The code parts that you should change on your side

To get this code working properly on your side, you should do the following:

• Change the ‘Serial Number’ lookup field with the corresponding lookup field name in your list.

var LookupField= $("select[title='Serial Number']");

• Again, replace the lookup field name with your own, to get the selected lookup value.

var LookupField = $("select[title='Serial Number'] option:selected").text();

• Change the ‘Lookup List’ name with your own, it’s the second list, not the main list name.

var LookupList = clientContext.get_web().get_lists().getByTitle('Lookup List');

• Don’t forget to set the corresponding internal lookup field name in CAML Query specifically at “<fieldRef />” tag.

'<View><Query><Where><Eq> <FieldRef Name=\'Serial_x0020_Numaber\' /> <Value Type=\'Text\'>' + LookupField + '</Value></Eq></Where></Query><RowLimit>1</RowLimit></View>'

• In function “Succeed”, specifically in the below code, you should change
  • The “Name” with the display field name in the new form in the Main List,
  • The “Title” with the internal field name in the second Lookup List.

$("input[title='Name']").val(item.get_item('Title'));

Note: the field name that set in this line “Item.get_item(“Title”)” is the Internal Field Name, it’s not the displayed name, so if you have field Called for example “M Qassas” it should be “M_x0020_Qassas“
