- javascript innerHTML
- Example of innerHTML property
The innerHTML attribute serves as a means to generate dynamic HTML content within an HTML document.
It is primarily utilized in web pages to create dynamic HTML elements, including registration forms, comment sections, hyperlinks, and more.
Example of innerHTML property
In this instance, we will construct an HTML form that is triggered when the user clicks on the button.
In this instance, we are programmatically generating the HTML form within the div element that has the identifier mylocation. We determine this location by invoking the document.getElementById function.
Example
<script type="text/javascript" >
function showcommentform() {
var data="Name:<input type='text' name='name'><br>Comment:<br><textarea rows='5' cols='80'></textarea>
<br><input type='submit' value='Post Comment'>";
document.getElementById('mylocation').innerHTML=data;
}
</script>
<form name="myForm">
<input type="button" value="comment" onclick="showcommentform()">
<div id="mylocation"></div>
</form>
Output of the above example
