如何在 JavaScript 中获取特定字符串

Question

I have:

var text = 'LTE CSSR (East xr) (301-LT_King_St_PC)'

and I want to split from (East xr) (301-LT_King_St_PC) only as follow:

var result = text.split('(')
result = (East xr) (301-LT_King_St_PC)

Answer 1

You can use a regular expression with the match function to get this done. Depending on how you want the result try one of the following:

 var text = 'LTE CSSR (East xr) (301-LT_King_St_PC)' console.log('one string:', text.match(/\(.*\)/)[0]) console.log('array of strings:', text.match(/\([^\)]*\)/g))

The first does what you seem to be asking for - a single output of everything between the first ( and the second ). It does this by searching for /\(.*\)/ which is a regex that says "everything in between the parentheses".

The second match splits it into all parenthesised strings using /\([^\)]*\)/g which is a regex that says "each parenthesised string" but the g at the end says "all of those" so an array of each is given.

Answer 2

You can do it using substring() and indexOf() :

 var text = 'LTE CSSR (East xr) (301-LT_King_St_PC)'; var result = text.substring(text.indexOf('(')); console.log(result);

Answer 3

You're quite close with your current method. One way you could try this is to use multiple characters within your split

var result = text.split(") (") 
# Output -> result = ["(East xr", "301-LT_King_St_PC)"]

From here, some string manipulation could get rid of the brackets.

Answer 4

Alternatively you can also use String.match and join its result:

 const text = 'LTE CSSR (East xr) (301-LT_King_St_PC)'; const cleaned = text.match(/\(.+[^\)]\)/).join(` `); console.log(cleaned);
