这是密码-

对于(变量i=0;i
我哪里出错了

PS:我使用的是3.4版本

getValue()
方法有点棘手,它返回的对象根据结果集具有可变结构,这导致了代码中的问题。但是,
getChecked()
方法更简单,我将在解决方案中使用它。 然后,我们使用filterBy,因为它在这种情况下更有用。
这里是解决方案(内联注释):

可选(额外改进,仅适用于ExtJs 4.x)
但是,检查你的应用程序,我认为可以做以下改进:

  • 根据存储数据动态创建筛选器复选框
  • 将“全部”复选框与其余复选框同步(即,选择“全部”时,选择所有其他复选框)
以下是代码及其改进:

var Store1 = new Ext.data.JsonStore({
    proxy: {
        type: 'ajax',                
        url: 'CustomerProfiles/GetDetails',

        load: function(store, records){
