requiredfeatures
该属性采用特征字符串列表,各个字符串之间用空格分隔。它决定了浏览器是否支持所有命名功能。如果所有这些都受支持,则该属性评估为true结束呈现的元素;否则,该属性的计算结果为false,并且当前元素及其子元素被跳过,因此不会被渲染。这提供了一种设计SVG的方法,当功能不可用时,SVG会优雅地退后。
如果该属性不存在,则其隐式评估值为true。如果给属性赋予一个空字符串或空字符串值requiredFeatures,则该属性评估为false。
requiredFeatures通常与<switch>元素一起使用。如果requiredFeatures在其他情况下使用,则表示在给定元素上是否显示元素的简单开关。
如果您需要通过脚本检测SVG功能的可用性,则可以使用该DOMImplementation.hasFeature()方法。

<list-of-feature>这是使用空格分隔的特征字符串列表。确定浏览器是否支持所有命名功能。请参阅下面的特征字符串以获取允许的值列表。
特征字符串
以下是requiredFeatures属性的特征字符串。这些相同的特征字符串适用于hasFeature方法调用,它是SVG DOM对DOMImplementation接口的支持的一部分。在某些情况下,特征字符串直接映射到一组属性,属性或元素,而在其他情况下,它们代表浏览器的某些功能。请注意,功能字符串的格式和命名已从SVG 1.0更改为SVG 1.1。这里没有列出SVG 1.0特征字符串,但可以在SVG规范中找到。出于兼容性原因,某些浏览器支持SVG 1.0功能字符串。但是,SVG 1.0功能字符串已被视为弃用。
