<pre><code>function Ajax(){
    this.url = null;
    this.data = null;
    this.success = null;

    this.global = true;
    this.timeout = JSON_TIMEOUT;
    this.cache = false;
    this.dataType = 'json';
    this.type = 'post';

    var _this = this;

    this.send = function(){
        var jqxhr = $.ajax({
                url : this.url,
                data : this.data,
                timeout : this.timeout,
                cache : this.cache,
                dataType : this.dataType,
                type : this.type,
                global : this.global
                }
            )
            .success(this.success)
            .error(function(){
                Dialog.set_error({
                    headline : Lang.get('HDL_ERROR'),
                    body : Lang.get('ERR_TIMEOUT'),
                    btns : [
                        {
                            value : Lang.get('BTN_OK'),
                            script : function(){},
                            focus : true
                            }
                        ]
                    })
                })
            .complete(function(){
                    delete _this;
                });
    };
}
