UI frame table dynamic add/subtract form entries have holes!

Pit:

The data in this table:model=”dynamicValidateForm”And <el-form-item v-for=”(domain, index) in dynamicValidateForm.domains” :label=”‘ domains’ + index” :key=” domains. Key “></el-form-item> , must be preceded by dynamic, otherwise the page does not have the DESIRED DOM structure!

As shown in figure:

The simple understanding is:

If the binding value is addForm, it has no effect and the binding value is changed

dynamicAddFormIt works!

I stepped in this hole while working on a project today! Dozens of minutes!!
