一、上代码

具体业务代码如下

view class="price-box">
			<text>支付金额</text>
			<text class="price">{{order.payableAmount|addZero }}</text>
		</view>

filters: {
    addZero:function(data){
   
        return data.toFixed(2)
    }
},

如上操作，会出现报错信息如下

vendor.js? [sm]:31 [Vue warn]: Error in render: "TypeError: Cannot read property 'toFixed' of undefined"

二、最终解决如下

特别补充

感谢这位朋友在评论区指正和补充

你好博主，我遇到一个情况，在转换的时候，不是因为空值，而是返回的是字符，用filters转换报错，需要对数据强转一下。toFixed只能针对Number类型才能使用，所以对于字符类型的要用parseFloat或者parseInt函数先转一下再调用
问题截图：

1. [Vue warn]: Error in render: "TypeError: data.toFixed is not a function"
