Using javascript regex containing '@' in razor

Question

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 JavaS

Answer 1

Simply just use double @@.
It works for me and I think that is the only way.

Answer 2

Put the following inside the regEx instead of @:

@('@')

The above will be rendered to a single @.

Your example will become:

/^...otherpart @('@')* ... other part$/

Answer 3

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.

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

Answer 4

It's better to use @('@') instead of @@ (not working for me). Example

<input class="form-control" pattern="^[a-zA-Z@('@')]{5,20}$"/>
