如果您希望它是真正动态的，并选择与输入数据相对应的无线电，那么这是可行的。它使用传入数据的性别值或使用默认值。

if(data['gender'] == ''){
 $('input:radio[name="gender"][value="Male"]').prop('checked', true);
}else{
  $('input:radio[name="gender"][value="' + data['gender'] +'"]').prop('checked', true);
};

下面是使用上述方法的示例:

<div class="ui-field-contain">
<fieldset data-role="controlgroup" data-type="horizontal">    <legend>Choose a pet:</legend>
    <input type="radio" name="radio-choice-2" id="radio-choice-1" value="choice1">
    <label for="radio-choice-1">Cat</label>

    <input type="radio" name="radio-choice-2" id="radio-choice-2" value="choice2">
    <label for="radio-choice-2">Dog</label>

    <input type="radio" name="radio-choice-2" id="radio-choice-3" value="choice3">
    <label for="radio-choice-3">Hamster</label>

    <input type="radio" name="radio-choice-2" id="radio-choice-4" value="choice4">
    <label for="radio-choice-4">Lizard</label>
  </fieldset>
</div>

在javascript中:

$("[name = 'radio-choice-2'][value='choice3']").prop('checked', true).checkboxradio('refresh');

原生JS解决方案:

 document.querySelector('input[name=gender][value=Female]').checked = true;

HTML:

<input type='radio' name='gender' value='Male'> Male
<input type='radio' name='gender' value='Female'>Female

这将导致form.reset()失败:

$('input:radio[name=gender][value=Male]').attr('checked', true);

但这条可行:

$('input:radio[name=gender][value=Male]').click();

如果你想从你的模型中传递一个值，并且想要根据值从加载组中选择一个单选按钮，那么使用:

Jquery:

var priority = Model.Priority; //coming for razor model in this case
var allInputIds = "#slider-vertical-" + itemIndex + " fieldset input";

$(allInputIds).val([priority]); //Select at start up

和html:

<div id="@("slider-vertical-"+Model.Id)">
 <fieldset data-role="controlgroup" data-type="horizontal" data-mini="true">
    <input type="radio" name="@("radio-choice-b-"+Model.Id)" id="@("high-"+Model.Id)" value="1" checked="checked">
    <label for="@("high-"+Model.Id)" style="width:100px">@UIStrings.PriorityHighText</label>

    <input type="radio" name="@("radio-choice-b-"+Model.Id)" id="@("medium-"+Model.Id)" value="2">
    <label for="@("medium-"+Model.Id)" style="width:100px">@UIStrings.PriorityMediumText</label>

    <input type="radio" name="@("radio-choice-b-"+Model.Id)" id="@("low-"+Model.Id)" value="3">
    <label for="@("low-"+Model.Id)" style="width:100px">@UIStrings.PriorityLowText</label>
 </fieldset>
</div>
