request call. -To process returned data, use a -success callback -in the request options object, -or an event listener.

-

File Uploads

File uploads are not performed using normal "Ajax" techniques, that -is they are not performed using XMLHttpRequests. Instead the form is submitted in the standard -manner with the DOM <form> element temporarily modified to have its -target set to refer -to a dynamically generated, hidden <iframe> which is inserted into the document -but removed after the return data has been gathered.

-

The server response is parsed by the browser to create the document for the IFRAME. If the -server is using JSON to send the return object, then the -Content-Type header -must be set to "text/html" in order to tell the browser to insert the text unchanged into the document body.

-

Characters which are significant to an HTML parser must be sent as HTML entities, so encode -"<" as "&lt;", "&" as "&amp;" etc.

-

The response text is retrieved from the document, and a fake XMLHttpRequest object -is created containing a responseText property in order to conform to the -requirements of event handlers and callbacks.

-

Be aware that file upload packets are sent with the content type multipart/form -and some server technologies (notably JEE) may require some custom processing in order to -retrieve parameter names and parameter values from the packet content.
