如果是星期天，则看不到每个月的1号 [英] Can't see the 1st in each month, if it is Sunday

问题描述

好，关于日历的最后一个问题(承诺)在 http://testingbar.atspace.com/index2.htm [^ ]

八月从星期日开始.如果按Nästa"直到到达"Augusti"，您将注意到数字1不可见.从星期日开始的每个月都是一样的.但是，如果月份从周末的另一天开始，则看起来正确.如何纠正呢? :confused:

Ok, the last question (promise) about the calendar at http://testingbar.atspace.com/index2.htm[^]

August starts with a Sunday. If you press "Nästa" until you reach "Augusti", then you''ll notice that the number 1 is not visible. It is the same with every month that begins with a Sunday. However, if the month starts with another day in the weekend it looks correct. How to correct this? :confused:

推荐答案

您从何处获得此日历，为什么要要求我们为您重写?答案显然是浏览代码，弄清楚错误是什么，然后修复它.可能是舍入错误吗?

Where did you get this calendar and why are you asking us to rewrite it for you ? The answer is obviously to look through the code, work out what the bug is, and fix it. Could it be a rounding error ?

我认为Date.getDay()函数存在问题.我认为星期日返回0，这可能会影响您的以下逻辑.

我快速浏览并发现了以下内容:

I think it''s a problem with the Date.getDay() function. I believe it returns 0 for sundays which may be throwing your following logic off.

I had a quick look and found this:

Line 89:
firstDay = firstDate.getDay() + 0;

忽略+0绝对无用的事实.您所需要的只是在它下面的行上有一点点条件，例如:

Ignore the fact that +0 is doing absolutely nothing useful. All you need is a little condition on the line underneath it like:

firstDay = ( firstDay == 0 ) ? 7 : firstDay;
