jQuery获取所选单选按钮的值

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?

    <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 >

$(function() {
      $("#submit").click(function() {
        alert($('input[name=s_2_1_6_0]:checked').val());
      });
    });`

其他回答

$("#radioID") // select the radio by its id
    .change(function(){ // bind a function to the change event
        if( $(this).is(":checked") ){ // check if the radio is checked
            var val = $(this).val(); // retrieve the value
        }
    });

确保将其包装在DOM就绪函数中($(function(){…});美元(文档)时的功能 (){...});).

获取选中单选按钮值的最简单方法如下:

$("input[name='optradio']:checked").val();

选择器之间不应使用空格。

HTML Code
<input id="is_verified" class="check" name="is_verified" type="radio" value="1"/>
<input id="is_verified" class="check" name="is_verified" type="radio" checked="checked" value="0"/>
<input id="submit" name="submit" type="submit" value="Save" />

Javascript Code
$("input[type='radio'].check").click(function() {
    if($(this).is(':checked')) {
        if ($(this).val() == 1) {
            $("#submit").val("Verified & Save");
        }else{
            $("#submit").val("Save");
        }
    }
});

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();
    }
});
});
