比较cvchtml页面Javascript

Question

MVC5

我希望比较预订的结束日期和开始日期，以找到两者之间的总小时数。日期时间格式为DD / MM / YYYY HH：MM

var hours = (endDate - startDate).TotalHours;
alert('Total Hours Difference ' + hours);

输出显示 “总时差未定义”

工作解决方案

startDate = parseInt(new Date(startDate).getTime() / 1000);
endDate = parseInt(new Date(endDate).getTime() / 1000);
var timeDiff = (endDate - startDate) / 3600;  // will give difference in hrs
alert('Total Hours Differece' + timeDiff);
