cjl_npm_tools/src/dateFormat.js

提供了关于时间，日期方面的方法，还有像深度拷贝，封装的百度翻译，16进制颜色转换等

//格式化时间
function dateFormat(date){
    const time=new Date(date)
    const y =time.getFullYear()
    const m=padZero(time.getMonth()+1)
    const d=padZero(time.getDate())

    const hh=padZero(time.getHours())
    const mm=padZero(time.getMinutes())
    const ss=padZero(time.getSeconds())

    return `${y}-${m}-${d} ${hh}:${mm}:${ss}`
}

//补零函数
function padZero(n){
    return n > 9 ? n : '0' + n
}

//获取前几天的数据
function GetDateStr(AddDayCount){ 
    var dd = new Date(); 
    dd.setDate(dd.getDate()+AddDayCount);//获取AddDayCount天后的日期 
    var y = dd.getFullYear(); 
    var m = dd.getMonth()+1;//获取当前月份的日期 
    var d = dd.getDate(); 
    //判断 月
    if(m < 10){
        m = "0" + m;
    }else{
        m = m;
    }
    //判断 日n     
    if(d < 10){//如果天数<10
        d = "0" + d;
    }else{
        d = d;
    }
    return y+"-"+m+"-"+d; 
} 

//判断当前时间是否超过设定时间
function timeCompare(time){
	var now = new Date();
	var nowTime = now.getTime();
	var year = now.getFullYear();
	var month = now.getMonth() + 1;//js从0开始取
	var date = now.getDate();
	var deadlineStr = year + "/" + month + "/" + date + " " + time;
	var deadline = Date.parse(deadlineStr);
	if (nowTime > deadline) {
		return true;
	} else {
		return false;
	}
}

//查询今天是周几
function getWeekDay(state){
    var value
	let str='日一二三四五六'
	let weekName=new Date().getDay()
    if(state){
        value = str.charAt(weekName>=6?1:weekName+1);
    }
    else{
        value = str.charAt(new Date().getDay());
    }
    return `周${value}`
}
