Validating checkbox in javascript Teens sex chat free roms

I need the JS to require a user to select at least 1 checkbox, but the user can also select multiple checkboxes. When the user clicks submit, if they haven't selected one of the check boxes then a message should appear and not let the user submit the email.

Since the left hand side is now numeric, type coercion is again used.Adding HTML5 validation to the checkbox is actually very simple.All you need to do is include a This tells the browser that the form should not be allowed to submit without the checkbox checked.The check on the length is for a special case involving empty strings.Also note that it falls down on your 0x89f test, but that's because in many environments that's an okay way to define a number literal.If you want to catch that specific scenario you could add an additional check. Simply trimming the string before the length check will handle this case. Now you can ask questions directly to me on my new site ASPForums. It's so easy to make subtle, impossible to spot mistakes with your regular expression.If you can't use expression forces Java Script to do type coercion on your input value; it must first be interpreted as a number for the subtraction operation.This entry was posted on January 22, 2010, pm and is filed under Javascript.You can follow any responses to this entry through RSS 2.0.
