[英]disable jsf tag
I need help disabling this link click without using javascript. 我需要在不使用JavaScript的情况下禁用此链接单击的帮助。 So this is a on jsf page where the beans would set a variable to false then the cancel should not be pressable. 因此,这是在jsf页面上,其中Bean将变量设置为false,然后取消不能被按下。
<p:column style="width:14%; text-align: center;">
<f:facet name="header">
<b><h:outputText value="Action" /> </b>
</f:facet>
<a href="cancel.xhtml?id=#{requestClass.requestID}">
<h:outputText value="Cancel" />
</a>
</p:column>
Thanks in advance! 提前致谢!
Update: 更新:
<p:column style="width:14%; text-align: center;">
<f:facet name="header">
<b><h:outputText value="Action" /> </b>
</f:facet>
<h:link disabled="#{requestBean.cancelledStatus}"
outcome="cancel.xhtml?id=#{requestClass.requestID}" value="Cancel">
<f:param name="id" value="#{requestClass.requestID}" />
</h:link>
</p:column>
that didn't actually disable the button when page is loaded even though status of request is cancelled 即使取消了请求状态,页面加载时实际上并没有禁用按钮
Update 2: this error showing when updated to following: 更新2:更新至以下内容时显示此错误:
<h:commandButton value="Cancel" action="cancel.xhtml?id=#{requestClass.requestID}"
disabled="#{requestBean.cancelledStatus}">
<f:param name="id" value="#{requestClass.requestID}" />
</h:commandButton>
it says: 它说:
/pending.xhtml @86,150 action="cancel.xhtml?id=#{requestClass.requestID}" Not a Valid
Method Expression: cancel.xhtml?id=#{requestClass.requestID}
Instead of using normal HTML tag <a>
, you should use JSF's <h:link>
. 您应该使用JSF的<h:link>
而不是使用普通的HTML标签<a>
。 This tag has the attribute disable
that can be used to disable the link. 该标签具有属性disable
,可用于禁用链接。 In you case, it should look like this: 在这种情况下,它应如下所示:
<h:link disable="#{requestClass.disableCancelLink}" outcome="cancel" value="Cancel">
<f:param name="id" value="#{requestClass.requestID}" />
</h:link>
