1、要实现的效果图

2、div代码

<div id="ddd">
    <div id="img-group">
        <div class="img-item" v-for="item in imgArr">
            <img :src="item.src" alt="">
        </div>
    </div>
    <div class="add-pic" @click="addPic()" v-show="picFlag">+
        <input name="files" id="uploaderInput" type="file" accept="image/*" multiple/>
    </div>
</div>

3、方法和数据

data(){
    return {
        imgArr: [],
        picFlag: true
    }
},
methods: {
    goBack(){
        history.go(-1)
    },
    addPic(){
        var vm = this;
        var input = $("#uploaderInput");
        input.unbind('change').on('change', function (e) {
            var files = input[0].files;
            if (files.length == 6) vm.picFlag = false;
            for (var i = 0; i < files.length; i++) {
                var reader = new FileReader();
                reader.readAsDataURL(files[i]);
                reader.onload = function () {
                    if (vm.imgArr.length < 6) {
                        vm.imgArr.push({src: this.result});
                    }
                    if (vm.imgArr.length == 6) vm.picFlag = false
                    if (vm.imgArr.length > 6) {
                        Toast({
                            message: '您最多上传六张站点图片',
                            position: 'bottom',
                            duration: 2000
                        });
                        vm.picFlag = false
                    }

                };
            }
        });
    },
},

4、css代码

.hide {
    display: none;
}

.img-item {
    width: 4.4rem;
    height: 3.75rem;
    float: left;
    margin-left: 1.5rem;
    margin-top: 0.5rem;
}

.img-item img {
    width: 100%;
    height: 100%;
}

.active-pic {
    font-size: 0.6rem;
    color: #9b9b9b;
    padding: 0 1rem 0 1.5rem;
    margin-top: 1rem;
}

.add-pic {
    background: #f3f3f3;
    width: 4.4rem;
    height: 3.75rem;
    float: left;
    margin-left: 1.5rem;
    margin-top: 0.5rem;
    text-align: center;
    font-size: 2rem;
    line-height: 3.5rem;
    color: #979797;
    position: relative;
}

.add-pic input {
    position: absolute;
    left: 0;
    top: 0;
    width: 100%;
    height: 100%;
    z-index: 10;
    opacity: 0;
}
