Here is the most recent and updated Ajax code equivalent of the @DBColumn formula for Lotus Notes. By using this, you can select the column of your choice and return the results.
Paste the code below on the event that you'd like it to execute -- for example, onClick, onLoad, etc.
ObjCombo1=document.forms[0].combo1;
ObjCombo2=document.forms[0].combo2;
viewname = "testvik";
//dbColumn("serverName","DbName",
viewname,1,Combo1)
keyVal=ObjCombo1.options[
ObjCombo1.selectedIndex].text;
ObjCombo2.length = 0
dbLookup("http://127.0.0.1","R&D/testing.nsf",
viewname , keyVal , 2, ObjCombo2 )
