浏览器后退不刷新页面
首先，先在js文件中加入token，作为唯一标识，我自己成为时间戳，单独写一个function在js文件中，因为作为总的文件，可能在loadIFrame中加入很多功能代码
function loadIFrame(url){
token = new Date().getTime();
if(url.indexOf("?")==-1){
url+="?token="+token;
}else{
url+="&token="+token;
}
}
然后当在页面中调用loadIFrame的时候，时间戳就会自动引入在url中了，为了当浏览器点击后退时，不对之前的页面进行刷新。
<li class="oa_todoLi oaList_li" onclick="salaryDetail('+rows[i].month+','+rows[i].year+')"> //rows[i]是我页面的参数，需要传给后台
然后在页面中吧当前页面的数据整体div，存放到sessionstorage中
function salaryDetail(month,year){
var tokenDiv = $("#tokenDiv").html();
sessionStorage.setItem("tokenDiv",tokenDiv);
sessionStorage.setItem("start",start);
sessionStorage.setItem("startDate",startDate);
sessionStorage.setItem("endDate",endDate);
parent.loadIFrame("${ctx}/mobileweb/salary/currentIndex2?month="+month+"&year="+year);
}
当页面刚进行加载的时候，就对时间戳进行判断，是不是和下一次点击的时间戳一致，不一致，则进行引入sessionstorage中的内容即可，不进行刷新操作
var token = ${param.token};
var endDate = "";
var start=0;
$(function(){
//用于存放sessionstorage离线缓存里的内容，不进行再次查询
if(token==parent.token){
parent.loadData("${ctx }/salary/queryListGerenForPage");
}else{
var tokenDiv = sessionStorage.getItem("tokenDiv");
start = sessionStorage.getItem("start");
startDate = sessionStorage.getItem("startDate");
endDate = sessionStorage.getItem("endDate");
$("#tokenDiv").html(tokenDiv);
}
}
这样，就对页面完成了浏览器后退不刷新页面的功能，全部代码如下：
