Ext加载下拉框得志

 

var year_select = new Ext.form.ComboBox({
 id : 'year_select',
 fieldLabel : "學年",
 hiddenName : "year", // 下拉框在 HTML 中显示的名称
 allowBlank : false,
 width : 100,
 selectOnFocus : true,
 valueField : "store", // 提交表单时，下拉框的值
 displayField : 'storeYear', // 显示在页面上下拉框的值
 emptyText : '请选择..',
 editable : false,
 mode : "local",
 forceSelection : true,
 triggerAction : 'all',
 anchor : '85%',
 store : new Ext.data.JsonStore({
 // 动态从后台提取数据并填充到 ComboBox
 autoLoad : true,
 fields : [{
 name : 'store',
 type : 'int'
 }, {
 name : 'storeYear',
 type : 'int'
 }],
 url : '/erips/portfolio/srcs/getYears.htm',
 root : 'root',
 totalProperty : 'totalCount',
 successProperty : 'success',
 failure : function() {
 Ext.Msg.alert("數據加載失敗！請檢查");
 }
 }, []),
 typeAhead : true,
 listeners : {
 select : function(combo, record, index) {
 alert(combo.value);
 }
 }
 });

其中从controller中得到的值为：

{"success":true,"totalCount":1,"root":[2009]}

 

 

var combo = new Ext.form.ComboBox({ width:127, height:50, renderTo:'div_com', mode:'remote', triggerAction:'all', id:'filiale', name:'filiale', value:'请选择..', allowBlank: false, handleHeight:5, listWidth :150, maxHeight:100, readOnly:true, valueFiled:'fid', displayField:'title', store:new Ext.data.JsonStore({ url: '../../MyPages/Colligate/UploadFiliale.aspx?id='+encodeURI(v), root: 'data', fields: ['title','fid'] }), listeners:{ 'select':function(arg){ var d = arg.value; alert(Ext.get("filiale").dom.value); alert(Ext.getCmp("filiale").getValue()); } } });
