数据脱敏常用于手机号、身份证号等敏感信息中
方法一：
/**
* 关键信息隐藏
* @param str 字符串
* @param frontLen 字符串前面保留位数
* @param endLen 字符串后面保留位数
* @returns {string}
*/
function hideCode(str, frontLen, endLen) {
var len = str.length - frontLen - endLen;
var xing = '';
for (var i = 0; i < len; i++) {
xing += '*';
}
return str.substring(0, frontLen) + xing + str.substring(str.length - endLen);
};
方法二：
/**
* str:字符串 beginStr:开始位置 endStr:结束位置；
*/
common.desensitization = function(str,beginStr,endStr){
var len = str.length;
var leftStr = str.substring(0,beginStr);
var rightStr = str.substring(endStr,len);
var str = ''
var i = 0;
try {
for (i = 0; i < endStr-beginStr;i++) {
str = str + '*';
}
} catch (error) {
}
str = leftStr + str + rightStr;
return str;
}
方法三：
function desensitization(str, beginLen, endLen){
var len = str.length;
var firstStr = str.substr(0, beginLen);
var lastStr = str.substr(endLen);
var middleStr = str.substring(beginLen, len-Math.abs(endLen)).replace(/[\s\S]/ig, '*');
tempStr = firstStr+middleStr+lastStr;
return tempStr;
}
desensitization('12345678901234',4, -4);
方法四：
数字类型
certificatecodecopy = certificatecode.replace(/^(.{6})(?:\d+)(.{4})$/, "\$1****\$2");
所有类型
enginenocopy = engineno.replace(/^(.{2})(?:\w+)(.{1})$/, "\$1****\$2");
enginenocopy = engineno.replace(/^(.{4})(?:\w+)(.{4})$/, "\$1****\$2");
// vue中使用
<el-table-column
width="200px"
prop="credentialsNum"
label="身份证号码"
align="center"
>
<template slot-scope="scope">
<p v-if="scope.row.credentialsNum != null && scope.row.credentialsNum != '' ">
{{scope.row.credentialsNum.replace(/^(.{6})(?:\d+)(.{4})$/, "$1****$2")}}
</p>
<p v-else>未知</p>
</template>
</el-table-column>
