Split String Into Key Value Pair

I want to split the following string by comma if it matches key: value. Split by comma works until it encounters a comma in the value const string = 'country: Kenya, city: Nairobi,

Solution 1:

You could split the string by looking if not a comma follows and a colon.

var string = "country: Kenya, city: Nairobi, population: 3.375M, democracy-desciption: Work in progress/ Not fully met, obstacles exist, foo: bar, bar, bar";

console.log(string.split(/, (?=[^,]+:)/).map(s => s.split(': ')));

.as-console-wrapper { max-height: 100%!important; top: 0; }

Solution 2:

Split into an array of key-value pair strings, then map that array to an array of arrays by splitting each pair:

const table =
 string.split(",") //["key:value","key:value"]
  .map(pair => pair.split(":")); //[["key","value"],["key","value"]]

To built an object out of this:

const result = Object.fromEntries(table);

//usable as:console.log( result.country );

or use a Map:

const result = newMap(table);

//usable as:console.log( result.get("country") );

Solution 3:

try this one...

functiongetParameters() {
    var paramStr = location.search.substring(1).split("&");
    var parameters = {}
    paramStr.map(item=>{
        let keyValue = item.split('=')
        return parameters[keyValue[0]] = keyValue[1];
    })
    return parameters;
}
