Vue3 chat record editing: handles conflicts between ID uniqueness and Input display

When developing a chat record editor using Vue3, you often encounter a problem: even if the ID of each record is unique, when you click to edit a different record, the previous edit box will not be automatically closed. This article analyzes this problem and provides solutions.

Goal: When you click on a record to edit, other edit boxes will automatically close to achieve a single editing effect.

Problem analysis:

In existing code, the parent component only sets showeditcontent of the current click record to true , and does not handle the status of other records. Therefore, multiple edit boxes are displayed simultaneously.

Solution:

Modify the processing method of the parent component, and set the editable state of other records to false while setting the current record to set the editable state.

Modified parent component processing method:

 const handleMenuClick = (val: string, dialogData: any) => {
  if (val === '2') {
    showReplyMsg.value = false;
    replyAuthor.value = '';
    showRecords.value = false;
    messageList.value.forEach((item) => {
      item.showEditContent = item.msg_id === dialogData.msg_id;
    });
  }
};

This method traverses messageList , setting only showEditContent of the same record as the click record msg_id to true , and other records to false , ensuring that only one edit box is visible.

Improvement suggestions:

• Use computed properties: You can use computed properties to simplify logic, such as creating a computed property editingMessageId to store msg_id currently being edited, and then determine whether the editing box is displayed based on editingMessageId in the child component.
• v-if optimization: Use v-if="props.dialogdata.showeditcontent && props.dialogdata.msg_id === editingMessageId" in subcomponents to further optimize performance.
• Clearer naming: Use more descriptive variable names, such as isEditing instead of showeditcontent .

Through the above modifications and suggestions, the problem of unique ID but Input display at the same time in Vue3 chat record editing can be effectively solved, and the readability and maintainability of the code can be improved.
