#1

var startDt=document.getElementById("startDateId").value;
var endDt=document.getElementById("endDateId").value;

if( (new Date(startDt).getTime() > new Date(endDt).getTime()))
{
    ----------------------------------
}

If you are also using jQuery ui, in particular datepicker, you can use $.datepicker.parseDate(format, string) to turn your date strings into a JavaScript Date object, which you can then compare using the standard < and >

如果您还使用jQuery ui，特别是datepicker，则可以使用$ .datepicker.parseDate（format，string）将日期字符串转换为JavaScript Date对象，然后可以使用标准 <和> 进行比较

#3

var startDate = $('#start_date').val().replace(/-/g,'/');
var endDate = $('#end_date').val().replace(/-/g,'/');

if(startDate > endDate){
   // do your stuff here...
}

#4

just use the jQuery datepicker UI library and convert both your strings into date format, then you can easily compare. following link might be useful

Once you are able to parse those strings into a Date object comparing them is easy (Using the < operator). Parsing the dates will depend on the format. You may take a look at Datejs which might simplify this task.

一旦您能够将这些字符串解析为Date对象，就可以轻松比较它们（使用 <运算符）。解析日期将取决于格式。您可以查看可能简化此任务的datejs。< p>
