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 = $('<span>',{
className: 'tzCheckBox '+(this.checked?'checked':''),
html:'<span class="tzCBContent">'+labels[this.checked?0:1]+
'</span><span class="tzCBPart"></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);
