我们需要编写帮助面板，客户认为在我们解释它们时将实际(无功能)组件嵌入/内联到帮助文本中是值得的(我同意这一点)。
这对 p:commandButton 和 p:calendar 没有问题，但是每个 p:select* 组件都会导致换行，因为生成的所有 div。
这是一个示例页面:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:ui="http://java.sun.com/jsf/facelets"
xmlns:p="http://primefaces.org/ui">
<h:head>
<title>
D E B U G
</title>
</h:head>
<h:body>
<h:outputStylesheet library="styles" name="project.css" />
<h:outputStylesheet library="styles" name="primefaces-global.css" />
<h:form>
<h:panelGroup layout="block"
styleClass="help-panel">
<p>
The refresh button
<p:commandButton icon="ui-icon ui-icon-refresh"
value="(8)"
global="false"
process="@none"
update="@none">
</p:commandButton>
shows a preview of the number of whatever.
</p>
<p>
The limit select box
<p:selectOneMenu value="#{debugManager.count}"
global="false"
process="@none"
update="@none">
<f:selectItem itemValue="#{50}" itemLabel="50" />
<f:selectItem itemValue="#{100}" itemLabel="100" />
<f:selectItem itemValue="#{200}" itemLabel="200" />
<f:selectItem itemValue="#{500}" itemLabel="500" />
</p:selectOneMenu>
allows you to limit the number of whatever on this page.
</p>
</h:panelGroup>
</h:form>
</h:body>
</html>
这是非常简单的 bean:
@Named
@SessionScoped
public class DebugManager implements Serializable
{
private static final long serialVersionUID = 1L;
private Long count = Long.valueOf( 100 );
public Long getCount()
{
return this.count;
}
public void setCount( Long count )
{
this.count = count;
}
}
这会产生以下内容:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<form id="j_idt6" name="j_idt6" method="post" action="/cmc-compliance/debug.xhtml" enctype="application/x-www-form-urlencoded">
<input type="hidden" name="j_idt6" value="j_idt6" />
<div class="help-panel">
<p>
The refresh button
<button id="j_idt6:j_idt9" name="j_idt6:j_idt9" class="ui-button ui-widget ui-state-default ui-corner-all ui-button-text-icon-left" onclick="PrimeFaces.ab({source:'j_idt6:j_idt9',process:'@none',update:'@none',global:false});return false;" type="submit"><span class="ui-button-icon-left ui-icon ui-icon ui-icon-refresh"></span><span class="ui-button-text">(8)</span></button><script id="j_idt6:j_idt9_s" type="text/javascript">PrimeFaces.cw('CommandButton','widget_j_idt6_j_idt9',{id:'j_idt6:j_idt9'});</script>

<p>
The limit select box
<div id="j_idt6:j_idt11" class="ui-selectonemenu ui-widget ui-state-default ui-corner-all ui-helper-clearfix">
<div class="ui-helper-hidden-accessible">
<select id="j_idt6:j_idt11_input" name="j_idt6:j_idt11_input">
<option value="50">50</option>
<option value="100">100</option>
<option value="200">200</option>
<option value="500">500</option>
</select>
</div>
<label id="j_idt6:j_idt11_label" class="ui-selectonemenu-label ui-inputfield ui-corner-all"> </label>
<div class="ui-selectonemenu-trigger ui-state-default ui-corner-right">
<span class="ui-icon ui-icon-triangle-1-s"></span>
</div>
<div id="j_idt6:j_idt11_panel" class="ui-selectonemenu-panel ui-widget-content ui-corner-all ui-helper-hidden ui-shadow">
<div class="ui-selectonemenu-items-wrapper" style="height:auto">
<ul class="ui-selectonemenu-items ui-selectonemenu-list ui-widget-content ui-widget ui-corner-all ui-helper-reset">
<li class="ui-selectonemenu-item ui-selectonemenu-list-item ui-corner-all">50</li>
<li class="ui-selectonemenu-item ui-selectonemenu-list-item ui-corner-all">100</li>
<li class="ui-selectonemenu-item ui-selectonemenu-list-item ui-corner-all">200</li>
<li class="ui-selectonemenu-item ui-selectonemenu-list-item ui-corner-all">500</li>
</ul>
</div>
</div>
</div>
<script id="j_idt6:j_idt11_s" type="text/javascript">$(function(){PrimeFaces.cw('SelectOneMenu','widget_j_idt6_j_idt11',{id:'j_idt6:j_idt11',effect:'fade'});});</script>
allows you to limit the number of whatever on this page.
</p>
</div>
<input type="hidden" name="javax.faces.ViewState" id="javax.faces.ViewState" value="601711705828338698:-3840718314813237618" autocomplete="off" />
</form>
</body>
</html>
结果是:
我尝试用 span 替换 div，但这会导致选择出现乱码且无法正常工作。
将 style="display: inline-block !important;" 添加到 div 与原来的没有什么不同:
<div id="j_idt6:j_idt11" class="ui-selectonemenu ui-widget ui-state-default ui-corner-all ui-helper-clearfix" style="display: inline-block !important;">
<div class="ui-helper-hidden-accessible" style="display: inline-block !important;">
<select id="j_idt6:j_idt11_input" name="j_idt6:j_idt11_input">
<option value="50">50</option>
<option value="100">100</option>
<option value="200">200</option>
<option value="500">500</option>
</select>
</div>
<label id="j_idt6:j_idt11_label" class="ui-selectonemenu-label ui-inputfield ui-corner-all"> </label>
<div class="ui-selectonemenu-trigger ui-state-default ui-corner-right" style="display: inline-block !important;">
<span class="ui-icon ui-icon-triangle-1-s"></span>
</div>
<div id="j_idt6:j_idt11_panel" class="ui-selectonemenu-panel ui-widget-content ui-corner-all ui-helper-hidden ui-shadow" style="display: inline-block !important;">
<div class="ui-selectonemenu-items-wrapper" style="height:auto" style="display: inline-block !important;">
<ul class="ui-selectonemenu-items ui-selectonemenu-list ui-widget-content ui-widget ui-corner-all ui-helper-reset" style="display: inline-block !important;">
<li class="ui-selectonemenu-item ui-selectonemenu-list-item ui-corner-all">50</li>
<li class="ui-selectonemenu-item ui-selectonemenu-list-item ui-corner-all">100</li>
<li class="ui-selectonemenu-item ui-selectonemenu-list-item ui-corner-all">200</li>
<li class="ui-selectonemenu-item ui-selectonemenu-list-item ui-corner-all">500</li>
</ul>
</div>
</div>
</div>
问:
有没有办法让p:select*不执行“换行”？
PS:PrimeFaces 在 Mojarra 2.1.14 上的版本是 3.4.2。
最佳答案
似乎<p:selectOneMenu>正在生成一堆不必要的 div ，你为什么不使用 <h:selectOneMenu> .
或者您可以添加 .ui-selectonemenu-items-wrapper,.ui-selectonemenu-panel {display:inline}在你的风格。
关于html - PrimeFaces selectOneMenu 无法内嵌到纯文本中(导致换行)，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/15091662/
