Detecting blank text field for collapse in repeater

I’m one of the many trying to conditionally collapse elements in a repeater on a dynamic page. For some unknown reason, I can’t get my function to trigger on the empty text field.

My text field is within a container box and if the text element is empty, I would like to collapse both the text and the container box. Note that the code does seems to execute if I try to compare non-blank values to something loaded in the database field (such as comparing “dog” to the same loaded in the database, but I don’t seem to have success detecting an empty field???

Have read the various attempts on this subject and have lifted and tried many variations - here is what I have tried in terms of the comparison

=== undefined
=== “”
=== ‘’

Also tried the if (!itemData.description)

Here’s my code with just one of the variations I’ve tried:

export function repeater1_itemReady($w, itemData, index) {

$w( “#repeater1” ).onItemReady(() =>{
if (itemData.description === undefined) {
$w( “#text85” ).collapse();
$w( “#box5” ).collapse();
}
});
//Add your code for this event here:
}

Would greatly appreciate it if someone could take a look and explain what I must be missing or why I would see different behavior when I define a string as a non-blank.

Try this:

if (!itemData.description) {

I have tried that (see above) but I’ll give it another try …

This time it worked! Unbelievable - guess I just needed to post here. Thank you!

Great, but looking at it again, I do not see how: you magically mixed up the stub function from the property panel

exportfunction repeater1_itemReady($w, itemData, index) {

with the event itself

$w("#repeater1").onItemReady(() =>{

Looks like you have tried many things. Can´t even explain why it works, but if it does, good on you.

Yes, I had more standard code before but have had no luck for quite a while and couldn’t get it to work.

For now I’m going to let that sleeping dog lie.

One more question if you please, I need to do the same sort comparison on another field, but this one through a reference database accessed through the same repeater. What would be the proper syntax? My reference db field is newTitle1 and I am trying to assess whether a field in that database is blank as well.

This clearly doesn’t work …

if (!itemData.newTitle1.videoLabel) {
$w( “#button6” ).collapse();
