Symptoms

When using g_form.setValue() to change the value for a Currency field and error message is thrown in the browser console with the following message:

"TypeError: value.indexOf is not a function"

Cause

Documentation for the GlideForm API states the setValue() function takes two string parameters, the field name and the value being assigned:

setValue(string field_name, string value)

It is most likely the case that the 'value' being passed to the setValue function is not a string.

Make sure the value you are trying to set as the value is converted to a string type before passing it to the setValue() function.

Ex: g_form.setValue('field_name', parseFloat(5.34).toString());

Ex: g_form.setValue('field_name', String(5.34));
