how to tell if a global is allready defined


    Feb 08 2006 | 3:05 am
    if i have a js file which creates a global and some global js variables, how can i prevent another instance of that js overwriting/interfering with that global. Is there an "isdefined()" or similar method.
    thanks,

      Oliver, heres a little fragment. I had a hard time dealing with this issue. and I'm still not quite sure what works and what doesn't. it's an anomaly just seems to obvious to me. I mean who want to define a global that you cant read elsewhere.... anyway this seems to do the trick. its from my solomute.js
      var gtabs = new Global("sologlobal"); if(gtabs[mygroup]==undefined) {gtabs[mygroup]=new Object();}
      someone more knowledgeable will probably say something more interesting
