Title
Body
I have a simple html text box. When I "submit" the form that the text box is in, I would like to get a variable with the number of words inside using Jquery. I would also like to check if the inputted text is only letters, numbers and hyphens (also in jquery). I do not need to count the words as the user types, just when the form is submitted. The form won't submit if jquery is turned off so I guess there are no security risks by not using php. Is this true? HTML: <input type='text' name='name' id='name' /> <input type='button' value='Sign Up' id='signUp'> JQUERY (attempt): var wordcount = $('#name').val() // i don't know how to count the words
