1. 对于高 index 元素的隐藏 与 显示
-
export const hideIndexEle = (cssStr)=>{
const player = getElementsByCss(cssStr)[0]
if(player){
player.style.position = 'relative'
player.style.top = '9999px'
player.style.marginTop = '9999px'
}
}export const showIndexEle = (cssStr)=>{
const player = getElementsByCss(cssStr)[0]
if(player){
player.style.marginTop = '0'
player.style.top = '0'
}
}
2. 唯一字符串 （参考： https://blog.csdn.net/w405722907/article/details/74375266）
-
export const kjfUUID = (len, radix)=>{
let chars = '0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz'.split('');
let uuid = [], i;
radix = radix || chars.length; if (len) {
// Compact form
for (i = 0; i < len; i++) uuid[i] = chars[0 | Math.random()*radix];
} else {
// rfc4122, version 4 form
let r; // rfc4122 requires these characters
uuid[8] = uuid[13] = uuid[18] = uuid[23] = '-';
uuid[14] = '4'; // Fill in random data. At i==19 set the high bits of clock sequence as
// per rfc4122, sec. 4.1.5
for (i = 0; i < 36; i++) {
if (!uuid[i]) {
r = 0 | Math.random()*16;
uuid[i] = chars[(i === 19) ? (r & 0x3) | 0x8 : r];
}
}
} return uuid.join('');
}
3. 对身份证的月日进行 脱敏
-
export const kjfSafeId = (idStr)=>{
let charArr = idStr.split("")
let result = charArr.reduce((arr, next, index)=>{
(index>9&&index<14)?arr.push("*"):arr.push(next)
return arr
}, [])
return result.join("")
}
