校验及数据处理
1、URL校验
// 1.验证url
function isURL(str_url) {
var strRegex = "^((https|http|ftp|rtsp|mms)?://)"
+ "?(([0-9a-z_!~*'().&=+$%-]+: )?[0-9a-z_!~*'().&=+$%-][email protected])?" // ftp的[email protected]
+ "(([0-9]{1,3}\.){3}[0-9]{1,3}" // IP形式的URL- 199.194.52.184
+ "|" // 允许IP和DOMAIN（域名）
+ "([0-9a-z_!~*'()-]+\.)*" // 域名- www.
+ "([0-9a-z][0-9a-z-]{0,61})?[0-9a-z]\." // 二级域名
+ "[a-z]{2,6})" // first level domain- .com or .museum
+ "(:[0-9]{1,4})?" // 端口- :80
+ "((/?)|" // a slash isn't required if there is no file name
+ "(/[0-9a-z_!~*'().;?:@&=+$,%#-]+)+/?)$";
var re = new RegExp(strRegex);
return re.test(str_url);
}
//2.url
//例如http://www.baidu.com
var REG_URL = /^(http?:\/\/)?([\da-z\.-]+)\.([a-z\.]{2,6})([\/\w \.-]*)*\/?$/;
//3.url(不带http/https)
//例如：www.baidu.com
var URL_REG = /^([\da-z\.-]+)\.([a-z\.]{2,6})([\/\w \.-]*)*\/?$/;
2、端口号校验
//验证ip、ip:端口
function testServerList(str){
//IP地址 1.1.1.1
var REG_IPADDR = /^((\d|[1-9]\d|1\d\d|2[0-4]\d|25[0-5])\.){3}(\d|[1-9]\d|1\d\d|2[0-4]\d|25[0-5])$/;
var flag = true;
var arr = str.split(',');
for(var i=0,len=arr.length;i<len;i++){
if(!REG_IPADDR.test(arr[i])){
var arr1 = arr[i].split(':');
if(!REG_IPADDR.test(arr1[0])){
flag = false;
break;
}else {
if(isNaN(arr1[1]) || arr1[1] <= 0 || arr1[1]%1 != 0 || arr1[1] > 65535){
flag = false;
break;
}
}
}
}
return flag;
}
3、数字
//正整数
var NUM = /^[1-9]\d*$/;
//整数
VAR REG = /^([\d]+)$/
//整数和浮点数
var reg = /^\d+(?=\.{0,1}\d+$|$)/;
4、主机名
const hostnameReg = /^(([a-zA-Z]|[a-zA-Z][a-zA-Z0-9-]*[a-zA-Z0-9]).)*([A-Za-z]|[A-Za-z][A-Za-z0-9-]*[A-Za-z0-9])$/im;
5、MAC
方法1：
//mac地址格式
var mac_fro = /^([0-9a-f]{2}:){1,4}\*$/;
var mac_end = /^[A-Fa-f0-9]{1,2}\:[A-Fa-f0-9]{1,2}\:[A-Fa-f0-9]{1,2}\:[A-Fa-f0-9]{1,2}\:[A-Fa-f0-9]{1,2}\:[A-Fa-f0-9]{1,2}$/;
方法2：
const macReg = /^(([a-f0-9]{2}:)|([a-f0-9]{2}-)){5}[a-f0-9]{2}$/im;
6、包含中文
var reg = /[\u4e00-\u9fa5]/
7、是否为日期
isDate: function (s) {
s = sort.trim(s);
var re = /^(([1,2]\d\d\d)-([1-9]|0\d|1[0-2])-([0-9]|[0-2]\d|3[0-1])( ([0,1]\d|2[0-3]):([0-5][0-9]):([0-5][0-9]))*$)/;
return re.test(s);
},
8、是否为时间
isTime: function (s) {
s = sort.trim(s);
var re = /^(\d\d):([0-5][0-9]):([0-5][0-9])$/;
return re.test(s);
},
9、计算字符数
function getStringBytes(str){
if(typeof str !=='string'){
return 0;
}
var length = 0;
var encoder = new TextEncoder();
for(var s of str){
length += encoder.encode(s).length > 1 ? 2 : 1;
}
return length;
}
10、检测字符串是否为空
function isNull(str) {
if (!str)
return true;
else {
switch (typeof(str)) {
case "string": return (/^\s*$/g).test(str);
case "number":
case "boolean":
case "object":
case "function":return false;
}
}
}
11、判对象是否为空
function isEmptyObject(e) {
var t;
for (t in e)
return !1;
return !0
}
12、检查ip范围
function compareIsEqualIp(ipBegin, ipEnd){
var temp1;
var temp2;
temp1 = ipBegin.split(".");
temp2 = ipEnd.split(".");
if(ipBegin === ipEnd) {
top.$.tips("起始IP不能和结束IP一致");
return false;
}
for (var i = 0; i < 3; i++) {
if (parseInt(temp1[i]) != parseInt(temp2[i])){
top.$.tips("前三位必须一致");
return false;
break;
}
}
return true;
}
13、深拷贝
JSON.parse(JSON.stringify(obj))
14、includes(es6)
var arr1 = [{id:2,name:"123"},{id:4,name:"456"}];
var arr2 = ["2"];
var list = arr1.filter(item => !arr2.includes(item.id.toString()));
var arr = list.map(item => item.id);
15、检查2个数组中数否有相同的数据
Array.ExistsSameValues = function(a1, a2) {
var exists = false;
if(a1 instanceof Array && a2 instanceof Array){
for (var i=0,iLen=a1.length; i<iLen; i++){
for (var j=0,jLen=a2.length; j<jLen; j++){
if (a1[i]===a2[j]){
return true;
}
}
}
}
return exists;
};
16、判断一个数组中是否存在重复数据
function isRepeat(arr){
var hash = {};
for(var i in arr) {
if(hash[arr[i]])
return true;
hash[arr[i]] = true;
}
return false;
}
17、数组去重
//方法一
Array.Unique = function(arr){
var newArr = [],
origLen = arr.length,
found,
x, y;
for ( x = 0; x < origLen; x++ ) {
found = undefined;
for ( y = 0; y < newArr.length; y++ ) {
if ( arr[x] === newArr[y] ) {
found = true;
break;
}
}
if ( !found) newArr.push( arr[x] );
}
return newArr;
}
//方法二
function removal(arr){
var res = [];
res = arr.filter(function(item){
return res.filter(d => d.id == item.id)[0] ? '' :res.push(item);
});
return res;
}
//方法三
/**
* 过滤JS数组中的空值，返回新的数组
* @param array 需要过滤的数组
* @returns {Array} []
*/
function clear_arr_trim(array) {
for(var i = 0 ;i<array.length;i++)
{
if(array[i] == "" || typeof(array[i]) == "undefined")
{
array.splice(i,1);
i= i-1;
}
}
return array;
}
18、filter方法
//方法一
var item = subtypelist.filter(function(item, index) {
return item.type == type;
});
//方法二
var item = subtypelist.filter(d => d.type == type)[0].data;
//去掉空数组空字符串、undefined、null
var newArr = arr.filter(item => item);
19、输入start和end 生成一个数组
function makeArr(start,end){
var arr = [];
if(end >= start){
for (var i = start; i <= end; i++) {
arr.push(i)
}
}
return arr
}
20、将端口号中的端口段 改为 端口
function transPort(arr) {
var newArr = [];
if (arr instanceof Array) {
for (var i = 0; i < arr.length; i++) {
if (arr[i].indexOf('-') != -1) {
var arrs = makeArr(arr[i].split('-')[0], arr[i].split('-')[1]);
arr.push(arrs);
arr[i] = '';
}
}
}
// 生成干净的数组
var reg = /[\d\.]+\,([\d\.]+)/g;
newArr = arr.join(",").split(",");
// 去重
newArr = Array.Unique(newArr);
newArr = newArr.sort();
// 去掉第一个空数据
if (newArr[0] == "") {
newArr.shift()
}
return newArr
}
21、IP地址比较大小
function compareIP(ipBegin, ipEnd){
var temp1;
var temp2;
temp1 = ipBegin.split(".");
temp2 = ipEnd.split(".");
for (var i = 0; i < 4; i++) {
if (parseInt(temp1[i])>parseInt(temp2[i])){
return 1;
}else if (parseInt(temp1[i])<parseInt(temp2[i])){
return -1;
}
}
return 0;
}
22、去空格
//左去空格
ltrim: function (s) {
return s.replace(/^\s*/, "");
},
//右去空格
rtrim: function (s) {
return s.replace(/\s*$/, "");
},
//两边去空格
trim: function (s) {
return sort.rtrim(sort.ltrim(s));
}
23、日期转时间戳
function get_unix_time(dateStr) {
if(!dateStr) {
return '';
}
var newstr = dateStr.replace(/-/g, '/');
var date = new Date(newstr);
var time_str = date.getTime().toString();
return time_str.substr(0, 10);
}
24、时间戳转日期
function formatDate(tm) {
if(tm == 0 || tm == '0' || !tm || tm == '')
{
return '';
}
var now = new Date(parseInt(tm) * 1000),
year = now.getFullYear(),
month = now.getMonth() + 1,
date = now.getDate(),
hour = now.getHours(),
minute = now.getMinutes(),
second = now.getSeconds();
month = month < 10 ? '0' + (month) : month;
date = date < 10 ? '0' + (date) : date;
hour = hour < 10 ? '0' + (hour) : hour;
minute = minute < 10 ? '0' + (minute) : minute;
second = second < 10 ? '0' + (second) : second;
return year + "-" + month + "-" + date + " " + hour + ":" + minute + ":" + second;
}
25、时间戳转当日零点起的日期
function formatDateCur(timestamp) {
var now = parseInt(timestamp);
var hour = parseInt(now / 3600);
var minute = parseInt((now - 3600 * hour) / 60);
var second = now - 3600 * hour - 60 * minute;
hour = hour < 10 ? '0' + (hour) : hour;
minute = minute < 10 ? '0' + (minute) : minute;
second = second < 10 ? '0' + (second) : second;
return hour + ":" + minute + ":" + second;
}
26、日期转当前日期零点起的时间戳
function formatDateUnixCur(time) {
var arg=time.split(":");
var t1 = parseInt(arg[0]) * 3600;
var t2 = parseInt(arg[1]) * 60;
var t3 = parseInt(arg[2]);
var times = t1+t2+t3;
return times;
}
27、日期字符串转正常日期格式
function formatDateTime(tm) {
var time = '';
if(tm)
{
time = tm.substr(0,4) + '-'
+ tm.substr(4,2)+ '-'
+ tm.substr(6,2)+ ' '
+ tm.substr(8,2)+ ':'
+ tm.substr(10,2)+ ':'
+ tm.substr(12,2);
}
return time;
}
28、格式化浏览器转义字符
function formatEncodeHtml(value, row, index) {
var s = value;
var REGX_HTML_ENCODE = /"|&|'|<|>|[\x00-\x20]|[\x7F-\xFF]|[\u0100-\u2700]/g;
return (typeof s != "string") ? s :
s.replace(REGX_HTML_ENCODE,
function ($0) {
var c = $0.charCodeAt(0), r = ["&#"];
c = (c == 0x20) ? 0xA0 : c;
r.push(c);
r.push(";");
return r.join("");
});
}
29、其他校验
const ipv4Reg = /^(([0-9]|[1-9][0-9]|1[0-9]{2}|2[0-4][0-9]|25[0-5])\.){3}([0-9]|[1-9][0-9]|1[0-9]{2}|2[0-4][0-9]|25[0-5])$/im;

30、根据某个属性给object数组进行排序
function keyNameSort(keyName){
return function (obj1,obj2){
var v1 = obj1[keyName];
var v2 = obj2[keyName];
if(v1>v2)return 1;
else if(v1==v2)return 0;
else return -1;
}
}
function foo(arr,keyName){
arr.sort(keyNameSort(keyName));
}
31、利用JavaScript打印出Fibonacci数（不使用全局变量
(function () {
var outLength = 20, nowValue = 0, prevValue = 1, swapValue;
for (var i = 1, len = outLength - 1; i < len; i++) {
if (i < 3) {
nowValue = 1;
} else {
swapValue = nowValue + prevValue;
prevValue = nowValue;
nowValue = swapValue;
}
console.log(nowValue)
}
}())
32、数组搜索查询某个str
function searchList(str, list) {
var arr = [];
if(str){
if(list.length > 0){
for(var i=0,len=list.length;i<len;i++){
if(list[i]){
var item = list[i];
if(item.label.toLowerCase().indexOf(str.toLowerCase())> -1){
arr.push(item);
}
}
}
}
}
return arr;
}
33、以天时分的格式计时
//计算差值----毫秒数
var haveTime =(new Date()) - (new Date("2018-05-25 20:35:48"));
//将时间戳转为天时分格式
function getTimer(haveTime){
var days = parseInt(haveTime / 1000 / 60 / 60 / 24 , 10); //计算上线的天数
var hours = parseInt(haveTime / 1000 / 60 / 60 % 24 , 10); //计算上线的小时
var minutes = parseInt(haveTime / 1000 / 60 % 60, 10);//计算上线的分钟
// var seconds = parseInt(haveTime / 1000 % 60, 10);//计算上线的秒数
days = checkTime(days);
hours = checkTime(hours);
minutes = checkTime(minutes);
// seconds = checkTime(seconds);
return days+"天" + hours+"小时" + minutes+"分";
}
function checkTime(i){ //将0-9的数字前面加上0，例1变为01
if(i<10)
{
i = "0" + i;
}
return i;
}
//从元素获取值（天时分），以天时分的格式计时并赋值给该元素
function setTiem() {
$('tbody tr td:last-child').each(function(index,item){
var strTiem = $(item).text();
if(strTiem){
var days = parseInt(strTiem.slice(0,2));
var hours = parseInt(strTiem.slice(3,5));
var minutes = parseInt(strTiem.slice(7,9));
minutes++;
if(minutes >= 60){
minutes = 0;
hours ++;
}
if(hours >= 24){
hours = 0;
days ++;
}
days = checkTime(days);
hours = checkTime(hours);
minutes = checkTime(minutes);
$(item).text(days+"天" + hours+"小时" + minutes+"分");
}
})
}
