自己封装的一个js方法用于获取显示的星期和日期时间

/**

 * 获取用于显示的星期和日期时间

 * @param date

 * @returns {string}

 */

function getWeek(date){

    //将字符串日期转换日期对象

    date = date.replace(/-/g, '/');

    var dd = new Date(date);

    var curDate = new Date();

    var curDate2 = new Date();

    var m = dd.getMonth()+1<10?"0"+(dd.getMonth()+1):dd.getMonth()+1;

    var d = dd.getDate()<10?"0"+dd.getDate():dd.getDate();

    var weekday=["周日","周一","周二","周三","周四","周五","周六"];

    var mynum=dd.getDay();

    var week,weekdate;

    var curMd = curDate.getMonth()+1+"-"+curDate.getDate();

    var md = dd.getMonth()+1+"-"+dd.getDate();

    //昨天

    curDate2.setDate(curDate2.getDate()-1);

    var curMd2 = curDate2.getMonth()+1+"-"+curDate2.getDate();

    //时间

    var hour = dd.getHours()<10?"0"+dd.getHours():dd.getHours();

    var minutes = dd.getMinutes()<10?"0"+dd.getMinutes():dd.getMinutes();

    if(curMd == md){

        week = "今天";

        weekdate = hour+":"+minutes;

    }else if(curMd2 == md){

        week = "昨天";

        weekdate = hour+":"+minutes;

    }else{

        week = weekday[mynum];

        weekdate =  m+"-"+d;

    }

    return week+"|"+weekdate;

}

上面的字符串日期对象转换在ios手机上面会有问题，需要通过正则先处理一下，将'-'替换成'/'，如下：

date = date.replace(/-/g, '/');

var dd = new Date(date);
