APP编译后，自定义的属性字段没有被保留，需要怎么处理

<view class="email_center">
<view class="emailLog u-margin-bottom-20">
<u-input

                resource-id="email_addr"  
                accessibility-label="email_input"  
                content-desc="emailaddr"  

                :border="false"  
                :custom-style="customStyle"  
                height="103" type="text"  
                v-model="emailVal"  
                :placeholder="i18n.ess_email"  
                :clearable="false"/>  
            </view>  

我想保存代码中的 resource-id="email_addr"、 accessibility-label="email_input"、 content-desc="emailaddr"属性，需要怎么修改
