Hello
Let me try to explain the situation: I have a few dependant Lookup fields (lets say Country - Province - City - Street).
- When I select a Country first, only Cities, Streets and provinces in that country are shown (dependant lookup and provinces/streets via FetchXML)
- When I select a Province, only Cities and streets of that province are shown in the view of the City and Street lookup, Country is filled in automatically based on the province (1:N)
- When I Select a City, the Country and Province are automatically filled based on the City and the Street Lookup shows the streets in that City.
- When I Select a Street, Country, Province, City are filled in automatically.
I'll try to explain my problem even my English isn't that great: A User here needs to have the functionality to keep changing those lookup values. Now the problem is, when all Lookup fields are filled in and the user selects a Province, I want to set the
values of City and street on null (same for Country -> Province/City/Street on null // City -> Street on null). This means a User selects a Province -> OnChange province is called -> Clears City and Street -> Fills in Country automatically
(as mentioned before) -> On Change Country is fired -> Clears Province (not wanted), City,Street,...
Small Example Explained:
handleOnChangeProvinceAttribute: function () {
var province= this.getSelectedProvince();
this.updateView("City",province);
this.updateView("Street",province);
//Update Country by selected Province (1:N) -> Calls OnChange Country (= handleOnChangeCountryAttribute)
this.getAttribute("Country").setValueByProvince(province);
//I Need to empty Street and City
this.setValueAsNull(["City","Street"])
}
handleOnChangeCountryAttribute: function () {
var country= this.getSelectedCountry();
this.updateView("Province",country)
this.updateView("City",country);
this.updateView("Street",country);
//I Need to empty Street and City & PROVINCE :(
this.setValueAsNull(["City","Street","Province"])
}
I really don't know how I should handle this problem (that is why I came here). I am not a Javascript Expert either, but I need some input what the possibilities are to solve a problem like this.
