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: "visible"

通过props传递给子组件的visible，不能在子组件内部修改props中的visible值。

//子  

this.$emit('submit');

 

 

//父

 

    <PlatformDialog

      :visible.sync="dialogVisible"

      v-on:submit="close_dialogVisible"

    ></PlatformDialog>

 

   close_dialogVisible() {

      this.dialogVisible = false;

      this.getList();

    },
