I have some jquery code that is quite old that uses "removeOption(/./).addOption(cats_reg, false)" to change the select options based on a checkbox. The version of jquery is jquery-1.3.2.js.  

I have to move my code to where jquery 1.10.2 is being used. The code removeOption(/./).addOption(cats_reg, false) is no longer functions in the new jquery. 

2. $("#offcampus_ws_box").click(function(){
3. $(".offcampws").toggle();
4. $(".chngtxt").toggle();
5. if (cats_reg !== undefined) {
6. if (!($("[name=jobs_workstudy]").attr("checked"))) {
7. $("[name=jobs_categories_name]").removeOption(/./).addOption(cats_reg, false);
8. if (!wasWorkstudy){
9. document.form.jobs_categories_name.selectedIndex=selected;
10. }
11. } else {
12. $("[name=jobs_categories_name]").removeOption(/./).addOption(cats_ws, false);
13. $("#benefits_text").html("<strong>Educational Benefits:</strong>");
14. if (wasWorkstudy){
15. document.form.jobs_categories_name.selectedIndex=selected;
16. }
17. }
18. }
19. });

If it helps, cats_reg and cats_ws select option items are created as follows in php:

2. $cats_reg = "SELECT categories_name FROM ...";
3. $r = pg_query($conn, $cats_reg) or die(pg_last_error());
4. echo "var cats_reg = {\n";
5. 
   
6. $num = pg_num_rows($r);
7. for ($i=0; $i<$num; $i++) {
8. $d = pg_fetch_row($r,$i);
9. 
   
10. echo "\"$d[0]\"" . " : " . "\"$d[0]\"";
11. if ($i<($num-1)){
12. echo",\n";
13. }else{
14. echo"\n";
15. }
16. }
17. echo "};\n";
18. 
    
19. 
    
20. $cats_ws = "SELECT categories_name FROM ...";
21. $r = pg_query($conn, $cats_ws) or die(pg_last_error());
22. echo "var cats_ws = {\n";
23. $num = pg_num_rows($r);
24. for ($i=0; $i<$num; $i++) {
25. $d = pg_fetch_row($r,$i);
26. 
    
27. echo "\"$d[0]\"" . " : " . "\"$d[0]\"";
28. if ($i<($num-1)){
29. echo",\n";
30. }else{
31. echo"\n";
32. }
33. }
34. echo "};\n";
35. }
