Changing Div Background Image with JavaScript

Question:

How can I alter the background image of a div element with JavaScript, using an if-else condition?

Code Snippet:

<code class="html"><div style="text-align:center;">
  <div class="ghor" id="a" onclick="chek_mark()"></div>
  function call
</div>
<script type="text/javascript">
  function chek_mark() {
    var el = document.getElementById("a").style.backgroundImage;
    if (el.url("Black-Wallpaper.jpg")) {
      el.url = "cross1.png";
    } else if (el.url("cross1.png")) {
      alert("<h1>This is working too.");
    }
  }
</script></code>

Clarification:

The goal is to update the background image of the div with class "ghor" based on the current background image.

Answer:

To achieve this, you can use the following code:

<code class="javascript">document.getElementById('a').style.backgroundImage="url(images/img.jpg)";</code>

Explanation:

This code retrieves the div element with id "a" and sets its background-image style property to the specified image path. By replacing "images/img.jpg" with the desired image path, you can change the background image dynamically.

Sample CSS for '.ghor' Class:

<code class="css">.ghor {
    background-image: url('Black-Wallpaper.jpg');
    background-size: cover;
    border-radius: 5px;
    height: 100px;
    width: 100px;
    box-shadow: 2px 5px 7px 7px white;
    display:inline-block; 
}</code>
