use a data or computed property based on the prop's value

一、问题

[Vue warn]: Avoid mutating a prop directly since the value will be overwritten whenever the parent component re-renders. Instead, use a data or computed property based on the prop's value. Prop being mutated: "dialogVisible"

自定义组件，组件调用了props属性，但父组件修改这个值，就会导致这个错误

二、解决方案

// 新添加
data() {
    return {
      dialogEditVisible: this.dialogVisible
    }
}

// 调用调整成dialogEditVisible
<el-dialog :visible.sync="dialogEditVisible">
