打開food/set.js,添加初始設置

;
var food_set_ops = {
    init:function () {
        this.eventBind();
        this.initEditor();
    },
    eventBind:function () {
        $(".wrap_food_set select[name=cat_id]").select2({
            language: "zh-CN",
            width: '100%'
        });
    },

打開food/set.js,加入事件的绑定到空间

        $(".wrap_food_set input[name=tags]").tagsInput({
            width: 'auto',
            height: 40,
            onAddTag: function (tag) {
            },
            onRemoveTag: function (tag) {
            }
        });

这些都是jquery的插件

封面图片空间无刷上传、展示、删除

form表单不能嵌套form表单,可以将form表单提交到iframe

food/set.html添加iframe

</div>
<iframe name="upload_file" class="hide"></iframe>
{% endblock %}

监控表单change,提交submit事件

food/set.js

 $(".wrap_food_set .upload_pic_wrap input[name=pic]").change(function () {
            $(".wrap_food_set .upload_pic_wrap").submit();
        });

此時 點擊封面圖完成上傳 會post一個請求

後端python文件Upload.py添加upload/pic接口對應

@route_upload.route("/pic",methods = [ "GET","POST" ])
def uploadPic():
    file_target = request.files
    upfile = file_target['pic'] if 'pic' in file_target else None
    callback_target = 'window.parent.upload'
    if upfile is None:
        return "<script type='text/javascript'>{0}.error('{1}')</script>".format( callback_target,"上传失败" )

    ret = UploadService.uploadByFile(upfile)
    if ret['code'] != 200:
        return "<script type='text/javascript'>{0}.error('{1}')</script>".format(callback_target, "上传失败:" + ret['msg'])

    return "<script type='text/javascript'>{0}.success('{1}')</script>".format(callback_target,ret['data']['file_key'] )

运行可以看到返回成功

同時 也報錯 success方法我們還沒有定義

food/set.js添加方法的定義

var upload = {
    error: function (msg) {
        common_ops.alert(msg);
    },
    success: function (file_key) {
        if (!file_key) {
            return;
        }
        var html = '<img src="' + common_ops.buildPicUrl(file_key) + '"/>'
                + '<span class="fa fa-times-circle del del_image" data="' + file_key + '"></span>';

        if ($(".upload_pic_wrap .pic-each").size() > 0) {
            $(".upload_pic_wrap .pic-each").html(html);
        } else {
            $(".upload_pic_wrap").append('<span class="pic-each">' + html + '</span>');
        }
    }
};

common.js添加網址瓶裝的方法

    buildUrl:function (path, params) {
        var url = ''+path;
        var _paramUrl = "";
        if (params) {
            _paramUrl = Object.keys(params).map(
                function (k) {
                    return [encodeURIComponent(k), encodeURIComponent(params[k])].join("=");
                }
            ).join("&")
            _paramUrl = '?'+_paramUrl
        }
        return url +_paramUrl
    },
    buildPicUrl:function( img_key ){
        return 'http://127.0.0.1:8999/static/upload/'  + img_key;
    }

可以看到成功上传并且展示

支持图片删除

food/set.js添加

  var food_set_ops = {
      init:function () {
          this.eventBind();
          this.initEditor();
          this.delete_img();
      },
      eventBind:function () {

           $(".wrap_food_set .upload_pic_wrap input[name=pic]").change(function () {
              $(".wrap_food_set .upload_pic_wrap").submit();
          });

          $(".wrap_food_set select[name=cat_id]").select2({

          $(".wrap_food_set input[name=tags]").tagsInput({

      delete_img: function () {
