如何使用JSF / Javascript从inputHidden读取值？

Question

I have a problem with my input in a form. I would like to get a value stored in an inputHidden but it doesn't work.

JSF Code :

<h:form id="testForm">
    <h:selectOneMenu id="list" ...>
               ....
    </h:selectOneMenu>
    <h:inputHidden id="codeShop" value="#{myBean.codeShop}" />
    <h:commandButton immediate="true" value="#{bundle.print}" 
                        onclick="return test();"/>

JS Code :

function test(){
    var codeShop = document.getElementById("testForm:codeShop").value;
    var list = document.getElementById("testForm:list").value;
    ...
}

I succeed to get the selectOneMenu value but document.getElementById("testForm:codeShop") doesn't work.

Generated HTML output :

<input id="testForm:codeShop" type="hidden" name="testForm:codeShop"/>

I don't understand why my value is not in my inputHidden. Is this normal?

Thank you.

使用代码，因为这是通过ID获得价值的正确代码。

function test(){ var codeShop = document.getElementById("codeShop").value; var list = document.getElementById("list").value; ... }
