浏览器后退,页面刷新
方法总结:
1.在jsp头增加下面代码,没有实现;
<META HTTP-EQUIV="pragma" CONTENT="no-cache"> <META HTTP-EQUIV="Cache-Control" CONTENT="no-cache, must-revalidate"> <META HTTP-EQUIV="expires" CONTENT="0">
2.用js强制刷新,可以实现刷新,但是正常访问时刷新了两次
window.onload = function(){ if(window.name!="hasLoad"){ location.reload(); window.name = "hasLoad"; }else{ window.name=""; } }
3.java代码,在jsp中增加下面java代码,可以实现刷新
response.setHeader("Pragma","no-cache"); response.setHeader("Cache-Control","no-cache");
response.setDateHeader("Expires", 0); response.setHeader("Cache-Control", "no-store");
