一个Ext2+SWFUpload做的图片上传对话框的例程
我们先看看对话框的布局:
- var Application={};
- Application.uploadDialog={
- progressBarText:'正在上传:{0},{1}%完成',
- statuBarText:'文件总数:{0}个 ,大小:{1}',
- show:function(data){
- if(!this.dialog)
- this.initDialog();
- //this.uploadGrid.store.removeAll();
- if(data)
- this.classStore.loadData(data);
- this.uploadAction[0].enable();
- this.uploadAction[1].disable();
- this.uploadAction[2].disable();
- this.uploadAction[3].disable();
- this.uploadAction[4].enable();
- //this.uploadProgressBar.updateProgress(0,'');
- this.dialog.show();
- },
- hide:function(){
- this.dialog.hide();
- },
- classStore:new Ext.data.SimpleStore({fields: ["id", "text"],data:[]}),
- uploadAction:[
- new Ext.Action({text:'增加',
- handler:function(){
- Application.uploadDialog.swfu.selectFiles();
- }
- }),

- obj.swfu.cancelUpload(rec.data.id);
- store.remove(rec);
- }
- obj.stateInfo.getEl().innerHTML=String.format(obj.statuBarText,obj.uploadGrid.store.getCount(),Ext.util.Format.fileSize(obj.uploadGrid.store.sum('size')));
- if(obj.uploadGrid.store.getCount()==0){

- }
- }}),
- new Ext.Action({text:'清空',disabled:true,handler:function(){

- var store=obj.uploadGrid.store;
- var len=store.getCount();
- for(var i=0;i<len;i++){

在文件里我先定义了一个Application 对象(Application={}),对象为JSON结构,主要方便将应用的各个功能模块作为Application的一个子对象,方便未来调用与区分。当然了,如果你不喜欢的话可以不要这个,不过这文件就要修改不少东西(:))。

- <div id="divDegraded" style="height:0px;width:0px;disply:none;z-index:-2"></div>
- tbar:[Application.uploadDialog.uploadAction[0],Application.uploadDialog.uploadAction[1],Application.uploadDialog.uploadAction[2],
