Javascript comparison time size

JS static function date. prase () parameters have strict requirements. Otherwise, the conversion fails.

For example, date. parse ("2000-01-01") IE and Mozilla Browser: "Nan ". Therefore, we generally cannot directly convert the display time on the web page. Processing is required.

Formats that can be directly converted: "01/01/2000", "2000/01/01"

// Define a regular expression, because the JS pair can only replace one

// Convert to "2000/01/01"

VaR regs = new Regexp ("-", "Gi ");

VaR date1 = Document. getelementbyid ("begindate ");

VaR date2 = Document. getelementbyid ("enddate ");

Date1 = date1.replace (regs ,"/");

 

Date2 = date2.replace (regs ,"/");

VaR BD = new date (date. parse (date1 ));

VaR ED = new date (date. parse (date2 ));

BD and Ed are time objects and can be compared directly.
