ExtJs - 整合百度文章編輯器(ExtJs UEditor)
第一步:去官網下載最新版本的UEditor,UEditor下載。
第二步:在編輯器根目錄創建一個Extjs-Editor.js,錄入以下代碼。
目錄結構如下

Ext.define('App.ux.UEditor', { extend: 'Ext.form.field.Text', alias: ['widget.ueditor'], //alternateClassName: 'Ext.form.UEditor', fieldSubTpl: [ '<textarea id="{id}" {inputAttrTpl}', '<tpl if="name"> name="{name}"</tpl>', '<tpl if="rows"> rows="{rows}" </tpl>', '<tpl if="cols"> cols="{cols}" </tpl>', '<tpl if="placeholder"> placeholder="{placeholder}"</tpl>', '<tpl if="size"> size="{size}"</tpl>', '<tpl if="maxLength !== undefined"> maxlength="{maxLength}"</tpl>', '<tpl if="readOnly"> readonly="readonly"</tpl>', '<tpl if="disabled"> disabled="disabled"</tpl>', '<tpl if="tabIdx"> tabIndex="{tabIdx}"</tpl>', // ' class="{fieldCls} {inputCls}" ', '<tpl if="fieldStyle"> style="{fieldStyle}"</tpl>', ' autocomplete="off">\n', '<tpl if="value">{[Ext.util.Format.htmlEncode(values.value)]}</tpl>', '</textarea>', { disableFormats: true } ], ueditorConfig: {}, initComponent: function () { var me = this; me.callParent(arguments); }, afterRender: function () { var me = this; me.callParent(arguments); if (!me.ue) { //編輯器各項參數配置,參考UEditor.config.js me.ue = UE.getEditor(me.getInputId(), Ext.apply(me.ueditorConfig, { //編輯器高度,可在此處修改,但不要在表單配置中修改,否則滾動條出現后工具欄會消失 initialFrameHeight:320, initialFrameWidth: '100%', autoHeightEnabled: false, enableAutoSave: false, saveInterval:0 })); me.ue.ready(function () { me.UEditorIsReady = true; }); //這塊 組件的父容器關閉的時候 需要銷毀編輯器 否則第二次渲染的時候會出問題 可根據具體布局調整 var win = me.up('window'); if (win && win.closeAction == "hide") { win.on('beforehide', function () { me.onDestroy(); }); } else { var panel = me.up('panel'); if (panel && panel.closeAction == "hide") { panel.on('beforehide', function () { me.onDestroy(); }); } } } else { me.ue.setContent(me.getValue()); } }, //返回編輯器實例 getEditor:function(){ var me=this; return UE.getEditor(me.getInputId()); }, setValue: function (value) { var me = this; if (!me.ue) { me.setRawValue(me.valueToRaw(value)); } else { me.ue.ready(function () { me.ue.setContent(value); }); } me.callParent(arguments); return me.mixins.field.setValue.call(me, value); }, getRawValue: function () { var me = this; if (me.UEditorIsReady) { me.ue.sync(me.getInputId()); } v = (me.inputEl ? me.inputEl.getValue() : Ext.value(me.rawValue, '')); me.rawValue = v; return v; }, destroyUEditor: function () { var me = this; if (me.rendered) { try { me.ue.destroy(); var dom = document.getElementById(me.id); if (dom) { dom.parentNode.removeChild(dom); } me.ue = null; } catch (e) { } } }, onDestroy: function () { var me = this; me.callParent(); me.destroyUEditor(); } });
第三步:引入以下文件 (前三個是Extjs必須的文件,后三個是編輯器要使用的文件)
<link href="../scripts/Extjs4.2/resources/css/ext-all-neptune.css" rel="stylesheet" />
<script src="../scripts/Extjs4.2/ext-all.js"></script>
<script src="../scripts/Extjs4.2/ext-lang-zh_CN.js"></script>
<script type="text/javascript" charset="utf-8" src="ExtJsEditor/utf8-net/ueditor.config.js"></script>
<script type="text/javascript" charset="utf-8" src="ExtJsEditor/utf8-net/ueditor.all.min.js"> </script>
<script src="ExtJsEditor/Extjs-Editor.js"></script>
第四部:創建formPanel

Ext.onReady(function () { //展開樹的按鈕 Ext.create("Ext.button.Button", { id:"treeBtn",text: "選擇父欄目", style: "background:red;border:none;", icon: "../Image/expand.png", handler: function () { this.border = false; var columnLabel=Ext.getCmp("columnLabel") var treepanel = Ext.getCmp("dataTree"); if (!window.counter) { window.counter = 1; } if (window.counter % 2 != 0) { treepanel.show();//顯示樹 this.setIcon("../Image/expand.png"); } else { treepanel.hide();//隱藏樹 this.setIcon("../Image/expand-down.png"); } window.counter += 1; } }); Ext.create("Ext.form.FormPanel", { id:"articleForm", renderTo: "articleEditor", title: '寫文章', width: 1000, style: "padding:10px;", frame: false, border: false, buttonAlign: "center", items: [ { xtype: "fieldset", layout: "column", defaultType: "textfield", style:"margin-top:10px", width: 950, border: false, fieldDefaults: { labelWidth: 40, labelAlign: "left" }, items: [ { fieldLabel: "標 題", name:"contenTitle",width: 930, } ] }, { xtype: "fieldset", layout: "column", defaultType: "textfield", style: "margin-top:10px", width: 950, border: false, fieldDefaults: { labelWidth: 40, labelAlign: "left" }, items: [ { fieldLabel: "作 者", name: "contenAuthor", width: 930 } ] }, { xtype: "fieldset", layout: "column", defaultType: "textfield", width: 950, height:450, border: false, fieldDefaults: { labelWidth: 40, labelAlign: "left" }, //編輯器 items: [ { xtype: 'ueditor', fieldLabel: '內 容', id: "content", //不要設置高度,否則滾動條出現后工具欄會消失 width: 930 } ] } ], buttons: [ { text: 'OK', style: "margin-top:20px", handler: function () { } }, { text: "Cancel", style: "margin-top:20px", handler: function () { form.reset(); } } ] }); });
獲取編輯器的值
Extjs-Editor.js中我定義了一個返回UEditor實例的方法,如下:
getEditor:function(){ var me=this; return UE.getEditor(me.getInputId()); }
獲取編輯器中的值
要設置編輯器的其它項或獲取html值等操作,可參考編輯器根目錄下的Index.html源碼。這里給個例子,比如獲取純文本:

//找到表單面板中的表單,再find文本框,調用getEditor()即可獲得編輯器實例,getContentTxt()獲得純文本
Ext.getCmp("articleForm").getForm().findField("content").getEditor().getContentTxt()
解決下拉框不顯示選項的問題
打開編輯器根目錄,搜索ueditor.config.js,打開該文件,查找被注釋掉的zIndex,把值改為1100000同時去掉注釋保存,問題解決。注:以下提供的包是已經更改過zIndex的文件。
