Looking to identify the presence of < or > in user input using JavaScript. Anyone have a suggestion for the regular expression to use? The current regex is not functioning as expected.
var spclChar=/^[<>]$/;
if(searchCriteria.firstName.match(spclChar)){
return true;
}else {
return false;
}
If you're looking to match specific characters, consider using a character class like the examples below:
[<>]
or
[><]
Check out this demo for more details.
Also, there are some helpful comments provided by users in your question, such as insights from Sam:
/[<>]/
and feedback from Marc B:
Your regex may need adjustments based on Marc B's suggestions. - Marc B
