getReference not working for Onchange client script.

[Community Alums]

Can anyone help me why getReference not working as expected for Onchange Client script. Below a sample example.

function onChange(control, oldValue, newValue, isLoading, isTemplate) {
if (isLoading || newValue === '') {
return;
}

var ci= g_form.getReference('cmdb_ci', doAlert);

}
function doAlert(ci) { 
alert("CI is:"+ci.getDisplayValue());
}

var ci= g_form.getReference('cmdb_ci', doAlert);

} //This doesnt seem like it has an opening bracket? - is this necessary at all?

Hi dola

You can use g_form.getDisplayBox('cmdb_ci').value; to get the displayvalue.

function onChange(control, oldValue, newValue, isLoading, isTemplate) {
if (isLoading || newValue === '') {
return;
}

var ci= g_form.getDisplayBox('cmdb_ci').value;

}

Thanks for your response. But can you tell what's issue with getReference.

getDisplayValue() will not work in client script.

and if you want to use getReference to get the display value then try below code

function onChange(control, oldValue, newValue, isLoading, isTemplate) {
if (isLoading || newValue === '') {
return;
}

var ci= g_form.getReference('cmdb_ci', doAlert);

}
function doAlert(ci) { 
alert("CI is:"+ci.name));
}
