javascript - 具有多个预览和多个实例的 Uploadcare

Question

如何更改脚本以填充 .seperate-group 中包含的图像的 src，匹配 A 中上传的图像> 与 FOR A 和 B 与 FOR B?

var $ = uploadcare.jQuery;
var widgets = uploadcare.initialize(); // get all widget instances
widgets.forEach(function(widget) {
  widget.onUploadComplete(function(fileInfo) {
    var group = $(widget.inputElement).closest(".group"); // find a group the instance is related to
    $(group).find('.feature-img').each(function(i, img) { // find image tags in the group
      img.src = fileInfo.cdnUrl; // update previews
    });
  });
});

.image-input {
  display: block;
  position: relative;
  height: 100px;
  width: 200px;
}

.container {
  display: flex;
}

.image-preview-wrapper {
  height: 50px;
}

.feature-img {
  height: 100%;
}

.seperate-group img {
  height: 100px;
  width: 100px;
}

Kyle，试试这段代码

var $ = uploadcare.jQuery;
var widgets = uploadcare.initialize(); // get all widget instances
widgets.forEach(function (widget) {
  widget.onUploadComplete(function (fileInfo) {
    var group = $(widget.inputElement).parent().parent(); // find a group the instance is related to
    $(group).find('.feature-img').each(function (i, img) { // find image tags in the group
      img.src = fileInfo.cdnUrl; // update previews
    });
  });
});
