Javascript error help

Posted on by VANTAGE 90

I am not well versed in Javascript but I am trying to hide/show two different drop down (Choise) fields based on the value of another Choice field. Since I can't use Business Rule on a multi choice field I am stuck with Javascript.

Error message: Cannot read properties of null (reading 'setVisible')

My code

________________________________________________________________________________________________________

function HideFields(executionContext)
{
var formContext = executionContext.getFormContext();

var typeOfServiceProviderValue = formContext.getAttribute("vantage_typeofserviceprovider").getValue();

if (typeOfServiceProviderValue == 218700000)
{
formContext.getControl("vantage_typeofsupportiveservicesneeded").setVisible(true);
}
else
{
formContext.getControl("vantage_typeofsupportiveservicesneeded").setVisible(false);
}

var businesstype = formContext.getAttribute("businesstypecode").getValue();

if (businesstype == 809600001) //Service Provider
{
formContext.getControl("vantage_CountiesServed").setVisible(true);
}
else
{
formContext.getControl("vantage_CountiesServed").setVisible(false);
}

}

    Hi VANTAGE,

    It seems that you are passing a schema name of the field. You just need to pass the logical name instead of schema name.

    Your code should be,

    if (businesstype == 809600001) //Service Provider

    {

    formContext.getControl("vantage_countiesserved").setVisible(true);

    }

    else

    {

    formContext.getControl("vantage_countiesserved").setVisible(false);

    }

    Thanks!

    You faced the following error because a wrong logical name was passed for the field (vantage_CountiesServed). Please try again by passing the correct logical name to the setVisible() method.

    Hope this helps.

    Thanks!

    the error is with this

    vantage_CountiesServed

    you need to write the logical name so is lower case

    vantage_countiesserved
