If you want to use Spanish chars in your 3 alphanumeric validation you can use this:
jQuery.validator.addMethod("alphanumeric", function(value, element) {
return this.optional(element) || /^[a-zA-Z0-9áéíóúÁÉÍÓÚÑñ ]+$/.test(value);
});
I 2 also added a blank space to let users add 1 words
You can use regexes in JavaScript:
if( yourstring.match(/^[a-zA-Z0-9]+/) ) {
return true
}
Note that 2 I used + instead of *. With * it would return 1 true if the string was empty
// use below ... It is better parvez abobjects.com
jQuery.validator.addMethod("postalcode", function(postalcode, element) {
if( this.optional(element) || /^[a-zA-Z\u00C0-\u00ff]+$/.test(postalcode)){
return false;
}else{
return this.optional(element) || /^[a-zA-Z0-9]+/.test(postalcode);
}
}, "<br>Invalid zip code");
rules:{
ccZip:{
postalcode : true
},
phone:{required: true},
This will validate zip code having no letters but alphanumeric
