Manual Validation of jQuery Validation Plugin verification plug-in, jqueryvalidation

Jquery. validate is a verification framework of jquery. With the advantages of jquery, we can quickly verify some common input and expand our own verification methods, it also provides good support for internationalization.

The normal verification mode is as follows:

<Form id = "ff" action = "xxx">... <input type = "submit" value = "submit"> </form> [java] view plaincopy: view the CODE piece on the CODE to derive to my CODE piece $ ('# ff' ). validate ()

In this way, you only need to click the submit button and the plug-in will automatically perform verification.

However, sometimes we want to click another button to verify the form and then perform the rest based on the form verification result.

Check the source code and find a form () method. This method is used for verification, although the literal meaning of the method is not consistent.

Then we can perform the following operations:

Var validator; // declare a global variable $ (function () {validator = $ ('# ff '). validate (); // This statement returns an object}) function add () {var B = validator. form (); // return a Boolean value if (B) {// Verification Successful // do add ...}} <button onclick = "add ()"> Save </button>

If an error occurs during verification, the error message is displayed. To clear the error message, call validator. resetForm ();

With the validator. form () and validator. resetForm () methods, we can flexibly use the verification plug-in.
