how write validations (vtypes) in separate js file

vtypes phone nos ,datefields , emails

thanq 2 have write separate file common validation

regards

custom vtypes can done few simple steps:

• apply custom object ext.form.vtypes
• include file above in page
• use vtype other field

more specifically:

//seperate file, validation.js ext.apply(ext.form.vtypes, {     your_v_type_nametext: "invalid!", //optional, message show when field invalid     your_v_typemask: /.*/ //optional, regular expression characters cannot included     your_v_type: function(value) {         return false; //some expression evaluates true or false validate field     } });   //your main file, main.html //other javasript <script type="text/javascript" src="validation.js"></script> 

all need replace your_v_type actual name of vtype, , when create field, set vtype property vtype.

several validation types natively supported, if want create 1 phone numbers or email addresses, suggest using regular expression. there large library of these available regular expression library
