new Date() using Javascript in Safari
提问by Dodinas
I'm having an issue using the new Date() function in Javascript. Safari is giving me an "Invalid Date" message.
我在 Javascript 中使用新的 Date() 函数时遇到问题。Safari 给我一条“无效日期”消息。
I've created a short example at jsbin.
我在jsbin创建了一个简短的例子。
This appears to work on all other browsers, but not Safari. Any ideas on how I can take the value from an input (such as 2011-01-03) and turn it into a date object, while having it work properly in Safari?
这似乎适用于所有其他浏览器，但不适用于 Safari。关于如何从输入（例如 2011-01-03）中获取值并将其转换为日期对象，同时使其在 Safari 中正常工作的任何想法？
Many thanks!
非常感谢！

The date parsing behavior on JavaScript is implementation-dependent, the ISO8601 format was recently added to the ECMAScript 5th Edition Specification, but this is not yet supported by all implementations.
JavaScript 上的日期解析行为取决于实现，最近将 ISO8601 格式添加到 ECMAScript 第 5 版规范中，但并非所有实现都支持这种格式。
I would recommend you to parse it manually, for example:
我建议您手动解析它，例如：
function parseDate(input) {
var parts = input.match(/(\d+)/g);
return new Date(parts[0], parts[1]-1, parts[2]);
}
parseDate('2011-01-03'); // Mon Jan 03 2011 00:00:00
Basically the above function matches each date part and uses the Date constructor, to build a date object, note that the monthsargument needs to be 0-based (0=Jan, 1=Feb,...11=Dec).
基本上，上面的函数匹配每个日期部分并使用 Date 构造函数来构建日期对象，请注意月参数需要基于0 (0=Jan, 1=Feb,...11=Dec)。

The easy solution I tried Download date.js from http://datejs.com/Include in your file
我尝试过的简单解决方案 从http://datejs.com/下载 date.js 包含在您的文件中
then var date = Date.parse('1970-01-12 00:00:00'); var formattedDate = date.toString('yyyy-MM-dd');
然后 var date = Date.parse('1970-01-12 00:00:00'); var formattedDate = date.toString('yyyy-MM-dd');

While @CMS's solution is probably superior, I found that using Date.parse('2011-01-13')is also a quick, working solution.
虽然@CMS 的解决方案可能更胜一筹，但我发现使用Date.parse('2011-01-13')也是一种快速有效的解决方案。

csnover has some progressive ISO 8601 Date enhancement code available on GitHub: https://github.com/csnover/js-iso8601/blob/master/iso8601.js
csnover 在 GitHub 上提供了一些渐进式 ISO 8601 日期增强代码：https: //github.com/csnover/js-iso8601/blob/master/iso8601.js
Including his code should provide a temporary fix while the Safari team work toward a more complete ES5 implementation.
在 Safari 团队努力实现更完整的 ES5 实现时，包含他的代码应该会提供一个临时修复。
