Jquery Validator Adding custom validation methods

Background detection method

  PublicJsonresult Testclientnameisrepeat (stringNameintClientId =0)        {            if(string.

Extensions: Error messages for custom methods, such as who added this record to a query, can refer to the following code

$.validator.addmethod (' Pd_password ',function(value, Element) {varLen =value.length; if(len<6) {$ (Element). Data (' error-msg ', ' length cannot be less than 6 bits '); return false; }    if(len>15) {$ (Element). Data (' error-msg ', ' length cannot be greater than 15 bits '); return false; }    return true;}, function(params, Element) {return$ (Element). Data (' error-msg ');});
