如何从单选按钮获取文本值并将值分配给特定div

Question

如果我使用一个文本框和3个div，如何在该div中设置输入的值？ 这是我的代码。我必须从选中的单选按钮中获取div值。同样，我如何获得文本框值？

这是我的代码。

<form id="myform">
<div>Choose option:</div>
<div>
<input type="radio" name="user_options" value="456"/>
</div>
<div name="deff" id="val1" x>123</div>
<span>CSS</span>
<br></br>
<div>
<input type="radio" name="user_options" value="456" /> 
</div>
<div name="deff" id="val2" >456</div>
<span>html</span>
<br></br>
<div>
<input type="radio" name="user_options" value="678" /> 
</div>
<div name="deff" id="val3" >678</div>
<span>jquery</span>
<br></br>

<div name="deff" id="val4" >
    <input type="radio" name="user_options" value="675" />
</div>
    <input class="text-input" id="other-input" size="5" value="">
<span>JS</span>
<br></br>


<div><button id="radio_submit" type="button">Show Selected Radio</button></div>
</form>
<div id="valueee"></div>


<script>
    $(document).ready(function() {
        $("#radio_submit").click(function (e) {
         var check = $("input[name=user_options]:checked").parent().next().text();
         if(!check){
              alert('Please select options!');
         }else{
              $('#valueee').html(check);  
         }
        });
    });
</script>

不确定您的意思，但可能需要再次检查并尝试 val() ，如果 undefined ，

$(document).ready(function () {
    $("#radio_submit").click(function (e) {
        var check = $("input[name=user_options]:checked").parent().next().text();
        if (!check) var check = $("input[name=user_options]:checked").parent().next().val();
        if (!check) {
            alert('Please select options!');
        } else {
            $('#valueee').html(check);
        }
    });
});

您可以使用is()检查下一个元素是div还是input。如果input然后使用.val()读取值，则使用.text()。

$(document).ready(function() {
    $("#radio_submit").click(function (e) {
     var next = $("input[name=user_options]:checked").parent().next();
     //check if next element is input and read value otherwise read text         
     var check = '';
     if($(next).is('input'))
         check = $(next).val();
     else
         check = $(next).text();

     if(!check){
          alert('Please select options!');
     }else{
          $('#valueee').html(check);  
     }
    });
});
