• vuedraggable:vue拖拽排序插件


    最近做的项目要用到拖拽排序,我现在的项目是vue项目,所以我就屁颠屁颠的去百度有木有这样功能的插件,我就知道一定会有,那就是vuedraggable,这是一款很棒的拖拽插件,下面我来说一下怎么引入

    首先在vue项目中,用npm包下载下来

    npm install vuedraggable -S

    下载下来后,引入插件,在你的vue文件的script标签里面这样引入

    import draggable from 'vuedraggable'

    别忘了下面要注册组件

    components: {
        draggable
    },

    然后就可以在template标签里面使用了

    单个组件

    <draggable v-model="colors" @update="datadragEnd" :options = "{animation:500}">
                <transition-group>
                    <div v-for="element in colors" :key="element.text" class = "drag-item">
                        {{element.text}}
                    </div>
                </transition-group>
     </draggable>
    

    2个组件左右结构

    <el-row :gutter="24">
                <el-col :span="12">
                  <el-form-item label="对外产品名称">
                    <el-input v-model="proAttribute.description" placeholder="对外产品名称" style=" 250px"></el-input>
                  </el-form-item>
                  <el-form-item label="对外产品属性">
                  <template>
                    <draggable v-model="colors" @update="datadragEnd" :options = "{animation:500}">
                      <transition-group>
                        <div v-for="element in colors" :key="element.text" class = "drag-item">
                          {{element.text}}
                        </div>
                      </transition-group>
                    </draggable>
                  </template>
                  </el-form-item>
                </el-col>
                <el-col :span="12">
                  <el-form-item label="对内产品名称">
                    <el-input v-model="proAttribute.description" placeholder="对内产品名称" style=" 250px"></el-input>
                  </el-form-item>
                  <el-form-item label="对内产品属性">
                  <template>
                    <draggable v-model="colors" @update="datadragEnd" :options = "{animation:500}">
                      <transition-group>
                        <div v-for="element in colors" :key="element.text" class = "drag-item">
                          {{element.text}}
                        </div>
                      </transition-group>
                    </draggable>
                  </template>
                  </el-form-item>
                </el-col>
              </el-row>

    下面贴一下详细用法

    <template>
        <draggable v-model="colors" @update="datadragEnd" :options = "{animation:500}">
                <transition-group>
                    <div v-for="element in colors" :key="element.text" class = "drag-item">
                        {{element.text}}
                    </div>
                </transition-group>
        </draggable>
    </template>
    
    <script>
