过滤文字
判断名字小于10个就为空。否则就显示三个点

<div class="goods_title">{{product_name | nameFilter}}</div>
<div class="goods_title2">{{sku_name | nameFilter}} {{specification_item_names?specification_item_names:'' | nameFilter}}</div>

  filters:{
    nameFilter(name){
        if(name.length<10){
            return name
        }else{
            return name.substring(0,9)+'...'
        }
    }  
  },

手机号脱敏

<div>手机号码 {{ phonenum | phonenumEncryption }}</div>

filters: {
        //手机号脱敏显示
        phonenumEncryption(val) {
            return val.substr(0, 3) + '****' + val.substr(7, 11);
        }
    },
