Pass array in JavaScript to another page without using sessionStorage or localStorage

Question

有谁知道如何在不使用sessionStorage或localStorage情况下将array值传递给另一个页面？

Answer 1

I take it that you have a page; you want to send some data to another page, by clicking in a button from the first page. You can do it like this:

function sendData(url, data) {
  window.location = url + "#" + JSON.stringify(data);
}


function getData() {
  if (window.location.hash == "")
    return "";
  try {
    return JSON.parse(window.location.hash.substr(1));
  } catch {
    return "";
  }
}

And you can use these two functions like this:

<button onclick="sendData("page.html", [1, 2, 3])">Redirect</button>

And you can get the data by calling getData() in the second page.

Answer 2

You can pass the array into query string .

You can put the arry into query string in a.html when you go to b.html using beforeunload event, then you get this array in b.html using DOMContentLoaded event.
