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οnmοuseοut="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 " />

< f:selectItem itemValue = " 2 " itemLabel = " item2 " />

< f:selectItem itemValue = " 3 " itemLabel = " #{requestScope.s} " />

< f:selectItems value = " #{requestScope.list} " />

</ h:selectManyCheckbox >

</ p >

< h:selectOneMenu id = " shippingOption " required = " true "

value = " #{cashier.shippingOption} " >

< f:selectItem itemValue = " 1 " itemLabel = " item1 " />

< f:selectItem itemValue = " 2 " itemLabel = " item2 " />

< f:selectItem itemValue = " 3 " itemLabel = " #{requestScope.s} " />

< f:selectItems value = " #{requestScope.map} " />

</ h:selectOneMenu >

< p >

< h:selectManyListbox >

< f:selectItem itemValue = " 1 " itemLabel = " item1 " />

< f:selectItem itemValue = " 2 " itemLabel = " item2 " />

< f:selectItem itemValue = " 3 " itemLabel = " #{requestScope.s} " />

< f:selectItems value = " #{requestScope.map} " />

</ h:selectManyListbox >

</ p >
