Let us say the a wizard has 5 steps.
Where user goes from step 2 -> step 3, I want to do some activity.
Currently I use e.step.options.index inside onSelect  method to do that.


function onSelect(e) {
    if (e.step.options.index == 3) {
       //do something
    }
}

 

The problem is the "//do something" is also executed when user comes to step 3 from step 4 (step 4 -> step 3).
I do NOT want this to happen. I want to prevent this from happening.

How do I do it?

How do I know which step the user came from?

Hello Azhar,

Here's how you can get the previously selected step's index and use this information to execute your logic only when the user navigates to step 3 from a step with lower index (e.g., 2 to 3):

function onSelect(e) {
  var previousIndex = e.sender.activeStep().options.index;
  var currentIndex = e.step.options.index;

  if (currentIndex == 3 && currentIndex > previousIndex) {
    //do something
  }
}
