用于无线输入的localStorage？

Question

我使用以下代码在页面刷新时记住表单输入。我不完全确定如何记住单选按钮的输入。如何调整代码来做到这一点呢？

<input type="radio" name="options[Substrate]" id="clear" class="substrate" value="Clear – 125 µm SU320" />
<input type="radio" name="options[Substrate]" id="white-50" class="substrate" value="White – 50 µm Melinex 339"/>


$(document).ready(function() {

// Save Order on Refresh
    $(window).unload(saveSettings);
    loadSettings();

});


function loadSettings() {
    $('#circuitsNum').val(localStorage.setcircuit);
    $('#distanceNum').val(localStorage.setdistance);
    $('#note').val(localStorage.setnote);
    $("#metreSelect").val(localStorage.setmetre);
}

function saveSettings() {
    localStorage.setcircuit = $('#circuitsNum').val();
    localStorage.setdistance = $('#distanceNum').val();
    localStorage.setnote = $('#note').val();
    localStorage.setmetre = $("#metreSelect").val();
}
