disabled和readonly的区别是什么:
这两个属性有类似之处，但是区别也是巨大的，之所以说类似，是因为这两个属性好像都貌似能够将指定的元素设置为"不可用"状态，下面就简单介绍一下它们两个的区别,希望能够给大家带来一定的帮助。
一.作用范围不同:
disabled属性可以用语所有的表单元素。
readonly属性只对、和<input type="password">有效。 二.对元素的影响程度不同: disabled属性阻止对元素的一切操作，例如获取焦点，点击事件等等。 readonly属性只是将元素设置为只读，其他操作正常。 三.表达提交: disabled属性可以让表单元素的值无法被提交。 readonly属性则不影响提交问题。
