disabled和readonly的区别?_html/css_WEB-ITnose
在博客园中看到这样一篇文章,关于disabled和readonly的区别,以前还真的没有注意它们的区别,还是有必要知道它们的区别的,所以转载了。
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、
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。
