报错:The data property “xxxid“ is already declared as a prop. Use prop default value instead

vue.runtime.esm.js:620 [Vue warn]: The data property "xxxId" is already declared as a prop. Use prop default value instead.

这样this.form.传递的Id=this.传递的Id;写是因为如果在组件里面同时在 props 和 data 中定义了 相同名称的变量,就会报错:The data property "xxxid" is already declared as a prop. Use prop default value instead. 因为Vue 规定：不要在组件的 data 中重复声明已经在 props 中定义的属性。
