Introduction

When designing a screen that displays a table of campaigns, it's essential to provide users with efficient and intuitive filtering options. In this article, we'll focus on implementing two date filters above a table, specifically for creation and modification dates. By doing so, users can quickly narrow down their search results and focus on the most relevant information.

The Importance of Date Filters

Date filters are a crucial aspect of any data-driven application. They enable users to quickly identify and isolate specific data points based on their creation or modification dates. In the context of a campaign table, date filters can help users:

Identify newly created campaigns
Track changes made to existing campaigns
Analyze campaign performance over time
Make data-driven decisions based on historical data

Designing the Date Filters

When designing the date filters, consider the following best practices:

Use a consistent layout: Ensure that both date filters have a similar layout and design to maintain visual consistency.
Provide clear labels: Use descriptive labels for each date filter to indicate their purpose.
Use a datepicker: Implement a datepicker for each filter to simplify date selection and reduce errors.
Allow for custom date ranges: Provide users with the option to select custom date ranges, rather than being limited to predefined options.

Implementing the Date Filters

To implement the date filters, you can use a variety of libraries and frameworks, depending on your technology stack. Here's a high-level overview of the steps involved:

Choose a datepicker library: Select a suitable datepicker library that integrates well with your application.
Create a date filter component: Design a reusable component for each date filter, including the datepicker and any additional functionality.
Integrate the date filters: Position the date filters above the table, ensuring they are easily accessible and visible.
Add event listeners: Attach event listeners to each date filter to update the table data accordingly.

Example Code

Here's an example of how you might implement the date filters using HTML, CSS, and JavaScript:

<!-- Date filter component -->
<div class="date-filter">
  <label>Creation Date:</label>
  <input type="date" id="creation-date" />
  <button>Apply</button>
</div>
<div class="date-filter">
<label>Modification Date:</label>
<input type="date" id="modification-date" />
<button>Apply</button>
</div>
<!-- Table component -->
<table id="campaign-table">
<!-- Table data -->
</table>

/* Date filter styles */
.date-filter {
  margin-bottom: 20px;
}

.date-filter label {
  display: block;
  margin-bottom: 10px;
}

.date-filter input[type="date"] {
  width: 100%;
  height: 30px;
  padding: 10px;
  border: 1px solid #ccc;
}

.date-filter button {
  width: 100%;
  height: 30px;
  background-color: #4CAF50;
  color: #fff;
  border: none;
  cursor: pointer;
}

.date-filter button:hover {
  background-color: #3e8e41;
}

// Date filter script
const creationDateInput = document.getElementById('creation-date');
const modificationDateInput = document.getElementById('modification-date');
const applyButton = document.querySelectorAll('.date-filter button');

applyButton.forEach((button) => {
  button.addEventListener('click', () => {
    const creationDate = creationDateInput.value;
    const modificationDate = modificationDateInput.value;

    // Update table data based on selected dates
    updateTableData(creationDate, modificationDate);
  });
});

// Update table data function
function updateTableData(creationDate, modificationDate) {
  // Fetch data from API or database
  fetch('/api/campaigns', {
    method: 'GET',
    params: {
      creation_date: creationDate,
      modification_date: modificationDate,
    },
  })
    .then((response) => response.json())
    .then((data) => {
      // Update table data
      const tableBody = document.getElementById('campaign-table').tBodies[0];
      tableBody.innerHTML = '';

      data.forEach((campaign) => {
        const row = document.createElement('tr');
        row.innerHTML = `
          <td>${campaign.name}</td>
          <td>${campaign.creation_date}</td>
          <td>${campaign.modification_date}</td>
        `;
        tableBody.appendChild(row);
      });
    })
    .catch((error) => console.error(error));
}

A: To design effective date filters, follow these best practices:

Use a consistent layout: Ensure both date filters have a similar layout and design to maintain visual consistency.
Provide clear labels: Use descriptive labels for each date filter to indicate their purpose.
Use a datepicker: Implement a datepicker for each filter to simplify date selection and reduce errors.
Allow for custom date ranges: Provide users with the option to select custom date ranges, rather than being limited to predefined options.

Q: How do I implement the date filters in my application?

A: To implement the date filters, follow these steps:

Choose a datepicker library: Select a suitable datepicker library that integrates well with your application.
Create a date filter component: Design a reusable component for each date filter, including the datepicker and any additional functionality.
