JXL匯入/匯出
近兩年技術沒有過細化總結，突然心血來潮，隨手來總結一些問題，廢話不多說，切入正題。
jxl匯入匯出這裡主要用的EXTJS+Sh
- 前端：建立按鍵，呼叫觸發事件，根據觸發事件中url找到控制層相對應的路徑
- 按鍵
2.js
/* * 匯入 */ importItem : function() { Ext.QuickTips.init(); Ext.onReady(function() { var form= new Ext.form.FormPanel({ baseCls : 'x-plain', labelWidth : 80, url : cfg.cxt +'/eplantrain/manage/upload/excel.sj', fileUpload : true, defaultType : 'textfield', items : [ { xtype:'fileuploadfield', name: 'file', fieldLabel: '   檔名', labelWidth: 50, msgTarget: 'side', allowBlank: false, anchor: '90%', buttonText:'選擇Excel檔案' },{ xtype: 'label', text: '(請選擇Excel匯入，注意錄入的欄位格式)', style:{ marginLeft:'10px' } } ] }); var win = new Ext.Window({ title : '上傳Excel', width : 400, height : 130, layout : 'fit', plain : true, bodyStyle : 'padding:5px;', buttonAlign : 'center', items : form, buttons : [ { text : '匯入', handler : function() { if (form.form.isValid()) { Ext.MessageBox.show({ title : '請等待', msg : '匯入中...', progressText : '', width : 300, progress : true, closable : false, animEl : 'loding' }); form.getForm().submit({ success : function(form, action) { listView.queryResItem(); Ext.Msg.alert("提示",action.result.msg); win.hide(); }, failure : function(form, action) { Ext.Msg.alert('警告',"Excel匯入失敗！"); win.hide(); } }); } } }, { text : '關閉', handler : function() { win.hide(); } } ] }); win.show(); }); }, /*匯出檔案*/ exportFile: function () { var sm = grid.getSelectionModel(); if (sm.getCount() == 0) { Ext.Mytip.msg('提示', '您尚未選擇要匯出的資料！'); return; } var ids = []; sm.each(function(r) { ids.push(r.data.id); }); // Ext.Msg.confirm('請確認', // '<span style="color:red"><b>提示：</b>確定匯出嗎？</span>', // function(btn,text) { // if (btn == 'yes') { // // Ext.Ajax.request({ // url :cfg.cxt + "/eplantrain/manage/underwrite_export.sj", // // success : function(response) { // // //window.location.href = cfg.cxt + "/eplantrain/manage/exports.sj"; // var rt = Ext.decode(response.responseText); // alert(111+response.responseText.success==true+rt); // if (rt.success) { // listView.queryResItem(); // Ext.Mytip.msg('提示', '匯出成功！'); // } else { // Ext.Mytip.msg('提示', rt.msg); // } // }, // failure : safetys.ajaxError, // params : { // "ids" : ids.join(',') // } // }); // } // }); window.location.href = cfg.cxt + "/eplantrain/manage/exports.sj?ids="+ids; },
