Another newbie question that has me stuck badly.

I have three variables

var state1
var state2
var state3

I need to access one of them on a .click event depending on a property of the clicked object.

How do I access the correct variable? Basically I need to for the variable name by adding "state" and the correct number together.

I will update this post soon with some code in case it's needed.

var backstate1;
var backstate2;
var backstate3;
var currentFrame;
function hotspotHover(){
var currentElement = this;
var daName =this.name;
$("#hotspot" +daName).hover(
 function() { 
 $("img.changeOutline").prop("src", currentElement.outlinesArray[currentFrame]);
 $("#outlines").show(); 
 }, 
 function() { 
 $("#outlines").hide(); 
 }
).click(function() {
 var backstateLevelNumber = currentElement.backStateLevel; //not working
 window['backstate'+ backstateLevelNumber]=currentFrame; //trying to set backstate+number to current frame variable
 hoverClick(currentElement.defaultFrame);
 checkReverse();
 checkSeqLoop();
});
};

Using an array would solve your problem:

var states = [null, null, null];

Accessing them would then be: (Assuming currentStateId being the current state number)

var currentState = state[currentStateId] //Access state

And for setting:

states[currentStateId] = "State"; //Set State

Add the states as an array:

var states = [ 'state1', 'state2'];
var stateNumber = 0;
var state = states[stateNumber];

It could be a proper answer if restated.
Sorry 'bout that. Tries to restate the answer.
What I still don't seem to grasp is how would I then declare a value for the state1 or state2? I'm trying to do basically this: If clicked object has statelevel==1 then modify the value of state1 to be currentFrame.
Can't you use window[ states[number] ] = currentFrame;
