In this article, I will show you how to download div content using javascript on button click. To save the content of the div you need to trigger the click event and get downloaded from the innerHTML using elementId.
<script type="text/javascript">
function download() {
var a = document.body.appendChild(
document.createElement("a")
);
a.download = "newfile.html";
a.href = "data:text/html," + document.getElementById("content").innerHTML;
a.click(); //Trigger a click on the element
}
</script>
<div style="border: 1px solid #357ae8; width: 500px; height: 350px">
<div id="content">
<h1 style="color: #3d75bd;">Dear user download me....</h1>
<i>click below download button</i>
</div>
<button onclick="download()">Download</button>
</div>
Output:
