如何在 JSF 支持 Bean 中获取 tinymce 的值

我在JSF中使用tinymce编辑器，但我不确定如何在我的BackBean中获取此值。如果有人以前使用过这个，请帮助我这样做。

       <script src="resources/tiny_mce/tiny_mce.js" type="text/javascript"></script>
<script type="text/javascript">
    tinyMCE.init({
   // General options
    mode : "textareas",
    theme : "advanced",
    plugins :  "autolink,lists,spellchecker,pagebreak,style,layer,table,save,advhr,advimage,advlink,emotions,iespell,inlinepopups,insertdatetime,preview,media,searchreplace,print,contextmenu,paste,directionality,fullscreen,noneditable,visualchars,nonbreaking,xhtmlxtras,template",
   // Theme options
   theme_advanced_buttons1 :"bold,italic,underline,|,justifyleft,justifycenter,justifyright,justifyfull,|,styleselect,formatselect,fontselect,fontsizeselect",
   theme_advanced_buttons2 : "cut,copy,paste,pastetext,|,bullist,numlist,|,undo,redo,|,link,unlink,anchor,image,cleanup,help,code,|,preview,|,forecolor,backcolor",
   theme_advanced_buttons3 : "tablecontrols,|,hr,removeformat,visualaid,|,sub,sup,|,charmap,iespell,media,advhr,|,styleprops,spellchecker,|,insertfile,insertimage",
   theme_advanced_toolbar_location : "top",
   theme_advanced_toolbar_align : "left",
   theme_advanced_statusbar_location : "bottom",
   theme_advanced_resizing : true,
   // Skin options
   skin : "o2k7",
   skin_variant : "silver",
  content_css : "css/example.css",
 });

   <ice:inputTextarea id="content" value="${bean.passage}" partialSubmit="true"/>

将value="${bean.passage}"替换为 value="#{bean.passage}" 。${}不能调用 setter 方法，但#{}可以。

通过选择器将微小的MCE连接到jsf组件

在下面的示例中，您加载自己的 JavaScript 文件 "loadhtmleditor.js"，其中包含函数 "loadMyEditor（）"。此函数在身体加载中调用。在这个javascript函数中，你通过选择器而不是模式将tinyMCE连接到jsf组件。在选择器参数中，您编写要连接的组件的 html-id。请注意，在此参数中，jsf 生成的 html-id 中的 '：" 分隔符必须用两个反斜杠屏蔽！在此示例中：选择器： "#myForm\\：myHtmlText"

<?xml version="1.0" encoding="UTF-8"?>

    <script src="resources/tiny_mce/tiny_mce.js" type="text/javascript"></script>
    <script src="resources/loadhtmleditor.js" type="text/javascript"></script>
</h:head>
<h:body onload="loadMyEditor();">
    <h:form id="myForm">
        <h:inputTextarea id="myHtmlText" value="#{bean.htmlText}">
        </h:inputTextarea>
    </h:form>
</h:body>
</html>

loadhtmleditor.js：

function loadMyEditor()
{
    tinyMCE.init({
           // General options
            selector : "#myForm\:myHtmlText",
            theme : "advanced",
            plugins :  "autolink,lists,spellchecker,pagebreak,style,layer,table,save,advhr,advimage,advlink,emotions,iespell,inlinepopups,insertdatetime,preview,media,searchreplace,print,contextmenu,paste,directionality,fullscreen,noneditable,visualchars,nonbreaking,xhtmlxtras,template",
           // Theme options
           theme_advanced_buttons1 :"bold,italic,underline,|,justifyleft,justifycenter,justifyright,justifyfull,|,styleselect,formatselect,fontselect,fontsizeselect",
           theme_advanced_buttons2 : "cut,copy,paste,pastetext,|,bullist,numlist,|,undo,redo,|,link,unlink,anchor,image,cleanup,help,code,|,preview,|,forecolor,backcolor",
           theme_advanced_buttons3 : "tablecontrols,|,hr,removeformat,visualaid,|,sub,sup,|,charmap,iespell,media,advhr,|,styleprops,spellchecker,|,insertfile,insertimage",
           theme_advanced_toolbar_location : "top",
           theme_advanced_toolbar_align : "left",
           theme_advanced_statusbar_location : "bottom",
           theme_advanced_resizing : true,
           // Skin options
           skin : "o2k7",
           skin_variant : "silver",
          content_css : "css/example.css",
         });
}

这应该足以将您的 jsf bean 绑定到微小的 MCE 中！

加法：如果你想在用户更改 html 内容时通过 ajax 做出反应，你可以像这样扩展 tinyMCE 编辑器的创建：

loadhtmleditor.js：

function loadMyEditor()
{
    tinyMCE.init({
           // General options
            selector : "#myForm\:myHtmlText",
            theme : "advanced",
            plugins :  "autolink,lists,spellchecker,pagebreak,style,layer,table,save,advhr,advimage,advlink,emotions,iespell,inlinepopups,insertdatetime,preview,media,searchreplace,print,contextmenu,paste,directionality,fullscreen,noneditable,visualchars,nonbreaking,xhtmlxtras,template",
           // Theme options
           theme_advanced_buttons1 :"bold,italic,underline,|,justifyleft,justifycenter,justifyright,justifyfull,|,styleselect,formatselect,fontselect,fontsizeselect",
           theme_advanced_buttons2 : "cut,copy,paste,pastetext,|,bullist,numlist,|,undo,redo,|,link,unlink,anchor,image,cleanup,help,code,|,preview,|,forecolor,backcolor",
           theme_advanced_buttons3 : "tablecontrols,|,hr,removeformat,visualaid,|,sub,sup,|,charmap,iespell,media,advhr,|,styleprops,spellchecker,|,insertfile,insertimage",
           theme_advanced_toolbar_location : "top",
           theme_advanced_toolbar_align : "left",
           theme_advanced_statusbar_location : "bottom",
           theme_advanced_resizing : true,
           // Skin options
           skin : "o2k7",
           skin_variant : "silver",
           init_instance_callback: function (editor)
           {
               editor.on('Change', function(e){myFunctionEditorChanged(editor);});
               editor.on('Paste', function(e){myFunctionEditorPasted(editor);});
           },
           content_css : "css/example.css"
         });
}

function myFunctionEditorChanged(editor)
{
    tinyMCE.triggerSave(); // to be shure, that the changed content is in your jsf-component...
    // do something to trigger an ajax request handeling the changed html content. 
}

function myFunctionEditorPasted(editor)
{
    tinyMCE.triggerSave(); // to be shure, that the changed content is in your jsf-component...
    // do something to trigger an ajax request handeling the changed html content. 
}

通过这种方式，您可以通过 keybord 或粘贴内容对用户输入到 html 编辑器的所有更改做出反应。当用户通过tinyMCE的菜单更改html内容时，我没有找到获得通知的方法。（例如，当用户将某些单词更改为粗体时...
