How to hide an input field from another page via javascript?

I have two page .html . In one of the pages I have two options to mark radio both have id , they are XPTO and YPTO e. What I need to do is, when choosing XPTO and then pressing the sign up button, it has to disable a field on the other page.

In my example the field is named LastName , so I was using a condition in javascript If document.getElementById("xpto").textContent is this element, on the other page the field > Surname disappears.

Is there any way to do this even though I'm going to another page next?

My codes below:

PAGE 1: test.html

<body>
    <table border="1">
        <tbody>
            <tr>
                <td><input type="radio"></td>
                <td><input type="radio"></td>
            </tr>
            <tr>
                <td id="xpto">XPTO</td>
                <td id="ypto">YPTO</td>
            </tr>
        </tbody>
    </table>        
    <br /><br />
    <button><a href="test2.html" onclick="disableSobrenome()">CADASTRAR</a></button>
</body>

PAGE 2: test2.html

<body>   


    <form>
        Nome:
        <input type="text" id="nome">
        Sobrenome:
        <input type="text" id="sobrenome">
    </form>

    <a href="test.html">VOLTAR</a>
</body>

Script.js:

function disableSobrenome() {

    if (document.getElementById("xpto").textContent)
    {
        document.getElementById("sobrenome").style.display='none';
    }
}
