EXT动态生成fieldset(可适用于动态添加一行等)

Ext.Ajax.request({url : contextPath + "/refreshManager/list",waitMsg : '数据处理中...',success : function(resp, options) {var respText = Ext.util.JSON.decode(resp.responseText);var map = new Map();for(var i=0;i<respText.data.length;i++){if(!map.containsKey(respText.data[i].typeName)){var arr = new Array();arr.push(respText.data[i]);map.put(respText.data[i].typeName,arr);}else{map.get(respText.data[i].typeName).push(respText.data[i]);}}map.each(function(key,value,index){var fieldset = new Ext.form.FieldSet({title: key.trim()+'管理器配置',id: 'fieldSet_' + index});for(var j = 0;j< value.length;j++){var panel = new Ext.Panel({id: 'fieldSet_' + index+'_'+j,layout: 'column',border: false,items : [{columnWidth : .3, border : false,layout : 'form',items : [{xtype : 'compositefield',id : value[j].threadId+'_1',name : value[j].threadId+'_1',fieldLabel : '管理器名称',anchor:'90%', items: [                            {xtype: 'displayfield', value: value[j].threadName}                        ]}/*{xtype : 'textfield',fieldLabel : '管理器名称',id : value[j].threadId+'_1',name : value[j].threadId+'_1',value : value[j].threadName,disabled : true,anchor:'90%'}*/]},{columnWidth : .2, border : false,layout : 'form',items : [{xtype : 'compositefield',id : value[j].threadId+'_2',name : value[j].threadId+'_2',fieldLabel : '推荐周期('+convent(value[j].cycleUnit)+')',anchor:'90%', items: [                            {xtype: 'displayfield', value: value[j].defaultCyleTime}                        ]}/*{xtype : 'textfield',fieldLabel : '推荐周期('+convent(value[j].cycleUnit)+')',id : value[j].threadId+'_2',name : value[j].threadId+'_2',value : value[j].defaultCyleTime,disabled : true,anchor:'90%'}*/]},{columnWidth : .4, border : false,layout : 'form',items : [{xtype : 'numberfield',fieldLabel : '当前周期('+convent(value[j].cycleUnit)+')',id : value[j].threadId+'_3',name : value[j].threadId+'_3',minValue : value[j].minValue,maxValue : value[j].maxValue,value : value[j].cycleTime,anchor:'60%'}]}]});fieldset.add(panel);fieldset.doLayout();}refreshManagerPanel.add(fieldset);refreshManagerPanel.doLayout();    });},failure : function(response, options) {extAlert("error", '系统异常。');}});
