js 如何把字符串转化为日期

Question

字符串格式为 ‘yyyy-mm-dd hh:mi:ss’

Answer 1

js 把字符串转化为日期参考代码如下：var s ='2017-04-18 09:16:15';s = s.replace(/-/g,"/");var date = new Date(s );解释说明：/-/g 是正则表达式表示将所有短横线-替换为斜杠/其中g表示全局替换

Answer 2

var str ='2012-08-12 23:13:15';str = str.replace(/-/g,"/");var date = new Date(str );

Answer 3

function strToDate(str) {var tempStrs = str.split(" ");var dateStrs = tempStrs[0].split("-");var year = parseInt(dateStrs[0], 10);var month = parseInt(dateStrs[1], 10) - 1;var day = parseInt(dateStrs[2], 10);var timeStrs = tempStrs[1].split("-");var hour = parseInt(timeStrs [0], 10);var minute = parseInt(timeStrs[1], 10) - 1;var second = parseInt(timeStrs[2], 10);var date = new Date(year, month, day, hour, minute, second);return date;}
