HarmonyOS 字符串修改没有生效？

Question

let aaid: string = await AAID.getAAID()
if (aaid) {
  let replacedString = aaid.replace('-','')
  aaid = (replacedString as string).substring(16,8);
  JPushInterface.setAlias(123, userId + aaid)
}

replace方法没有生效，要如何替换或者删除呢？

Answer 1

对于replace方法可以手动实现类似JS提供的replaceAll方法，参考代码如下：

replaceAll(data: string, s1: string, s2: string) {
  return data.replace(new RegExp(s1, "gm"), s2)
}
