为MooTools 1.2创建一个自定义的伪选择器

Posted 2021-02-26

How to create a custom “:checked” pseudo selector for use in MooTools. It is just a small snippet but I’ve found it incredibly useful.

Selectors.Pseudo.checked = function(){  
	return (this.get('tag') == 'input' && (this.get('type').toLowerCase() == 'radio' || this.get('type').toLowerCase() == 'checkbox') && this.checked);  
};
