ExtJS

调用后台代码获取数据，并根据选择的数据触发其它组件

var projectDS = new Ext.data.Store({proxy: new Ext.data.HttpProxy({url: './netmarkets/jsp/com/chipsea/doc/getProject.jsp',method: "post"}),reader: new Ext.data.JsonReader({    // read json dataroot: "result",totalProperty: "totalCount",fields:[{name:"name"},{name:"displayName"}]})});
projectDS.load();var projectCombo = new Ext.form.ComboBox({fieldLabel:'项目',typeAhead: true,triggerAction: 'all',lazyRender:true,mode: 'local',store: projectDS,valueField:'name',displayField:'displayName',listeners: {'select': function () {console.log("select value:" + this.value);var taskDS = new Ext.data.Store({baseParams:{'projectName':this.value},proxy: new Ext.data.HttpProxy({url: './netmarkets/jsp/com/chipsea/doc/getTask.jsp',method: "post"}),reader: new Ext.data.JsonReader({    // read json dataroot: "result",totalProperty: "totalCount",fields:[{name:"task"},{name:"displayTask"}]})});taskCombo.value = '';taskCombo.store = taskDS;taskDS.load();}}});
