Hello, I’m 95% done building a new site. I hit a wall when trying to not show a button on a Dynamic page. I’m currently advertising some events using the courses preset, some events that have more than one time for that day, each time has a Booking Button. The events that have less times for the day I would like to hide the ‘Book Now’ buttons from the screen as these have no reference content in the Content Manager but are still linked to empty connected data fields. I have no experience with Velo, but I see this as the only option to achieve what I need. Any help would be appreciated. Thanks

All you have to do is…

let currentItem = $w("#myDataset").getCurrentItem(); console.log(currentItem);

You will get some results… like…

/*  
 *  {
 *    "_id":                "fcec780a-3e37-4b64-8a66-37c552c53f99",
 *    "_owner":             "f6c0f9c3-a62d-7e9f-g58d-943829af244d9",
 *    "_createdDate":       "2017-05-01T17:19:03.823Z",
 *    "_updatedDate":       "2017-05-01T17:19:10.477Z",
 *    "title":              "Dr. ",
 *    "name":               "B",
 *    "link-dynamic-name":  "/myCollection/B"
 *  }
 */

Than you generate your if-else-query (statement)…

if( ... ) { ... }
else { ... }

Example for —> “title” - DB-FIELD…

if(currentItem.title) {console.log("Title exists on the current selected item.");}
else {console.log("Title do not exist on the current selected item.");}

Put everything withing the onReady-part(s) of your code…

$w.onReady(()=>{ ... });

Including → “datasetOnReady()”-part…

$w("#myDataset").onReady(()=> { ... });

Which would look like…

$w.onReady(()=>{
    $w("#myDataset").onReady(()=> { ... });
});

Awesome thanks! I have another couple of questions on Events if okay? Is it possible to add a field in the event setup for an external URL that is used instead of the standard register form? There’s also a prompt on the event page that states, ‘Select Another Date’ if an event have more than one date, however, I have more than one time on the same day so this is misleading, could it be changed to read ‘Select Another Time’? I will probably reach out personally to help implement this and/or the above.
