I am working on a simple webpage. I have a following sample json file and an HTML template
data.json
{
"NAME":"SAMPLE_NAME",
"ADDRESS":"New Brunswick Avenue"
}
index.html
<div class="name"></div>
<div class="address"></div>
So i have to display the name and address on the template reading from the json file. Is there any library that i can user for this or any other way to accomplish this?
I think you are looking for a compile-time templating or pre-compiled templating engine sort of thing.
You can build one your own with html, css and using javascript or jquery to change the text of certain elements, but this is going to take a long time if you have big pages.
However there is a library out there that does something like this and its called Handlebars.
Heres a link: http://berzniz.com/post/24743062344/handling-handlebarsjs-like-a-pro
This might give you an idea of what it does: What is the difference between handlebar.js and handlebar.runtime.js?
Here is an example using your html:
<script src="https://cdnjs.cloudflare.com/ajax/libs/handlebars.js/4.0.12/handlebars.min.js"></script>
<!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>Document</title>
</head>
<body>
<script>
// Load your html / template into this variable
var template = '<div class="name">{{name}}</div><div class="address">{{address}}</div>';
var jsonData = {
"name":"John",
"address": "City Street"
}
var compiledTemplate = Handlebars.compile(template);
// The output html is generated using
var html = compiledTemplate(jsonData);
document.getElementsByTagName('body')[0].innerHTML = html;
</script>
</body>
</html>
If you would rather write html outside of the javascript variables you could also do it like this:
<script src="https://cdnjs.cloudflare.com/ajax/libs/handlebars.js/4.0.12/handlebars.min.js"></script>
<!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>Document</title>
</head>
<body>
<div id="template">
<div class="name">{{name}}</div>
<div class="address">{{address}}</div>
</div>
<script>
// Load your html / template into this variable
var template = document.getElementById('template').innerHTML;
var jsonData = {
"name":"John",
"address": "City Street"
}
var compiledTemplate = Handlebars.compile(template);
// The output html is generated using
var html = compiledTemplate(jsonData);
document.getElementById('template').innerHTML = html;
</script>
</body>
</html>

I'm using ajax to update a value without refreshing the page.
When I use this html code the website gives an 404 not found error. But when I leave the script tag out of the html, the site works fine and show the p tag. What am i doing wrong in the script tag?

I pretty new on these things and im trying to improve my self on html skeleton. So when I call html skeleton on vscode it's being like this as you know.
<!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>
</body>
</html>
but i want to change default html skeleton content as like this;
<!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>
<style>
body{background-color: black;}
</style>
</head>
<body>
</body>
</html>
Someone can help me with this?
You can make your own custom snippet using vscode.
As in your case you can create one using the following steps:
Open the gear icon on the bottom left of you vscode.
Select user snippet
Type html
Adding your custom html skelton
You can now add this code to have your custom skelton:
"boilerplate": {
"prefix": "log",
body: [
"<!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>",
" <style>",
" body{background-color: black;}",
" </style>",
"</head>",
"<body>",
" ",
"</body>",
"</html>",
],
"description": ""
}
],
"description": "Log output to console"
}
}
I haven't changed the prefix, but it can be changed through "prefix": ""
Using the custom snippet
To use the custom snippet, just type the prefix in the html file to get the results!
If you want to add you own custom code, and have problem in converting it into snippet, here's a website which will help in that:

I am looking to scrape player prices on https://www.fanteam.com/participate/138905/new/e30= using Python and Selenium libraries. I have used the following code:
url = 'https://www.fanteam.com/participate/138905/new/e30='
options = webdriver.ChromeOptions()
options.add_argument('--lang=en')
driver = webdriver.Chrome(chrome_options=options)
driver.get(url)
But I can't get all the players with prices, because I can't find any element on the page(see the picture below
players with prices).

Any code like
el = driver.find_element_by_xpath("//div[#class='player-list']")
return me the error:
NoSuchElementException: Message: no such element: Unable to locate element: {"method":"xpath","selector":"//div[#class='player-list']"}
But when I inspect an element I can see it in the browser.
How to click any element on the page?
The website you are trying to scrape has a shadow-DOM in its html and any html present inside it cannot be accessed and that is the reason you are getting NoSuchElementException.
Currently, selenium does not support the shadow DOM automation, so you need to use javascript in this case to scrape the data.
To get the data using javascript, you can use:
JavascriptExecutor js = (JavascriptExecutor) driver;
String return_value = (String) js.execute_script("return document.getElementByXpath('xpath').innerHTML");

I created an iframe into which I can post formatted text (from a Word document for example) and receive it as html. Is it possible to also recieve the unformatted version (without the html tags), such as created when copying formatted text into a textarea?
My code for logging the html of formatted text:
<!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>Document</title>
<script>
window.addEventListener("load", function () {
var editor = theWYSIWYG.document;
editor.designMode = 'on';
action.addEventListener('click', function() {
var formattedHTML = editor.body.innerHTML
console.log(formattedHTML);
}, false)
}, false)
</script>
</head>
<body>
<div id="textEditor">
<button id="action" title="Bold"><b>Click me</b></button>
<div id="richTextArea"></div>
<iframe id="theWYSIWYG" name="theWYSIWYG" frameborder="0"></iframe>
</div>
</body>
</html>
Technically I could ask the user to also paste the formatted text into a seperate textarea box, but I would prefer to do it in a single time.
Thanks in advance
Try this var text = editor.body.innerText || editor.body.textContent;

While trying to add Expect library in Jsbin.com console, it return undefined.
var mylib = {
text: 'My Category',
scripts: [
{ text: 'My library', url: 'https://github.com/mjackson/expect/blob/master/modules/index.js' }
]
};
libraries.add(mylib);
why don't you add script tag in the head. Try this in jsbin.com
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width">
<title>JS Bin</title>
<script src="https://unpkg.com/expect#%3C21/umd/expect.min.js"></script>
</head>
<body>
<script>
console.log("expect", expect.createSpy)
</script>
</body>
</html>
You may use this stand alone module:
<script src="https://wzrd.in/standalone/expect#22.4.3"></script>
put it in your head tag of the HTML file.
