Javascript错误 - 对象没有方法

Question

我缩短了以下脚本:

var HTH = HTH || {};

(function() {
    var assetGrouping = function() {
        var self = this;

        this.options = {
            _tmpElement:        '',
            QuantityAssigned:   0,
            qtyInputField:      ''
        };

        this.init = function(options){
            // ...
            this.options.QuantityAssigned = 0;
            jQuery(this.options.qtyInputField).bind('keyup', function(){
                self._tmpElement = jQuery(this);
                self.CalculateQuantityAssigned();
            });

            // ...
        }

        CalculateQuantityAssigned = function(){
            // ...
        }
    }

    HTH.assetGrouping = new assetGrouping();
})();

$(document).ready(function(){
    HTH.assetGrouping.init({
        qtyInputField: 'input[name^="at700_group_qty"]'
    });
});

错误发生在以下行:self.CalculateQuantityAssigned();错误是Uncaught TypeError: Object [object Object] has no method 'CalculateQuantityAssigned'.

我不明白.this当然,使用将失败并且self在我想要访问时工作self.options但不是self.CalculateQuantityAssigned().

谢谢.

更改:

CalculateQuantityAssigned = function(){
            // ...
}

至

this.CalculateQuantityAssigned = function(){
            // ...
}
