vue实现双击编辑

实现双击编辑功能的基本思路

在Vue中实现双击编辑功能，通常需要以下核心逻辑：监听元素的dblclick事件，切换显示状态（文本展示/输入框编辑），并在失去焦点或按下回车时保存修改。

vue实现双击编辑

基础实现示例

<template>
  <div>
    <span v-if="!isEditing" @dblclick="startEditing">{{ content }}</span>
    <input
      v-else
      ref="input"
      v-model="editingContent"
      @blur="saveEdit"
      @keyup.enter="saveEdit"
    />
  </div>
</template>

<script>
export default {
  data() {
    return {
      content: '双击编辑这段文字',
      isEditing: false,
      editingContent: ''
    }
  },
  methods: {
    startEditing() {
      this.isEditing = true
      this.editingContent = this.content
      this.$nextTick(() => {
        this.$refs.input.focus()
      })
    },
    saveEdit() {
      this.content = this.editingContent
      this.isEditing = false
    }
  }
}
</script>

进阶优化方案

将编辑逻辑封装为可复用组件：

vue实现双击编辑

<!-- EditableText.vue -->
<template>
  <div class="editable-text">
    <span v-if="!editing" @dblclick="startEdit">{{ value }}</span>
    <input
      v-else
      ref="input"
      v-model="tempValue"
      @blur="finishEdit"
      @keyup.enter="finishEdit"
      @keyup.esc="cancelEdit"
    />
  </div>
</template>

<script>
export default {
  props: {
    value: {
      type: String,
      required: true
    }
  },
  data() {
    return {
      editing: false,
      tempValue: ''
    }
  },
  methods: {
    startEdit() {
      this.editing = true
      this.tempValue = this.value
      this.$nextTick(() => this.$refs.input.focus())
    },
    finishEdit() {
      this.$emit('input', this.tempValue)
      this.editing = false
    },
    cancelEdit() {
      this.editing = false
    }
  }
}
</script>

支持多种元素类型

扩展组件以支持input、textarea或自定义组件：

<template>
  <div>
    <component
      :is="displayComponent"
      v-if="!editing"
      @dblclick="startEdit"
    >{{ value }}</component>

    <component
      :is="editComponent"
      v-else
      ref="input"
      v-model="tempValue"
      @blur="finishEdit"
      @keyup.enter="finishEdit"
    />
  </div>
</template>

<script>
export default {
  props: {
    value: String,
    displayComponent: {
      type: String,
      default: 'span'
    },
    editComponent: {
      type: String,
      default: 'input'
    }
  }
  // ...其余逻辑同上
}
</script>

添加样式和过渡效果

增强用户体验的视觉反馈：

.editable-text {
  position: relative;
}

.editable-text span {
  padding: 2px 5px;
  border-radius: 3px;
  cursor: text;
}

.editable-text span:hover {
  background: #f0f0f0;
}

.editable-text input {
  border: 1px solid #ddd;
  padding: 3px 5px;
  width: 100%;
  box-sizing: border-box;
}

.fade-enter-active, .fade-leave-active {
  transition: opacity 0.2s;
}
.fade-enter, .fade-leave-to {
  opacity: 0;
}
