encodeForHTMLAttribute 与 encodeForJavaScript
encodeForHTMLAttribute vs encodeForJavaScript
我正在尝试找出 encodeForHTMLAttribute 和 encodeForJavaScript 之间的区别。尽管如此，我还是找不到将不受信任的数据用作 javascript 数据值的场景，这在使用 encodeForHTMLAttribute 转义时破坏了代码，但在使用 encodeForJavaScript.[= 转义后安全地工作15=]
我知道对于所有 javascript，建议使用 encodeForJavaScript。但我喜欢看到不同。
你的问题的答案很无聊：事实是将 HTML 实体编码字符串传递给 JavaScript 主要是未指定的操作。* JavaScript 期望传递给它的数据为 JavaScript 进行转义，除了某些 API 方法外，它不知道您要发送什么。
HTML and JavaScript 是不同的语言。如果您会注意到，它们都有不同的保留字符——有些相同，这意味着它们每个都有构成语言的保留字符，在该语言中使用它们时必须特别对待。
确保 javascript 将 始终 将传入代码视为数据的正确方法是对 JavaScript 进行转义。向它传递一个 HTML 实体编码的字符串， 可能 有效，但我们不得不说 可能 因为该行为未指定。我在开头链接的问题部分回答了你的问题的一个原因是 JavaScript 框架对你的输入进行这种处理是很常见的......所以你最好确保如果发生这种情况，数据JavaScript 被适当转义。否则它将解包您的 HTML 实体编码、呈现和执行脚本代码。
我把该死的部分留到最后：You can write legal JavaScript with only six characters. And none of these characters are commonly escaped by HTML encoders. Here's an entire guide on using JavaScript escaping like this to evade XSS filters. And for proof that it works, look here.

但是，如果您对 Javascript 的 <script> 标记之间的内容进行转义...它将被纯粹视为数据，不会被执行。
