2. 数据提交给php文件的方式:

1)

Ext.Ajax.request({ url:siteRoot+'index.php/fetch_data_XXX/', method:'POST', params:{param1:p1, param2:p2}, //here success:function(response,options) { msgTip.hide(); Ext.Msg.alert("提示", '删除成功!',callBack); function callBack() { window.location.reload(true); } }, failure:function(response,options) { msgTip.hide(); Ext.Msg.alert('提示','请求失败！'); }  

2)

var form = new Ext.form.FormPanel({ baseCls: 'x-plain', labelWidth: 80, fileUpload:true, defaultType: 'textfield', items: [ { xtype: 'textfield', fieldLabel: '选择人物图像', name: 'file', id: 'file', inputType: 'file', allowBlank: false, blankText: '请选择XX.', msgTarget : 'under', anchor: '90%' // anchor width by percentage }, { xtype: 'hidden', name: 'tag', value: tag } ] }); 

var win = new Ext.Window({ x:300, y:200, title: '添加..', width: 400, height:100, layout: 'fit', plain:true, bodyStyle:'padding:5px;', items: form, buttons: [{ text: '提交', handler: function() { form.getForm().submit( { clientValidation:true, waitMsg:'正在上传,请稍候', waitTitle:'提示', url:siteRoot+'index.php/fetch_data_XX/addXX', method:'POST', success: function(form, action) { win.hide(); Ext.Msg.alert('提示','添加成功',callBack); function callBack() { window.location.reload(true); } }, failure: function(form,action) { Ext.Msg.alert('Error', '添加失败'); } }) } }, { text: '关闭', handler:function(){win.hide();} }] }); win.show(); 

3)

var dataRecord = new Ext.data.Record.create([ {name: 'fileName'}, {name: 'filePath'} ]); var dataReader = new Ext.data.JsonReader( { root: 'results', totalProperty: 'total' }, dataRecord ); var dataProxy = new Ext.data.HttpProxy({ url:siteRoot + 'index.php/fetch_data_XXX/XXXl/'+personMd5, method: 'POST' }); var dataStore = new Ext.data.Store({ proxy: dataProxy, reader: dataReader }); dataStore.load(); 

 

3. ExtJS的js代码获取数据参数的方法:

请求为: XXX.html?XXXX.

接受为:

 

var query = location.search.substring(1); //获取查询串 var pos = query.indexOf('&'); var fileMd5 = query.substring(0,pos); var file = query.substring(pos+1);
