Twitter Bootstrap/jQuery - 如何暂时防止模式被关闭?

Thanks to @David and his suggestion at How to Extend Twitter Bootstrap Plugin I finally got it to work. It is a slightly modified version of his solution with modal "lock" added. I post it as a additional answer since I think it may could be a starting point for others that like me have struggled hard with this issue.

// save the original function object
var _superModal = $.fn.modal;

// add locked as a new option
$.extend( _superModal.defaults, {
    locked: false
});

// create a new constructor
var Modal = function(element, options) {
    _superModal.Constructor.apply( this, arguments )
}

// extend prototype and add a super function
Modal.prototype = $.extend({}, _superModal.Constructor.prototype, {
    constructor: Modal

    , _super: function() {
        var args = $.makeArray(arguments)
        // call bootstrap core
        _superModal.Constructor.prototype[args.shift()].apply(this, args)
    }

    , lock : function() {
        this.options.locked = true
    }

    , unlock : function() {
        this.options.locked = false
    }

    , hide: function() {
        if (this.options.locked) return
        this._super('hide')
    }
});

// override the old initialization with the new constructor
$.fn.modal = $.extend(function(option) {
    var args = $.makeArray(arguments),
    option = args.shift()

    // this is executed everytime element.modal() is called
    return this.each(function() {
        var $this = $(this)
        var data = $this.data('modal'),
            options = $.extend({}, _superModal.defaults, $this.data(), typeof option == 'object' && option)

        if (!data) {
            $this.data('modal', (data = new Modal(this, options)))
        }
        if (typeof option == 'string') {
            data[option].apply( data, args )
        }
    });
}, $.fn.modal);

使用这种技术，无需更改 bootstrap.js，并且可以更轻松地在 bootstrap 项目之间共享相同的功能.此方法应适用于所有其他引导插件.到目前为止只尝试过按钮，但我不知道为什么不应该这样做.
