jQuery validate plugin : accept letters only?
I'm using the validate plugin from http://bassistance.de/jquery-plugins/jquery-plugin-validation/
What i'm trying to find is a way to make some of my form fields accept letters only, no numbers, special chars etc...
Any idea people ? Thanks a lot.
Simply add a custom validator, and use it like this:
jQuery.validator.addMethod("accept", function(value, element, param) {
return value.match(new RegExp("." + param + "$"));
});
Only numbers:
rules: {
field: { accept: "[0-9]+" }
}
Only letters
rules: {
field: { accept: "[a-zA-Z]+" }
}
A small change.
jQuery.validator.addMethod("accept", function(value, element, param) {
return value.match(new RegExp("^" + param + "$"));
});
Because that way it was accepting expressions like "#abc".
