Question

有人可以帮助我解决以下问题吗？

基本上，我有一个JSON，其中文本带有\n作为换行符。然后，我需要将其解析为markdown并将其转换为HTML。唯一的问题是，我尝试过的所有解析器都会忽略多个\n实例。为了纠正这一点，我想出了以下想法，但是如您所见，它实际上根本不是很适应，而且很笨拙。

var converter = new showdown.Converter(),
description = data.description.replace(/\n\n/g, "\n<br/>\n<br/>");
description = data.description.replace(/\n\n\n/g, "\n<br/>\n<br/>\n<br/>");
description = data.description.replace(/\n\n\n\n/g, "\n<br/>\n<br/>\n<br/>\n<br/>");
var html = converter.makeHtml(description);

有没有办法做到这一点，如果连续有多个\n，它会向每个<br/>附加一个\n？

谢谢：D

编辑：JSON在下面：

{
    "description": "**A glitchy apple respring animation for Anemone.**\n\n\nOriginally requested by u/Cyko__, u/Momoske (Osctardo) decided to make a \"Smoke Ball\" animation for all devices with the 7 different resolutions:\n\n- 1136x640 (iPhone 5s)\n- 1334x750 (iPhone 6/7/8)\n- 1472x828 (iPhone 6/7/8 upscaled)\n- 1920x1080 (iPhone 6+/7+/8+)\n- 2208x1242 (iPhone 6+/7+/8+ upscaled)\n- 2436x1125 (iPhone X)\n- 2688x1242 (iPhone X upscaled)\n\n\nIn the comments of the [UPCOMING] post on r/jailbreak, 2 other people (u/MatRanc and u/R3IZ4) requested for:\n\n- An *\"Apple Glitch\"* respring animation\n- A *\"Verbose\"* respring animation, which was both reworked and updated to look great on all these devices and resolutions\n\n\nThis is the *\"Apple Glitch\"* respring animation, with a black version included for those of you with an OLED device (made by myself)!"
}

编辑2：这是一个jsfiddle，因此您可以看到会发生什么。只需从其中删除.replace()，您就可以看到没有<br/>的HTML应该是什么：https://jsfiddle.net/jacobcxdev/t7hj5mx0/。

Answer 1

当然，您只需要用\ n
替换每个\ n：

{'1': 2, '2': 1, '3': 3, '4': 1, '5': 4}

Answer 2

我设法找到了解决方案！

var converter = new showdown.Converter(),
  description = data.description.replace(/\n{2,}/g, m => m.replace(/\n/g, "<br/>"));
description = description.replace(/<br\/>([^<])/g, "<br\/>\n\n$1");
var html = converter.makeHtml(description);
