html头添加代码html
<meta http-equiv="refresh" content="3; url=http://www.baidu.com/" />
js实现缓存
1、最外层top跳转页面,适合用于iframe框架集服务器
top.window.location.href("http://www.baidu.com");
============================================================================================框架
2、window.location.href和window.location.replace的区别ui
1.window.location.href=“url”:改变url地址;url
2.window.location.replace(“url”):将地址替换成新url,该方法经过指定URL替换当前缓存在历史里(客户端)的项目,
所以当使用replace方法以后,你不能经过“前进”和“后 退”来访问已经被替换的URL,这个特色对于作一些过渡页面很是有用!spa
3、强制页面刷新 .net
1.window.location.reload():强制刷新页面,从服务器从新请求! code
============================================================================================xml
4、window.location.reload();
页面实现跳转和刷新:
1 history.go(0)
2 location.reload()
3 location=location
4 location.assign(location)
5 document.execCommand('Refresh')
6 window.navigate(location)
7 location.replace(location)
8 document.URL=location.href
这几个均可以刷新:
window.location.reload();刷新
window.location.href=window.location.href;刷新
window.close();关闭窗口,不弹出系统提示,直接关闭
window.close()至关于self属性是当前窗口
window.parent.close()是parent属性是当前窗口或框架的框架组
页面实现跳转的九种方法实例:
1 setTimeout('window.navigate("top.html");',2000); 2 setTimeout('window.document.location.href="top.html";',2000); 3 setTimeout('window.document.location="top.html";',2000); 4 setTimeout('window.location.href="top.html";',2000); 5 setTimeout('window.location="top.html";',2000); 6 setTimeout('document.location.href="top.html";',2000); 7 setTimeout('document.location="top.html";',2000); 8 setTimeout('location.href="top.html";',2000); 9 setTimeout('location.replace("top.html")',2000);
//window对象
//document对象
//location对象
//href属性
//1.window.document.location.href
//2.window.document.location
//3.window.location.href
//4.window.location
//5.document.location.href
//6.document.location
//7.location.href
//8.window.navigate
//9.location.replace
只要使用location方法,和任意的window对象,location对象,href属性连用,均可以页面的跳转
解释:
location是个对象,好比本页的document.location和window.location的属性有
location.hostname = community.csdn.net
location.href = http://community.csdn.net/Expert/topic/4033/4033372.xml?temp=2.695864E-02
location.host = community.csdn.net
location.hash =
location.port =
location.pathname = /Expert/topic/4033/4033372.xml
location.search = ?temp=2.695864E-02
location.protocol = http:
可见href是location的属性,类别是string。
