Below I am trying to use regex to get the occurrence of certain strings.

(下面，我试图使用正则表达式来获取某些字符串的出现。)

  var value = "ab-2123 AB-332";
  // "i" is for case insensitive
  var regExp = new RegExp("(ab)[-][0-9]*", "gi"); 
  var searchedString = regExp.exec(value);
  console.log(searchedString); 

This only detects ab-2124 but not AB-33 .

(这仅检测到ab-2124 ，而不检测到AB-33 。)

Could some one please help me to figure out the mistake?

(有人可以帮我找出错误吗？)

Answer 1

Firstly, a few important typos corrected

(首先，纠正了一些重要的错别字)

var searchedString regExp.exec(value) should be var searchedString = regExp.exec(value)

(var searchedString regExp.exec(value)应该是var searchedString = regExp.exec(value))

console.log(searched string); should be console.log(searchedString);

(应该是console.log(searchedString);)

regExp.exec() will only return your first match.

(regExp.exec()将仅返回您的第一个匹配项。)

If you want multiple, you could use String.match(regExp)

(如果要多个，可以使用String.match(regExp))

 let value = "ab-2123 AB-332"; let regExp = new RegExp("(ab)[-][0-9]*", "gi"); // "i" is for case insensitive let searchedString = value.match(regExp); console.log(searchedString);
