JavaScript 组织 |带模块的模块模式

Question

我将我的代码组织成 20-60 行模块，通常采用模块模式。我想要一个结构良好的面向对象的 JavaScript 库。

这是最好的方法吗？代码已经过测试并且有效。

我喜欢它，因为程序员可以从库中提取模块并根据需要使用它们，它们是自包含的。

这里是工具、消息、效果和文本，都包含在 NS 中。

问题？

这是组织我的图书馆的好方法(最佳实践)吗？

注意

到目前为止，评论和答案中的共识为 0...非常令人沮丧。

外部模块模式

var NS = ( function ( window, undefined ) 
{ 
/* All Modules below here */ 
} )( window );

工具

/**
 *Tools
 *    getTimeLapse - benchmark for adding
 */

var Tool = ( function () 
{
    var Tool = function ( ) 
    {
    };
    Tool.prototype.getTimeLapse = function( numberOfAdds ) 
    {
        var end_time;
        var start_time = new Date().getTime();
        var index = 0;           
        while ( index <= numberOfAdds )
        {
            index++;
        }
        end_time = new Date().getTime();
        return ( end_time - start_time );
    };
    return Tool;
} () );

/**
 *Message
 *    element - holds the element to send the message to via .innerHTML
 *    type - determines the message to send
 */

var Message = ( function () 
{
    var messages = 
    {
        name:         'Please enter a valid name',
        email:        'Please enter a valid email',
        email_s:      'Please enter a valid email.',
        pass:         'Please enter passoword, 6-40 characters',
        url:          'Please enter a valid url',
        title:        'Please enter a valid title',
        tweet:        'Please enter a valid tweet',
        empty:        'Please complete all fields',
        same:         'Please make emails equal',
        taken:        'Sorry, that email is taken',
        validate:     'Please contact <a class="d" href="mailto:foo@foo.com">support</a> to reset your password',

    Message.prototype.display = function( type )

        this.element.innerHTML = messages[ type ];
    };

效果

/**
 *Effects
 *    element - holds the element to fade
 *    direction - determines which way to fade the element
 *    max_time - length of the fade
 */

var Effects = ( function () 
{
    var Effects = function ( element )
    {
        this.element = element;
    };
    Effects.prototype.fade = function( direction, max_time ) 
    {
        var element = this.element;
        element.elapsed = 0;
        clearTimeout( element.timeout_id );
        function next()
        {
            element.elapsed += 10;
            if ( direction === 'up' )
            {
                element.style.opacity = element.elapsed / max_time;
            }
            else if ( direction === 'down' )
            {
                element.style.opacity = ( max_time - element.elapsed ) / max_time;
            }
            if ( element.elapsed <= max_time ) 
            {
                element.timeout_id = setTimeout( next, 10 );
            }
        }
        next();
    };
    return Effects;
} () );

文本

/**
 *Text
 *    form_elment - holds text to check
 */

var Text = ( function () 
{
    var Text = function ( form_element )
    {
        this.text_array = form_element.elements;
    };
    Text.prototype.patterns = 
    {
        prefix_url:     /^(http:)|(https:)\/\//,
        aml:            /<(.+)_([a-z]){1}>$/,

        pass:           /^.{6,20}$/
    };
    Text.prototype.checkPattern = function( type ) 
    {
        return this.patterns[ type ].exec( this.text_array[type].value );

    Text.prototype.checkUrl = function( type ) 
    {
        return this.patterns[ type ].exec( this.text_array.url.value );

    Text.prototype.checkEmpty = function()

为了使您的代码更简洁并减少其占用空间，我建议更改的一件事是立即设置原型(prototype)属性，这样就不用做

Object.prototype.method1 = function(){};
Object.prototype.method2 = function(){};

你会

Object.prototype = {
    method1: function(){},
    method2: function(){}
};

如果您需要保留构造函数引用，这是推荐的，您应该在之后重新分配构造函数。 See this answer for more details .
