Javascript node.js和ejs变量在页面刷新时不显示
我正在尝试将变量从js传递到.ejs模板文件。这些值在第一次打开页面时出现,但在刷新页面时不显示。当我记录变量时,它们在每次刷新时都会出现在控制台中 ejs: 解决方案: 我为每个firebase查询划分了返回值(如userfb和testInformations),现在正在处理刷新页面Javascript node.js和ejs变量在页面刷新时不显示,javascript,node.js,firebase,ejs,Javascript,Node.js,Firebase,Ejs,我正在尝试将变量从js传递到.ejs模板文件。这些值在第一次打开页面时出现,但在刷新页面时不显示。当我记录变量时,它们在每次刷新时都会出现在控制台中 ejs: 解决方案: 我为每个firebase查询划分了返回值(如userfb和testInformations),现在正在处理刷新页面 var query = firebase.database().ref('/doctors/patients/' + request.id + "/testResults"); query.once("value
