jquery实现的代替传统checkbox样式插件

(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 = $('',{
        className: 'tzCheckBox '+(this.checked&＃63;'checked':''),
        html:''+labels[this.checked&＃63;0:1]+
            ''
      });
      // 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&＃63;0:1]);
      });
      // Listening for changes on the original and affecting the new one:
      originalCheckBox.bind('change',function(){
        checkBox.click();
      });
    });
  };
})(jQuery);
