How to loop through a string for a regex match, concat return new full string












1















I'm trying to achieve:



const finalStr = "team='Core', team='Mechanics'"

//loop through string, get single quotes, add <bold>'Core'</bold>

//I want to return the string: 

"team=<bold>'Core'</bold>, team=<bold>'Mechanics'</bold>"


What I've tried, but obviously wrong...can't wrap my head around it:



const finalStr = this.state.finalString

const newFinal = finalStr.match(/'(.*?)'/g).map(item => {

    item = item.replace(item, '<b>' + item + '</b>')

      return item;

    });

    no need to loop, just replace once: replace(/.../g, '<b>$&</b>')

  • Are you trying to generate HTML with that? If so, the correct tag is <b>, not <bold>, as that tag doesn't exist.

You don't need a callback or any additional functions, just use the replacement pattern described in the String.replace() documentation to insert the matched substring ($&). You also don't need the parenthesis for the capture group unless you're intending to do something else with the matches.






const finalStr = "team='Core', team='Mechanics'"



const newFinal = finalStr.replace(/'.*?'/g, '<bold>$&</bold>')

console.log(newFinal)





As a side note, there is no <bold> tag in HTML, so if you are trying to create valid HTML you should be using <b>.

    You could use the same basic regular expression, /'.*?'/gi, with a custom "replacer" callback passed to the string#replace method to solve this:






    const input = "team='Core', team='Mechanics'"
    

    
const output = input.replace(/'.*?'/gi, function(matchStr) {
    

    
  // Wrap each match in the resulting string with <bold /> tags 
    
  return '<bold>' + matchStr + '</bold>';
    
});
    

    
console.log(output);

      The regular expression in the original attempt would capture multi-word items, but using w prevents this, so it won't produce exactly the same results. OP didn't specify that as a requirement, but it might be good to note.

      Nov 13 '18 at 21:26











    • @Herohtar thanks for the feedback - very good point, I'd only paid attention to the input data in the OP and hadn't considered that possibility of white-spaces etc. Thanks again!
