如果没有显示颜色选择器,我想添加一个
jquery颜色选择器回退.例如,chrome显示一个颜色选择器,但到目前为止,safari只显示一个文本框.有没有任何方式(没有用户代理)来检测颜色选择器是否可用？
编辑：Modernizr是不错的,因为它只会说safari也支持它. Safari支持输入类型颜色,因为它不允许在输入框中输入#hex颜色.但是没有颜色选择器.我需要知道是否有颜色选择器.
解决方法
干得好.

// These types can enable native datepickers,colorpickers,URL validation,and so on.
// If a browser doesn’t support a given type,it will be rendered as a text field. Modernizr
// cannot detect that date inputs create a datepicker,the color input create a colorpicker,// and so on—it will detect that the input values are sanitized based on the spec. In the
// case of WebKit,we have received confirmation that sanitization will not be added without
// the UI widgets being in place.
