篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了正则第二次配结果与第一次不一致；正则匹配，第一次匹配结果正常，第二次匹配结果就错误，第三次又正常，第四次又错误，以此类推相关的知识，希望对你有一定的参考价值。
近段时间在项目中使用了银行卡号正则匹配，我在网上搜索了一份银行卡正则包，包含了国内大部分银行卡的正则
然而在遍历正则包校验银行卡号时出现了问题
问题描述：
第一遍调取正则包校验的时候，是可以匹配到相应正则的，但当第二次就匹配不到了，数据和第一遍的一摸一样，如果用户输入了正确银行卡号，当触发第二遍校验时，就抛异常了，那可不行。
然后在网上搜了一下，发现正则有个lastIndex属性，正是这个属性的问题。
正则的lastIndex从字面上来讲就是最后一个索引，实际上它的意思是正则表达式开始下一次查找的索引位置，第一次的时候总是为0的，第一次查找完了的时候会把lastIndex的值设为匹配到得字符串的最后一个字符的索引位置加1，第二次查找的时候会从lastIndex这个位置开始，后面的以此类推。如果没有找到，则会把lastIndex重置为0。要注意的是，lastIndex属性只有在有全局标志正则表达式中才有作用，如果我们把上面代码中正则表达式的g标志去掉，那么三次弹出的就都是true了。（具体详细介绍见文底的参考文档）
修改前代码是这样的：
//验证银行卡号 function bankCardCheck(val) { val = val.replace(/s/g, ""); for (var i = 0, len = bankCardList.length; i < len; i++) { var dataList = bankCardList[i] for (var j = 0, regLen = dataList.patterns.length; j < regLen; j++) { let regular = dataList.patterns[j].reg; let reg = regular.test(val); if (reg) { return true } } } return false }
修改后代码：
//验证银行卡号 function bankCardCheck(val) { val = val.replace(/s/g, ""); for (var i = 0, len = bankCardList.length; i < len; i++) { var dataList = bankCardList[i] for (var j = 0, regLen = dataList.patterns.length; j < regLen; j++) { let regular = dataList.patterns[j].reg; let reg = regular.test(val); if (reg) { regular.lastIndex = 0; //当循环匹配到结果后，将正则的lastIndex赋为0 return true } } } return false }
这样就解决了正则第二次配结果与第一次不一致的问题~

使用方法:
import bankCardCheck from "@u/bankCardList"; let isOk = bankCardCheck(‘6217908000004015662‘) //判断isOk即可 //isOk == true 银行卡号正确 //isOk == false 银行卡号错误
