是什么是backbone-js使用语法的优势/原因

//using a Model instance called model

model.get('attribute')

并不是

model.attribute

我刚开始使用骨干,我总是试图直接访问属性

通过角度js 教程,我不明白转发器(功能？)来自茉莉花测试.这是茉莉花还是棱角分明的构造？

页面在<li>元素中确实有一个ng-repeat属性- 但是我没看到它如何转换为测试中对'repeater'的引用

  it('should be possible to control phone order via the drop down select box',
    function() {
    //let's narrow the dataset to make the test assertions shorter
    input('query').enter('tablet');

    //where does  'repeater' below come from?
    expect(repeater('.phones li', 'Phone List').column('phone.name')).
    toEqual(["Motorola XOOM\u2122 with Wi-Fi",
    "MOTOROLA XOOM\u2122"]);

    select('orderProp').option('Alphabetical');


    expect(repeater('.phones li', 'Phone List').column('phone.name')).
    toEqual(["MOTOROLA XOOM\u2122",
    "Motorola XOOM\u2122 with Wi-Fi"]);
    });

错误找不到类型为com.gridsearch.entities.Film的属性find

我需要做一些如下所示的事情; 根据rails中实例对象的值添加jquery效果

("$('#cart').show(2000);") if @cart.total_items ==1

如何配置玻璃鱼以使用应用程序管理的实体管理器？我通过下面给出的配置得到以下错误.

我不希望glassfish管理事务,我只想在持久性单元中使用带有RESOURCE_LOCAL设置的Spring托管事务,而不是JTA

SEVERE: Exception while preparing the app : The persistence-context-ref-name [org.springframework.data.jpa.repository.support.JpaRepositoryFactoryBean/entityManager] .... resolves to a persistence unit called [spring-jpa] which is of type RESOURCE_LOCAL. Only persistence units with transaction type JTA can be used as a container managed entity manager. Please verify your application.

我的配置:

<persistence version="1.0" xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd">

我真的不知道下面的属性controlAggregation用于路由SAPUI5应用程序.没有带有该ID的元素.我在这里找到的演示应用程序中找不到任何"页面"的引用: SAPUI5路由演示

"routing": {
        "config": {
            "routerClass": "sap.m.routing.Router",
            "viewType": "XML",
            "viewPath": "sap.ui.demo.nav.view",
            "controlId": "app",
            "controlAggregation": "pages",   // what does this do?
            "transition": "slide",
            "bypassed": {
                "target": "notFound"
            }

观点定义如下 - 没有提到'页面'

<mvc:View
    controllerName="sap.ui.demo.nav.controller.App"
    xmlns="sap.m"
    xmlns:mvc="sap.ui.core.mvc"
    displayBlock="true">
    <App id="app"/>
</mvc:View>

和

<mvc:View
    controllerName="sap.ui.demo.nav.controller.Home"
    xmlns="sap.m"
    xmlns:mvc="sap.ui.core.mvc">
    <Page title="{i18n>homePageTitle}" class="sapUiResponsiveContentPadding">
        <content>
            <Button id="displayNotFoundBtn" text="{i18n>DisplayNotFound}" press="onDisplayNotFound" class="sapUiTinyMarginEnd"/>
        </content>
    </Page>
</mvc:View>

它在jqgrid文档中声明下面的代码应允许使用服务器端分页进行本地排序; 网格数据在分页时消失; 之前已经问过这个问题没有明确的答案 - 使用loadonce的建议:true表示分页已关闭 - 我需要分页

稍后编辑完整的html页面和json响应(我现在从php/mysql后端运行).

通过默认的'arguments'访问javascript参数并使用诸如'options'之类的显式对象有区别吗？

这两个是否相似,除了那个访问数组参数和另一个访问对象选项？

$.fn.myFn = function(){
  if arguments[0]//....
}

和

$.fn.myFn = function(options){
  if options.value //....
}

这些是来自github上的spring amqp示例, 网址 是https://github.com/SpringSource/spring-amqp-samples.git这些类型的java构造函数是什么类型的？他们是吸气者和制定者的简称吗？

public class Quote {

    public Quote() {
        this(null, null);
    }

    public Quote(Stock stock, String price) {
        this(stock, price, new Date().getTime());
    }

反对这个

public class Bicycle {

public Bicycle(int startCadence, int startSpeed, int startGear) {
    gear = startGear;
    cadence = startCadence;
    speed = startSpeed;
}

我在哪里可以找到使用linq和lambda表达式生成动态sql的好例子？例如,我需要一个方法来获取这些参数

GoupOperator ('And' or 'OR')
A list of objects each with the following parameters:
    SearchColumn.
    SearchValue.
    SearchOperator (equals, contains, does not equal ...)

以及任何特定列升序或降序排序的另一种方法

如果之前已经正确回答了这个问题,我会很乐意将其删除 - 我以前看到的答案都不够全面,对于一个刚接触linq表达式的人来说,插入现有的应用程序时没什么问题 - 谢谢

下面的测试方法出现在spring-guide 教程中。是否有一个不太复杂的语法来编写这个测试，或者我怎样才能把它分解成更小的块？

verify(orderService).createOrder(
      org.mockito.Matchers.<CreateOrderEvent>argThat(
        allOf( org.hamcrest.Matchers.<CreateOrderEvent>
            hasProperty("details",
                hasProperty("dateTimeOfSubmission", notNullValue())),

        org.hamcrest.Matchers.<CreateOrderEvent>hasProperty("details",
                hasProperty("name", equalTo(CUSTOMER_NAME))),

        org.hamcrest.Matchers.<CreateOrderEvent>hasProperty("details",
                hasProperty("address1", equalTo(ADDRESS1))),
        org.hamcrest.Matchers.<CreateOrderEvent>hasProperty("details",
                hasProperty("postcode", equalTo(POST_CODE)))
    )));

试图复制msdn引用在这里不起作用,并给出一个错误,我想增加json序列化的允许长度
