JavaScript code to compare fields

Hi AJ,

It's a good question and it relates to the timing of the view-render events.  There's two ways to make it work:

  1. Use the view-render event of the last view to render - this can be inconsistent i think.
  2. Use the scene-render event - always works.  See https://www.knack.com/developer-documentation/#page-render

So your scene-render might look something like:

$(document).on('knack-scene-render.scene_XXXX', function(event, scene) {
    $("#view_1159 .kn-button").on("click", function() {

        var requestedPto = $("#view_1159-field_5").val();
        var availablePto = $("#view_2232-field_1").val();


        if (requestedPto !== availablePto {
            alert ("Don't match");
            return false;
        }
    });
});

And then the next question to ask is whether you can handle this with page rules instead of code?
