Solution to UniApp error: 'xxx' form validation failed

When developing UniApp applications, we often encounter form validation problems. When a user submits a form, if the form data does not meet the preset requirements, we need to give a corresponding prompt or reject the submission. However, during actual operation, we sometimes encounter error messages showing that 'xxx' form validation failed. This article will introduce the cause and solution of this error.

First, let’s explore the cause of this error. 'xxx' form validation failed, where 'xxx' represents a field or validation rule in the form. This error usually occurs in form validation functions and means that the field or validation rule did not pass validation.

So, why does the error message of verification failure appear? There are several main reasons:

1. Data type issues: In form validation, we usually set the data type of fields, such as strings, numbers, dates, etc. If the data type entered by the user does not match the setting, an error will be triggered.
2. Required fields: Some fields are required, that is, the user must fill in the content. If the user fails to fill in the required fields, a verification failure error will be triggered.
3. Format issue: Some fields need to meet specific formats to pass verification, such as mobile phone number, email address, etc. If the data format entered by the user does not meet the requirements, an error will be triggered.

Next, let’s solve this problem. Depending on the cause of the error, we can take appropriate measures to resolve the verification failure.

First, we need to check whether the code of the form validation function is correct. In form validation functions, we usually use if statements or regular expressions for verification. Make sure the validation logic is correct and no necessary validation rules are missing.

Secondly, we need to carefully check the data type of the field. Make sure the data type of the field is set correctly and that the data type entered by the user is consistent with the setting. If a data type mismatch is found, we need to adjust the code accordingly or remind the user to enter the correct data type.

In addition, for required fields, we can check before submitting the form. In the click event function of the submit button, we can use the if statement to determine whether the required fields have been filled in. If we find that required fields are not filled in, we can give corresponding prompts and prevent the form from being submitted.

Finally, for format issues, we can use regular expressions for verification. By writing appropriate regular expressions, we can match user-entered data to a set format. If there is no match, corresponding prompt information can be given.

To sum up, to solve the problem of UniApp error: 'xxx' form verification failed, we need to carefully check the code of the verification function, the settings of the verification rules, and the data type and format input by the user. Only by ensuring that these aspects are correct can validation failure errors be avoided. Hope this article helps you solve this problem!
