表单验证:多个upload上传图片验证，并且上传成功后清除提示信息

在加上表单验证以后，必填项不填会有提示信息。像一般的input输入框，有正确内容输入后提示信息就会自动消失。但是`el-upload`上传图片以后提示信息依然还在。如下：

![error][]

## 解决方法 ##

在文件上传成功时的钩子函数on-success定义的方法中写一句清除验证器的代码既可以实现。如下代码：  
![代码][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3cxNDE4ODk5NTMy_size_16_color_FFFFFF_t_70]  
验证规则：

![rules][]

上传文件成功的钩子函数定义的方法写上下面关键的一句上传图片后提示信息就已经清除：  
![钩子函数][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3cxNDE4ODk5NTMy_size_16_color_FFFFFF_t_70 1]

![钩子函数][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3cxNDE4ODk5NTMy_size_16_color_FFFFFF_t_70 2]

效果：

![效果][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3cxNDE4ODk5NTMy_size_16_color_FFFFFF_t_70 3]
