我正在尝试使用jquery来计算页面上的点击次数以及在页面上花费的时间以及跨页面使用会话存储的时间。当用户点击所需的链接时，它会将他们带到反馈页面。
这是我到目前为止的代码：

$("*").click(function(e)
{
// Stop the function propagating up the DOM tree
e.stopPropagation();
// Get the interaction time
eventDate = new Date();
// <p data-islink="islink">dduiduihd</p>
// Check if this is the link we want
if ($(this).data() !== undefined)
{
// The right link has been clicked
benchTime = benchmarkDate();
eDiffpl = eventDate.getTime() - pageLoadDate.getTime() - benchTime;
sessionStorage.myTester = Number(sessionStorage.myTester) + eDiffpl;
// Then move to next page of experiment
window.location.url = "feedback_page.html";
}
else

// An incorrect part of the page has been clicked
sessionStorage.errorCount = Number(sessionStorage.errorCount)++;
console.log(sessionStorage.errorCount);

benchmarkDate（）方法运行end_date = new Date（）999次以获取时间，此时无法更改
