Below is an sample of decision making for the progression onto the next wizard page based on a radio button input. This could be easily adaptable for any other type of fields.
The wizard pages are referenced by name in the code.
$.njDialerPlugin.getPage('${NjWizardPageName}').onPageNext = function(page,defaultNextPage) {
// default to stay on current page if no button selected
var nextPage = page;
// get the value of the field
var donationQuery = $.njDialerPlugin.getFieldValue("DonationQuery");
// decision based on field value
if (donationQuery == "already_help_other_charities")
nextPage = $.njDialerPlugin.getPage("Already Help");
else if (donationQuery == "not_sure_giving_cc_details")
nextPage = $.njDialerPlugin.getPage("Not Sure Giving CC");
else if (donationQuery == "how_do_you_help")
nextPage = $.njDialerPlugin.getPage("How Do You Help");
else if (donationQuery == "how_different_from_other_charities")
nextPage = $.njDialerPlugin.getPage("How Different");
else if (donationQuery == "do_you_receive_gvmnt_support")
nextPage = $.njDialerPlugin.getPage("Receive Gvmnt Support");
else
alert("Please select a customer query from one of the choices listed");
return nextPage;
};
