如何使用JavaScript从另一个页面访问元素ID？

Question

I am trying to access an element id of an HTML page from another page. 我正在尝试从另一个页面访问HTML页面的元素ID。 I have seen other solutions but none have worked so far. 我看到了其他解决方案，但到目前为止都没有奏效。

For example, if this is One.html 例如，如果这是One.html

<input id="a" type="text"></input>
<p id="demo"></p>

I am trying to access the element id 'a' from Two.html to get the value that has been inputted using ` 我正在尝试从Two.html访问元素ID'a'，以获取已使用`输入的值

var thing = document.getElementById('a').value;
document.getElementById('demo').innerHTML = "the value is" + " " + thing;

Answer 1

you can use localStorage 
for example in firstpage.html you save data with
var thing = document.getElementById('a').value;
localStorage.something = thing ; 
then in your seconpage.html you can use it by
document.getElementById("demo").innerHTML=localStorage.something;

Answer 2

sorry I don't have enough reputation to leave this as a comment but just a heads up, input tags are standalone tags. 抱歉，我没有足够的声誉来将此留为评论，但请注意，输入标签是独立标签。

Example: 
  <body>
    <input type="text" id="a" />
  </body>
