      Hi

       

      I want to integrate star rating plugin into RichFaces. Here is the JavaScript code

       

       

                          <input name="star1" type="radio" class="star" value="1" />
                    <input name="star1" type="radio" class="star" value="2" />
                    <input name="star1" type="radio" class="star" value="3" />
                    <input name="star1" type="radio" class="star" value="4" />
                    <input name="star1" type="radio" class="star" value="5" />
                    <rich:jQuery selector="#input" query="rating();" />

       

      I want to sumbit the selected value to my backing bean using the following code

       

       

                          <a4j:commandLink 
                            action="#{myBean.setRating(rich:component('star1').value)}"
                            value="#{msg['rating']}">
                        </a4j:commandLink>                   

       

      However I always get empty string as a parameter value. I tried to change name="star1" with id="star1" but without success. Is there any trusted way to do that?

       

      Thanks.

          Try to use a4j:actionparam

          http://docs.jboss.org/richfaces/latest_3_3_X/en/devguide/html/a4j_actionparam.html

          This link says:

          It is possible to use JavaScript expression or function in the "value" attribute. In this case the "noEscape" attribute should be set to "true". The result of this JavaScript invocation is sent to the server as a value of <a4j:actionparam> .

            Thanks, Ilya.

            It works

             

             

            <a4j:commandLink action="#{myController.vote(myBean)}"
                            value="#{msg['rating']}">
                            <a4j:actionparam name="h" value="getSelectedMark()"
                                assignTo="#{myBean.mark}" noEscape="true" />
                        </a4j:commandLink>

    <script type="text/javascript" language="javascript">
        //<![CDATA[
    function getSelectedMark() {
        var rates = document.getElementsByName("rating");
        for (i = 0; i < rates.length; i++) {
            if(rates[i].checked == true) {
                return rates[i].value;
            }
        }

        return 0;
    }
    //]]>    
</script>
