具体代码如下：
(function($){ $.fn.tzCheckbox = function(options){ // Default On / Off labels: options = $.extend({ labels : ['ON','OFF'] },options); return this.each(function(){ var originalCheckBox = $(this), labels = []; // Checking for the data-on / data-off HTML5 data attributes: if(originalCheckBox.data('on')){ labels[0] = originalCheckBox.data('on'); labels[1] = originalCheckBox.data('off'); } else labels = options.labels; // Creating the new checkbox markup: var checkBox = $('<span>',{ className: 'tzCheckBox '+(this.checked?'checked':''), html:'<span>'+labels[this.checked?0:1]+ '</span><span></span>' }); // Inserting the new checkbox, and hiding the original: checkBox.insertAfter(originalCheckBox.hide()); checkBox.click(function(){ checkBox.toggleClass('checked'); var isChecked = checkBox.hasClass('checked'); // Synchronizing the original checkbox: originalCheckBox.attr('checked',isChecked); checkBox.find('.tzCBContent').html(labels[isChecked?0:1]); }); // Listening for changes on the original and affecting the new one: originalCheckBox.bind('change',function(){ checkBox.click(); }); }); }; })(jQuery);
