Good day, not so good in RegEx may be some one could help me.

I've got array = ["5/8 po", "3/4 ts", "1 px", " 1/2" "];

How I could with RegEx convert to array = ["5/8", "3/4", "1", "1/2"];

Value in array could be different.

You can use item.replace(/[a-z]|[A-Z]| /g, '') and map() to get that output array. item.replace(/[a-z]|[A-Z]| /g, '') will replace all the alphabets to blank and you will get the desired output.

var array = ["5/8 po","1px"," 1.2","px 1", "px-1", "i-1/2"];
var res = array.map(item => item.replace(/[a-z]|[A-Z]| /g, ''));
console.log(res);

I need to display only JAR file name so I would like do regex on Array  The regexp.exec(str) method is used for returning a match for the regexp in the string str. The main difference of this method is that it is called on a regexp, not a string. Its behavior is different depending on whether the regexp includes the g flag or not.

You can use this snippet:

var regex = /(?:[1-9][0-9]*|0)(?:\/[1-9][0-9]*)?/g;

var array = ["5/8 po", "3/4 ts", "1 px", "1/2"];

var arrayNumbers = array.map(x => x.match(regex)[0]);

console.log(arrayNumbers);

console.log(arr);

  • You cannot have 5/8 or other fraction values without string representation like "5/8"
  • Sorry I missed strings ))) edit my question.
  • I have also added a answer
  • Damn... the question is totally different now... Please proof read before posting next time.
  • the array you are showing is invalid, there is an error with the last value, because you have more double quotes than expected, so one of them is not beign closed. Also, you should explain better your desired output and input, because there's a lot of answers and for all of them you refuses saying something different
  • Could you please say why we need to use item.split()[0] <== zero ? And please help me with the next in my questions I've got array with " 1/2" ".
  • because split will split the values into two part with the regex /\s+/g which is 5/8 and po so we need the first value of that array so we usesplit()[0]
  • @DevFromEarth I have also updated the answer with more description
  • Yeap, but in my troble we could have something like ["5/8 po","1px"," 1.2" ","px 1", "px-1", "i-1/2"];
  • @DevFromEarth glad to help
  • You all try to use this array = ["5/8", "3/4", "1", "1/2"], But I want to use this one array = ["5/8 po", "3/4 ts", "1 px", " 1/2" "];
  • Yes, i just update the snippet to return the first match :)
  • You all try to use this array = ["5/8", "3/4", "1", "1/2"], But I want to use this one array = ["5/8 po", "3/4 ts", "1 px", " 1/2" "];
  • So, your original array? Then you don't need the regex
