Checking for a character

Copy linkTweet thisAlerts:
Aug 29.2006

Similar to checking for valid email addresses I need to check for just a slash in a form field. I know nothing about regular expressions so my attempts at hacking a email validation script have not paid off. I just need to make sure users do not enter a slash in a description field.

If someone could please point me to a sample script that would be great!!! I look at regular expressions and about loose my mind.

THANKS!!!!!!

@mishkinAug 29.2006 — ok, this is easy you'll be pleased to hear. I'll assume your field is a standard

<input type="text">. When you declare it give it a unique ID, for example:

<input type="text id="uniqueID">.

Next have your submit button call this function.

checkField()

{

fieldValue = document.getElementById("uniqueID")

if(fieldValue.value.indexOf("/"))

{

alert("sorry, '/' is an illegal character")

}

else

{

alert("There was no '/' found")

}

}

Or some variant of that should do the trick.
