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
You would split the string and then count the length of the resulting array.
$('input[type="submit"]').click( function() {
var words = $('#name').val().split(' ');
alert(words.length);
});
