谷歌浏览器禁止window.close的问题

Scripts may close only the windows that were opened by it.

function closeWindow(){    
    var browserName=navigator.appName;    
    alert(browserName);    
    if (browserName=="Netscape") {    
        window.open(‘‘,‘_self‘,‘‘);    
        window.close();     
    } else {    
                window.close();    
    }  
}
