Enable the Browser’s Back Button

nuBuilder's default behaviour

The browser’s back button doesn’t take one to the previous screen.

Expected behaviour

Hitting the browser’s back button takes one back to the previous website page / nuBuilder Breadcrumb.

This will make the browser’s back button work. It will detect if the back button is clicked and take you back to the previous Breadcrumb.

function gotoPreviousBreadcrumb() {
    
    // If a popup is open, close it
    if (parent.$('#nuModal').length > 0) {
        nuClosePopup();
        return;
    }
 
    var l = window.nuFORM.breadcrumbs.length;
    if (l > 1) {
        nuGetBreadcrumb(l - 2);
    }
}
 
function enableBrowserBackButton() {
    window.history.pushState({page: 1}, "", "");
    window.onpopstate = function(event) {
      if(event){
         gotoPreviousBreadcrumb();
      }
      else{
        // do nothing
      }
    }
}
 
function nuOnLoad() {
  enableBrowserBackButton();
}
