JavaScript not working on display form

I have some code that doesn't work with the display form but works with edit and new. The form has spaces to enter information but if no information is entered, the form should show the spaces. Here is my code and form below. Can someone tell me why it's not working?

fd.spRendered(function() {

$(".FieldTable tr:gt(1)").each(function(){
if($(this).children('td').first().find("input").val() == "")
$(this).hide();
})

Dear @ryankohn,

There are no “input” tags on the display form, that’s why it doesn’t work.

Do you know what I am supposed to use? “text”? I’ve tried that and that doesn’t work either.
