记录前端工作中用的一些常用的函数

// 判断终端
function getTerminal() {
    var ua = navigator.userAgent.toLowerCase();
    if (/iphone|ipad|ipod/.test(ua)) {
        return "ios";
    } else if (/android/.test(ua)) {
        return "android";
    } else {
        return "PC";
    }
}

// 判断是否是微信
function isWeiXin() {
    var ua = window.navigator.userAgent.toLowerCase();
    if (ua.match(/MicroMessenger/i) == 'micromessenger') {
        return true;
    } else {
        return false;
    }
}

//获得地址栏参数
function getQueryString(name) {
    var result = location.search.match(new RegExp("[\?\&]" + name + "=([^\&]+)", "i"));
    if (result == null || result.length < 1) {
        return "";
    }
    return result[1];
}

 

formatDate(weekNum){
      let now=new Date();
      let todayNowTime=now.getTime()% 86400000;
      let todayNowWeekNum=now.getDay();
      if(todayNowWeekNum==0){
        todayNowWeekNum=7;
      }
      let nowWeekMondaySec=(now-todayNowTime-(todayNowWeekNum-1)*86400000)/1000-3600*8;
      nowWeekMondaySec+=86400*weekNum*7;
      let nowWeekMonday=timeHandler.getLocalDateTime(nowWeekMondaySec,"-",10);
      let showWeekLitsClone=[];
      let showWeekStrLits=["周一","周二","周三","周四","周五","周六","周日"];
      for(let i=0;i<7;i++){
        showWeekLitsClone.push({
          dateStr:timeHandler.getLocalDateTime(nowWeekMondaySec+i*86400,"-",10),
          weekStr:showWeekStrLits[i],
          dateStrSec:nowWeekMondaySec+i*86400
        })
      }
      this.showWeekLits=showWeekLitsClone;
    },
