I have the html page which is loaded by cef chronium (for wpf) browser. And its content is:
<!DOCTYPE html>

I want to parse this page using HtmlAgility.HtmlDocument but I cannot see any controls (except divisions) in body. They all are loaded by some javascript files declared in header. How can I receive full page contents?
When I open Google Chrome I can press F12 and see all loaded contents. How can I make such things myself?

I have an HTML file linked to a script. A button defined in the HTML has an onclick function 'incrementLabel()' but the function in the script throws the warning:
'incrementLabel' is declared but its value is never read.
function incrementLabel() {
var text = document.getElementById("testLabel").textContent;
document.getElementById("testLabel").innerText = (parseInt(text) + 1);
}

<button onclick="incrementLabel()">Test</button>
<label id="testLabel">0</label>

</html>
I can't find any solutions to the problem other than writing the function in a in HTML. Any help would be much appreciated.
Thanks!

This works perfectly fine. Check if you are importing your JS script correctly.
You can put the javascript code into a before the closing tag .
HTML:
<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">
<link rel="stylesheet" href="styles.css">

<title>Test Web App</title>
</head>
<body>
<button onclick="incrementLabel()">Test</button>
<label id="testLabel">0</label>
<script>
function incrementLabel() {
var text = document.getElementById("testLabel").textContent;
document.getElementById("testLabel").innerText = (parseInt(text) + 1);
}
</script>
</body>
Some of online tools like https://playcode.io don't recognise your code but I have tested in vscode and works fine.
Maybe have to use other online tool or can test if you have imported the code well with a console.log("Works fine") into your javascript file.
Sorry for my english.
I have a styles problem when loading headers, content and footers with jquery.
For some unknown problem, only the content is loaded, regardless of the styles.
The current code:
index.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>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.6.0/jquery.min.js"></script>
<script>
$(function () {
$("#header").load("header/header.html");
$("#footer").load("footer/footer.html");
$("#content").load("content/content.html");
});
</script>
<link rel="stylesheet" type="text/css" href="css.css">
</head>
<body>
<div id="header"></div>
<div id="content"></div>
<div id="footer"></div>
</body>
</html>
Header.html
I get a error js:
(Refused to apply style from 'http://127.0.0.1:XXXX/project/css.css' because its MIME type ('text/html') is not a supported stylesheet MIME type, and strict MIME checking is enabled.)
Although neither "src" or "href" works
<!DOCTYPE html>
<html lang="en">

<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1.0">

<link rel="stylesheet" type="text/css" href="../css.css">

<body class="bodyHeader">

</html>
css.css
.bodyHeader {
background-color: lightblue;
}
.bodyFooter {
background-color: lightslategray;
}
.bodyContent {
background-color: lightyellow;
}
I currently display text without styles.
HEADER
CONTENT
FOOTER
I want to visualize:
DIV [all content, measurements and styles] HEADER
DIV [all content, measurements and styles] CONTENT
DIV [all content, measurements and styles] FOOTER
Without any of them overlapping and respecting the distances.
Is it jquery problem?
I am trying to get an HTML element from 2 different html files. The problem is I only get one of them.
var message1 = document.getElementById("message1") works.
But when I try to do the same for the element in the other html page:
var message2 = document.getElementById("message2") it returns null
I have a main html file (index.html):
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width">
<title>repl.it</title>
<link href="style.css" rel="stylesheet" type="text/css" />
</head>
<body>
<p id = "message1">I hate the post office</p>
<script src="script.js"></script>
</body>
</html>
And I also have another html file (page2.html):
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width">
<title>repl.it</title>
<link href="style.css" rel="stylesheet" type="text/css" />
</head>
<body>
<p id = "message2">Random sentence</p>
<script src="script.js"></script>
</body>
</html>
And finally I have a javascript file (script.js):
//Gets message1 from index.html (works)
var message1 = document.getElementById("message1")
//logs message1 from index.html (works)
console.log(message1)
//gets message2 from page2.html (doesn't work)
var message2 = document.getElementById("message2")
//logs message2 from page2.html (logs null)
console.log(message2)
How do I get the elements of id message and message2 in script.js?
I try this another way using iframe. Add in index.html page
<p id="message">I hate the post office</p>
<iframe src="page2.html" frameborder="0" style="display: none;"></iframe>
<script src="script.js"></script>
Hi I am trying to add a start button via jquery to appear when the page loads. However, the button is not loading.
Here is my code:
$(window).on('load', function() {
const startPage = $("<button id='start'>Go</button>");
$('main').append(startPage);
});

I have a site that should first load external js codes before it executes code in the dom but i wont work. Everytime my external codes load after the js in the body tag what caused problems like undefined classes and variables
index.html
<!DOCTYPE html>
<html lang="en">

<h1>project</h1>
<div id="project"></div>
<script src="./script.js"></script>
</body>
</html>
./project/load.js
window.onload = function() {
var links = ["./project/script1.js", "./project/script2.js", "./project/script3.js"];
for(var link of links) {
var script = document.createElement("script");
script.src = link + "?0";
script.setAttribute("onerror", "reload(this)");
document.head.append(script);
}
}
I tried also with 'addEventListener('DOMContentLoaded', function() {...});' but it did work either.
I hope you can help me.
EDIT 1:
request order
./project/load.js
./script.js
./project/script1.js
./project/script2.js
./project/script3.js
Load your javascript with defer attribute. Replace your HTML with below. The "defer" attribute allows the javascript is run only after the page loading is complete. Meaning the DOM is available
<!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">
<title>Site</title>
<link rel="stylesheet" href="./style.css">
</head>
<body>
<h1>project</h1>
<div id="project"></div>
<script src="./project/load.js" defer></script>
<script src="./script.js" defer></script>
</body>
</html>

Here is what i've done. Please look at this below
HTML
<!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">
<title>Site</title>

<body>
<h1>project</h1>
<div id="project"></div>
<script src="load.js" defer></script>
<script src="script.js" defer></script>
</body>
</html>
Javascript - load.js
(function(){
var dom = document.getElementById("project");
if( dom !== null ){
dom.innerHTML = "<p>Iam load.js " + new Date().toString() + "</p>";
console.log("Iam load.js " + new Date().toString());
}
})();
Javascript - script.js
(function(){
var dom = document.getElementById("project");
if( dom !== null ){
dom.innerHTML = dom.innerHTML + "<p>Iam script.js " + new Date().toString() + "</p>";
console.log("Iam script.js " + new Date().toString());
}
})();
Output
You can see that the order in which i've added the script loads first.
