找到问题了
不要在html组件的@回调方法后面中直接使用JSON.stringify的方法
比如下面的写法是错误的

<depos-card  
                @longpress="  
                    moreListShow = true;  
                    oprDepos = item;  
                "  
                v-for="(item, index) in showList"  
                :key="item.depositoryId"  
                :item="item"  
                @goInfo="$common.goUrl('/pages_depos/info/info', { depositoryId: item.depositoryId, fromInfo: JSON.stringify({ organizationId: organization.organizationId }) })"  
                @goProductList="$common.goUrl('/pages_product/list', { depositoryId: item.depositoryId, mode: 1 })"  
></depos-card>

@goInfo方法需要写到方法里
正确的写法像下面这样


        goInfo(item) {  
            this.$common.goUrl('/pages_depos/info/info', {  
                depositoryId: item.depositoryId,  
                fromInfo: JSON.stringify({ organizationId: _this.organization.organizationId || '' })  
            });  
        },

然后再直接回调goInfo的方法

@goInfo="goInfo"

j***@163.com

解决了不能这样写

<tui-form-button background="#f9f9f9" color="#999" borderColor="#999" margin="30rpx 0" @click="priceParse(); $Router.back()">返回</tui-form-button>
