HTML5 pattern exclude words

问题:

I want to exclude some unwanted words in an input field of textarea using the pattern function in HTML5.

so I want exclude word inside a text like 'viagra' and 'cialis'

How can I code this?

回答1:

You can use this regex :

^((?!viagra)(?!cialis).)*$

As explained in the post : Regular expression to match a line that doesn't contain a word?

you can use it

<input type="text" pattern="[^(^viagra$|^cialis$)]">
