[英]h:commandLink conditional target
I have a h:commandLink
: 我有一个
h:commandLink
:
<h:commandLink value=""
actionListener="#{controller.authenticateAccount}"
style="text-decoration: none;"
target="#{controller.userNameGiven ? '_parent' : '' }">
<img src="../images/Profile/authenticateCPButton.gif" border="0" style="padding-left: 2px;"/>
</h:commandLink>
Now controller.userNameGiven
is a boolean field and is set to true if username given and otherwise set to false. 现在
controller.userNameGiven
是一个布尔字段,如果提供了用户名,则设置为true,否则设置为false。 The h:commandLink
is present in a iframe and prior to this the target
was set to _parent
and then if the username is present then it was redirecting to a page in the same parent window but in other case the iframe was rendered in the parent page which is clearly a bug. h:commandLink
存在于iframe中,在此之前, target
已设置为_parent
,然后如果存在用户名,则它将重定向到同一父窗口中的页面,但在其他情况下,iframe在父页面中呈现这显然是一个错误。 Now after the target validation the redirected page is opening in that iframe, which is undesirable. 现在,在目标验证之后,重定向页面正在该iframe中打开,这是不可取的。 What I am doing wrong?
我做错了什么?
Thanks and regards. 谢谢并恭祝安康。
Edit 1: 编辑1:
I have changed the target
to: 我已将
target
更改为:
target="#{controller.target}"
where: 哪里:
public String getTarget() {
return target;
}
public void setTarget(String target) {
this.target = target;
}
and 和
if(this.userName != null && this.userName.trim().length()>0) {
target = "_parent";
FacesContext.getCurrentInstance().getExternalContext().redirect("./somepage");
} else {
target = "";
}
But its still not working and the url somepage is opening in the iframe. 但它仍然无法正常工作,并且在iframe中打开了网址网址页面。
Move the logic into a bean method: 将逻辑移到bean方法中:
public class Controller
{
// ...
public boolean isUserNameGiven () { /* snip */ }
public String getFooTarget()
{
return this.isUserNameGiven() ? "_parent" : "";
}
// ...
}
