"undefined" string

[terp]

On my record producer, the string "undefined" appears upon opening the form. It is not defined as a default value, the "type" is a multi line text and is mapped to the field on the table.   Can anyone   suggest why this string is there and how get rid of it?

Does the variable have a default value defined? If so, what is it? If not, do you have a client script populating the default value?

Hi Eric,

Just make sure that whenever your're assigning a value to this field you first validate that the variable is valid and does contain a value on it.

For instance, something like the following:

function onLoad() {

     var incredible;
     if (incredible && incredible != ''){
       g_form.setValue('myVariable', incredible);
     }
}

if i miss adding the first validation to check if the variable is initialized, then I will get the undefined value on the field:

function onLoad() 
     var incredible;
     if (incredible != ''){
       g_form.setValue('myVariable', incredible); // myVariable will be set to Undefined since the variable incredible was never initialized
     }
}

I hope this helps!

Thanks,

Berny

Thanks for the suggestions and pointing me one direction.   I checked the default values on the record producer and table,   nothing listed there.   Also checked the client scripts.   There is only 1 client script with that field name listed and that is pulling values from another table on the condition of a UI action.

In this case, I am opening the record producer form, and the form should be blank (including this field) and "undefined" is in the field. If this makes a difference, in the table, the field is a string with a size limit of 500 and in it is mapped in the record producer as a multiple line text.   When the record producer form is opened this field should be empty.

This was the only client script that I have with the field.   Any additional thoughts would be appreciated and Happy New Years to everyone.

function onChange() {

                            //control, oldValue, newValue, isLoading    

                            var inventory = g_form.getReference('u_inventory_search');

var shipping_special_instructions = inventory.u_shipping_special_instructions;

g_form.setValue('u_shipping_special_instructions',shipping_special_instructions);

Hi Eric,

Try the following...

if (shipping_special_instructions && shipping_special_instructions != ''){
         g_form.setValue('u_shipping_special_instructions',shipping_special_instructions);
}

Thanks,
