javascript - D3 V4 : Updated data is being seen as new data?(更新功能)

coder 2023-08-07 原文

目前正在搭建系统,更新功能遇到了一些问题。

本质上,我正在尝试向 D3 树添加新节点。当用户点击一个节点的“添加按钮”时,可以添加一个新的子节点。每个添加按钮都可以在每个节点的左侧找到。

我关注了 Mike Bostock 的 general update pattern .单击按钮后,唯一的"new"数据元素应该是新创建的子节点,但看起来整个数据都被视为"new"。当我查看每个节点的类名时,我得出了这个结论,并且所有节点都有一个过渡到中心节点并消失的明显事实。其他原始数据应该“更新”,但事实并非如此。任何人都可以轻轻地指出为什么会这样吗?

可以在这个 jfiddle link 中找到我的代码的工作示例.

编辑 06/09

根据 Gordon 的建议,我为我的节点和链接找到了一个唯一字段。因此,为了唯一标识数据,我做了以下更改:

节点

.data(d, d => d.data.name)

链接

.data(d, d => d.source.data.name)

此更改(大部分)有效,但我看到一些奇怪的行为仍在发生:(1) Branch 7.2.1 仍被识别为新节点并消失; (2) 在第二次“添加”左右之后,链接没有与它们各自的节点正确对齐。我认为我的两个小编辑正在影响这一点,因为当我回到原始代码时,线条被正确绘制,尽管它们正在过渡。想法?有什么建议吗?

loadMindMap(parsedList);

最佳答案

有几件事正在发生:

使用唯一键

使用名称不是键的最佳选择,因为每个新节点都有相同的名称(“新子节点”)。相反,最好使用某种 ID 系统。这是一个使用 ID 标记每个节点的数据的快速函数。

let currNodeId = 0;
function idData(node) {
  node.nodeId = ++currNodeId;
  node.children.forEach(idData);
}
idData(parsedList);

并且由于您正在重新定义 parsedData 中的数据,因此您也需要在那里使用 id 属性:

  parsedData = {
    "name": data.name,
    "nodeId": data.nodeId,
    "children": JSON.parse(JSON.stringify(data.children.slice(split_index)))
  };

添加新节点时,也可以在nodeData中设置:

  var newNodeObj = {
    // name: new Date().getTime(),
    name: "New Child",
    nodeId: ++currNodeId,
    children: []
  };

然后实际使用 .nodeId 作为节点的键,将它用作键函数:

    .data(nodes, d => d.data.nodeId);

对于链接,您应该使用 target 而不是 source,因为这是一棵树并且每个 child 只有一个链接(而不是一个有多个链接 parent )。

    .data(nodes, d => d.target.data.nodeId);

防止添加多个节点元素

还有一个问题是在添加新元素之前合并新旧节点。为防止这种情况,您应该更改

node.enter().append("g").merge(node)

到:

node.enter().append("g")

链接转换

最后,您的链接的转换不会随节点一起转换。要使它们过渡,请移动:

    .attr("d", d3.linkHorizontal()
      .x(d => d.y)
      .y(d => d.x));

  linkUpdate.transition()
    .duration(750)

  1. ruby-on-rails - Cucumber 是否只是 rspec 的包装器以帮助将测试组织成功能? - 2

    只是想确保我理解了事情。据我目前收集到的信息,Cucumber只是一个“包装器”,或者是一种通过将事物分类为功能和步骤来组织测试的好方法,其中实际的单元测试处于步骤阶段。它允许您根据事物的工作方式组织您的测试。对吗? 最佳答案 有点。它是一种组织测试的方式,但不仅如此。它的行为就像最初的Rails集成测试一样,但更易于使用。这里最大的好处是您的session在整个Scenario中保持透明。关于Cucumber的另一件事是您(应该)从使用您的代码的浏览器或客户端的角度进行测试。如果您愿意,您可以使用步骤来构建对象和设置状态,但通常您

  2. ruby-on-rails - 使用 javascript 更改数据方法不会更改 ajax 调用用户的什么方法? - 2

    我遇到了一个非常奇怪的问题,我很难解决。在我看来,我有一个与data-remote="true"和data-method="delete"的链接。当我单击该链接时,我可以看到对我的Rails服务器的DELETE请求。返回的JS代码会更改此链接的属性,其中包括href和data-method。再次单击此链接后,我的服务器收到了对新href的请求,但使用的是旧的data-method,即使我已将其从DELETE到POST(它仍然发送一个DELETE请求)。但是,如果我刷新页面,HTML与"new"HTML相同(随返回的JS发生变化),但它实际上发送了正确的请求类型。这就是这个问题令我困惑的

  3. ruby-on-rails - rails 功能测试 - 2

    在Rails自动生成的功能测试(test/functional/products_controller_test.rb)中,我看到以下代码:classProductsControllerTest我的问题是:方法调用products()在哪里/如何定义?products(:one)到底是什么意思?看代码,大概意思是“创建一个产品”,但是它是如何工作的呢?注意我是Ruby/Rails的新手,如果这些是微不足道的问题,我深表歉意。 最佳答案 如果您查看test/fixtures文件夹,您会看到一个products.yml文件。这是在您创建

  5. ruby - 在 Mechanize 中使用 JavaScript 单击链接 - 2

    我有这个:AccountSummary我想单击该链接,但在使用link_to时出现错误。我试过:bot.click(page.link_with(:href=>/menu_home/))bot.click(page.link_with(:class=>'top_level_active'))bot.click(page.link_with(:href=>/AccountSummary/))我得到的错误是:NoMethodError:nil:NilClass的未定义方法“[]” 最佳答案 那是一个javascript链接。Mechan

  6. ruby - Ruby 中允许 "p *1..10"打印出数字 1-10 的功能是什么? - 2

    require'pp'p*1..10这会打印出1-10。为什么这么简洁?您还可以用它做什么? 最佳答案 它是“splat”运算符。它可用于分解数组和范围并在赋值期间收集值。这里收集赋值中的值:a,*b=1,2,3,4=>a=1b=[2,3,4]在此示例中,内部数组([3,4])中的值被分解并收集到包含数组中:a=[1,2,*[3,4]]=>a=[1,2,3,4]您可以定义将参数收集到数组中的函数:deffoo(*args)pargsendfoo(1,2,"three",4)=>[1,2,"three",4]

  7. ruby - 现代计算机的功能是否不足以处理字符串而无需使用符号(在 Ruby 中) - 2

    我读过的关于Ruby符号的每一篇文章都在谈论符号相对于字符串的效率。但是,这不是1970年代。我的电脑可以处理一些额外的垃圾收集。我错了吗?我拥有最新最好的奔腾双核处理器和4GBRAM。我认为这应该足以处理一些字符串。 最佳答案 您的计算机可能能够处理“一点点额外的垃圾收集”,但是当“一点点”发生在运行数百万次的内部循环中时呢?如果它在内存有限的嵌入式系统上运行呢?有很多地方你可以随意使用字符串,但在某些地方你不能。这完全取决于上下文。 关于ruby-现代计算机的功能是否不足以处理字符串

    我看到有关未找到文件min.map的错误消息:GETjQuery'sjquery-1.10.2.min.mapistriggeringa404(NotFound)截图这是从哪里来的? 最佳答案 如果ChromeDevTools报告.map文件的404(可能是jquery-1.10.2.min.map、jquery.min.map或jquery-2.0.3.min.map,但任何事情都可能发生)首先要知道的是,这仅在使用DevTools时才会请求。您的用户不会遇到此404。现在您可以修复此问题或禁用sourcemap功能。修复:获取文

  9. ruby - 如何在 Cucumber 的功能名称中使用空格 - 2

    我正在使用Windows并尝试运行一个现有的功能包,该功能包最初是在MacOS上构建的,这允许他们通过使用带空格的"\"来解决问题。我正在使用Ruby2.2.3和Cucumber。功能名称包含空格,我无法更改它。我尝试使用""和''来绕过空白,但每次都有同样的问题。这是问题的一个例子。如果我运行:cucumberfeatures/'Namecontainingwhitespaces.feature'它工作正常。但是当我运行时:cucumber-pmy_profile和cucumber.yml包含:my_profile:features/'Namecontainingwhitespace

  10. ruby - 如何测试在运行之间提供功能的 Ruby 脚本? - 2

    单元测试的好方法是测试脚本在执行之间保持正确数据的能力——在使用Ctrl-C终止脚本然后重新运行之后?是否有针对执行类似操作的现有模块或脚本的任何测试可以针对最佳实践进行审查? 最佳答案 像http://avdi.org/devblog/2010/07/19/greenletters-painless-automation-and-testing-for-command-line-applications/一样使用库或者期望、运行、终止并重新运行您的程序,并检查它是否运行正确。好的做法是将程序设计为独立的模块,每个模块都经过良好测试
