regex - Invalid regular expression HTML Pattern -

-

this regex:

pattern="[^\!\#\$\%\^\&\*\'\|\"]{8}" pattern="[^!#$%^&*'|"]{8}"

how invalid in html input tag? want symbols restricted in textbox

<input placeholder="something" type="text" required autofocus ng-model="somedata" pattern="[^\!\#\$\%\^\&\*\'\|\"]{8}">

i think should pattern=\"[^!#$%^&*'|"]{8}\"

you should escape literal double quote outside [] instead of inside.
