谷歌浏览器禁止window.close的问题

当一个窗口不是通过window.open或者window.showModalDialog打开的时候，调用JS的window.close()

谷歌浏览器会提示如下警告，并拒绝执行

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

解决方法：

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