            ...
        }
        
    }, this)

        async : true, 
        
        callback : function (success, text) {

                ...
            }
        }, 
        scope : this,
        
        headers : {
            'X-Custom-Header1' : 'Value',

        }
    })

DESCRIPTION

JooseX.SimpleRequest is a simple XHR request abstraction (yet it works reasonably well across all major browsers). It implements only 'GET' requests. If you need more features, you may want to look for another package.

METHODS

getText

void getText(String url, true, Function callback, [Object scope])

The signature above corresponds to asynchrnous usage. Method do not return the value and do not throws exception on error. Instead, the success/error flag and returned text will be passed to callback functions, which will be executed in optional scope

String getText(String url)

The signature above corresponds to synchronous usage. Method returns the fetched text and throws exception on error.

void|String getText(Object params)

The signature above combine both variants of usage. The parameters for the call are passed as object with the following keys:

• url - url to fetch text from

• async - true for asynchrnous mode, false for synchronous

• callback - the callback function. Will be called in asynchronous usage mode as callback(success, text)

• scope - optional scope for callback

• headers - object which key/value pairs will be used to initialize the headers of the request
