Deploying Mermaid 部署美人鱼

Mermaid API: Mermaid API：

To deploy mermaid without a bundler, one can insert a script tag with an absolute address and a mermaid.initialize call into the HTML like so:
要在不使用捆绑器的情况下部署mermaid，可以在HTML中插入一个带有绝对地址的script标记和mermaid.initialize调用，如下所示： script 要在没有捆绑器的情况下部署mermaid，可以在HTML中插入一个带有绝对地址的script标记和一个mermaid.initialize调用，如下所示： mermaid.initialize 要在没有捆绑器的情况下部署mermaid，可以在HTML中插入一个带有绝对地址的script标记和mermaid.initialize调用，如下所示：

Security and safe diagrams 安全图

For public sites, it can be precarious to retrieve text from users on the internet, storing that content for presentation in a browser at a later stage. The reason is that the user content can contain embedded malicious scripts that will run when the data is presented. For Mermaid this is a risk, specially as mermaid diagrams contain many characters that are used in html which makes the standard sanitation unusable as it also breaks the diagrams. We still make an effort to sanitize the incoming code and keep refining the process but it is hard to guarantee that there are no loop holes.
对于公共网站来说，从互联网上的用户那里检索文本，并将内容存储起来以便在稍后阶段在浏览器中显示，这可能是不稳定的。原因是用户内容可能包含嵌入式恶意脚本，这些脚本将在数据呈现时运行。对于美人鱼来说，这是一个风险，特别是因为美人鱼图表包含了许多html中使用的字符，这使得标准的卫生设施无法使用，因为它也打破了图表。我们仍然努力净化传入的代码，并不断改进过程，但很难保证没有漏洞。

As an extra level of security for sites with external users we are happy to introduce a new security level in which the diagram is rendered in a sandboxed iframe preventing JavaScript in the code from being executed. This is a great step forward for better security.
作为针对外部用户的站点的额外安全级别，我们很高兴引入一个新的安全级别，在该级别中，图表在沙箱iframe中呈现，以防止代码中的JavaScript被执行。这是在加强安全方面向前迈出的一大步。

Unfortunately you can not have a cake and eat it at the same time which in this case means that some of the interactive functionality gets blocked along with the possible malicious code.
不幸的是，你不能有一个蛋糕，吃它在同一时间，这在这种情况下意味着一些互动功能得到阻止沿着可能的恶意代码。
