js中使用new Date("yyyy-mm-dd hh:mm:ss ")结果为invalid date解决办法

function formatTime(value) {
　　//解决invalid date
    value = value.replace(new RegExp(/-/gm) ,"/");
    var date = new Date(value);
    console.log(date);
    Y = date.getFullYear(),
        m = date.getMonth() + 1,
        d = date.getDate(),
        H = date.getHours(),
        i = date.getMinutes(),
        s = date.getSeconds();
    if(m < 10) {
        m = ‘0‘ + m;
    }
    if(d < 10) {
        d = ‘0‘ + d;
    }
    if(H < 10) {
        H = ‘0‘ + H;
    }
    if(i < 10) {
        i = ‘0‘ + i;
    }
    if(s < 10) {
        s = ‘0‘ + s;
    }
    var t = Y + ‘-‘ + m + ‘-‘ + d + ‘ ‘ + H + ‘:‘ + i + ‘:‘ + s;
    return t;
}
