Replace part of string in a link Javascript

Question

I have the following link:

/v1/catalogue/folders/{catalogueId:[0-9]+}/translations/{translationId:[0-9]+}/

and the following data:

catalogueId: 31
translationId: 4

Now I'd like to change the part between the curly brackets with the value of the data-object. So the link needs to look like this:

/v1/catalogue/folders/31/translations/4/

Is there a way in Javascript to accoomplish this? If yes, what is that way?

Answer 1

This is one of the options:

const regex = /\{(.*?)\}/g
const url = "/v1/catalogue/folders/{catalogueId:[0-9]+}/translations/{translationId:[0-9]+}/"
const replacements = { catalogueId: 19, translationId: 20 } 

const result = url.replace(regex, function(_, segment) {
  return replacements[ segment.split(':')[0] ];
});

Answer 2

see example below

 var data = { catalogueId: 31, translationId: 4, }; var url = $('#mylink').attr('href'); for(var key in data) { var regex = new RegExp('{' + key + '[^}]*}', 'g'); console.log(regex); url = url.replace(regex, data[key]); } console.log(url); $('#mylink').attr('href', url);
