Extjs mvc 模式下怎么获得后台传过来的数据。请写详细了谢谢了
extjs是一个前台的组件化的框架，在使用extjs组件时比如datagrid，会有一个url的配置参数，运行时自动请求你这个url，只要你后台传递过来的数据正确会自动显示出来
extjs+mvc给Ext表单添加数据，然后以实体的形式返回到后台
js代码:
Ext.define('app.site.projectWindow', {

配置文件：
action name="project" class="com.szusst.action.site.ProjectAction"
result name="success" type="json"/result
/action
然后就是配置好structs.....基本上就ok 。。。。
extjs+springMVC架构，前台多条记录怎么传递到后台且封装成多个对象
简单说下：1.用Ext.getCmp("id").getValue();等方法获得当前界面中你想传递到后台的值; 2.用formpanel.form.doAction('submit',{ url:'logic.jsp', method:'post', params:, //把需传到后台的数据放在这里。 success : function(form,action){ i
