代码示例：
<html><head><title>Date字符串转化示例</title></head><body><script>var nowDate = new Date("-01-01 11:01:01");window.onload=function(){alert(nowDate.getTime());}</script></body></html>
笔者在web端、android各浏览器测试均无问题但是ios内置的safari浏览器无法识别包含-的日期字符串，返回NAN或null解决方法可通过正则表达式把“-”符号转化为“/”符号 代码示例如下
<html><head><meta http-equiv="Content-Type" content="text/html;charset=utf-8"/><title>Date字符串转化示例</title></head><body><script>var nowDate = "-01-01 11:01:01";nowDate = nowDate.replace(/-/g,"/");window.onload=function(){alert(new Date(nowDate).getTime());}</script></body></html>
