Question

您可以在PHP中创建一个后端API，以节省在页面中花费的时间，如下所示，它不依赖于哪个页面，仅基于就绪页面和卸载页面进行计算。$(document).ready(function() {&nbsp; var startPage = new Date();&nbsp; $(window).unload(function() {&nbsp; &nbsp; &nbsp; var leavePage = new Date();&nbsp; &nbsp; &nbsp; var page = (location.pathname+location.search).substr(1);&nbsp; &nbsp; &nbsp; $.ajax({&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; type: 'POST',&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; url: "/api/stayonpage",&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; data: {'timeOnPage': leavePage - startPage, 'page' : page },&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; contentType: 'application/json; charset=utf-8',&nbsp; &nbsp; &nbsp; &nbsp; });&nbsp; &nbsp;});});
