Portal.queryItems callback function execution timing

Hi all,

 

I've got the following scenario...I'm querying my local Portal for certain items and then I am processing them using a callback function, as soon as the query returns them.

 

globalVariable
     //...

     function doSomeOtherStuff() {
          //do some other stuff
          //requires the updated globalVariable
     };

     Portal.queryItems(params).then(processItems)
     
     doSomeOtherStuff();

     function processItems(items) {
          //do something
          //update globalVariable
     };

     //...

 

Giving this is an async call, other things (i.e. doSomeOtherStuff()) carry on while the query is finalised and the items processed.

 

How can I wait for the processItems() to complete before doing anything else (so a synchronous operation in a sense)?

The processItems function updates a global variable that I need to use in doSomeOtherStuff() and carry on with the logic. I can't execute doSomeOtherStuff() within processItems() because due to the nature of it, it will take doSomeOtherStuff() out of scope.

 

Hope this makes sense, I've tried to simplify as much as possible.
