How To Hide SharePoint People Picker Control from SharePoint List Forms

I found some difficulties in hiding SharePoint People Picker control indexed wise.
Suppose I want to hide only 2nd and 3rd people picker control from SharePoint New and Edit List Form.
here is the solution.

$(document).ready(function() {
var Attendees = GetIDOfPeoplePicker(2);
var Attendee = GetIDOfPeoplePicker(3);
$("#"+Attendees+"").closest('Div').closest('span').closest('td').closest('tr').hide();
$("#"+Attendee+"").closest('Div').closest('span').closest('td').closest('tr').hide();
});


function GetIDOfPeoplePicker(iIndex)
{
var sID = "";
var iFound = 0;
var docTags = document.getElementsByTagName("textarea");

for (var i=0; i < docTags.length; i++)
{
if (docTags[i].title == "People Picker")
{
iFound ++;

if (iFound == iIndex)
{
sID = docTags[i].previousSibling.id;
break;
}
}
}

return sID;
}

Update for SharePoint 2013 Client Picker Control:
To disable the input Filed of Client Picker
$("input.sp-peoplepicker-editorInput[id*='<ID part of ClientPicker Contrl>']").prop('disabled', true);

To hide the input Filed of Client Picker
            $("a[id*='<ID part of ClientPicker Contrl>']").hide();
