在剃刀中使用包含“@"的javascript正则表达式 [英] Using javascript regex containing '@' in razor

问题描述

我正在剃刀视图页面中使用 javascript 执行电子邮件地址验证.我要使用的正则表达式类似于 在 JavaScript 中验证电子邮件地址?

I am performing email address validation with javascript in a razor view page. The regex I am going to use is similar to the one proposed at Validate email address in JavaScript?

但是，由于正则表达式包含@"字符，因此在尝试运行 Web 应用程序时出现解析器错误.

However, because the regex contains an '@' character, I am getting parser error when try to run the web app.

我的正则表达式看起来像

my regex looks like

/^...otherpart @* ... other part$/

我试图添加一个 '@' 字符来使原始正则表达式中的 ...@@* ...，这消除了编译错误，但似乎使正则表达式停止工作.(我们在另一个不使用 razor 引擎的网络应用程序中使用了它，所以我知道它有效).

I tried to add an '@' character to make the in the origin regex ... @@* ..., this eliminated the compilation error but seems to make the regex stops working. (we have used it in another web app that does not use razor engine, so I know it works).

还有其他方法可以转义@"字符吗?

Is there any other way to escape the '@' character?

推荐答案

你可以在它前面再添加一个@来转义@@，尝试省略量词<代码>*.如果这似乎不起作用，则在函数周围添加 ，它会告诉 Razor 不要解析内容.或者，您可以将 Javascript 放在单独的文件中以满足您的需求.

You can add another @ in front of it to escape @@, try leaving out the quantifer *. If this doesn't seem to work then add <text></text> around the function, it tells Razor to not parse the contents. Alternatively you can put Javascript in a separate file to accomplish your needs.

如果由于某种原因您的字符串中有多个 @@，请将代码块放在 @:@@ 前

If for some reason you have multiple @@ in your string, place code blocks ahead @:@@
