百度富文本黏贴图片回调函数处理

处理黏贴图片回调函数 catchremoteimage在 ueditor.all.js文件中的 第23197行

具体逻辑还要参考返回数据格式

  /* 获取源路径和新路径 */
                    var i, j, ci, cj, oldSrc, newSrc, list = info.list;

                    var isAlert = false;

                    for (i = 0; ci = imgs[i++];) {
                        oldSrc = ci.getAttribute("_src") || ci.src || "";
                        for (j = 0; cj = list[j++];)
                        {
                            if (oldSrc == cj.source )
                            {
                                if(cj.state == "SUCCESS") {  //抓取失败时不做替换处理
                                  newSrc = catcherUrlPrefix + cj.url;
                                  domUtils.setAttributes(ci, {
                                    "src": newSrc,
                                    "_src": newSrc
                                  });
                                  break;
                                }
                            } else if (!cj.source){
                                domUtils.setAttributes(ci, {

                                isAlert = true;
                            }
                        }
                    }

                    isAlert ? alert('111') : '';

该函数源码如下，可以复制替换掉，注意修改返回数据格式
