日期差异以及与 javascript 中的值的匹配

Question

您好，我有一个下拉菜单，其值为“一年”、“两年”等。好吧？我还有两个带有日历扩展器的 ajax 文本框。如果下拉列表中选择的值为“一年”并且两个文本框值之间的持续时间意味着日期不匹配，我想弹出警报消息。明白我的意思了吗？请帮我。 我怎样才能在javascript中得到这个场景？

Answer 1

Algorithm :
1.Get the both date from the text box.
2. The find the epcoch time for each date. //
3. subtract the both dates.
4. subtract_result = 365*24*60*60  // Finding the 1 year timestamp values
5. So, it the difference exceed than above calculation , you could sure that the date is mis matching.




Javascript:
    // This is for first date
    first = new Date(2010, 03, 08, 15, 30, 10); // Get the first date epoch object
    document.write((first.getTime())/1000); // get the actual epoch values
    second = new Date(2012, 03, 08, 15, 30, 10); // Get the first date epoch object
    document.write((second.getTime())/1000); // get the actual epoch values
    diff= second - first ;
    one_day_epoch = 24*60*60 ;  // calculating one epoch
    if ( diff/ one_day_epoch > 365 ) // check , is it exceei
    {
    alert( 'date is exceeding one year');
    }
