问题陈述很简单。我需要看看用户是否从无线电组中选择了一个单选按钮。组中的每个单选按钮共享相同的id。

问题是我无法控制表单是如何生成的。下面是单选按钮控件代码的样例代码:

<input type="radio" name='s_2_1_6_0' value='Mail copy to my bill to address' id = "InvCopyRadio" onchange = 'SWESubmitForm(document.SWEForm2_0,s_4,"","1-DPWJJF")' style="height:20;width:25" tabindex=1997 >

除此之外,当单选按钮被选中时,它不会添加一个“checked”属性到控件中,只是文本检查(我猜只是没有值的属性检查)。下面是选定的无线电控件的外观

<input type="radio" checked name='s_2_1_6_0' value='Mail copy to my bill to address' id = "InvCopyRadio" onchange = 'SWESubmitForm(document.SWEForm2_0,s_4,"","1-DPWJJF")' style="height:20;width:25" tabindex=1997 >

有人能帮助我用jQuery代码,可以帮助我得到选中单选按钮的值吗?


当前回答

 <div class="col-md-12">
   <div class="form-radio">
       <input class="radio-outlined" id="accept_new_login1" type="radio" name="aNL" value="1">
       <label for="accept_new_login1" class="radio-teal">Yes</label>
        <input class="radio-outlined" id="accept_new_login2" type="radio" name="aNL" value="0">
        <label for="accept_new_login2" class="radio-teal">No</label>
   </div>
</div>

<script>
  $("input[name=aNL]").on("click" , function () {
    console.log("test" ,$("#accept_new_login").val() , this.value , this.id );
  })

 </script>

这个解决方案不仅简单,还告诉选择的ID和值。你可以检查我的输出。

其他回答

我知道我这么晚才加入。但值得一提的是,它需要

<label class="custom-control-label" for="myRadioBtnName">Personal Radio Button</label>

然后我在js中检查了这个。可以是这样

$(document).ready(function () { 

$("#MyRadioBtnOuterDiv").click(function(){
    var radioValue = $("input[name=myRadioButtonNameAttr]:checked").val();
    if(radioValue === "myRadioBtnName"){
        $('#showMyRadioArea').show();
    }else if(radioValue === "yourRadioBtnName"){
        $('#showYourRadioArea').show();
    }
});
});

`

<div id="subscriptions">
 Company Suscription: <input type="radio" name="subsrad" value="1">
 Customer Subscription:<input type="radio" name="subsrad" value="2">
 Manully Set:<input type="radio" name="subsrad" value="MANUAL">
 NO Subscription:<input type="radio" name="subsrad" value="0">
 </div>

和处理jquery警报的值设置/通过div id更改:

$("#subscriptions input") // select the radio by its id
    .on('change', function(){ // bind a function to the change event
    alert($('input[name="subsrad"]:checked', '#subscriptions').val());
            });

这是如此简单....:-}

 <div class="col-md-12">
   <div class="form-radio">
       <input class="radio-outlined" id="accept_new_login1" type="radio" name="aNL" value="1">
       <label for="accept_new_login1" class="radio-teal">Yes</label>
        <input class="radio-outlined" id="accept_new_login2" type="radio" name="aNL" value="0">
        <label for="accept_new_login2" class="radio-teal">No</label>
   </div>
</div>

<script>
  $("input[name=aNL]").on("click" , function () {
    console.log("test" ,$("#accept_new_login").val() , this.value , this.id );
  })

 </script>

这个解决方案不仅简单,还告诉选择的ID和值。你可以检查我的输出。

举个例子

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1  /jquery.min.js"></script>
<form id="myForm">
<input type="radio" name="radio" value="first"/> 1 <br/>
<input type="radio" name="radio" value="second"/> 2 <br/>
</form>



<script>
$(document).ready(function () {
    $('#myForm').on('click', function () {
        var value = $("[name=radio]:checked").val();

        alert(value);
    })
});
</script>

只看名字

$(function () {
    $('input[name="EventType"]:radio').change(function () {
        alert($("input[name='EventType']:checked").val());
    });
});
