完成了applet之後就要開始寫JavaScript部分了。因為JavaScript也被瀏覽器解釋,所以可以方便地與applet進行互動。

        window.document.testApplet.setSocketURL(ip);
        window.document.testApplet.setMayRun(true);
        setTimeout("loopProcessApplet()", 1000);
    }
}


function loopProcessApplet()
...{
    processApplet();
    setTimeout("loopProcessApplet()", 1000);
}


function processApplet()  
...{
    if(window.document.testApplet == null)
        return;
    var str = window.document.testApplet.getURLName();
    if(str != "") ...{

        win.close();

function accessAppletDual()
...{
    var ip = window.location.href;
    if(window.document.testApplet != null) ...{
        window.document.testApplet.setSocketURL(ip);
        window.document.testApplet.setMayRun(true);
    }
    if(window.document.testApplet2 != null) ...{
        window.document.testApplet2.setSocketURL(ip);
        
        if(window.document.testApplet == null)
            window.document.testApplet2.setMayRun(true);
    }
    if(window.document.testApplet == null && window.document.testApplet2 == null)
        return;
    setTimeout("loopProcessAppletDual()", 1000);
}

function loopProcessAppletDual()
...{
    processAppletDual();     
    setTimeout("loopProcessAppletDual()", 1000);
}

function processAppletDual()
...{
    if(window.document.testApplet != null) ...{
        var str = window.document.testApplet.getURLName();
        if(str != "") ...{    
            window.document.testApplet.clearURLName();
            var win = window.open(str ,"","height=300,top=100,left=100,toolbar=no,menubar=no,status=no");
            win.close();
        }
    }
    if(window.document.testApplet2 != null) ...{
        if(!window.document.testApplet2.GetIsOver()) ...{    
            if(window.document.testApplet == null)
                window.document.testApplet2.setMayRun(true);
            else
                window.document.testApplet2.setMayRun(window.document.testApplet.GetIsOver());
        }
        var str = window.document.testApplet2.getURLName();
        if(str != "") ...{    
            window.document.testApplet2.clearURLName();
            var win = window.open(str ,"","height=300,top=100,left=100,toolbar=no,menubar=no,status=no");
            win.close();
        }
    }
}

         以上程式碼封裝括兩個部分,accessApplet() 、loopProcessApplet()和processApplet()用於在一個Web中控制一個applet。而後面含有Dual的則是一個頁面中含有兩個這樣的applet需要由JavaScript進行控制。
