在js中取選中的radio值

 

<input type="radio" name="address" value="0" />

<input type="radio" name="address" value="1" />

<input type="radio" name="address" value="2" />

 

js中 : var addressID = $("input[name='address']:checked").val();

把radio的name屬性值設置成一樣的，就會變為單選。

 

var radio = document.getElementsByName("DoorCt"); 
    for (i=0; i<radio.length; i++) { 
        if (radio[i].checked) { 
            alert(radio[i].value) 
        } 
    }
