js文件引用 utils/first-paint-report.js发布线上后报错，本地开发完全没问题。全是2.10.0版本的。怀疑是不是该版本有问题呢？ 公司自己的监控平台抓获报错如下： [图片] 这个first-paint-report的代码如下： function wxPage (config) { if (!(config.networkId && config.paintId)) { return Page(config); } let modify_wx_page_init_paint_time_start = 0; wxPage.onLoadCalcTime = function (paintId, networkId, time) { if (wx.reportPerformance) { const pages = getCurrentPages(); const current = pages[pages.length - 1]; const path = current && current.route; wx.reportPerformance(paintId, time, `${path}[onLoad]`); // 加载/渲染类，生命周期内耗时 wx.reportPerformance(networkId, time, `${path}[onLoad]`); // 网络类，生命周期内耗时 } } wxPage.onReadyCalcTime = function (paintId, networkId, time) { if (wx.reportPerformance) { const pages = getCurrentPages(); const current = pages[pages.length - 1]; const path = current && current.route; wx.reportPerformance(paintId, time, `${path}[onReady]`); // 加载/渲染类，生命周期内耗时 wx.reportPerformance(networkId, time, `${path}[onReady]`); // 网络类，生命周期内耗时 } } function modifyOnLoad () { modify_wx_page_init_paint_time_start = new Date().getTime(); if (config.onLoad) { config.onLoad.apply(this, arguments); // eslint-disable-line no-invalid-this } } function modifyOnReady () { if (wx.reportPerformance) { const modify_wx_page_init_paint_time_end = new Date().getTime(); const modify_wx_page_init_paint_time = modify_wx_page_init_paint_time_end - modify_wx_page_init_paint_time_start; const pages = getCurrentPages(); const current = pages[pages.length - 1]; const path = current && current.route; wx.reportPerformance(config.paintId, modify_wx_page_init_paint_time, path); // 加载/渲染类，首次渲染时间 wx.reportPerformance(config.networkId, modify_wx_page_init_paint_time, path); // 网络类，首次渲染时间 } if (config.onReady) { config.onReady.apply(this, arguments); // eslint-disable-line no-invalid-this } } const modifyConf = { ...config, onLoad: modifyOnLoad, onReady: modifyOnReady } return Page(modifyConf) } module.exports = wxPage;
