layui多图上传实现删除功能的方法

在使用layui的多图上传时发现没有删除功能

在网上搜索解决办法时有的感觉太复杂有的不符合自己所需要的所以就自己动手

下面附上代码

HTML:

<div class="layui-upload">
    <button type="button" class="layui-btn" id="test2">多图片上传</button>
    <blockquote class="layui-elem-quote layui-quote-nm" style="margin-top: 10px;width: 88%">
        预览图：
        <div class="layui-upload-list uploader-list" style="overflow: auto;" id="uploader-list">
                                    
        </div>
    </blockquote>
</div>

CSS:

<style type="text/css">
        .uploader-list {
            margin-left: -15px;
        }
 
        .uploader-list .info {
            position: relative;
            margin-top: -25px;
            background-color: black;
            color: white;
            filter: alpha(Opacity=80);
            -moz-opacity: 0.5;
            opacity: 0.5;
            width: 100px;
            height: 25px;
            text-align: center;
            display: none;
        }
 
        .uploader-list .handle {
            position: relative;
            background-color: black;
            color: white;
            filter: alpha(Opacity=80);
            -moz-opacity: 0.5;
            opacity: 0.5;
            width: 100px;
            text-align: right;
            height: 18px;
            margin-bottom: -18px;
            display: none;
        }
 
        .uploader-list .handle i {
            margin-right: 5px;
        }
 
        .uploader-list .handle i:hover {
            cursor: pointer;
        }
 
        .uploader-list .file-iteme {
            margin: 12px 0 0 15px;
            padding: 1px;
            float: left;
        }
    </style>

js:

upload.render({
            elem: '#test2'
            ,url: ''
            ,multiple: true
            ,before: function(obj){
                layer.msg('图片上传中...', {
                    icon: 16,
                    shade: 0.01,
                    time: 0
                })
            }
            ,done: function(res){
                layer.close(layer.msg());//关闭上传提示窗口
                //上传完毕
                $('#uploader-list').append(
                    &#39;<div id="" class="file-iteme">&#39; +
                    &#39;<div class="handle"><i class="layui-icon layui-icon-delete"></i></div>&#39; +
                    &#39;<img style="width: 100px;height: 100px;" src=&#39;+ res.data.src +&#39;>&#39; +
                    &#39;<div class="info">&#39; + res.data.title + &#39;</div>&#39; +
                    &#39;</div>&#39;
                );
            }
        });

$(document).on("mouseenter mouseleave", ".file-iteme", function(event){
            if(event.type === "mouseenter"){
                //鼠标悬浮
                $(this).children(".info").fadeIn("fast");
                $(this).children(".handle").fadeIn("fast");
            }else if(event.type === "mouseleave") {
                //鼠标离开
                $(this).children(".info").hide();
                $(this).children(".handle").hide();
            }
        });

 // 删除图片
        $(document).on("click", ".file-iteme .handle", function(event){
            $(this).parent().remove();  
        });

thinkphp处理上传文件

public function upload(){
        //exit(ROOT_PATH . 'public' . DS . 'uploads');
        // 获取表单上传文件 例如上传了001.jpg
        $file = request()->file('file');
        // 移动到框架应用根目录/public/uploads/ 目录下
        if($file){
            $info = $file->validate(['size'=>2097152,'ext'=>'jpg,png,gif'])->move(ROOT_PATH . 'public' . DS . 'uploads'); //限定2MB
            if($info){
                $src='./uploads/'.str_replace('\\',"/",$info->getSaveName());
                $image = Image::open($src);
                $image->thumb(750, 750)->save($src);//压缩图片大小
                $res['code']=0;
                $res['msg']='上传成功！';
                $res['data']['src']='/uploads/'.str_replace('\\',"/",$info->getSaveName());
                $res['data']['title']=$info->getFilename();
            }else{
                // 上传失败获取错误信息
                $res['code']=1;
                $res['msg']='上传失败！'.$file->getError();
            }
            return $res;
        }
    }
