日期差異和匹配的值在JavaScript中

Question

嗨，我把價值下拉爲「一年」，「兩年」，等等..好嗎？我還有兩個帶日曆擴展器的ajax文本框。如果下拉選擇值爲「一年」，並且兩個文本框值之間的持續時間均表示日期不匹配，我想彈出警報消息。明白我的意思？請幫幫我。 我怎樣才能得到這個場景在JavaScript？

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'); 
    }
