You cannot return a value from a trigger, but you can store information in many different ways, one way is using a object as a parameter:

//event
$("element").on("click", function(event, informationObj) {
       informationObj.userId = 2; //you have to access a propery so you can modify the original object
});
//trigger
var informationObj = {userId : 0};
$("element").trigger("click", [informationObj ]); //informationObj.userId === 2

other way is using jQuerys .data() method

//event
$("element").on("click", function() {
     $(this).data("userId", 2); 
});
//trigger
$("element").trigger("click").data("userId") //2

Another thing you can do is modifying a variable that's declared outside the event and then using it after calling the trigger, or storing it as a property in the element that has the event with the this keyword like this:

//inside the event function
this.userId = 2;

//outside the event
$("element").trigger("click").get(0).userId

Hope it helps.

Edit:

Also, take a look at @Arm0geddon answer below, using .triggerHandler(), just beware that it has some side effects, like not bubbling up the DOM hierarchy.
