Question

我正在尝试找到特定的模式，然后按以下结尾行将文本分割。例如，我的文字看起来与此类似

{11/2/2018 8:09 AM} This item was created by. -John Doe 
{11/2/2018 10:56 AM} This item was upated by -Sue Smith 
{11/2/2018 10:58 AM} Does this item handle multiple lines? 
Yes it does -Jane Sample

我当前正在使用以下javascript

var Notes = data.Notes.split(/-[\w ]+$/gmi);
$.each(Notes, function (index, note) {
    console.log(note)
})

这样做确实很完美，但它会将文本分成几行

{11/2/2018 8:09 AM} This item was created by.

{11/2/2018 10:56 AM} This item was upated by

{11/2/2018 10:58 AM} Does this item handle multiple lines? 
Yes it does

但是您可以看到它删除了用户名...

我该怎么写，以便以该特定模式分割字符串，但将用户名保留在字符串的末尾？

一种方法是使用.match代替.split：

const text = `{11/2/2018 8:09 AM} This item was created by. -John Doe
{11/2/2018 10:56 AM} This item was upated by -Sue Smith
{11/2/2018 10:58 AM} Does this item handle multiple lines?
Yes it does -Jane Sample`;

const notes = text.match(/^[\s\S]*?-[\w ]+$/mg) || [];

for (const note of notes) {
  console.log(note);
}

.split可让您指定要丢弃的内容。 .match可让您指定要保留的内容。在这里，我们要提取尽可能短的文本（[\s\S]*?，直到下次出现名称（-[\w ]+$）为止的文本。

查找模式，然后通过结束新行来拆分
