Hi Milinda,
It is not a string array, its actually java objects that is there.
Hi Sajith,
I modified the nashorn script as following :
var onRequest = function (context) {
var protocols = callOSGiService("org.wso2.andes.kernel.Andes",
"getSupportedProtocols", []);
var protocolStrings = [];
for each (var item in protocols) {
protocolStrings.push(item.toString());
}
// var protocolsJson = JSON.stringify(protocolStrings);
return {"protocols" : protocolStrings};
};
I am assigning the "protocols" json value to a javascript variable in the
client-side as following :
var protocols =* {{protocols}}*;
$.each(protocols, function(index, value) {
('#queue-subscription-protocols').append($('<option>').text(value).attr('value',
index));
});
But I am getting the following errors when rendered the page(client side
js) :
var protocols = [object Array]; <-- Syntax error
When I use JSON.stringify in server side js, I get the following output :
var protocols =
["AMQP-0-10","MQTT-default","AMQP-0-91","AMQP-8-0","AMQP-0-9"];
<-- Unexpected token &
Any Idea ?
Regards,
Hemika
