刷新浏览器后，sessionStorage消失了-Javascript [英] sessionStorage is gone when browser is refreshed - Javascript

问题描述

我试图在sessionStorage中保留一些数据，但是如果刷新页面或离开链接然后返回，则sessionStorage不再存在.

I am trying to keep some data in sessionStorage, but if I refresh the page or leave from a link then come back, the sessionStorage no longer exists.

我是sessionStorage的新手，如果很明显，对不起.

I am new to sessionStorage, so sorry if this is an obvious fix.

基本上，我将一个数组存储到sessionStorage中.

Essentially I store an array into the sessionStorage.

  $scope.addPlant = function(plant) {
    for (i = 0; i < $scope.userPlantList.length; i++) {
      if ($scope.userPlantList[i] === plant) {
        alert("You have already added this plant");
        return;
      }
    }
    $scope.userPlantList.push($scope.currentPlant);
    sessionStorage.setItem("Plants",JSON.stringify($scope.userPlantList));
  };

然后当我想查看所有存储的内容

And then when I want to see what is all stored

  $scope.retreiveList = function() {
    var retrieved = sessionStorage.getItem("Plants");
    $scope.userPlantList = JSON.parse(retrieved);
  }

当我根本不刷新页面/应用程序时，这很好用.

And this works fine when I do not refresh the page/app at all.

问题:如何在刷新/立即重新访问期间使sessionStorage持续使用?

Question: How can I get my sessionStorage to last during a refresh/immediate re-visit?

推荐答案

通过查看开发者工具检查数据是否真的消失了

Check if the data are really gone by looking at the developer tools

如果您使用的是chrome:F12->资源"标签->会话存储".

If you using chrome: F12 -> Resources tab -> Session Storage.

sessionStorage与浏览器"选项卡一起使用.每当您关闭标签页时，sessionstorage数据就会被清除.

sessionStorage lives with the browser tab. whenever you close a tab the sessionstorage data will be wiped out.

如果您希望在标签之间共享某些内容，请查找localStorage.

if you want something that will be shared across tabs, look for localStorage.
