Method and device for validating data on webpage form

Abstract

The embodiment of the invention provides a device and a method for validating data on a webpage form. The device comprises a verifier management module and a script module, wherein the verifier management module is used for managing at least one verifier and maintaining the corresponding relation information between a verifier mark and the verifier; the script module is used for receiving a call request which generates a script code and comprises form domain information of the webpage form, acquiring the verifier relevant to the form domain of the webpage form in verifiers managed by the verifier management module according to the form domain information contained in the call request, obtaining the script code for data validation of a client through using the verifier and outputting the script code used for the client to validate the date in the form domain. By the device and the method, the variance between the validation logics of the client and a server terminal is reduced, thereby the error ratio of a system is reduced.

Description

technical field [0001] The invention relates to the field of network applications, in particular to a method and device for verifying web page form data. Background technique [0002] At present, there are more and more applications based on WEB (web pages). Among these applications, it is very common to use WEB forms to submit data from the client to the server. Submitting data to the server based on a web form generally requires verification of the data entered by the user. Only after the data is verified and valid can the data be further processed. [0003] For example, on a webpage of a registered user, it is required to enter user name, password and other information, where the user name must be a string of more than 6 characters, then when the user submits a registration request after entering 5 characters, the system will give a prompt, Note that the input field of user name must be a string of more than 6 characters. For other input fields, such as passwords, there...

Problems solved by technology

[0009] The server-side validation logic is implemented in the validator, that is, the validation logic of the validator itself, while the logic code for data validation on the client side is generated by the script module through the template according to the validation ID. Since the validation logic code of the client side and The verification logic on the server side is implemented by different objects, that is, the logic implementations of the two are separated, which may easily lead to inconsistencies between the verification logic on the client side and the server side, and the difference in verification logic is large, which will increase the probability of system errors and maintenance cost
