使用 Vue 单击以编辑文本字段

Question

我正在研究 Vue js，在编辑字段时遇到问题。当我单击一个字段进行编辑时， 所有 可编辑字段都变为活动状态。这是我的代码。

  export default {
        props: ['profileHeight'],

        data() {
            return {
                User: User,
                isEditing: false,
                form:{
                    name:'',
                    email: '',
                },
            };
        },

        mounted() {
        },

        methods: {
            activateInEditMode() {
                this.isEditing = true
            },
            deActivateInEditMode() {
                this.isEditing = false
            }
        }
    }

  <span>Profile settings</span>
                        <p>Full name<span v-on:click="activateInEditMode" v-show="!isEditing">{{User.state.auth.name}}</span>
                            <span v-show="isEditing" >
                             <input v-model="form.name" type="text" class="form-control" >
                            </span>
                        </p>

                        <p>E-mail<span>{{User.state.auth.email}}</span>
                            <span v-show="isEditing" >
                             <input v-model="form.email" type="text" class="form-control" >
                            </span>
                        </p>

尝试使用 focus 和 blur 方法来显示/隐藏表单元素！希望这可以帮助！

new Vue({
  el: '#app',
  data(){
    return {
      user : {
        name: '',
        email: ''
      },
      editField : ''
    }
  },
  methods : {
    focusField(name){
      this.editField = name;
    },
    blurField(){
      this.editField = '';
    },
    showField(name){
      return (this.user[name] == '' || this.editField == name)
    }
  }
})

 <script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.3.4/vue.min.js"></script>
<div id="app">
  <h1>Profile settings</h1>
  <label for="user-name">Full name</label>
  <div class="field">
    <span class="field-value" v-show="!showField('name')" @click="focusField('name')">{{user.name}}</span>
    <input v-model="user.name" v-show="showField('name')" id="user-name" type="text" class="field-value form-control" @focus="focusField('name')" @blur="blurField">
  </div>

  <label for="user-email">Email address</label>
  <div class="field">
    <span class="field-value" v-show="!showField('email')" @click="focusField('email')">{{user.email}}</span>
    <input v-model="user.email" v-show="showField('email')" type="email" class="field-value form-control" @focus="focusField('email')" @blur="blurField">
  </div>
</div>

有许多方法可以做到这一点。我可能会推荐一个组件。

 console.clear()

Vue.component("editable",{
  props:["label", "value"],
  template:`
  <p>
    {{label}}
    <span @click="editing=true" v-show="!editing">
      {{value}}
    </span>
    <span v-show="editing" >
      <input :value="value"
             @input="$emit('input', $event.target.value)"
             @keydown.enter="editing=false"
             type="text"
             class="form-control" >
    </span>
  </p>
  `,
  data(){
    return {
      editing: false,
    }
  }
})

const User = {
  name: 'bob',
  email: '[e-mail]'
}

new Vue({
  el:"#app",

  data() {
    return {
      form: User
    };
  },
})

 <script src="https://unpkg.com/vue@2.2.6/dist/vue.js"></script>
<div id="app">
  <span>Profile settings</span>
  <editable label="Full name" v-model="form.name"></editable>
  <editable label="E-mail" v-model="form.email"></editable>
  <br>
  {{form}}
</div>
