Question

我正在使用ReactJS，并且此成功通知事项未按预期工作。当我裁剪图像并单击“确认裁剪”按钮（如下图所示）时，我得到了“加载程序”加载器，并且在裁剪图像后，它显示“图像已保存”！确认裁切按钮下方的通知。但是我想将“加载和图像保存”放在按钮的侧面，其他人在我之前进行了此工作，但我无法解决。什么可以解决问题？

这是我正在下面处理的表格：

return (
  <form className="form-horizontal" ref="form" onSubmit={this.handleForm}>
    <fieldset>
      <legend>
        {this.state.success === true ? (
          this.props.history.push(`/${serviceId}`)
        ) : this.state.success === false ? (
          <Alert bsStyle="danger">
            <strong>An error occured!</strong>
            <ol>
              {this.state.errorMessages.map((err, index) => (
                <li key={index}>{err.message}</li>
              ))}
            </ol>
          </Alert>
        ) : (
          ""
        )}
      </legend>
      <div className="row-fluid">
        <div className="span5">
          <div
            className={

                : "control-group"
            }
          >

                disabled={this.state.disabled}
                ref={button => {
                  this.submitButton = button;
                }}
              >
                Submit
              </button>
            </div>
          </div>
        </div>
      </div>
    </fieldset>
  </form>
);

现在的样子：

“图像已保存！”从上面的代码可以明显看出，通知也显示在与“加载”相同的位置，我需要在按钮的一侧。

您需要重新构建反应元素，仅此而已。

{this.state.croppedImageUrl ? (
   <div className="flexContainer">
      <button
        className="btn btn-primary"
        type="button"
        onClick={this.handleState}
      >
        Confirm Crop
      </button>

      {this.state.imageFetching && (
            <div className="controls">
              <p className="imageWait">Loading...</p>
            </div>
      )}

      {this.state.showImageSuccess && (
            <div className="controls">
              <p style={{ color: "green" }}>Image Saved! </p>
            </div>
      )}
   </div>
) : null}

注意：我所做的就是：将需要共享相同水平空间的元素包装在一个父div中。

然后在css文件中引入一个类：

.flexContainer {
  display: flex;
  justify-content: space-between;
  align-items: center;
}

这可能会导致按钮和通知之间的间距很大。如果是这样，请尝试在 flexContainer 类的定义中添加max-width: requiredValue;。

在按钮的一侧显示图像裁剪的通知
