使用 JS 将 REST 数据附加到矩阵网格

Question

我创建了一个网格/矩阵，我想附加我通过 Fetch 从 SharePoint 列表收集的 JSON 数据。

我为每个方格应用了一个 ID，以便可以附加项目。我到了这个地步，脑子里放了个屁，不知道如何实际输入/附加数据。我不想只在方块上显示文字，当我将鼠标悬停在事件所在的方块上时，我正在考虑使用 (::before and ::after) 伪元素，将弹出一个包含有关事件信息的模式或对话框。

我通过 fetch 提取的数据在 data.d.results 中被格式化为 JSON。

这是数据样本

JSON 响应

{
  "d": {
    "results": [
      {
        "Title": "Pandemic & Natural Disasters",
        "Status": "Active",
        "Priority": "(1) High",
        "Category": "(2)",
        "Likelihood": "5",
        "Consequence": "3"
      },
      {
        "Title": "New Example",
        "Status": "Active",
        "Priority": "(1) High",
        "Category": "(3)",
        "Likelihood": "4",
        "Consequence": "4"
      },
      {
        "Title": "Example #2",
        "Status": "Active",
        "Priority": "(1) High",
        "Category": "(3) Performance (Scope)",
        "Likelihood": "4",
        "Consequence": "3"
      },
      {
        "Title": "Delays",
        "Status": "Active",
        "Priority": "(1) High",
        "Category": "(2) Schedule",
        "Likelihood": "5",
        "Consequence": "2"
      }
    ]
  }
}

所以网格是 5x5，对话框/模态的位置取决于数据值似然（Y 轴）和结果（X 轴）。所以在样本数据中 x=3, y=4 所以它会在黄色方块中。然后在对话框/模态中，文本应显示如下：

-------------------------------------
|               Title               |
|              Category             |
|              Priority             |
|               Status              |
|              Severity       
|
------------------------------------

我怎样才能做到这一点？

如果可能的话，您可以按照此模板修改 DOM 结构并让 5 行包含 5 个框，从而使您更轻松：

  <div class="wrapper">
    <div class="row">
      <div class="box"></div>
      <div class="box"></div>
      ...
    </div>
    <div class="row">
      <div class="box"></div>
      <div class="box"></div>
      ...
    </div>
  </div>

你可以很容易地在 JavaScript 中使用这个函数来获取对应的盒子节点：

const getBoxNode = (x, y) => {
  const rowId = Math.abs(y - 5)
  const row = document.querySelector(`.row:nth-child(${rowId + 1})`)

  return row.querySelector(`.box:nth-child(${x})`)
}

然后您可以将数据添加到此节点：

const appendData = (data) => {
  const {Title, category, Priority, Status, Severity} = data
  const x = data.consequence
  const y = data.likelihood

  const box = getBoxNode(x, y);
  
  // add texts
  [Title, category, Priority, Status, Severity].forEach((text) => {
    const pNode = document.createElement('p')
    pNode.textContent = text
    
    box.appendChild(pNode)
  })
}

完整代码如下：

const risks = {
  "d": {
    "results": [{
        "Title": "Pandemic & Natural Disasters",
        "Status": "Active",
        "Priority": "(1) High",
        "Category": "(2)",
        "Likelihood": "5",
        "Consequence": "3"
      },
      {
        "Title": "New Example",
        "Status": "Active",
        "Priority": "(1) High",
        "Category": "(3)",
        "Likelihood": "4",
        "Consequence": "4"
      },
      {
        "Title": "Example #2",
        "Status": "Active",
        "Priority": "(1) High",
        "Category": "(3) Performance (Scope)",
        "Likelihood": "4",
        "Consequence": "3"
      },
      {
        "Title": "Delays",
        "Status": "Active",
        "Priority": "(1) High",
        "Category": "(2) Schedule",
        "Likelihood": "5",
        "Consequence": "2"
      }
    ]
  }
}




const getBoxNode = (x, y) => {
  const rowId = Math.abs(y - 5)
  const row = document.querySelector(`.row:nth-child(${rowId + 1})`)

  return row.querySelector(`.box:nth-child(${x})`)
}

const appendData = (item) => {
  const {
    Title,
    Category,
    Priority,
    Status,
    Severity
  } = item
  const x = Number(item.Consequence)
  const y = Number(item.Likelihood)

  const box = getBoxNode(x, y);

  // add texts
  [Title, Category, Priority, Status, Severity].forEach((text) => {
    const pNode = document.createElement('p')
    pNode.textContent = text

    box.appendChild(pNode)
  })
}

Promise.resolve(risks)
  .then((data) => {
    data.d.results.forEach((item) => {
      appendData(item)
    });
  });

如果您已经获取数据 - 这意味着您正在使用 javascript。在这种情况下，您可以使用title 属性将信息显示为工具提示。为了简化您查找特定单元格的方式，您可能需要更改ids，以便更容易找到正确的单元格。

这是您提供的数据的示例。将鼠标悬停在 [4,3] 元素上方，您将看到带有数据的工具提示。

const dataFromFetch = {
  "likelihood" : 4, 
  "consequence": 3, 
  "severity" : 12, 
  "category": "Category Name", 
  "Status": "Active", 
  "Title": "This is the Title of the Occurrence", 
  "Priority": "High"
}

document.getElementById( dataFromFetch.likelihood + '-' + dataFromFetch.consequence ).title =  
  dataFromFetch.category + '\n' + 
  dataFromFetch.Status + '\n' + 
  dataFromFetch.Title + '\n' +
  dataFromFetch.Priority
