How to remove pagination in jQuery datatable with JavaScript?

Labrador retriever puppy walking on green grass

To remove pagination in jQuery DataTables using JavaScript, we can set the paging option to false when initializing the DataTable.

For example we write:

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <meta name="viewport" content="width=device-width, initial-scale=1.0">
  <title>Remove Pagination in jQuery DataTable</title>
  <link rel="stylesheet" type="text/css" href="https://cdn.datatables.net/1.10.24/css/jquery.dataTables.css">
  <script src="https://code.jquery.com/jquery-3.6.0.min.js"></script>
  <script src="https://cdn.datatables.net/1.10.24/js/jquery.dataTables.js"></script>
</head>
<body>

  <table id="myTable">
    <thead>
      <tr>
        <th>Name</th>
        <th>Age</th>
        <th>Country</th>
      </tr>
    </thead>
    <tbody>
      <tr>
        <td>John Doe</td>
        <td>30</td>
        <td>USA</td>
      </tr>
      <tr>
        <td>Jane Smith</td>
        <td>25</td>
        <td>Canada</td>
      </tr>
      <!-- Add more rows as needed -->
    </tbody>
  </table>

  <script>
    $(document).ready(function() {
      $('#myTable').DataTable({
        paging: false
      });
    });
  </script>

</body>
</html>

In this example, the DataTable is initialized on the <table> element with the ID “myTable”, and the paging option is set to false.

As a result, pagination will be disabled, and all rows will be displayed on a single page.

How to convert an HTML Element to a string with JavaScript?

Labrador retriever puppy walking on green grass

You can convert an HTML element to a string in JavaScript by accessing its outerHTML property.

The outerHTML property returns the HTML representation of the element, including the element itself and its descendants.

For example we write

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <meta name="viewport" content="width=device-width, initial-scale=1.0">
  <title>Convert HTML Element to String</title>
</head>
<body>

  <div id="myDiv">
    <p>This is a paragraph.</p>
    <ul>
      <li>Item 1</li>
      <li>Item 2</li>
      <li>Item 3</li>
    </ul>
  </div>

  <script>
    // Select the element by ID
    var myDiv = document.getElementById("myDiv");

    // Convert the element to a string
    var htmlString = myDiv.outerHTML;

    // Log the HTML string to the console
    console.log(htmlString);
  </script>

</body>
</html>

In this example, the JavaScript code selects the <div> element with the ID “myDiv” and then retrieves its outerHTML property, which contains the HTML representation of the <div> element and its contents.

Finally, it logs the HTML string to the console.

How to add class to HTML element with JavaScript?

Labrador retriever puppy walking on green grass

You can add a class to an HTML element using JavaScript by accessing the element using its ID, class, tag name, or any other suitable selector, and then using the classList property to manipulate its classes.

For example we write:

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <meta name="viewport" content="width=device-width, initial-scale=1.0">
  <title>Add Class with JavaScript</title>
  <style>
    .highlight {
      background-color: yellow;
    }
  </style>
</head>
<body>

  <p id="paragraph">This is a paragraph.</p>

  <script>
    // Select the element by ID
    var paragraph = document.getElementById("paragraph");

    // Add a class to the element
    paragraph.classList.add("highlight");
  </script>

</body>
</html>

In this example, the JavaScript code selects the <p> element with the ID “paragraph” and adds the class “highlight” to it.

As a result, the background color of the paragraph will change to yellow according to the CSS defined for the “highlight” class.

How to make an HTML link that does nothing?

Labrador retriever puppy walking on green grass

To create an HTML link that does nothing when clicked, you can use the href attribute with a value of javascript:void(0);.

This will effectively create a link that, when clicked, executes a JavaScript function that does nothing.

For example we write:

<a href="javascript:void(0);">Click here</a>

This link will appear as clickable text (“Click here”), but clicking on it will not cause any navigation or action to occur.

How to create text input dynamically with JavaScript?

Labrador retriever puppy walking on green grass

We can create a text input dynamically with JavaScript by creating an <input> element and then appending it to the desired parent element in the DOM.

For example, we:

<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Dynamically Create Text Input</title>
</head>
<body>

<div id="container">
  <!-- Text inputs will be added here -->
</div>

<button onclick="addTextInput()">Add Text Input</button>

<script>
function addTextInput() {
  // Create a new input element
  var input = document.createElement("input");
  // Set the type attribute to "text"
  input.type = "text";
  // Optionally, set other attributes such as id, name, placeholder, etc.
  input.placeholder = "Enter your text...";
  
  // Get the parent container where you want to append the input
  var container = document.getElementById("container");
  // Append the input element to the container
  container.appendChild(input);
}
</script>

</body>
</html>

In this example, clicking the “Add Text Input” button triggers the addTextInput() function, which dynamically creates a new <input> element with a type of “text” and a placeholder attribute.

Then, it appends the input element to the <div> element with the id “container”.

We can adjust this code to suit our specific requirements, such as setting other attributes or adding event listeners to the dynamically created input elements.
