I know in JavaScript on forms you can loop through all the objects on a page, for example to check all text boxes have some kind of value entered in them before a form is submitted. is there a way to do that same thing in servoy. what im looking to do is to be able to go through loop the objects on my form when i start up and if displayType=“COMBOBOX” then i do something to the combo box. is there a way to script that in servoy?

thanks ahead of time,

If you use a very strict naming convenction naming convention you can organize a sort of loop of form elements, just name your elements something like:  
elment\_1, element\_2, …, element\_n

and then for example you can use a loop like this for setting element visibility:

```auto
for ( var i = 1 ; i < 1000 ; i++ )
{
   var element_name = 'element_'+i
   if ( element_name )
   {
     forms.form_name[element_name].visible = false
   }
   else
   {
     break
   }
}

```

I’m going on memory so check the code carefully.  
Beware: it’s not really clever code though, naming your elements this way you loose indication of what they represent so you could find yourself in a hell of a time defining access security or calling a particular element by name.  
Having said that I don’t remember a function to get the dispaly type of a field so I don’t think you will be able to change comboboxes or the like.

I think the code referred to was posted in Servoy Magazine by David Workman back in March.

i think that code snippet from workman will work for me. wow thanks, i can manipulate that enough i think to get what i need going. I really apprechiate it the help from both of you.

thanks!

Wooppss… I didn’t notice that.

Late hours lead to errors… errors lead to rage, rage leads to hate and hate leads to the darkside!
