The search () method searches a string for a specified value, and returns the position of the match. The search value can be string or a regular expression. This method returns -1 if no match is found. Read more about regular expressions in our RegExp Tutorial and our RegExp Object Reference.

True or false /^(?=.*status~contains~(true|false)).*/ Use the multi-line option and group 1 is the value.

Dot. Match 0 or more of the preceding token. But, here is one that will match anything in a string that is between id and id: var regex = /id.*id/; Here’s the breakdown ( the / and / are like quotes for a string and are not part of the regex):

/(?<=status~contains~)[^~)]+(?=[~)])/g

This uses a lookbehind of: status~contains~ and a lookahead of either ~ or ). Therefore we can match 1 or more characters that are neither ~ nor ) between the lookbehind and lookahead. This is simpler and more efficient than using .*?.

let re = /(?<=status~contains~)[^~)]+(?=[~)])/g;
let text = "(username~contains~'ren'~and~status~contains~false)" +
           "(status~contains~false~and~username~contains~'ren')";
let m;
while (m = re.exec(text))
    console.log(m[0]);

string between two strings, You can use the JavaScript match() method to extract substring between two the two words using the match() method and a simple regular expression pattern. When you want to know whether a pattern is found, and also know its index within a string, use search (). (If you only want to know if it exists, use the similar test () method on the RegExp prototype, which returns a boolean.) For more information (but slower execution) use match () (similar to the regular expression exec () method).

  • the first example looks good, but the second without lookbehind don't pass, test it in reg site
  • @Jhonny In the second example the value is in the first capturing group. This is an example with a different engine selected which will highlight the groups in green. regex101.com/r/YNLdOO/1 You can get those matches using the example Javascript and it does not use lookarounds.
  • ooh, thanks for the explication. i will accept your answer because is the most explained
