If else Statement in Foreach loop

Question

I added if (windows = id | ....){do nothing} but it doesn't work.

    var html;
    var windows = document.getElementsByClassName("windows");
    for (var i = 0; i < windows.length; i++) {

    var win = document.getElementById(windows[i].id);
    
    if(win.id == "windows-s" || win.id == "windows-f" || win.id == "windows-p"){
        
    }else{
        var win_el = document.getElementById(win.id).id;
        win_el.forEach(function(div){

        div.removeAttribute("style");
        var clonedDiv = div.cloneNode(true);
        var inner_HTML = clonedDiv.innerHTML;
        
        html += "HTML"+ i++ +"=" + inner_HTML + ",";
        )}
    }
    console.log(html);
    }

Code takes parent(windows) innerHtml and changes attributes with each child. After that, it creates result html1 = innerhtml, html2 = innerhtml, html3 = innerhtml etc... Everything works fine, but now I need to avoid some windows by their id. I added if (windows = id | ....){do nothing} but it doesn't work.
