正则表达式搜索两个字符串之间的内容的字符串 [英] regex search a string for contents between two strings

问题描述

我正在尝试在字符串中搜索文本，我知道字符串如何启动，我知道字符串的结尾，我想返回字符串之间的所有文本，包括开始和结束。

开始搜索= [{lx：

结束搜索= }]

ie

[{lx： variablehere }]

到目前为止我已尝试过

  / ^ \ [\ {lx：（*？）\} \ ] /; 
  

和

  /（\ [\ { LX：）（*）（\} \]）/; 
  

但是没有真正的利用...任何人都可以帮助？

非常感谢

解决方案

你可能会错误地相信 * 是通配符。使用期限（。），你会很好。

另外，你确定要规定零个或多个？如果必须是一个值，请使用+（一个或多个）。

Javascript：

$ {$ {$ {$ {$} $$$ {$$$ ）\} \] /）;

I am trying my upmost best to get my head around regex, however not having too much luck.

I am trying to search within a string for text, I know how the string starts, and i know how the string ends, I want to return ALL the text inbetween the string including the start and end.

Start search = [{"lx":

End search = }]

i.e

[{"lx":variablehere}]

So far I have tried

/^\[\{"lx":(*?)\}\]/;

and

/(\[\{"lx":)(*)(\}\])/;

But to no real avail... can anyone assist?

Many thanks

解决方案

You're probably making the mistake of believing the * is a wildcard. Use the period (.) instead and you'll be fine.

Also, are you sure you want to stipulate zero or more? If there must be a value, use + (one or more).

Javascript:

'[{"lx":variablehere}]'.match(/^\[\{"lx":(.+?)\}\]/);
