Differences in IE and FF

This method is very commonly used. For example, you can use it when verifying whether the input date exists. If it is a date that does not exist, its return value will be NaN. In addition, if you want to compare the sequence of two dates, or calculate the number of days that differ between the two dates, you can use it.

This method is very commonly used. For example, you can use it when verifying whether the input date exists. If it is a date that does not exist, its return value will be NaN. In addition, if you want to compare the sequence of two dates, or calculate the number of days that differ between the two dates, you can use it.
Today, I encountered a strange problem when comparing the date sequence using it. It is about the date format. The parse method requires that short dates can be used with "/" or "-" as the separator, but must be represented in the format of month/day/year. For example, today is "7/6/2008" or "7-6-2008". The problem occurs here. When using the format of "7-6-2008", it can be parsed normally in IE, but in FireFox, the return value is always NaN. At first I thought it was a problem with the code, but after checking, I found out that it was the reason for the browser. Later, after changing the format to "7/6/2008", I can parse it normally in IE and FF.

Today I saw a Google Code project called ZeroClipboard, which is the general idea of using flash as a medium to copy the content to the clipboard. This is better than using pure javascript, because different browsers will react differently for security reasons. For example, IE will give a prompt, and some browsers do not support copying to the clipboard.2010-03-03Detailed explanation of the process of converting Baidu map coordinates into Tencent map coordinates
