When i hide some fields from the Editform using javascript, what will happen to the fields that hve been hidden

Question

I am working on an EnterpriseWiki site collection, and when users edit the page properties as follow:-
then will get all the fields inside the EnterpriseWiki content type as follow:-
now i want to hide all the fields except the ; Title & Name, so i edit the EditForm and i add the following script:-
<script>
$('#formTbl tr').filter(function ()
return !$(".ms-standardheader", this).text().match(/Name|Title/i);
}).remove();
</script>
so currently when users edit the wiki page properties they can only edit the Name & Title, because the script hide the other fields.
My question is what will happen to the other values such as the page content, assign to , etc that have been hidden.. I test this and seems that when editing the name and title the other values will not get effected which is what i need, but not sure how
did SharePoint handle this, i was afraid that hiding the other columns will set their values as null or empty if the user save the editform with only the title and name inside it ? can anyone adivce on this ?

Hi John,
From your description, my understanding is that you are worried about the values of some fields
 will been saved as empty if you hide them in EditForm.
If you hide some fields in EditForm, it means that you could not edit them. These fields’ values will not be changed after editing Title field or Name field. When you click Save button, they will be still the values before changing the Title field or Name
field.

i found this very critical issue with hiding the fields from the edit form, now i wrote the following script inside the edit form , to hide all the fields except the Name
<script>
$(document).ready(function(){
$('#formTbl tr').filter(function () {
return !$(".ms-standardheader", this).text().match(/Name/i); }).hide();
$('#ctl00_ctl40_g_6c7d849e_da6b_4138_be9f_b99bde542065_ctl00_ctl02_ctl00_ctl04_c‌ ​tl00_WebPartMaintenancePageLink').hide(); });
</script>"
. and now if I submit the editform (which only contain the Name) all the html tables inside the wiki page content will be removed.
