如何在jquery中获得radiobox的值

<input type="radio" name="religion" class="chk" name="religion" value="muslim">Muslim
<input type="radio" name="religion" class="chk" name="religion" value="christian">Christian
<input type="radio" name="religion" class="chk" name="religion" value="hindu">Hindu

我试过这个，但我没有得到价值，我该怎么做？

var religion = $("name=religion").val();
alert(religion)

Answer 1

你应该通过

获得按下复选框的值

var religion = $("input[name=religion]:checked").val();
alert(religion)

Answer 2

const radio1Value = document.querySelector("input").value;
console.log(radio1Value);

<input type="radio" name="religion" class="chk" name="religion" value="muslim">Muslim
<input type="radio" name="religion" class="chk" name="religion" value="christian">Christian
<input type="radio" name="religion" class="chk" name="religion" value="hindu">Hindu

Answer 3

试试这个

$(document).ready(function(){
        $("input[type='button']").click(function(){
            var radioValue = $("input[name='religion']:checked").val();
            if(radioValue){
                alert("Your are a - " + radioValue);
            }
        });

    });

你有name="religion"两次。您需要将其中一个更改为id="religion"。然后你可以用

访问这个值

var religion = $("#religion").val();
