So this section will introduce to you in detail the specific method of jQuery to implement form verification submission.

In the above code, we simply wrote a form and submitted the front-end data to check1.php. Submit The method is post, and a click event is given to the form.

When we click submit, a series of information judgments will be made. And when we do not click to register, that is, the click event is not triggered, there will also be a judgment.

Such as the __changeUserName method in the code. In this method, we first use regular expressions to determine whether the email format is correct and whether the mobile phone number is correct. And in the checkPwd1 and checkPwd2 methods, determine whether the password meets the requirements and is the same as the first password. These methods are all verifications that occur when the registration button is not clicked.

Of course, these judgments are not enough, so we need to write a verification that will occur when clicking to register, such as the check method in the above code, in which we judge each field (required in the background) fields need to be verified).

In addition to the above verification method of click registration, we can also bind an event to the click registration button to determine verification. I won’t go into details here.
