                <span class="uploadimg">
                    <img src="{$data[&#39;savepath&#39;]}" style="max-width: 300px;">
                    <input type="hidden" name="img" value="{$data[&#39;img&#39;]}">
                    <a class="remove-uploadimg" title="删除">✕</a>
                </span>
            </if>
        </p>
        <p class="space-4"></p>
        <p id="imgError" class="msg"></p>
    </p></p>

CSS：

<style>
    .remove-uploadimg{ cursor:pointer;}
    .uploadimg{
        display: inline-block;
        position: relative;
    }
    .uploadimg .remove-uploadimg{
        position: absolute;
        font-size: 20px;
        top:-10px;
        right: -6px;
    }
    .remove-uploadimg{
        width:30px;
        height:30px;
        background-color:#ccc;
        border-radius:50%;
        color:red;
        text-align:center;
    }
    .remove-uploadimg:hover{
        text-decoration: none;
    }</style>

JS：

<script src="__PUBLIC__/js/mbUploadify.js"></script>
<script>    var upload1 = new mbUploadify({
        file: document.getElementById(&#39;imgfile&#39;),        /*ajax 上传地址*/
        url: "{:U(&#39;Upload/mbUploadImg&#39;)}",        //上传进度
        progress: function(){
            $(&#39;#imgpath&#39;).show();
            $(&#39;#imgpath&#39;).val(&#39;上传中...&#39;);
        },        /*上传失败*/
        error: function(file, msg){
            document.getElementById(&#39;imgError&#39;).innerHTML = msg;
        },        /*ajax上传成功*/
        uploadSuccess: function(res){
            $(&#39;#imgpath&#39;).hide();
            $(&#39;#imgpath&#39;).val(&#39;&#39;);            var data = JSON.parse(res);
            document.getElementById(&#39;img-data&#39;).innerHTML = &#39;<span class="uploadimg">&#39; +
                    &#39;<img src="&#39;+ data.savepath +&#39;" style="max-width: 300px;">&#39; +
                    &#39;<input type="hidden" name="img" value="&#39;+data.id+&#39;">&#39;+
                    &#39;<a class="remove-uploadimg" title="删除">✕</a>&#39; +
                    &#39;</span>&#39;;
        }
    });
    $(&#39;body&#39;).on(&#39;click&#39;,&#39;.remove-uploadimg&#39;,function(){
        $(this).parents(&#39;.uploadimg&#39;).remove();
    })</script>

PHP：

public function mbUploadImg(){    $upload = new Upload(); // 实例化上传类
    $upload->maxSize = 5242880 ; // 设置附件上传大小
    $upload->exts = array('jpg', 'gif', 'png', 'jpeg'); // 设置附件上传类型
    $upload->rootPath =  './Public/';    // 上传文件
    $info = $upload->uploadOne($_FILES['files']);    if($info) {        // 上传成功
        $data['name'] = $info['name'];        $data['ext'] = $info['ext'];        $data['type'] = $info['type'];        $data['savename'] = $info['savename'];        $data['savepath'] = "/Public/".$info['savepath'].$info['savename'];        $imgId = M('upload_img')->add($data);        if($imgId){            $resData['code'] = 200;            $resData['msg'] = '成功';            $resData['id'] = $imgId;            $resData['name'] = $data['name'];            $resData['savepath'] = $data['savepath'];            echo json_encode($resData);            return;
        }
    }    // 上传错误提示错误信息
    return $this->ajaxReturn(['code'=>400,'msg'=>$upload->getError()]);
}
