Question

它实际上是一个外部窗口，第一次单击打开窗口，组合框包含值，但第二次和第三次不再是。我可以知道如何重装我的组合框吗？

尝试重新加载组合框的几种方法，但失败了，请给我一些想法。以下是我的代码。

ViewUserRole = Ext.extend(One.Report, {
reportName : '.ViewUserRoles',
customModelName : 'Standard Role',
autoExecute: true,
isDetailPage: false,
listeners: {
    bbarconfig: function(report, bbarConfig) {
      bbarConfig.items.push({
        xtype: 'button',
        text: 'Create New Role',
        disabled: false,
        listeners: {
            click : function(btn, e) {
                var w = new .CreateNewUserRole();
                w.show();
            }
        }
      });
    }
}
});
One.PageMgr.regDetail('Role', '.ViewUserRole');

首先，

CreateNewUserRole = new Ext.extend(Ext.Window,{

应改为

CreateNewUserRole = Ext.extend(Ext.Window,{

Combobox的定义在哪里，看看它是否有任何问题？您可以在CreateUserRoleForm中为组合框指定静态“id”。

您可以使用storeId -

定义商店

var enterpriseListStore = new Ext.data.JsonStore({
    autoLoad: true,
    storeId : "enterprise-lists",
    url: '/oms/rest/getEntOrgList/getEnterpriseList',
    root    : 'enterprise',
    fields  :[{name: "enterpriseID", type: "int"},{name: "enterpriseName", type: "string"}]
});

var organizationListStore = new Ext.data.JsonStore({
    autoLoad: true,
    storeId : "organization-lists",
    url: '/oms/rest/getEntOrgList/getOrganizationList',
    root    : 'organization',
    fields  :[{name: "organizationID", type: "int"},{name: "organizationName", type: "string"}]
});

这样即使窗户关闭也不会被破坏。
