ajaxStatus 仅针对特定组件

问题描述

我使用的是带有 JSF 2.0 的 Primefaces 3.2.

I'm using Primefaces 3.2 with JSF 2.0.

我正在使用

<p:commandButton action="#{myBackingBean.action}" value="press me" />

这对于ajaxStatus:

And this for ajaxStatus:

<p:ajaxStatus onstart="statusDialog.show();"
      onsuccess="statusDialog.hide();"
      rendered="#{myBackingBean.ajaxStatusRendered}"
      id="ajaxStatusField" />

    <p:dialog modal="true" widgetVar="statusDialog"
      header="#{myBackingBean.ajaxStatusHeader}"
      rendered="#{myBackingBean.ajaxStatusRendered}" id="ajaxPanel"
      draggable="false" closable="false">
      <p:graphicImage value="./images/ajaxloader.gif" />
    </p:dialog>

我在同一页面上也有很多其他 primefaces 组件，但我只希望 p:ajaxStatus 在按下此特定按钮时呈现.有什么好的解决办法吗?ajaxStatus 在每个 ajax 事件上呈现..

I've got lots of other primefaces components also on the same page, but I only want the p:ajaxStatus to render when this specific button is pressed. Any good solution to this? The ajaxStatus renders on every ajax event..

推荐答案

如果你有几个按钮，你可以在它们上设置 global="false" 并保留所需的按钮而不用这个设置.

If you have a few amount of buttons, you could set on them global="false" and leave the desired button without this setting.

这样所有其他按钮都不会触发 p:ajaxStatus 而所需的按钮会.

This way all other buttons wouldn't trigger the p:ajaxStatus while the desired button would.
