Javascript 如果两个平铺字符之间的字符计数大于60，则在两个平铺字符之间添加平铺

我有一个文本字符串，我想在javascript中每隔60个字符通过波浪（~）分割

我有

字符串有许多平铺区域，这很好，很高兴保留它们。但在某些情况下，如果波浪号之间的字符数大于60，我希望通过在第60个字符点添加另一个波浪号来拆分该部分（波浪号到波浪号）。然后重新开始，到下一个瓷砖

基本上，每个瓷砖之间不应超过60个字符，任何少于此字符都可以

最后，我尝试了许多功能

function addtilde(str) {
  var result = '';
  while (str.length > 0) {
    result += str.substring(0, 60) + "~";
    str = str.substring(60);
  }
  return result;
}

没有乐趣，任何想法都会被欣赏。

这里有一个有趣的小递归解决方案。In在字符串上使用方便的

.indexOf

方法，该方法采用第二个参数，指示字符串搜索的起始索引

尚未测试，但应能正常工作。：）

通过调用启动递归

var res = splitItUp("my string", 0);

---

然后返回结果。

对该字符串使用

replace

。它是一个查找“无瓷砖，最多60次，可选后跟瓷砖”的单行程序，并返回非瓷砖部分加上瓷砖

str = str.replace ("([^\~]{1,60})\~?",
    function (fullmatch, partmatch) { return partmatch+'~'; }, "g");

递归执行非常有趣（ES6语法简洁）：

您可以匹配一个正则表达式，其中它匹配从1到n的任意数量的字符，在本例中为60。然后用同样的标记重新加入它
