jQuery Raty get number of stars

Question

I have a simple rating system with jQuery Raty Plugin http://wbotelhos.com/raty/. The user should be able to click on a star, type in a very short text and then click a button. The button has a onClick function: 

<a onclick="submitReview(eventID, stadt)" data-role="button" data-theme="b">Feedback abgeben</a>

This want this function to call eventID, stadt AND the number of stars selected. How is it possible to pass the number of stars to that onClick function? This is my code:

<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
<title>Single page template</title>

<link rel="stylesheet" href="css/jquery.mobile-1.3.1.min.css" />

<script src="js/jquery-1.8.3.min.js"></script>
<script src="js/jquery.mobile-1.3.1.min.js"></script>
</head>

<body>

<div data-role="page" id="menu"> 
<script src="js/functions.js"></script>
<script type="text/javascript" src="js/jquery.raty.js"></script>
<script>
    $(document).delegate('#menu', 'pageshow', function () {
        $('#star').raty();
        stadt = GetURLParameter('stadt');
        document.getElementById('deinestadt').value = stadt; 
        id = GetURLParameter('id');
        getEventFromId(id); 
        getEventText(id);
        eventID = GetURLParameter('id');

        $("a.button").click(function(){
        //Lets say, the Stars are next element to the <a>
        var stars = $(this).next().find("input[name='score']").val();
        submitReview(eventID, stadt, stars);
});

    });
</script>


<div data-role="panel" id="panel">
    <input id="deinestadt" style="text-align:left;" type="search" name="stadt" value="" onfocus="if(this.value=='wo bist du?') this.value=''" id="stadt" value="" />

Solution 2

I got it! I used the callback funktion of the plugin click: function(score, evt){}

This is my markup:

<script>
    $(document).delegate('#menu', 'pageshow', function () {
        $('#star').raty({
            click: function(score, evt) {
            $("#submit_button_review").click(function(){
                submitReview(eventID, stadt, score);
            });
            }
        });
        stadt = GetURLParameter('stadt');
        document.getElementById('deinestadt').value = stadt; 
        id = GetURLParameter('id');
        getEventFromId(id); 
        getEventText(id);
        eventID = GetURLParameter('id');

    });
</script>

and the button:

<a id="submit_button_review"  data-role="button" data-theme="b">Feedback abgeben</a>

Thanks for your help ;)

OTHER TIPS

I just saw that this plugin has hidden value named score, it has the count of star's slected..

Give the a an class like : .button

$("a.button").click(function(){
    //Lets say, the Stars are next element to the <a>
    var stars = $(this).next().find("input[name='score']").val();
    submitReview(eventID, stadt, stars);
});

Didnt test it. Its hard without the markup... Hope it helpd...
