To replace the label of a button when it is clicked, you would need to use JavaScript. Here's an example of how you can do it:

javascript
 
 
Copy code
// HTML
<button id="myButton" onclick="changeLabel()">Click me</button>

// JavaScript
function changeLabel() {
  var button = document.getElementById("myButton");
  button.innerHTML = "18 degrees";
}

In this example, we have a button with an id of "myButton". When the button is clicked, the changeLabel function is called. Inside this function, we use document.getElementById to get the button element and then set its innerHTML property to "18 degrees", changing the label of the button.

To create a form with several questions in HTML, you can use the <form> element along with various input elements to gather the information. Here's an example:

html
 
 
Copy code
<form>
  <label for="name">Name:</label>
  <input type="text" id="name" name="name"><br>

  <label for="email">Email:</label>
  <input type="email" id="email" name="email"><br>

  <label for="age">Age:</label>
  <input type="number" id="age" name="age"><br>

  <label for="gender">Gender:</label>
  <select id="gender" name="gender">
    <option value="male">Male</option>
    <option value="female">Female</option>
    <option value="other">Other</option>
  </select><br>

  <input type="submit" value="Submit">
</form>

In the above example, we have used different input elements such as text input (<input type="text">), email input (<input type="email">), number input (<input type="number">), and select dropdown (<select>). Each input element has a unique id attribute to identify it, and a name attribute to reference its value when submitting the form.

You can add as many questions as you need inside the <form> element. When the user submits the form by clicking the Submit button, the data from the form will be sent to a server-side script for processing.

To replace a button label when the button is clicked, you need to add an onclick event to the button element in JavaScript.

Here's an example code snippet in JavaScript:

javascript
 
 
Copy code
<button onclick="changeLabel()">Click me</button>
<script>
function changeLabel() {
    document.querySelector("button").innerHTML = "Button clicked!";
}
</script>

In this example, the onclick event triggers the changeLabel() function, which selects the button element using document.querySelector() and changes its innerHTML property to a new label "Button clicked!".

This is just a simple example, and there are many other ways to achieve this based on your specific use case.

To change a button label with JavaScript, you can use the innerHTML property to get or set the content inside an HTML element. Here's an example code snippet in JavaScript:

javascript
 
 
Copy code
// HTML button element
const button = document.querySelector('button');

// Change label text
button.innerHTML = 'New Label Text';

In this example, we first select the button element with querySelector(). Then we change the content inside the button element by setting button.innerHTML to the new label text. You can replace 'New Label Text' with whatever label you want.
