how do you show/ hide a formatter on form

beycos · ‎06-02-2026

Hello everyone,

I have created a new formatter and this is the UI macro for this Formatter.

<j:jelly xmlns:j="jelly:core">

<button id="refreshBtn"

class="btn btn-default"

style="background-color:#007bff; color:white; border-color:#007bff;margin-right:200px;"

onclick="refre**bleep**emList()">

Refresh Item List

</button>

</div>

function refre**bleep**emList() {

g_form.save();

}

</script>

</j:jelly>

On the form I have choice field called "Type" .

My aim is this formatter should be hidden when type is null and should be visible when Type is not null.

I have created client script

function onChange(control, oldValue, newValue) {
setTimeout(function() {
var wrapper = document.getElementById('refreshWrapper');
if (!wrapper) return;

wrapper.style.display = newValue ? 'flex' : 'none';
}, 300);
}

However this does not seem to be working. Do you any recommendations or ideas about what might be wrong ? Any help would be appreciated.

Best Regards,

Beyza
