uniapp普通电商详情页使用富文本

 
		<!-- #ifdef H5||APP-PLUS -->
		<div v-html="formatRichTexts(product.Products_Description)" class="p_detail_des"></div>
		<!-- #endif -->
 
		<!-- #ifdef MP -->
		<rich-text :nodes="product.Products_Description|formatRichText" class="p_detail_des"></rich-text>
		<!-- #endif -->

因为uniapp在h5和app和小程序显示不同所以使用条件编译来适配不同的
