MemberI use a smart-combo-box.
Here mi code within a <form> </form> tag.
<smart-combo-box selectionMode=”zeroOrOne” class=”elemento_combobox_valore” name=”e681760908″ selected-indexes=”[1]” filterable=”” optional=”true” type=”combo” desc=”ProdottoFERRETTI” onchange=”mostraAlertMsgOption(this); eseguiRefresh(this);” onfocus=”on_focus(this)”>LAN<smart-list-item style=”background-color: transparent;” alert_msg=”” value=”**”>
</smart-list-item>
<smart-list-item style=”background-color: transparent;” alert_msg=”” value=”LAN”>Lang</smart-list-item>
</smart-combo-box>
When I get back my data I get “Lang” and not LAN.
What’s wrong?
Tks

MemberHi Tullio,
Thank you for contacting us!
In your case I would recommend you to use thedataSource
property of the component and then set thevalue-member
to the value and also thedisplay-member
to the value that will be displayed like in the following code snippet:<smart-combo-box id = 'combobox' selectionMode="zeroOrOne" class="elemento_combobox_valore" name="e681760908" value-member='value' display-member = 'label' filterable="" optional="true" type="combo" selected-indexes='[0]' desc="ProdottoFERRETTI" onchange="mostraAlertMsgOption(this); " onfocus="on_focus(this)" placeHolder = "LAN" > </smart-combo-box> <script> window.onload = function (){ let comboboxMemberValue = document.getElementById('combobox') comboboxMemberValue.dataSource = [{ label: "Andrew", value: 1222, group: "Product Owners" }, { label: "Natalia", value: 2222, group: "Developers" }]; comboboxMemberValue.addEventListener('change', ()=>{ alert( comboboxMemberValue.selectedValues) }) } </script>
Or if that doesn’t suits you we have made another code snippet for you which showcases you how to achieve the functionality you aim to
<smart-combo-box selectionMode="zeroOrOne" class="elemento_combobox_valore" name="e681760908" value-member='value' filterable="" optional="true" type="combo" selected-indexes='[0]' desc="ProdottoFERRETTI" onchange="mostraAlertMsgOption(this); " onfocus="on_focus(this)" placeHolder = " LAN"> <smart-list-item style="background-color: transparent;" alert_msg="" value="111111113">1231</smart-list-item> <smart-list-item style="background-color: transparent;" alert_msg="" value="LAN1223">Lang</smart-list-item> </smart-combo-box> <script> function on_focus() { } function mostraAlertMsgOption(){ const combobox = document.querySelector('smart-combo-box'); console.log( combobox.selectedValues) }; function reloadFunction (){ window.location.reload(); }
Let me know if that works for you!
Please, do not hesitate to contact us if you have any additional questions.
