I have example string:
[:pl]Field_value_in_PL[:en]Field_value_in_EN[:]
And I want get something like it:
Object {
pl: "Field_value_in_PL",
en: "Field_value_in_EN"
}
But I cannot assume there will be always "[:pl]" and "[:en]" in input string. There can by only :pl or :en, :de and :fr or any other combination.
I tried to write Regexp for this but I failed.
Try using .match() with RegExp /:(\w{2})/g to match : followed by two alphanumeric characters, .map() to iterate results returned from .match(), String.prototype.slice() to remove : from results, .split() with RegExp /\[:\w{2}\]|\[:\]|:\w{2}/ to remove [, ] characters and matched : followed by two alphanumeric characters, .filter() with Boolean as parameter to remove empty string from array returned by .split(), use index of .map() to set value of object, return object
var str = "[:pl]Field_value_in_PL[:en]Field_value_in_EN[:]:deField_value_in_DE";
var props = str.match(/:(\w{2})/g).map(function(val, index) {
var obj = {}
, prop = val.slice(1)
,vals = str.split(/\[:\w{2}\]|\[:\]|:\w{2}/).filter(Boolean);
obj[prop] = vals[index];
return obj
});
console.log(JSON.stringify(props, null, 2))Solution with String.replace , String.split and Array.forEach functions:
var str = "[:pl]Field_value_in_PL[:en]Field_value_in_EN[:fr]Field_value_in_FR[:de]Field_value_in_DE[:]",
obj = {},
fragment = "";
var matches = str.replace(/\[:(\w+?)\]([a-zA-Z_]+)/gi, "$1/$2|").split('|');
matches.forEach(function(v){ // iterating through key/value pairs
fragment = v.split("/");
if (fragment.length == 2) obj[fragment[0]] = fragment[1]; // making sure that we have a proper 'final' key/value pair
});
console.log(obj);
// the output:
Object { pl: "Field_value_in_PL", en: "Field_value_in_EN", fr: "Field_value_in_FR", de: "Field_value_in_DE" }

You can try this regex to capture in one group what's inside a pair of brackets and in the other group the group of words that follow the brackets.
(\[.*?\])(\w+)
