//data:
form: {labels: [{name: ,value: }]
},// methods:
addKey (item) {this.form.labels.push({name: ,value: })
},
removeKey (item, index) {this.form.labels.splice(index, 1)
},注意
核心代码
:proplabels. index .name
:rules{required: true, message: 请输入, trigger: blur}prop里的值有格式要求以本demo为例“表单属性数组key名 ‘.’ 索引值 ‘.’ 数组里对象的key名”rules里填写校验不成功触发条件和提示语
