Primefaces 条件工具提示

Primefaces conditional tooltip

<p:spinner id="amount" 

     min="0" 

     max="#{bean.availableAmount}" 

     value="#{bean.amount}" />

<p:tooltip for="amount" 

     showEvent="focus" 

     hideEvent="blur" 

     disabled="#{bean.amount lt bean.maxAmount}" 

     value="Maximum amount has been reached" /><p:spinner id="amount" min="0" max="#{bean.availableAmount}" value="#{bean.amount}"> 

 <p:ajax oncomplete="myTooltip.hide()" process="@this" /> 

</p:spinner>



<p:tooltip id="tooltip"

   for="amount" 

   showEvent="focus" 

   hideEvent="blur" 

   widgetVar="myTooltip"

   value="Maximum amount has been reached" /><p:spinner id="amount" min="0" max="#{bean.availableAmount}" value="#{bean.amount}"> 

 <p:ajax update="tooltip" process="@this" /> 

</p:spinner>



<p:tooltip id="tooltip"

     for="amount" 

     showEvent="focus" 

     hideEvent="blur" 

     rendered="#{bean.amount lt bean.maxAmount}" 

     value="Maximum amount has been reached" />RequestContext context = RequestContext.getCurrentInstance();

context.execute("hideTooltip();");function hideTooltip() {

 $("tooltip").hide();

}

我正在寻找一种方法来实现上面示例中的 disabled 属性之类的东西。换句话说,我想实现一个仅在满足条件时才显示的条件工具提示。有谁知道实现这个的方法吗?


您也可以在客户端使用工具提示的小部件来实现这一点:

<p:spinner id="amount" 

     min="0" 

     max="#{bean.availableAmount}" 

     value="#{bean.amount}" />

<p:tooltip for="amount" 

     showEvent="focus" 

     hideEvent="blur" 

     disabled="#{bean.amount lt bean.maxAmount}" 

     value="Maximum amount has been reached" /><p:spinner id="amount" min="0" max="#{bean.availableAmount}" value="#{bean.amount}"> 

 <p:ajax oncomplete="myTooltip.hide()" process="@this" /> 

</p:spinner>



<p:tooltip id="tooltip"

   for="amount" 

   showEvent="focus" 

   hideEvent="blur" 

   widgetVar="myTooltip"

   value="Maximum amount has been reached" /><p:spinner id="amount" min="0" max="#{bean.availableAmount}" value="#{bean.amount}"> 

 <p:ajax update="tooltip" process="@this" /> 

</p:spinner>



<p:tooltip id="tooltip"

     for="amount" 

     showEvent="focus" 

     hideEvent="blur" 

     rendered="#{bean.amount lt bean.maxAmount}" 

     value="Maximum amount has been reached" />RequestContext context = RequestContext.getCurrentInstance();

context.execute("hideTooltip();");function hideTooltip() {

 $("tooltip").hide();

}

为什么不使用 rendered 而不是 disabled?在这种情况下,您需要在 p:spinner 更改其值时更新 p:tooltip 元素。使用 Primefaces 展示中的 ajax 微调器:

<p:spinner id="amount" 

     min="0" 

     max="#{bean.availableAmount}" 

     value="#{bean.amount}" />

<p:tooltip for="amount" 

     showEvent="focus" 

     hideEvent="blur" 

     disabled="#{bean.amount lt bean.maxAmount}" 

     value="Maximum amount has been reached" /><p:spinner id="amount" min="0" max="#{bean.availableAmount}" value="#{bean.amount}"> 

 <p:ajax oncomplete="myTooltip.hide()" process="@this" /> 

</p:spinner>



<p:tooltip id="tooltip"

   for="amount" 

   showEvent="focus" 

   hideEvent="blur" 

   widgetVar="myTooltip"

   value="Maximum amount has been reached" /><p:spinner id="amount" min="0" max="#{bean.availableAmount}" value="#{bean.amount}"> 

 <p:ajax update="tooltip" process="@this" /> 

</p:spinner>



<p:tooltip id="tooltip"

     for="amount" 

     showEvent="focus" 

     hideEvent="blur" 

     rendered="#{bean.amount lt bean.maxAmount}" 

     value="Maximum amount has been reached" />RequestContext context = RequestContext.getCurrentInstance();

context.execute("hideTooltip();");function hideTooltip() {

 $("tooltip").hide();

}

更新(阅读您的评论后):

如果你想隐藏工具提示,你可以在响应返回浏览器时从服务器端发出命令来执行javascript代码:

<p:spinner id="amount" 

     min="0" 

     max="#{bean.availableAmount}" 

     value="#{bean.amount}" />

<p:tooltip for="amount" 

     showEvent="focus" 

     hideEvent="blur" 

     disabled="#{bean.amount lt bean.maxAmount}" 

     value="Maximum amount has been reached" /><p:spinner id="amount" min="0" max="#{bean.availableAmount}" value="#{bean.amount}"> 

 <p:ajax oncomplete="myTooltip.hide()" process="@this" /> 

</p:spinner>



<p:tooltip id="tooltip"

   for="amount" 

   showEvent="focus" 

   hideEvent="blur" 

   widgetVar="myTooltip"

   value="Maximum amount has been reached" /><p:spinner id="amount" min="0" max="#{bean.availableAmount}" value="#{bean.amount}"> 

 <p:ajax update="tooltip" process="@this" /> 

</p:spinner>



<p:tooltip id="tooltip"

     for="amount" 

     showEvent="focus" 

     hideEvent="blur" 

     rendered="#{bean.amount lt bean.maxAmount}" 

     value="Maximum amount has been reached" />RequestContext context = RequestContext.getCurrentInstance();

context.execute("hideTooltip();");function hideTooltip() {

 $("tooltip").hide();

}

然后在您的 javscript 代码中调用 hideTooltip

<p:spinner id="amount" 

     min="0" 

     max="#{bean.availableAmount}" 

     value="#{bean.amount}" />

<p:tooltip for="amount" 

     showEvent="focus" 

     hideEvent="blur" 

     disabled="#{bean.amount lt bean.maxAmount}" 

     value="Maximum amount has been reached" /><p:spinner id="amount" min="0" max="#{bean.availableAmount}" value="#{bean.amount}"> 

 <p:ajax oncomplete="myTooltip.hide()" process="@this" /> 

</p:spinner>



<p:tooltip id="tooltip"

   for="amount" 

   showEvent="focus" 

   hideEvent="blur" 

   widgetVar="myTooltip"

   value="Maximum amount has been reached" /><p:spinner id="amount" min="0" max="#{bean.availableAmount}" value="#{bean.amount}"> 

 <p:ajax update="tooltip" process="@this" /> 

</p:spinner>



<p:tooltip id="tooltip"

     for="amount" 

     showEvent="focus" 

     hideEvent="blur" 

     rendered="#{bean.amount lt bean.maxAmount}" 

     value="Maximum amount has been reached" />RequestContext context = RequestContext.getCurrentInstance();

context.execute("hideTooltip();");function hideTooltip() {

 $("tooltip").hide();

}
