Solved: ODS HTML HeadText gets truncated

RichardDeVen · Posted 09-02-2021 01:01 PM

The following code produces HTML wherein the specified headtext gets truncated to 256 characters.

Q: Does any know how to increase the allowed headtext or otherwise inject such?

SAS program specifying a head text of 320 characters

options lrecl=32000;  * does nothing for me regarding headtext! ;

ods html 
  path='.'
  file = 'sample.html'
  style=plateau
  headtext=
'<!--5678901234567890123456789012345678901234567890123456789012345678901234567890
12345678901234567890123456789012345678901234567890123456789012345678901234567890

;

proc print data=sashelp.class;
run;

ods html close;

From the documentation for ODS HTML ( I added some emphasis). I don't know if that a general HTML limit or SAS ODS limit.

HEADTEXT= 'markup-document-head'

specifies markup tags to place between the < HEAD> and < /HEAD> tags in all of the output files.

markup-document-head

specifies the markup tags to place between the < HEAD> and < /HEAD> tags.

Restriction	HEADTEXT= cannot exceed 256 characters.
Requirement	You must enclose markup-document-head in quotation marks.

Tips	ODS cannot parse the markup that you supply. It should be well-formed markup that is correct in the context of the <HEAD> and </HEAD> tags.
	Use the HEADTEXT= option to define programs (such as JavaScript) that you can use later in the file.

The > 256 character was for including a number of external javascript libraries.

I was able to get around the issue by placing some of the <script> tags at the bottom of the html

Example:

filename htmlout "great-page.html";

ods html body=htmlout (NO_BOTTOM_MATTER) style=plateau
  headtext='<link rel="stylesheet" href="https://cdn.datatables.net/1.11.0/css/jquery.dataTables.min.css">'
;

* tagattr is IMPORTANT;
proc print data=sashelp.class  style(table)=[tagattr='id="MyTable1"'];
run;

ods html close;

* stuff that would not fit in html HEADTEXT limit of 256 characters;
data _null_;
  file htmlout MOD;
  put
    '<script src="https://code.jquery.com/jquery-3.6.0.min.js" integrity="sha256-/xUj+3OJU5yExlq6GSYGSHk7tPXikynS7ogEvDej/m4=" crossorigin="anonymous"></script>'
  / '<script src="https://cdn.datatables.net/1.11.0/js/jquery.dataTables.min.js"></script>'
  / '<script>'
  / '$(document).ready(function(){'
  / '  debugger;'
  / '  $("#MyTable1").DataTable({paging: false});'
  / '})'
  / '</script>'
  ;
  put
    '</body>'
  ;
run;
