2.spellcheck="true"、'false'、""，值为true和""时，代表检查。。
【空字符串为什么检查：就跟input其他属性一样，你设置个readonly就是只读( readonly="")，再加个值描述的更准确。】
3.使用场合：
1.类型为text型的input元素，但input类型为text型的input元素，但input="password"不行(原因：你是密码哎，都是星号还检查个啥玩意,密码本身就是不同字母组合而出的)。
2.textarea元素
3.spellcheck属性，html5中的所有元素都可以指定，对于不是输入栏的元素，须指定contenteditable="true" 编辑属性，才能使用。(如div什么的。)
4.现代浏览器都支持以及IE10
