使用HTML5的图像按钮

在接下来的文章中，我们将学习关于使用HTML5的图像按钮。

task we are making the image to act as a button, When the user clicks the button, the form is sent to the server. Let's look into it.

什么是图像按钮

图像按钮是通过将<img>标签放置在<button>标签内部创建的，它创建了一个可点击的HTML按钮，并嵌入了图像。

<img> 标签

By using the <img> tag we can include an image on a HTML page. Images are not actually embedded in the webpages; instead, they are connected to them via predetermined paths. The tag consists of two required attributes namely src and alt.

Syntax

Following is the syntax for <img> tag

<img src=”..” alt=”..”>

<button> tag

A clickable button is defined by the <button> tag. You can insert text (as well as tags like <i>, <b>, <strong>, <br> and <img> etc.) inside a <button> element. With a button made with the <input> element, that is not feasible!

Let’s look into the examples for understanding of image button with HTML5.

Example 1

在下面的示例中，我们正在创建一个简单的图像按钮。

<!DOCTYPE html>
<html>
<body>
   <p>Click On The Image</p>
   <button onclick="JavaScript:alert('DONT HUNT ANIMALS')">
   <img width="60" height="40" src="https://www.tutorialspoint.com/coffeescript/images/coffeescript.jpg" alt="animal">
   <br>LOVE ANIMALS</button>
</body>
</html>

When the script gets executed, it will generate an output displaying the image button with text on it along with a prompt on the webpage.

When the user clicks the image button, the event gets triggered and displays an alert "Don’t hunt animals".

Example 2

在下面的示例中，我们使用<input type=” image”>创建了一个图像按钮。

<!DOCTYPE html>
<html>
<body style="text-align: center">
   <h2>creating an image Button with HTML5?</h2>
   <form>
      USERNAME:
      <input type="name" /><br><br>
      PASSWORD:
      <input type="password" /><br><br>
      <input type="image" src=
      "https://www.tutorialspoint.com/images/logo.png"
      height="80px" width="110px"
      alt="submit" />
   </form>
</body>
</html>

When the script gets executed, it will generate an output displaying the input field for username and password along with an image button on the webpage. When the user clicks the image button, the form gets submitted to the server.

Example 3

在下面的示例中，我们使用占位符和一个带有<input type=”image”的图像按钮。

<!DOCTYPE html>
<html>
<head>
   <style>
      input[type='image'] {
         width: 80px;
      }
   </style>
</head>
<body style="text-align: center">
   <p>SIGN IN </p>
   <div>
      <input type="email"
      placeholder="Enter your email Address" />
      <br><br>
   </div>
   <input type="image" id="image" alt="Login"
   src="https://www.tutorialspoint.com/images/logo.png">
</body>
</html>

On running the above script, the output window will pop up, displaying the sign in provided with a placeholder for entering email along with an image button on the webpage.

Example 4

In the following we are creating a image button but inserting <img> tag inside the <button> tag.

<button type = "submit" name = "learn" value = "myimage">
   <p>Tutorials for all</p>
   <img src="https://www.tutorialspoint.com/latest/inter-process-communication.png " />
</button>

运行上述脚本后，它将在网页上生成一个包含文本的图像按钮。
