jquery validate plugin - How avoid from user insert white-spaces in input

Question

How avoid from user insert white-spaces in ? (I use jquery.validate.js plugin)

Example:

input not possible(because user not able insert white-spaces): John Pitt My

input possible:JohnPittMy

Edit:

use of regex in this case mistake - should be used only value.indexOf(' ')
please I asking how to that with only http://docs.jquery.com/Plugins/Validation

Thanks

with the indexof there is a problem that the keydown is called when the key is pressed so you cant check that the .value contains a bad char or not, and if you trying to check with the keyup event, you cant interrupt the key pressing. — Gergely Fehérvári

There's a JQuery plugin called AlphaNumeric...

Can i do the same with validate plugin?

You can actually do it with just JQuery. The unpacked version of the plugin is about 80 lines long with just 3 or 4 main functions... pretty simple if you'd like to look at the js and see how Paulo Marinas did it.

if(value.match(/^([^\s])*$/)) {return true;}

hope this good.not tested. mut mainly you should use regular expression.

preventing insert spaces:

$("#username").keypress(function(e) {
     if(e.which == 32) {
        e.preventDefault();
     }
})

does exist option to take every inserted char to input and check if he equal to ' '?

Gergely Fehérvári Over a year ago

you mean only space not whitespace?

Ben Over a year ago

in the input should prevent insert ' '

e.preventDefault() or return false, not both

I'll try to use a regular expression to validate the input.

A regular expression like: /([a-z]*[A-Z]+)+|([a-z]+[A-Z]*)+/ (only letters upper and lower case)

I don't know exactly how to express this regular expression.

But what you need it is any to test your input value that doesn't allow whitespaces.
