}

export function RandomNum(Min, Max) {

// 数字以内的随机数

let Range = Max - Min;

8数组去重

Array.prototype.unique3 = function() {

var json = {};
for(var i = 0; i < this.length; i++) {

}
return res;
}
console.log('数组去重', [1, 2, 12, 2, 1, 12, 2, 12, 3, 4, 6, 3].unique3())

9对数组数字进行排序

function sortNumber(a, b) {
return a - b
}
var arr = [10, 5, 40, 25, 1];

console.log('对数组数字大小进行排序', arr.sort(sortNumber))

10对象排序同时按照两种方式排序。需求是这样的：“active”为1的排在前面，“active”为0的排在后面，然后分别按照“name”的字母顺序进行排序

var arr = [

{
　　"name": "Alfredo",
　　"active": 0
}, {
　　"name": "Alexander",
　　"active": 0
}, {
　　"name": "Ronald",
　　"active": 1
}, {
　　"name": "salvador",
　　"active": 0
}, {
　　"name": "Saryn",
　　"active": 1
}

];

arr.sort(function(a, b) {
　　　　return b.name < a.name;
　　}).sort(function(a, b) {
　　　　return b.active - a.active
　　});
console.log('对象排序', arr)

11时间戳化时间

function formatDuring(mss) {
var days = parseInt(mss / (1000 * 60 * 60 * 24));
var hours = parseInt((mss % (1000 * 60 * 60 * 24)) / (1000 * 60 * 60));
var minutes = parseInt((mss % (1000 * 60 * 60)) / (1000 * 60));
var seconds = parseInt((mss % (1000 * 60)) / 1000);
return hours + "时" + minutes + "分" + seconds + "秒";
}
console.log('时间戳化时间', formatDuring(352425367425))

12设置随机字符

function createVerifyCode() {
var code = '';
var codeLength = 4;
//设置随机字符
　　var random = new Array(0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 'A', 'B', 'C', 'D', 'E', 'F', 'G', 'H', 'I', 'J', 'K', 'L', 'M', 'N', 'O', 'P', 'Q', 'R', 'S', 'T', 'U', 'V', 'W', 'X', 'Y', 'Z');
　　//循环codeLength
　　for(var i = 0; i < codeLength; i++) {
　　　　var index = Math.floor(Math.random() * 36);
　　　　code += random[index];
　　　　}
　　return code;
}
console.log('随机数', createVerifyCode())

13验证手机号邮箱

function isCellphone(value) {
　　var CELLPHONE_REGEXP = /^1[3|4|5|7|8][0-9]{9}$/;
　　value = value.replace(/\s/gi, "");
　　return value && CELLPHONE_REGEXP.test(value);
}

function isEmail(value) {
　　var EMAIL_REGEXP = /^([a-zA-Z0-9]+[_|\_|\.]?)*[a-zA-Z0-9]+@([a-zA-Z0-9]+[_|\_|\.]?)*[a-zA-Z0-9]+\.[a-zA-Z]{2,3}$/;
　　return value && EMAIL_REGEXP.test(value);
}
console.log('手机号', isCellphone('183216500'))
console.log('邮箱', isEmail('98184'))

var arrObj = [{a: 1,c: 2,d: 3}, {a: 2,c: 2,d: 4}]
console.log('筛选数组对象', arrObj.filter(c => c.a == 1))

14存在则去除，不存在则添加

var isExist = false;
var choseTimeNew = [

　　{id: 1,time: '时间1'},

　　{id: 2,time: '时间2'},

　　{id: 1,time: '时间1'}

]
for(var i = 0; i < choseTimeNew.length; i++) {
　　if((choseTimeNew[i].id == 1)) {
　　　　choseTimeNew.splice(i, 1);
　　　　isExist = true;
　　　　break;
　　}
　}
if(!isExist) {
　　　　choseTimeNew.push({id: 3,time: '时间3'});
}
console.log('choseTimeNew', choseTimeNew)

15数组对象去重

var arr2 = [

{
　　name: "name1",
　　num: "1"
},
{
　　name: "name2",
　　num: "11"
},
{
　　name: "name3",
　　num: "12"
},
{
　　name: "name4",
　　num: "13"
},
{
　　name: "name2",
　　num: "1"
},
{
　　name: "name6",
　　num: "12"
}
]

16获取某年某月天数

function getLastDay(year, month) {
　　var new_year = year; //取当前的年份
　　var new_month = month++; //取下一个月的第一天，方便计算（最后一天不固定）
　　if(month > 12) //如果当前大于12月，则年份转到下一年
　　{
　　　　new_month -= 12; //月份减
　　　　new_year++; //年份增
　　}
　　　　var new_date = new Date(new_year, new_month, 1);
　　console.log('new_date', new_date) //取当年当月中的第一天
　　　　return(new Date(new_date.getTime() - 1000 * 60 * 60 * 24)).getDate(); //获取当月最后一天日期
}

17数组累加

console.log('时间', getLastDay('2018', '2')) //28
var arr = [1, 2, 3, 4, 5, 6];
　　console.time("ruduce");
Array.prototype.ruduceSum = function() {
　　for(var i = 0; i < 10000; i++) {
　　return this.reduce(function(preValue, curValue) {
　　console.log(preValue, curValue)
　　return preValue + curValue;
});
}
}
　　arr.ruduceSum();
　　console.log('最终的值：' + arr.ruduceSum()); // 21
　　console.timeEnd("ruduce");
