Flex – What does this ActionScript syntax mean? (Return to the inline syntax)

public function getData(node:Object, model:Object=null):Object
 { 
 if (node ​​is Office) {
 return {children:{label:node.name, label:node.address}};
 }
 }

return {children:{label:node.name, body:node.address}}

 var obj:Object = new Object();
obj.children = new Object();
obj.children.label = node.name;
obj.children.body = node.address ;
return obj;

I am a Java programmer and now need to deal with Flex/ActionScript projects. I got one using Flex 3 Cookbook’s ITreeDataDesriptor example, but there is a line of action script code that is difficult to understand. If anyone can explain this further, I would be grateful.

public function getData( node:Object, model:Object=null):Object
 {
 if (node ​​is Office) {
 return {children:{label:node.name, label:node.address}} ;
 }
 }

The part I don’t understand is “{children:{label:node.name,label:node.address}}”. Office is just one containing two The value object of the String attribute: name and address.

The following return expression (modified from the question)……

< /p>

return {children:{label:node.name, body:node.address}}

…is functionally equivalent to this code…

var obj:Object = new Object();
obj.children = new Object();
obj.children.label = node.name;
obj.children. body = node.address;
return obj;

The anonymous object returned in the problem code complicates the problem because it defines the attribute twice. In this case, use the first Statement, and ignore subsequent statements. No compile-time or runtime errors are thrown.
