正则表达式匹配星号和换行符之间的字符串

问题描述

示例：

blah blah * Match this text Match this text
            Match this text
            Match this text
            Match this text
            *
more text more text

如何使用换行符从星号内部获取字符串？

推荐答案

您可以在此处使用否定匹配。请注意，我转义 \ 此示例的文字换行符。

You can use a negated match here. Notice that I escaped \ the literal newline for this example.

var myString = "blah blah * Match this text Match this text\
            Match this text\
            Match this text\
            Match this text\
            *\
more text more text";

var result = myString.match(/\*([^*]*)\*/);
console.log(result[1]);

// => " Match this text Match this text            Match this text            Match this text            Match this text            "

如果你不想要前导空格或尾随空格，你可以使用以下内容使它变得非贪婪。

If you don't want the leading or trailing whitespace, you can use the following to make it non greedy.

var result = myString.match(/\*\s*([^*]*?)\s*\*/);
console.log(result[1]);

// => "Match this text Match this text            Match this text            Match this text            Match this text"
