})

params:'\'names=\'+names' which is not working properly, how to pass map variable in params of remotefunction and in contoller action how to access that.

Answer 1

Try this:

${remoteFunction({action: "addLabServiceToCountry", controller: "country", params: names});

Then in remoteFunction() you need to iterate through params to get all mapped names.

Or you can convert names to a string:

var namesStr = names.join(',');

and then pass the string:

${remoteFunction({... , params: namesStr});
