Thanks this works but the next question.
How get map.layers[this digit] in function 
or how to give it as variable to function 


Му function

function func1(mnum){
        alert(mnum); //works 
            html = ""
            features = map.layers[mnum].features; //not works returns map.layers[mnum] undefind
            if (features.length == 0){html = ""}
            else  {
                html += "<p>Mid</p><div class=\"info\"><fieldset>";
                for (var f = 0; f < features.length; f++) {
                    html +="<input value=\""+features[f]+"\" type=\"checkbox\">" +features[f].attributes["datsetid"]+"</br>";
                }        
               html += "</fieldset></div>" 
            } 
            document.getElementById('select_wfsQ').innerHTML = html;
          }

wfs_e.events.on({ 'loadend': func1(3) }); // if just func1 and define mnun inside function all ok
