问题 I am trying to input a post code into this website and pull the results into Excel using VBA http://www.freemaptools.com/find-uk-postcodes-inside-radius.htm In short you input a post code and set a radius either in miles or KM and it gives you all the post codes within that area. As you can imagine this tool would be very useful! This is what I have so far: Set ie = CreateObject("InternetExplorer.Application") ie.Visible = 0 url = "http://www.freemaptools.com/find-uk-postcodes-inside-radius

What are React Native's caching behaviors for fetch

こ雲淡風輕ζ 提交于 2019-12-13 19:18:33
问题 What currently are React Native's default behaviors for caching in fetch calls? The official FB guides simply say "look at Mozilla!" but we're not on a web browser. I would assume cache behavior is custom here as result of the middleware. Let's say I do: fetch("https://exampleserver.com/myfile.json") Are requests automatically cached once called? Is the request contents of myfile.json cached the entire "session" (ie: App is running active/bg, but not forced closed by user). Where is the

JPA:Spring Data JPA @OneToMany级联,多方删除修改新增总结(尤其删除操作:添加注解属性orphanRemoval在下一篇解释删除)

一方在oneToMany上设置的级联保存和更新很好理解,多方会随着一方进行保存和更新。但是级联删除其实只是指一方删除时会把关联的多方数据全部删除,并不能删除一方维护的多方list中remove掉的数据。所以本文所讨论的实验和是否设置级联删除是没有关系的。 本文基于实验,我们先设定有如下对象,User为一方,ContactInfo为多方。每个user有多个contactInfo。 所做的操作是先查询User,然后对关联的ContactInfo做增删改。 public class User { @Id @GeneratedValue(strategy = GenerationType.AUTO) private Long id; private String userName; private String password; @Fetch(FetchMode.SUBSELECT) @OneToMany(cascade = CascadeType.ALL, fetch = FetchType.LAZY) @JoinColumn(name = "user_id") private List<ContactInfo> contactInfos = new ArrayList<>(); } public class ContactInfo { @Id @GeneratedValue

Show fetch results in render return() in React.js

回眸只為那壹抹淺笑 提交于 2019-12-13 14:24:23
问题 My question is about how to show array results in render return(). I made a fetch to the API and now I get results that get stored in a array. I need to show this results but I tried with a for{} inside the return and it doesn't work, and I also tried with .map and the map is undefined . fetch(url + '/couch-model/?limit=10&offset=0', { method: 'GET', headers: { 'Content-Type': 'application/json', 'Accept': 'application/json', 'Authorization': 'JWT ' + (JSON.parse(localStorage.getItem('token')

ajax和axios、fetch的区别

1.jQuery ajax $.ajax({ type: 'POST', url: url, data: data, dataType: dataType, success: function () {}, error: function () {} }); 传统 Ajax 指的是 XMLHttpRequest(XHR), 最早出现的发送后端请求技术,隶属于原始js中,核心使用XMLHttpRequest对象,多个请求之间如果有先后关系的话,就会出现 回调地狱 。 JQuery ajax 是对原生XHR的封装,除此以外还增添了对 JSONP 的支持。经过多年的更新维护,真的已经是非常的方便了,优点无需多言;如果是硬要举出几个缺点,那可能只有: 1.本身是针对MVC的编程,不符合现在前端 MVVM 的浪潮 2.基于原生的XHR开发,XHR本身的架构不清晰。 3.JQuery整个项目太大,单纯使用ajax却要引入整个JQuery非常的不合理(采取个性化打包的方案又不能享受CDN服务) 4.不符合关注分离(Separation of Concerns)的原则 5.配置和调用方式非常混乱,而且基于事件的异步模型不友好。 PS:MVVM(Model-View-ViewModel), 源自于经典的 Model–View–Controller(MVC)模式。MVVM 的出现促进了 GUI
