[英]How to pass the selected value of dropdown list from xhtml page to jsf bean?
I have a dropdown list in my wep page, here it is: 我的wep页面中有一个下拉列表,这里是:
<h:form>
<h:panelGrid columns="2">
<h:outputText value="Açılacak hesabın para birimi:"></h:outputText>
<h:selectOneMenu value="currency" >
<f:selectItem itemValue="choose" itemLabel="Seçiniz..." />
<f:selectItem itemValue="tl" itemLabel="Türk Lirası(TL)" />
<f:selectItem itemValue="usd" itemLabel="Amerikan Doları(USD)" />
<f:selectItem itemValue="euro" itemLabel="Euro" />
</h:selectOneMenu>
<h:outputText value="Açılacak hesabın cinsi:"></h:outputText>
<h:selectOneMenu value="vade" >
<f:selectItem itemValue="choose" itemLabel="Seçiniz..." />
<f:selectItem itemValue="vadesiz" itemLabel="Vadesiz mevduat hesabı" />
<f:selectItem itemValue="vadeli" itemLabel="Vadeli Mevduat Hesabı" />
</h:selectOneMenu>
<h:commandButton value="Onayla" action="#{events.createAccount}" ></h:commandButton>
</h:panelGrid>
</h:form>
Then by clicking the button, i will go to Events.java bean and will process some info there. 然后通过单击按钮,我将转到Events.java bean并在那里处理一些信息。 But i need the values of these dropdown lists in the function createAccount().
但是我需要在createAccount()函数中这些下拉列表的值。 Here is my Events bean
这是我的活动bean
@Named(value = "events")
@Dependent
public class Events {
/**
* Creates a new instance of Events
*/
public Events() {
}
public void createAccount(){
}
}
How can i do this? 我怎样才能做到这一点?
Thanks 谢谢
This is a very basic JSF point, in your selectOneMenu
component, define a value in your managed bean: 这是一个非常基本的JSF点,在
selectOneMenu
组件中,在托管bean中定义一个值:
<h:selectOneMenu value="#{events.currency}" >
<f:selectItem itemValue="choose" itemLabel="Seçiniz..." />
<f:selectItem itemValue="tl" itemLabel="Türk Lirası(TL)" />
<f:selectItem itemValue="usd" itemLabel="Amerikan Doları(USD)" />
<f:selectItem itemValue="euro" itemLabel="Euro" />
</h:selectOneMenu>
Now in your managed bean, you just define a property currency
: 现在,在托管bean中,您只需定义一个属性
currency
:
private String currency;
public String getCurrency() {
return currency;
}
public void setCurrency(String currency) {
this.currency = currency;
}
Now in your Events
managed bean's method createAccount
you just use the defined currency
value. 现在,在
Events
托管bean的方法createAccount
您仅使用定义的currency
值。
