Hiding a button control

I need to hide a button if certain things apply. Here is the code I came up with:
var ctrlGID = Runner.getControl(pageid, 'GroupID');

var ctrlBtn = Runner.getControl(pageid, 'PLACED');
ctrlGID.on('change', function(e){

if (this.getValue() == 'Recruiters'){

ctrlBtn.hide();

}else{

if (this.getValue() == 'Employers'){

ctrlBtn.hide();

}}

});
Now, I am not sure what the button control syntax is (that is the PLACED above). In this case, if the GroupID is either 'Recruiters' or 'Employers', I want the button marked PLACED to hide.
Any help is appreciated.

Javascript API can be only applied to core PHPRunner form controls like text fields, dropdown boxes etc.'
To show hide a button you need to use pure Javascript.

Check this article for example:

document.getElementById('x').style.visibility='hidden'; // hide

document.getElementById('x').style.visibility='visible'; // show
Sounds logical. My only two questions are:
(1) where the line states, getElementById('x')
'x' is the button, but how do I find out the elementID of it?
(2) where do I place this code in the form? What event area does it go?

Mike,
you need to add ID for your button manually (id=customvalue) and then use getElementById('customvalue') to access this button.

Place your code in the JavaScript onload event on the Events tab.
