javascript - How to validate email with jQuery Validate plugin -


In some cases, jQuery is not perfect for email verification. "Abc@test.c" (single letter suffix) and "중국어 @ test.com" (non alpha-numerical) are passed as valid email addresses.

How can I use these two invalid email addresses in the jQuery validated plugin?

, you will need to create your own custom method.

Add a custom verification method. It should have a name (must be a valid JavaScript identifier), a JavaScript-based function and a default string message.

Argument:

Names; String method is used to name, identify and reference, should be a valid JavaScript identifier

method; Callback actual method implementation, if any element is valid then true. First argument: current value second argument: valid element third argument: parameter

Message (optional); The default message for displaying the string, the function for this method There may be a function created by JQuery.validator.format (value). When the undefined, pre-existing message is used (easy to localize), otherwise the field-specific message must be defined.

The following is a custom method which I have named newemail . Right now, it is just using the default function for "email" verification just edit the regex in this function corresponding to your particular requirements. 

  jQuery.validator.addMethod ("newmail", function (value, element) {// contributed by Scott Gonzalez: http: // Projects.scottsplayground.com/email_address_validation/ this return.optional (element) || / ^ ((([az] | \ d | [! # \ $% & Amp; * \ + \ - \ / = \ \ ^ _ `?.. {\ |} ~] | [\ U00A0- \ uD7FF \ uF900- \ uFDCF \ uFDF0- \ uFFEF]) + (\ [[az] | \ d | [# \ $% &?!? \ * \ + \ - \ / = \ \ ^ _ `{\ |} |] | [\ u00A0- \ uD7FF \ uF900- \ uFDCF \ uFDF0- \ uFFEF]) +) *) | ((\ X22) ( (((\ X20 | x09) * (\ x0d \ x0a)) (\ x20 |? \ X09) +)?

[\ U00A0- \ uD7FF \ UF900- \ uFDCF \ uFDF0- \ uFFEF]) | (([az] | [\ u00A0- \ uD7FF \ uF900- \ uFDCF \ uFDF0- \ uFFEF]) ([az] | \ d | - |. \ | _ | ~ | [\ U00A0- \ Ud7FF \ Ufar900- \ Ufdsf \ Ufdf0- \ Ufarfafa]) * ([today] | [\ U00A0- \ Ud7FF \ Ufar900- \ Ufdsf \ Ufdf0- \ Ufarfafa]))) $ / e .test (value); }, "Please enter a valid e-mail address");

Use the inside then it .validate () as you would use any other rule. 

  Rules: {InputName: {required: true, Nyamel: true}}

mongodb - CakePHP paginator ignoring order, but only for certain values -

While pagging my user model in kppp, I can sort with some values, but not others. For example, I can order results from created or email , for example, but username or reputation seems to come back order by arbitrary command for example with a list of users: $ this-> paginate = array ('condition' => array ( 'User.is_active' = & gt; true), 'border' => 24, 'order' => array ('User.created' => DESC)); Works as expected, but $ this - & gt; Paged = array ('conditions' = & gt; array (' user.isIactive '= & gt; true),' border '= & gt; 24,' command '= & gt; array (' user repeats' = ' & Gt; DESC ')); No, no. I first thought that this could be a database issue, but when I search the database directly, sorted as expected. Note: I am using Mangodebi with the Mongo DB plugin of Ichikawa for the KPPHP; Pagnetizing users are used to work properl...
