In form design, various prompts are mainly used to assist users in completing form filling. 1) Proactive reminder For input information that is open, complex, and beyond the user's cognition, proactive prompts are required. For example, in Alibaba Cloud and Tencent Cloud, many name fields need to start with a letter. In order to facilitate the identification and memory of information, ordinary users are more accustomed to Chinese naming. In this case, the form needs to give filling instructions by default to reduce the user's memory and the probability of errors.
