How to append the HTML code snippet to HTML iframe using jquery? Actually, I have added an HTML code snippet in MySQL Database using PHP. Now I have fetched that HTML Code snippet and trying to append that HTML code snippet in iframe using jquery.
$( document ).ready(function() {
var snippets='<?php echo $snippets_preview; ?>';
$(function() {
var $iframe = $('#iframehtml');
$iframe.ready(function() {
$iframe.contents().find("body").append(snippets);
});
});
});
But I am getting the following error
Uncaught SyntaxError: Invalid or unexpected token
snippets_preview has the following value in it. when I change the value of snippet_preview. it works fine.
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<meta http-equiv="X-UA-Compatible" content="ie=edge">

<script src="//cdnjs.cloudflare.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
<style>'.$postdata['snippets_css'].'</style>
<script>'.$postdata['snippets_javascript'].'</script>
</head>
<body>
'.$ContentDecodedHTML.'
</body>
</html>
If you want to embed html code in an iframe you have to do for example:
JAVASCRIPT (class)
<script>
// -------------------------------------------------------- CLASS
var class_iframe = {
// ------------------------------------- STEP 1 (Create an new Iframe)
generateIframe: function(src, targetDOM){
// ---------------- Create iframe
var newIframe = document.createElement('iframe');
newIframe.onload = function(){
class_iframe.getIframe($('.iframehtml').contents());
};
newIframe.src = src;
newIframe.className = "iframehtml";
newIframe.frameBorder = "0";
// ---------------- Insert iframe in DOM
$(targetDOM).replaceWith(newIframe);
},
// ------------------------------------- STEP 2 (Get iframe in this class)
getIframe: function(iframe){
class_iframe.frame = iframe; console.log(class_iframe.frame);
},
// ------------------------------------- STEP 3 (Append in this iframe)
appendIframe: function(targetInIframe, content){
console.log(class_iframe.frame);
$target = class_iframe.frame.find(targetInIframe); console.log($target);
$target.prepend(content);
},
}
// -------------------------------------------------------- ACTION (loadPage)
$(document).ready(function(){
//$("body").prepend(`<div id="insertIframe"></div>`); //Just for the test
class_iframe.generateIframe("your_url_iframe.html", "#insertIframe");
});
</script>
In your html page
<div id="insertIframe"></div>
JAVASCRIPT (for append in your new iframe)
<script>
// -------------------------------------------------------- ACTION (after loadPage)
class_iframe.appendIframe("html", `<div class="insert">Hello world !</div>`);
</script>
