dataproviderID setting to null

[Harjo]

HI,

I have some method where I scan all the elements of a form and get the dataproviderID of an element.

Code: Select all

var vProviderID = forms[vForm].elements[vElem].getDataProviderID()

Now for example this code returns vProviderID as a string: "scopes.globals.filter_monthfilter"
How do I set this global now to null?

Try something like:

Code: Select all

   if (/^scopes\./.test(vProviderID)) {
      var split = vProviderID.split(".");
      scopes[split[1]][split[2]] = null;
   }

You probably need to do some more checks, but you get the idea.

[Harjo]

yes I did something like that already, but we still have code run in Servoy 6 and Servoy 6.1
In Servoy 6 there is 'scopes.' in front, so I wanted to make this just work on both...

But you say, that is not possible?

[Joas]

So you want the same code to work in 6.0 and 6.1? That doesn't look like a good idea to me, but it is possible if you do something like:

Code: Select all

   var split = vProviderID.split(".");
   if (/^globals\./test(vProviderID)) {
      globals[split[1]] = null;
   } else if (/^scopes\./.test(vProviderID)) {
      scopes[split[1]][split[2]] = null;
   }

No, but i thought there was maybe another way to set a (global) dataprovider independant of the name.

this should work:

Code: Select all

eval(vProviderID + '=null;')

or if you have a form

Code: Select all

vForm.controller.setDataProviderValue(vProviderID, null)

Hmmm, I'm don't think I understand correctly what you are trying to do.

vForm.controller.setDataProviderValue(vProviderID, null)

YES jBrancoIF, you are the man!

Code: Select all

vForm.controller.setDataProviderValue(vProviderID, null)

works perfectly. and despite of the name is 'scopes.globals.myglobal' (6.1.x) or 'globals.myglobal' (6.0.x)

Thanks!
