How can I get which radio is selected via jQuery?

我正试图在我的网站上建立一个用户评级制度,但只有第一个数值已经过去,因此,在表格中,评级栏永远是个。这是我与电台合作以来的时期。

这里是我所拥有的。

    <form id="add-rateing">
<input type="radio" name="MOVIE_RATING" value="1" > 1
<input type="radio" name="MOVIE_RATING" value="2" > 2
<input type="radio" name="MOVIE_RATING" value="3" checked="yes"> 3
<input type="radio" name="MOVIE_RATING" value="4" > 4 
<input type="radio" name="MOVIE_RATING" value="5" > 5 <br>
<input type="hidden" name="MOVIE_ID" value="<?php echo $id; ?>">
<input type="hidden" name="MOVIE_TITLE" value="<?php echo $title; ?>">
<input type="hidden" name="USER_ID" value="<?php echo $loggedinusername; ?>">
<input type="submit" value="I Drank To The Credits" onclick="$( #add-rateing ).hide( fast )">
</form>
<script type="text/javascript">
$("#add-rateing").submit(function(event){
event.preventDefault()

addrateing();

 });

function addrateing()
{
var movie_rating_s   = $("#add-rateing [name= MOVIE_RATING ]").val();
var movie_id_s    = $("#add-rateing [name= MOVIE_ID ]").val();
var movie_title_s   = $("#add-rateing [name= MOVIE_TITLE ]").val();
var user_id_s   = $("#add-rateing [name= USER_ID ]").val();
var errors  =   ;

$.ajax({
type    : "POST",
url     : "movie_watched.php",
data    : { rating: movie_rating_s,
            movie  : movie_id_s,
        title: movie_title_s,
            user : user_id_s, },

cache   : false, timeout: 10000,

success  : function() {
    alert("You have played <?php echo $title; ?> ");

},
error    : function() {
    alert("there is a problom");
},
complete : function() {
}

});
};
</script>

Answer 1

引证:

var movie_rating_s   = $("#add-rateing [name= MOVIE_RATING ]").val();

加入:

var movie_rating_s   = $("#add-rateing [name= MOVIE_RATING ]:checked").val();

Answer 2

你们需要选择选定的无线电元素,如:

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

Answer 3

这个问题与贵格·库列斯的遴选人一样。它没有具体说明 gr取“受检查的”无线电纽顿的价值。在装上你的电影时,引证:

var 电影_form_s = 美元[名称=MOVIE_RAting]:checked” val()
