看到这些报错信息,我们顺着去寻找错误,TypeError: Cannot read property 'name' of undefined ,他报的错误类型是TypeError,Cannot read property 'name' of undefined ,说明应该是某个对象的属性name没用定义,at Qe.onShow (http://127.0.0.1:19348/appservice/pages/index/index.js:52:37),紧接着我们在根据这行信息定位错误代码,/pages/index/index.js:52:37,打开index.js查找52行附近的代码,解决问题,OK。
