The Dede template can be added with the error picking function. The specific implementation method is as follows: 1. Add an error-picking tag to the template, for example: ``` <p>There are some grammar errors that need to be pointed out in this paragraph:</p> Please point out your mistakes here.</p> ``` 2. You can add some error information such as error type, error prompt, error code, etc. in the error identification tab. 3 Adding the error information to the template's style sheet can be done by adding a CSS-style sheet after the id attribute. For example: ``` Please point out your mistakes here.</p> <style> #Pick the wrong one { color: red; font-size: 15em; text-align: center; } </style> ``` 4. Use javelin code in the template to implement the error detection function. This can be done by adding a javelin code to the id attribute. For example: ``` Please point out your mistakes here.</p> <script> documentgetElementByID(pick error)addEventListener(click function() { varerror = documentgetElementByID(pick error) innerText; <strong></strong><strong></strong> documentgetElementById(message)innerHTML = message; }); </script> ``` In this way, the error picking function could be implemented in the template.
