jsf

1.本人在写js代码时不知道为什么 只能写成下面这种情况

<h:inputText value="#{user.name}" id="name"
      valueChangeListener="#{user.s}" binding="#{user.ui}"  onmouseout="document.forms.form['form:name'].value='nihao'">

</h:inputText>

而写成onmouseout="document.forms[0].name.value='nihao'"或onmouseout="document.forms.form.elements['name'].value='nihao'"则不行。郁闷中。。。。。。。。。等待高人指点

本人认为是jsf在命名元素时自动将名字加上了form名。即id为name那么 在jsf标签中则为formName：name（form名为formName）

所以改成onmouseout="document.forms.form.elements['form:name'].value='nihao' 则是可以的。

2、

<h:selectManyCheckbox layout="pageDirection"
                       value="#{user.preferColors}">
    <f:selectItems value="#{requestScope.items}"/>
 </h:selectManyCheckbox><p> 

items 、<1>可以提供一个Map对象，Map的key-value会分别作为选项的label-value。<2>可以提供list或数组对象，例如List<SelectItem> 。否则需提供类型转唤器

<%
                    List<SelectItem> list = new ArrayList<SelectItem>();
                    list.add(new SelectItem("11"));
                    list.add(new SelectItem("61"));
                    Map map = new HashMap();
                    map.put("1", "map1");
                    map.put("2", "map2");
                    map.put("4", "map4");
                    map.put("3", "map3");
                    request.setAttribute("list", list);
                    request.setAttribute("map", map);
                    request.setAttribute("s", "ss");
                %>
<p>
                    <h:selectManyCheckbox id="newsletters" layout="pageDirection">
                        <f:selectItem itemValue="1" itemLabel="item1" />
