Description
Technical Field
The invention relates to a computer application technology, in particular to a method for realizing universal form verification, which has a large amount of built-in format verification and can be freely combined to realize a custom verification rule.
Background
The collected data are various physical quantities such as temperature, water level, wind speed, pressure, etc. which have been converted into electrical signals, and may be analog quantities or digital quantities. The acquisition is generally a sampling mode, that is, the same point data is repeatedly acquired at certain time intervals (called sampling period). The acquired data are mostly instantaneous values, but also characteristic values within a certain period of time. Accurate data measurements are the basis for data acquisition. The data measurement method includes contact and non-contact, and the detection elements are various. No matter which method and element, the data correctness is ensured on the premise of not influencing the state of the object to be measured and the measurement environment. The data collection is very broad, and comprises the collection of planar continuous physical quantities. In computer-aided drawing, mapping, designing, the process of digitizing a graphic or image may also be referred to as data acquisition, where geometric (or physical, e.g., grayscale) data is acquired.
Today, the internet industry is rapidly developing, data acquisition is widely applied to the internet and distributed fields, and the data acquisition field is changed significantly. First, intelligent data acquisition systems in distributed control applications have been under great development both at home and abroad. Secondly, the number of bus-compatible data collection cards is increasing, as are the number of data collection systems compatible with personal computers. Various data acquisition machines are published at home and abroad, and bring data acquisition into a brand new era.
With the rapid development of computer networks, a lot of data collection is often accompanied in the interaction process of users and application programs. The form is mainly responsible for data collection in the webpage. The form verification focuses on ensuring that a user submits data in a correct format, namely, input data of a form field in an HTML form is verified, for example, whether the form is necessary to be filled, whether input content is a legal mail address, whether an input format is a number and the like.
And (4) submitting and checking the form, and submitting the data only if the checking condition is met.
The form can set the form verification condition and verify data in the form attribute, and after the flow form starts the flow, the verification condition setting in the form attribute is no longer valid, and the verification condition of the node needs to be set in the flow setting-node attribute-more attribute-node verification condition.
Checking rules
(1) And (4) the condition of writing in the form verification is satisfied, the data can be submitted, and if the condition is not satisfied, the data cannot be submitted. So only the correct conditions need to be written. (2) Checking the input content in the error prompt occurs when the submission condition is not met. (3) Judging the symbol, (4) using the formula, (5) if the form starts the flow, the form verification fails, and the node verification is taken as the standard. In the flow setting-node check, the check of the node needs to be added.
Form verification is an important function in web development, and can ensure that a user submits data in a correct format and ensure that the submitted data can enable an application program to work normally. However, in actual development, the form verification method is too cumbersome.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer and more complete, the technical solutions in the embodiments of the present invention will be described below, it is obvious that the described embodiments are a part of the embodiments of the present invention, but not all embodiments, and all other embodiments obtained by a person of ordinary skill in the art without creative efforts based on the embodiments of the present invention belong to the protection scope of the present invention.
The invention provides a form verification method which has a large number of built-in format verifications and can be freely combined to realize a custom verification rule, which comprises the following steps:
when the built-in format verification is used, the form verification can be directly bound on the element, and a built-in format verification method can be directly introduced, wherein the self-defined format verification supports ajax, logic operation and the like.
When the built-in format is used for verification, a plurality of elements can be directly bound, and input data of the elements are limited and mutual verification rules are made.
The invention provides a universal form verification method, which enables a developer to directly bind elements needing to be verified, defines built-in attributes and methods thereof, customizes verification rules and works out form verification with different functions. The process of the form verification example is mainly divided into the following steps:
firstly, adding a CheckData attribute in an element to be checked;
and secondly, using a built-in check rule in checkData, wherein the check rule can define whether input content is limited to be filled, whether the input content is required to be digital or not, whether a date format is legal or not, the length of the input content, a mailbox format, compared data (which can support ajax, regular operation and the like) and the like.
And thirdly, calling a check function, judging the value in the checkData attribute, carrying out rule check on the form, and considering that the form data is valid for verification through the check.
Step four, calling a unified verification function before the form is submitted, and transmitting the ID of the form to be verified to the function as a parameter; when the verification fails, the function gives a verification prompt and returns false; all form elements are verified before returning true.
A large number of built-in check functions can meet different verification requirements through combination of built-in check rules, and single-element binding verification and establishment of verification rules for limiting multiple elements to each other can be supported.
