2. 数据提交给php文件的方式:

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！'); \}

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

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);
