ExtJS上传组件中FormPanel能很方便的实现上传。再项目中对单个文件上传实践起来比较的简单
下面是我用这个控件的部分提起出来的部分代码:
<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%> <% String path = request.getContextPath(); String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/"; %> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <head> <base href="<%=basePath%>"> <title>文件上传</title> <link rel="stylesheet" type="text/css" href="./upload/extjs/resources/css/ext-all.css"> <link rel="stylesheet" type="text/css" href="./upload/extjs/UploadDialog/css/Ext.ux.UploadDialog.css"> <script type="text/javascript" src="./upload/extjs/ext-base.js"></script> <script type="text/javascript" src="./upload/extjs/ext-all.js"></script> <script type="text/javascript" src="./upload/extjs/ext-lang-zh_CN.js"></script> <script type="text/javascript" src="./upload/extjs/UploadDialog/UploadDialog.js"></script> </head> <body> <script type="text/javascript"> var uploadForm = new Ext.form.FormPanel({ id:'upload_form', labelAlign:'right', frame:true, height:100, width:380, fileUpload:true, items:[{ id:'fileUploadPath', xtype:'textfield', width:260, height:20, fieldLabel:'上传文件', name:'files', //长传文件名称 inputType:'file' }], buttons:[{ text:'导入', handler:function(){ var path = Ext.getCmp('fileUploadPath').getValue(); //path = './json/upload_filesUpload.action?files=' + path; //path = path.replace(/\\/g,'$'); if(uploadForm.getForm().isValid()){ //uploadForm.getForm().url = path; uploadForm.getForm().url = './json/upload_filesUpload.action'; uploadForm.getForm().submit({ waitMsg: '请稍等...', //ajax请求 success:function(){ /* var conn = new Ext.data.Connection(); conn.request({// 发送异步请求 url : './Food/foodSchool_importReport.action', method : 'POST',//注意大写 params : { 'path' : path }, success : function(rsp, opt) { //导入成功后,利用AJAX执行另一个方法读取excel文件,并显示到页面上 //...... }, failure : function(rsp, opt) { Ext.Msg.alert('异常', '导入失败,请重新选择Excel文件!'); } }); win2.hide(); */ Ext.Msg.alert('提示','上传成功! '); win2.hide(); }, failure:function(){ Ext.Msg.alert('提示','导入失败!'); } }); } } }] }); var btn2 = new Ext.Button({ text:'按钮形式导入', handler:function(){ win2 = new Ext.Window({ id:'uploadFile2', title:'选择导入的文件', modal:true, width:400, height:150, closeAction:'hide', layout:'fit', resizable:false, items:uploadForm }); win2.show(); } }); Ext.onReady(function() { var viewport = new Ext.Viewport({ //layout : 'border', split : true, items:[btn2] }); }) </script> </body> </html>
后台代码的时间请参照我之前写的一片文章,那里有详细的说明。
