Question

我在页面上有这些单选按钮，按钮可以转到下一页。（被称为'Doorgaan'）。在下一页中，我有一个id为“CatNaam”的h2，我希望将值[CATEGORIENAAM]更改为选中的单选按钮的值。我该怎么做？

    <div data-role="page" id="beoordelen" data-theme="a">

        <div data-role="header">
            <h1>Beoordelen</h1>
            <a class="ui-btn-left" data-theme="a" data-rel="back">Vorige</a>
        </div><!-- /header -->

        <div data-role="content" data-theme="a">    
            <h2>Kies categorie</h2>
            <form id="oordeelKeuze" method="get">
                   <p>      
                      <input type = "radio" name = "categorie-oordeel" id = "goedkoop-bier" value = "Goedkoop bier" checked = "checked" />
                      <label for = "goedkoop-bier">Goedkoop bier</label>
                   </p><p>                    
                      <input type = "radio" name = "categorie-oordeel" id = "muziek" value = "Muziek" />
                      <label for = "muziek">Muziek</label>
                    </p><p>      
                      <input type = "radio" name = "categorie-oordeel" id = "gezelligheid" value = "Gezelligheid" />
                      <label for = "gezelligheid">Gezelligheid</label>
                    </p>   
            </form>
            <p><a href="#beoordelen2" data-direction="reverse" data-role="button" data-theme="b">Doorgaan</a></p>   

        </div><!-- /content -->


    </div><!-- /beoordelen -->

    <!-- Start of fifth page: #beoordelen2 -->
    <div data-role="page" id="beoordelen2" data-theme="a">

        <div data-role="header">
            <h1>Beoordelen</h1>
            <a class="ui-btn-left" data-theme="a" data-rel="back">Vorige</a>
        </div><!-- /header -->

        <div data-role="content" data-theme="a">    
            <h2>Geef cijfer voor</h2>
            <h2 id="CatNaam">[CATEGORIENAAM]</h2>
</div>
</div>

Answer 1

使用Jquery ..

给你按钮（Doorgaan）一个id ..

 <p><a href="#beoordelen2" data-direction="reverse" data-role="button" data-theme="b" id="buttonID">Doorgaan</a></p>   //buttonID in this case

并在您的按钮（Doorgaan）上点击添加此...

$('#buttonID').click(function(){
   var selectedRadio= $("input[type='radio'][name='categorie-oordeel']:checked").val();
  $('#CatNaam').text(selectedRadio);
})

Answer 2

如果你使用jQuery，你可以这样做：

var val = $('input[name="categorie-oordeel"]:checked').val();
$('#CatNaam').text(val);

将值更改为选中的单选按钮的值
