三、使用组件

<div class="maintenance_img mt50 mb50 pl20 pr20" style="font-size: 16px;font-weight: 600;position: relative;">
    <!-- 拖拽 -->
    <SlickList
        :lockToContainerEdges="true"
        lockAxis="x"
        axis="x"
        v-model="maintenanceData.img_list"
        @input="getChangeLists"
        style="display: flex"
        >
        <SlickItem style="z-index: 10000" v-for="(item, index) in maintenanceData.img_list" :index="index" :key="index">
            <div class="maintenance_top">
                <img :src="item" @mouseover="changeMask(index)" @mouseout="changeMask(index)" alt="">
            </div>
        </SlickItem>
    </SlickList>
    <div style="display: flex;position: absolute;bottom: -15px;">
        <div class="maintenance_icon" v-for="(item, index) in maintenanceData.img_list" :key="index">
            <div class="img_bg" :ref="'mask' + index" @mouseover="changeMask(index)" @mouseout="changeMask(index)">
                <Icon @click.stop="isImgShow = true;bigImg = item" class="pointer" size="20" color="#000000" type="md-search" />
                <Icon @click.stop="downloadImg(item)" class="pointer" size="20" color="#000000" type="md-download" />
                <Icon @click.stop="movingItems(4, index)" class="pointer" size="20" color="#000000" type="md-trash" />
            </div>
        </div>
    </div>
    <!-- 600*330 -->
    <div class="add-img" v-if="maintenanceData.img_list.length<5">
        <span>
            <Icon type="md-add" size="30"></Icon>
        </span>
        <p>添加图片</p>
        <input @change="uploadImegs($event, 1)" type="file" accept="image/*" />
    </div>
</div>

    import { SlickList, SlickItem } from "vue-slicksort";
    export default {
        components:{
            SlickItem,
            SlickList
        },
        data() {
            return {
                maintenanceData: {
                    img_list: [], //图片
                },
            }
        },
        created() {

        },
        methods: {
            getChangeLists(vals) {
                // 拖拽完成后返回新的排序数组
                console.log(vals);
            },
        },
    }

.maintenance_top {
    display: flex;
    z-index: 10000;
}
.maintenance_top {
    width: 140px;
    height: 78px;
    border: 1px dashed #ccc;
    border-radius: 6px;
    display: flex;
    align-items: center;
    position: relative;
    margin-right: 15px;

    justify-content: space-evenly;
}

四、组件参数

五、组件方法

HandleDirective

v-handle 指令在可拖动元素内部使用。（即用了这个指令，可以让拖动只在元素的某个位置生效）

Container 必须由 :useDragHandle 属性，且设置为 true 时才能正常工作。

这里有关于此的一个简单元素的例子：

<template>
	<li class="list-item">
	    <!-- 拖动只在 span 元素上生效 -->
	    <span v-handle class="handle"></span>
	    {{item.value}}
	</li>
</template>

<script>
    import { ElementMixin, HandleDirective } from 'vue-slicksort';

    export default {
        mixins: [ElementMixin],
        directives: { handle: HandleDirective },
    };
</script>
