Here is the task to insert HTML content into an iFrame using jQuery. To do so, we can use the jQuery contents() method. 

The .contents() method: It returns all the direct children, including text and comment nodes for the selected element. 

Syntax:

$(selector).contents()
  • Find the iframe in the body section.
  • Get the value to be inserted in the iframe in the body section
  • Place the value in the iframe

jQuery code to show the working of this approach: 

Example 1: 

html

<script src=
</script>
<style type="text/css">
    textarea,
    iframe {
        display: block;
        margin: 10px 0;
    }
      
    iframe {
        width: 500px;
        border: 1px solid #000000;
    }
</style>
<h1 style="color:green;">

<textarea rows="2" cols="40" style="text-align:center;">
        GEEKSFORGEEKS - A computer science portal for geeks.
    </textarea>
<button type="button" onclick="updateIframe()">

</button>
<iframe style="text-align:center;" id="myframe"></iframe>
<script type="text/javascript">
    function updateIframe() {
        var myFrame = $("#myframe").contents().find('body');
        var textareaValue = $("textarea").val();
        myFrame.html(textareaValue);
    }
</script>
