How to replace occurrences in string with array values in javascript or jQuery?

Question

I have the following string and array:

var message = 'This is a @[20] very fun, @[75] evening.';
var array_values = {"20": "really", "112": "extreme", "75": "happy"};

How do I replace the @[number] occurrences with the corresponding array values, to get this:

message = 'This is a really very fun, happy evening.';

Thanks!

Answer 1

One way:

var parsed = message.replace(/@\[(\d+)\]/g, function(m, v) {
    return array_values[v] || m;
});

You can do this using replace method:

var message = 'This is a @[20] very fun, @[75] evening.';
var array_values = {"20": "really", "112": "extreme", "75": "happy"};

for( var key in array_values ) {
  if( array_values.hasOwnProperty( key ) ) {
    message = message.replace( '@[' + key + ']', array_values[ key ] );
  }
}

console.log( message );

}
