How to display the dates of last week and last month in javascript_javascript skills
The example in this article introduces the implementation code of javascript a week ago and a month ago. It conducts a simple analysis of javascript date processing and shares it with you for your reference. The specific content is as follows

$(function () {
myClick();//点击事件触发
})
//专门包装点击事件；
function myClick() {
$(".tbBtn").click(function () {
var sid = $(this).attr("id");
var agoDate = "";
var Cdate = new Date();
if (sid == "CbtnNull") {
$("#txtCallCycleBegin").val("");
$("#txtCallCyclecurrend").val("");
} else if (sid == "CbtnMoon") {
agoDate = ProcessDate(30);
$("#txtCallCycleBegin").val("{0}-{1}-{2}".format(agoDate.Year, agoDate.Moon, agoDate.Day));
$("#txtCallCyclecurrend").val("{0}-{1}-{2}".format(Cdate.getFullYear(), Cdate.getMonth() + 1, Cdate.getDate()));
} else {
agoDate = ProcessDate(7);
$("#txtCallCycleBegin").val("{0}-{1}-{2}".format(agoDate.Year, agoDate.Moon, agoDate.Day));
$("#txtCallCyclecurrend").val("{0}-{1}-{2}".format(Cdate.getFullYear(), Cdate.getMonth() + 1, Cdate.getDate()));
}
})
}
//处理日期的函数，返回一个字面量；
function ProcessDate(type) {
//1.0获取现在时间的年月日：
var currentTime = new Date("2016-01-02"); //得到当前的时间
var currentYear = currentTime.getFullYear(); //得到当前的年份
var currentMoon = currentTime.getMonth() + 1; //得到当前的月份（系统默认为0-11，所以要加1才算是当前的月份）
var currentDay = currentTime.getDate(); //得到当前的天数
//2.0获取当前时间的一个月内的年月日：（一个月内的大众业务需求为：当前时间的月份-1，当前时间的天数+1）
var agoDay = "";
var agoMoon = currentMoon;
var agoYear = currentYear;
var max = "";
switch (type) {
case 30:
agoDay = currentDay + 1;
agoMoon = currentMoon - 1;
max = new Date(agoYear, agoMoon, 0).getDate(); //获取上个月的总天数
break;
case 7:
agoDay = currentDay - 6;
if (agoDay < 0) {
agoMoon = currentMoon - 1;//月份减1
max = new Date(agoYear, agoMoon, 0).getDate(); //获取上个月的总天数
agoDay = max + agoDay;//天数在上个月的总天数的基础上减去负数
}
break;
}
//3.0对处理的年月日作逻辑判断
//如果beginDay > max（如果是当前时间的天数+1后的数值超过了上个月的总天数： 天数变为1，月份增加1）
if (agoDay > max) {
agoDay = 1;
agoMoon += 1;
}
//如果月份当月为1月的时候， 那么一个月内： 年：-1 月：12 日：依然不变
if (agoMoon == 0) {
agoMoon = 12;
agoYear = currentYear - 1;
}
//4.0对已经处理好的数据作格式处理（单位数则自动补零）
currentMoon = Appendzero(currentMoon);
currentDay = Appendzero(currentDay);
agoMoon = Appendzero(agoMoon);
agoDay = Appendzero(agoDay);
//5.0帮助代码
console.log("当前时间为：{0}-{1}-{2}".format(currentYear, currentMoon, currentDay));
console.log("一个月前的时间为{0}-{1}-{2}".format(agoYear, agoMoon, agoDay));
return { "Year": agoYear, "Moon": agoMoon, "Day": agoDay };
}
//处理各位数为零的数字（单位数则加0）
function Appendzero(obj) {
if (obj < 10) {
return "0" + obj;
} else {
return obj;
}

Getting Started With Chart.js: Pie, Doughnut, and Bubble Charts
Mar 15, 2025 am 09:19 AM
This tutorial will explain how to create pie, ring, and bubble charts using Chart.js. Previously, we have learned four chart types of Chart.js: line chart and bar chart (tutorial 2), as well as radar chart and polar region chart (tutorial 3). Create pie and ring charts Pie charts and ring charts are ideal for showing the proportions of a whole that is divided into different parts. For example, a pie chart can be used to show the percentage of male lions, female lions and young lions in a safari, or the percentage of votes that different candidates receive in the election. Pie charts are only suitable for comparing single parameters or datasets. It should be noted that the pie chart cannot draw entities with zero value because the angle of the fan in the pie chart depends on the numerical size of the data point. This means any entity with zero proportion
