我正在尝试在我的应用程序(Ext js 5)中实现jasmine进行单元测试.为此我创建了app-test文件.
Ext.require('Ext.app.Application');Ext.Loader.setConfig({enabled:true});
Ext.onReady(function() {
var Application = Ext.create('Ext.app.Application', {
name: 'epmct',
appFolder:'app',
launch: function() {
Ext.create('epmct.view.vpp.dashboard.VppDashboardMainPage');
}
});
});
当我通过specrunner.html(文件开始单元测试)运行应用程序时,我收到错误
Uncaught Error: [Ext.Loader] Some requested files failed to load.
我尝试使用Ext.Loader.setPath('epmct','app')设置路径; 仍然没有用.
请找到我的specrunner.html文件代码

ERROR [JDBCExceptionReporter] ERROR: function to_date(timestamp without time zone, unknown) does not exist
我通过执行这些to_date函数检查了我的postgres
SELECT to_date(createddate,'YYYY-MM-DD') FROM product_trainings;
它给我错误函数to_date不存在
当我在postgres 8.2中执行相同的查询时,我没有收到错误
请帮我解决这些问题.
我有一个看起来像下面的组合框
{
xtype:'combo',
fieldLabel:'Test',
store:['a','b']
}
在没有创建Ext存储对象的情况下,我将数组分配给存储,并且它正在显示值.
在某些操作,我想用['d','e']更新商店
我试过将新值分配给如下所示的存储
comboObje.store=['d','e'];
但它没有更新值.
如何使用商店中的新值替换原始值.
我在div中有一个标签.
<div id="mydiv">
<label>text</label>
</div>
如何编写选择器来访问标签并更改文本.
