ExtJs - 整合百度文章编辑器(ExtJs UEditor)
第一步:去官网下载最新版本的UEditor,UEditor下载。
第二步:在编辑器根目录创建一个Extjs-Editor.js,录入以下代码。
目录结构如下
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">
',
'<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) {
//编辑器各项参数配置,参考UEditor.config.js
me.ue = UE.getEditor(me.getInputId(), Ext.apply(me.ueditorConfig, {
//编辑器高度,可在此处修改,但不要在表单配置中修改,否则滚动条出现后工具栏会消失
initialFrameHeight:320,
initialFrameWidth: '100%',
autoHeightEnabled: false,
enableAutoSave: false,
saveInterval:0
}));
me.ue.ready(function () {
me.UEditorIsReady = true;
});
//这块 组件的父容器关闭的时候 需要销毁编辑器 否则第二次渲染的时候会出问题 可根据具体布局调整
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());
}
},
//返回编辑器实例
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 (前三个是Extjs必须的文件,后三个是编辑器要使用的文件)
<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:创建formPanel
Ext.onReady(function () { //展开树的按钮 Ext.create("Ext.button.Button", { id:"treeBtn",text: "选择父栏目", 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();//显示树 this.setIcon("../Image/expand.png"); } else { treepanel.hide();//隐藏树 this.setIcon("../Image/expand-down.png"); } window.counter += 1; } }); Ext.create("Ext.form.FormPanel", { id:"articleForm", renderTo: "articleEditor", title: '写文章', 1000, style: "padding:10px;", frame: false, border: false, buttonAlign: "center", items: [ { xtype: "fieldset", layout: "column", defaultType: "textfield", style:"margin-top:10px", 950, border: false, fieldDefaults: { labelWidth: 40, labelAlign: "left" }, items: [ { fieldLabel: "标 题", name:"contenTitle", 930, } ] }, { xtype: "fieldset", layout: "column", defaultType: "textfield", style: "margin-top:10px", 950, border: false, fieldDefaults: { labelWidth: 40, labelAlign: "left" }, items: [ { fieldLabel: "作 者", name: "contenAuthor", 930 } ] }, { xtype: "fieldset", layout: "column", defaultType: "textfield", 950, height:450, border: false, fieldDefaults: { labelWidth: 40, labelAlign: "left" }, //编辑器 items: [ { xtype: 'ueditor', fieldLabel: '内 容', id: "content", //不要设置高度,否则滚动条出现后工具栏会消失 930 } ] } ], buttons: [ { text: 'OK', style: "margin-top:20px", handler: function () { } }, { text: "Cancel", style: "margin-top:20px", handler: function () { form.reset(); } } ] }); });
获取编辑器的值
Extjs-Editor.js中我定义了一个返回UEditor实例的方法,如下:
getEditor:function(){
var me=this;
return UE.getEditor(me.getInputId());
}
获取编辑器中的值
要设置编辑器的其它项或获取html值等操作,可参考编辑器根目录下的Index.html源码。这里给个例子,比如获取纯文本:
//找到表单面板中的表单,再find文本框,调用getEditor()即可获得编辑器实例,getContentTxt()获得纯文本
Ext.getCmp("articleForm").getForm().findField("content").getEditor().getContentTxt()
解决下拉框不显示选项的问题
打开编辑器根目录,搜索ueditor.config.js,打开该文件,查找被注释掉的zIndex,把值改为1100000同时去掉注释保存,问题解决。注:以下提供的包是已经更改过zIndex的文件。
