<input placeholder="请输入条形码" class="disPriceStyle" v-model = 'searcBarCode'></input>、 （只能输入数字，英文)

<input placeholder="请输入商品条形码" class="disPriceStyle" maxlength="20" v-model = 'searchGoodsName'></input> (只能输入数字，英文及中文)

<input placeholder="请输入活动名称" class="disPriceStyle" maxlength="20" v-model="searchProName"></input> (只能输入数字，英文及中文)

watch:{
   searcBarCode:function(){
    this.searcBarCode=this.searcBarCode.replace(/[\W]/g,'');
   },
   searchGoodsName:function(){
    this.searchGoodsName = this.searchGoodsName.replace(/[^A-Za-z0-9\u4e00-\u9fa5]/g,'');
   },
   searchProName:function(){
