you can retrieve script path by parsing document tags and compare it with the document location.

var pathToScript=function(scriptFileName){
    // scan document to get script location
    var sclist = document.getElementsByTagName("script");
    var found = null;
    for(var i=0;i0&&_to__.length>0&&_from[0]==_to__[0]){
            _from.shift();_to__.shift();
        }
        // add parent dir offset if any
        while(_from.length>0){
            _to__.unshift("..");_from.pop();
        }
        // return relative document path to script folder
        return _to__.length>0?(_to__.join("/")+"/"):"";
    }else{
        throw("\npathToScript Error :\nscript source '"+scriptFileName+"' not found in document.");
    }
};

// use in script file "myscript.js" :
var pathToMe = pathToScript("myscript.js");
console.log("my dir : "+pathToMe);
