pls, what is wrong on this code? I want, when value in fieldname “termin” is empty then “Text42” show … else when there is something value in “termin”, it remains hidden
$w.onReady( function () {
$w(“#repeater1”).onItemReady( ($w, itemData, index) => {
let items = $w(“#dataset1”).getCurrentItem().termin;
if (items === “”) {
$w(“#text42”).show();
} else {
$w(“#text42”).hide();
}
});
something this, but still doesnt work…
$w(“#repeater1”).onItemReady( ($w, itemData, index) => {
let items = $w(“#dataset1”).getCurrentItem().termin;
if (items === valueOf( null )) {
$w(“#line2”).hide();
} else {
$w(“#line2”).show();
}
});
also does not work … I do not know where I’m making a mistake …
$w(“#repeater1”).onItemReady( ($w, itemData, index) => {
$w(“#dataset1”).onReady( () => {
let item = $w(“#dataset1”).getCurrentItem();
if (item.termin) {
$w(“#line2”).hide();
} else {
$w(“#line2”).show();
}
} );
} );
The code it self looks OK, you can check:
share your site I can give it additional look…
Hi Man, (I think that I found what you try to do 
Explanation: Dataset is the collection data. The current item not change on each container in the repeater. So in your case in onItemReady you can use the itemData in order to get your current container entity.
So change your code to the following and its should work:
$w(“#repeater1”).onItemReady( ($w, itemData, index) => {
if (itemData.termin === “”) {
$w(“#text46”).show();
} else {
$w(“#text46”).hide();
}
});

hi, its work !!! Thanks a lot man !!!
hi sorry, i think i got the same problem? what should i tweak?
let fullText; // variable to hold the full text
let shortText; // variable to hold the short version of the text
$w(" #dataset1 ").onReady( function () {
// how many characters to include in the shortened version
const shortTextLength = 500;
// set the fullText variable to be the text from the collection
fullText = $w(’ #dataset1 ‘).getCurrentItem().description;
// if no text to display, collapse the text element and the button
if (!fullText) {
$w(’ #gamedescription ‘).collapse();
} else {
// if the text has fewer or the same number of characters as shortTextLength characters, display it as is and collapse the “Show More” button
if (fullText.length <= shortTextLength) {
$w(’ #gamedescription ‘).text = fullText;
} else {
// create the shortened version of the text and display it in the text element
shortText = fullText.substr(0, shortTextLength) + “…”;
$w(’ #gamedescription ').text = shortText;
}
}
});
Yours isn’t the same problem as the original forum post, they were using repeaters, whereas it seems you are just using the code for the show more button and working with Dynamic Text.
Have you read this tutorial about it here , as you seem to be missing everything for the button itself.
getting crazy what I do have wrong in this full code, I am trying to apply to my dynamic page
