字符串不会转换为日期

Question

这里遇到了一个让我发疯的问题。 2个变量被实例化为日期，一个带有字符串，另一个带有硬编码值。如果查看调试窗口，mString的值与硬编码值完全相同，但它会产生无效日期。 不明白为什么，但我肯定会欣赏任何指针。 我正在使用IE 11.它适用于所有其他浏览器

mString的创建方式如下： -

mString = dateParts[2] + "-" + mon.toString() + "-" + dateParts[1]

控制台中的错误与此

无关

这似乎有效，我已经在IE11和Chrome中测试了以下内容，两个警报都适合你吗？

<?xml version="1.0" encoding="utf-8"?>

Answer 2

使用此：

var pattern = /(\d{4})-(\d{2})-(\d{2})/;
var date = new Date(mString.replace(pattern,'$1-$2-$3'));
