asp.net mvc - Use "@" in html5 input pattern attribute with MVC -


does know how can use "@" within pattern attribute on html5 email input having mvc page?

<input type="email" pattern="^[a-za-z0-9._+-]+@[a-za-z0-9.-]+\.[a-za-z]{2,4}$">

at runtime error:

"[" not valid @ start of code block. identifiers, keywords, comments, "(" , "{" valid.

when use "data-pattern" instead of "pattern" can escape "@@", "pattern" fails too.

thanks in advance :)

it can done 2 ways:

render "@" through razor:

<input type="email" pattern="^[a-za-z0-9._+-]+@("@")[a-za-z0-9.-]+\.[a-za-z]{2,4}$">

with html encode:

<input type="email" pattern="^[a-za-z0-9._+-]+&#64;[a-za-z0-9.-]+\.[a-za-z]{2,4}$">
