相信在微擎开发的哥们都知道, 微擎在手册方面还是有点坑的,根本不让人活啊.没办法, 开发时, 只能自己看着源码来搞>>>>

好, 不多说了. 现在来看一个坑 ..直接上代码\

html:

<!--自己的头部引入-->
{template 'common_header'}

<script type="text/javascript" src="{$_W['siteroot']}app/resource/js/app/util.js"></script>

    <ul class="report-list white clearfix">

            <div class="pull-left">

                标题

            </div>

            <div class="pull-right">

                <input type="text" placeholder="请输入标题" name="report_title" value="">

        </li>

    </ul>

            <textarea name="textarea" id="textarea" rows="6" placeholder="至少100字" minlength="115" style="color: #333;"></textarea>

            <div class="photo">

                    </div>

                </div>

            </div>

        </div>


    <button type="button" class="submit-report">提交</button>

    <input type="hidden" name="token" value="{$_W['token']}" />

</form>

<script type="text/javascript">

    $(function(){

        mui.init({

            swipeBack: true //启用右滑关闭功能

        });

        //上传图片

        util.image($('.js-image-report_picture'), function(url){

            $('.js-image-report_picture').parent().find('.js-image-preview').append('<input type="hidden" value="'+url.attachment+'" name="report_picture[]" /><img src="'+url.url+'" data-id="'+url.id+'" data-preview-src="" data-preview-group="__IMG_UPLOAD_report_picture" />');

        }, {

            crop : false,//裁剪

            multiple : true,//多图

            preview : '__IMG_UPLOAD_{$name}'//预览

        });

    });

</script>

{template 'common_footer'}

页面图:

上传后再点击删除图片, 使出你的洪荒之力后也是徒然无功:

后来看了源码后, 他这个是用mui封装了 webuploader过来的. 最直接简单粗暴的方法就是自己重新在页面写个删除的操作方法:

//删除图片

        $(document).on("click", ".mui-clearfix .js-submit", function (a) {

            var b = $(document).find(".mui-slider-group .mui-active").index();

            $(".mui-image-preview input").eq(b).remove();

            $(".mui-image-preview img").eq(b).remove();

            var i = mui.previewImage({footer: util.templates["image.preview.html"]});

            i.close();

        });

这样就可以实现了:::
