我正在尝试使用javascript进行简单的客户端验证 - 这将验证NextDate是否大于之前的日期。我正在调用方法onclick =“ValidateEndDate（）;”在我的提交按钮上。但似乎没有用。我需要了解我正在犯的错误。非常感谢你提前。 :)

答案 0 :(得分：1)
我复制了你的代码并稍微改了一下，但是在我的节点命令提示符下运行它，它工作正常，这就是它的外观
function ValidateEndDate() {
var d = new Date();
var EndDate= d;
d.setTime(d.getTime() + 86400000);
var StartDate= new Date();
var sDate = new Date(StartDate);
var eDate = new Date(EndDate);
console.log("Start Date : " + StartDate);
console.log("End Date : " + d);
if(StartDate!= '' && EndDate!= '' && sDate> eDate)
{
console.log("Please ensure that the end Date is greater than Previous Date");
return false;
}
if(StartDate!= '' && EndDate!= '' && sDate < eDate)
{
console.log("Please ensure that the Start Date is greater than Previous Date");
return false;
}
}
ValidateEndDate();
我不确定你为什么不比较EndDate。我也纠正过了。希望它有所帮助。
答案 1 :(得分：0)
此比较取决于输入日期的格式。假设标准格式(YYYY-MM-DD)，您可以这样做：
function ValidateEndDate() {
var StartDate = document.getElementById('ccd_PreviousDate').value;
var EndDate = document.getElementById('ccd_CurrentDate').value;
var eDate = new Date(EndDate);
var sDate = new Date(StartDate);
if (StartDate != '' && StartDate != '' && sDate.getTime() > eDate.getTime()) {
alert("Please ensure that the Next Date is greater than Previous Date");
return false;
}
}
使用.getTime()获取时间戳，然后进行比较。
答案 2 :(得分：0)
var startDate = new Date($('#startDate').val());
var endDate = new Date($('#endDate').val());
if (startDate < endDate){
alert("Please ensure that the Next Date is greater than Previous Date");
}
