如何在localstorage.setItem（）;中存储数据 我们可以在项目中的任何地方访问

Question

Here I want to store obj.email in localStorage.setItem("PMUsername", obj.email); that I can access in my project anywhere. But I'm not able store the value, it's coming through as null .

window.plugins.googleplus.login({}, function(obj) {
  console.log("Objct", obj);
  //$("#logs").append("<p class='success'><b>response: </b>" +localStorage.setItem("value", JSON.stringify(obj)) + "</p>")
  localStorage.setItem("value", JSON.stringify(obj));

  window.location.href = "login.html";

  document.querySelector("#image").src = obj.imageUrl;
  document.querySelector("#image").style.visibility = 'visible';

  // in below code am displaying email and username value in #feedback i.e <p id="feedback"></p>
  document.querySelector("#feedback").innerHTML = "Hi, " + obj.displayName + ", " + obj.email;
  localStorage.setItem("PMUsername", obj.email);
}, function(msg) {
  $("#logs").append("<p class='error'><b>response: </b>" + msg + "</p>");
});
}

I just need to store that #feedback value in localstorage.getitem() , so that I can access anywhere. Thanks

Answer 1

You cannot set undefined value to the localStorage .

You need to set a string to the localStorage as a value.

For this, your obj should contain property email .

Documentation on localStorage can be helpful.

Answer 2

如果没有收到电子邮件，则无法在localstorage中设置undefined。确保控制台中包含电子邮件（console.log（“ Objct”，obj））
