Ext自己带了一个HtmlEditor,具备基本的编辑功能,而且使用起来非常方便,在web应用起来感觉还不错,但是他缺少了上传功能,这样使得编辑文字的时候不能图文并茂,写一个小工程个人认为不需要集成FCK或者其他的编辑器,使用这个足矣,所以在闲暇之余给HtmlEditor写了一个扩展代码,使得htmlEditor具备图片上传功能,并及时给图片插入到文字中间,代码如下:
HTMLEditor=Ext.extend(Ext.form.HtmlEditor,{
codeStyle:'<br/><pre style="border-right: #999999 1px dotted; padding-right: 5px; border-top: #999999 1px dotted; padding-left: 5px; font-size: 12px; padding-bottom: 5px; margin-left: 10px; border-left: #999999 1px dotted; margin-right: 10px; padding-top: 5px; border-bottom: #999999 1px dotted; background-color: #eeeeee">{0}</pre><br/>',
onRender : function(ct, position){
HTMLEditor.superclass.onRender.call(this, ct, position);
if(this.keys){
if(!this.keys.length){
this.keyMap = new Ext.KeyMap(this.getEditorBody(), this.keys);
}
else{
this.keyMap = new Ext.KeyMap(this.getEditorBody(),this.keys[0]);
for(var i=1;i<this.keys.length;i++)this.keyMap.addBinding(this.keys[i]);
}
this.keyMap.stopEvent=true;
}
},
addImage:function(){
function insertImage(){
var editor=this;
//editor.insertAtCursor("<br/><img src='upload/IMG_1198.JPG'/></br>");
win.upload(function(ret){
if(ret){
s="<br/><img src="+ret.path;
if(ret.width)s+=" width="+ret.width;
if(ret.height)s+=" height="+ret.height;
s+=" /><br/>";
editor.insertAtCursor(s);
win.close();
}
});
};
var win=new UploadImageWindow({modal:false,iconCls:"icon-img",
buttons:[{text:"确定",handler:insertImage,scope:this},{text:"取消",handler:function(){win.close();}}]});
win.show();
},
addCode:function(){
function insertCode(){
var value=win.getComponent("codes").getValue();
this.insertAtCursor(String.format(this.codeStyle,value));
win.close();
};
var win=new Ext.Window({title:"添加代码",
width:500,
height:300,
modal:true,
iconCls:"icon-code",
layout:"fit",
items:{xtype:"textarea",id:"codes"},
buttons:[{text:"确定",handler:insertCode,scope:this},{text:"取消",handler:function(){win.close();}}]});
win.show();
},
createToolbar:function(editor){
HTMLEditor.superclass.createToolbar.call(this,editor);
this.tb.insertButton(16,{cls:"x-btn-icon",
icon:"resources/resources/images/default/dd/img.png",handler:this.addImage,scope:this});
this.tb.insertButton(18,{cls:"x-btn-icon",
icon:"resources/resources/images/default/dd/code.png",handler:this.addCode,scope:this});
},
validateValue : function(value){
if(value.length > this.maxLength){
var s=String.format(this.maxLengthText, this.maxLength);
this.markInvalid(s);
return false;
}
return true;
}
});
UploadImageWindow=Ext.extend(Ext.Window,{
title : '上传图片',
width : 345,
height : 210,
defaults : {
border : false
},
buttonAlign : 'center',
createFormPanel :function() {
return new Ext.form.FormPanel({

upload:function(fn) {
this.fp.form.submit({

waitMsg : '正在上传......',

success : function(form, action) {
this.fp.form.findField("path").setValue("/upload/"+action.result.data.path);
