written into the JS codeFive, common methods and attention problems1. Replace the default submit in other ways$ (function () { $ ("#signupForm"). Validate ({ submithandler:function (form) { alert ("submit!"); Form.submit ();}); You can set the default value for validate, as follows:$.validator.setdefaults ({Submithandler:function (form) {alert ("submit!"); Form.submit ();}});If you want to submit a form, you need to use Form.submit () instead of $ (form)

The recent project uses the form verification, chooses the validform_v5.3.2.
Let's take a look at some basic parameters:
Common form authentication methods:
Demo:
$ (". Demoform"). ValidForm ({//$ (". Demoform") indicates which form needs to be validated, and the name should be added to the form form; Btnsubmit: "#btn_sub",//#btn_sub是该表单下要绑定点击提交表单事件的按钮;
If the form contains a submit button, the parameter can be omitted;
Btnreset: ". Btn_reset"
triggering when submitting
$ (". Selector"). Validate ({
invalidhandler:function (event, validator) {
//event: Custom Event Object
//validator : The currently validated instance
}
});
Ignore-Some elements are not validated
$ ("#myform"). Validate ({
ignore: ". Ignore")

Two local yum source configuration methods: Oracle database software depends on many software packages. If you use rpm commands to add one by one, it is very troublesome and the dependency between software packages is annoying. During installation, you can select yum to install the oracle-validated package to solve the dependency package of oracle Database software with one click. The following describes

When Oracle and MySQL delete a field, we do not know how many people are aware of the index and constraints. in Oracle, if a composite index is used, it is assumed that the index (a, B, c) three fields are deleted (including unused). how does Oracle handle this index. Similarly, what should Oracle do if it is a constraint?
Using oracle as an example, I made a comparison with mysql to see how mysql handles this problem. I will not discuss who is better or worse, but I hope you will know the diff
In the development and construction of PHP Web site, user registration, message is an essential function, the user submitted information data are submitted through form form, in order to ensure the integrity of the data, security, PHP form form verification is the first link to filter data, PHP to form the data submitted to verify the various ways, Early in the general use of JavaScript to verify PHP forms, with the advent of the WEB2.0 era, taking into account the user experience, using the jqu

The rules section of Yii's models is the validation rules for some forms, useful for form validation, a form is added to the corresponding view (views), and the program is automatically validated in the rules that precede the form submission, and can only be committed if the constraint rules are valid. Can effectively guarantee the safety of forms and the effectiveness of information. Or to give you a specific explanation:
The following is a simple c

For the third and fourth approaches, the solution is as follows:
Add a custom attribute to the form label with Ajax validation control= the "Username,email" property value is the ID of the control to be validated with Ajax (multiple controls are separated by commas).
Copy Code code as follows:

Models are part of the MVC pattern and are objects that represent business data, rules, and logic.
The model is an instance of Cmodel or its subclasses. Models are used to maintain data and the business logic associated with it.
The model is a separate data object. It can be a row in a datasheet, or a form entered by a user. Each field in a data object corresponds to a property in the model. Each attribute has a label, and can be validated by a seri

A full node is a node that maintains a complete block chain containing all the transaction information. More precisely, such a node should be called a full block chain node. In the early days of bitcoin development, all nodes were full nodes, and the current Bitcoin core client was a complete b

Date DatesThis validator checks that the input value is a date, time, or DateTime in a suitable form. Optionally, he can convert the input value into a UNIX timestamp stored in a property specified by Timestampattribute .format: This date/time is a supported format declared in http://php.net/manual
