待整问题

1、无问题版

<custom-input v-model="searchText"></custom-input>

Vue.component('custom-input', {
  props: ['value'],
  template: `
    <input
      v-bind:value="value"
      v-on:input="$emit('input',$event.target.value)"
    >
  `
})
2、待解决版

<custom-input v-model="searchText"></custom-input>

Vue.component('custom-input', {
  props: ['value'],
  template: `
    <input
      v-model="value"
    >
  `
})

错误:

[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: "value"
