Hide and unhide button objects

See if you can use the style.visibility (note the spelling...)

Here are two methods I use:

var objToolBarBtn = lawForm.UIDocument.getElementById("xxx");
if (objToolBarBtn) {
objToolBarBtn.style.visibility="hidden";
}

var objToolBarBtn = lawForm.UIDocument.getElementById("xxx");
if (objToolBarBtn) {
objToolBarBtn.style.visibility="visible";
}

lawForm.getFormElement("label8").style.visibility = "hidden"
lawForm.getFormElement("label8").style.visibility = "visible"

Thanks for the fast reply! This is the syntax I was trying (had a typo in my original post, oops)

lawForm.getFormElement("push31").style.visibility = "hidden"

It does hide labels and text but for a button in 9.0.1 the text/name of the button hides but the empty box of the button is still visible. I'm trying to make the button disappear entirely.

Unfortunately in 9.0 hiding buttons doesn't work anymore.  You have to either disable them instead or remove the button from the form and dynamically add/delete them in the OnInit and OnAfterTransaction functions using javascript.

Thanks Gary! Could you possibly show me an example of how you would delete/add in javascript? I will put it in OnAfterTransaction and it will be perfect! (at least I envision it will be...)

I would also like to see an example of how to dynamically add/delete buttons in DS. I'm working on a project that could use that functionality

Any update on dynamically add/delete for buttons?

The button is wrapped in a div; try:
lawForm.getFormElement("push31").parent.style.visibility = "hidden"

The parent.style.visibility solution does not work either.

I have also found a challenge hiding a listbox.  If I set visibility to hidden it hides the textbox but does not hide the icon with the drop down arrow.

Any ideas?

Try this. I was able to hide the button in 9.0 using this method:

function FORM_OnAfterFrameworkInit()
{  
      var objButton = lawForm.getFormElement("push2");
      if (objButton)
      {
        objButton.value="";
      }
}


function FORM_OnAfterTransaction(data)
{
      var objButton = lawForm.getFormElement("push2");
      if (objButton)
      {
        if( // test for show-no-show condition here )
        {
              objButton.value="ShowTheButton";
          }
          else
          {
              objButton.value="";       
          }
      }
}


The properties:
value="" will hide the entire button,
visibility="hidden" will gray-out the button, but no text shows.
