I use Google Code Prettify to syntax highlight my code. This is my HTML
<head>
<script src="https://cdn.rawgit.com/google/code-prettify/master/loader/run_prettify.js"></script>
</head>
<body>
<div id ="xmlView">
<pre class="prettyprint">
<code class="language-xml" id="xmlTextArea"></code>
</pre>
</div>
</body>
When adding Code directly in HTML to xmlTextArea and replacing all < and > with > and < it does it's job, but not when setting the code with jquery like this:
$('#xmlTextArea').text(code)
I also tried to call PR.prettyPrint() afterwards
Here is the pretty code. You can refer to code-prettify for more examples:
var someCode = 'class Voila {public:static const string VOILA = "Voila";tags.}';
$('.prettyprint').html(someCode);
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<head>
<script src="https://cdn.rawgit.com/google/code-prettify/master/loader/run_prettify.js"></script>
</head>
<body>
<div id="xmlView">
<pre class="prettyprint"></pre>
</div>
</body>

I created this very basic example of a jquery html() function but it doesn't work:
<html>
<head>
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js"></script>
<script>
var html = "<div>Test</div>";
$('#TestDiv').html(html);
</script>
</head>
<body>
<div id="TestDiv" style="height:50px;width:50px;border:1px solid black;"></div>
</body>
</html>
View on JSBin
Any idea what the issue might be?
You miss put it on docmuent ready
<html>
<head>
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js"></script>
<script>
$(document).ready( function()
{
var html = "<div>Test</div>";
$('#TestDiv').html(html);
}
);
</script>
</head>
<body>
<div id="TestDiv" style="height:50px;width:50px;border:1px solid black;"></div>
</body>
</html>
put your script after div tag
or if you want to keep the script within the head tag then you need to included it in $(), like so:
I have created a VERY simple program on a VERY simple html file. I wish to simply find out how to link javascript to html and css. Here follows my example code:
(index.html)
<head>
<title>JavaScript</title>
<link rel="stylesheet" href="stylesheet.css"/>
</head>
<body>
<div class="picture">
<img src="https://encrypted-tbn1.gstatic.com/images?q=tbn:ANd9GcRZAb6KcZrNTBM1UflIMAQfAGuTKN0XWYFsiTgm5M5NRwXO_udT"/>
</div>
<button class="show_btn">Show</button>
<button class="hide_btn">Hide</button>
<script src="script.js"></script>
</body>
JS:
$(document).ready(function(){
$(".hide_btn").click(function(){
$("p").slideUp();
});
$(".show_btn").click(function(){
$("p").slideDown();
});
});
CSS:
.picture { display: none; }
Now with this code, I am attempting to use two buttons to show and hide a picture of a fish...I can't seem to get it to work however, and I believe it has something to do with how I am linking my files. Please Help!
Based off of your comment in your question it would appear that you are using jQuery but you do not have jQuery as part of your source code.
You will need to include the jQuery source above script.js.
Here is an example of how it should look like using Google CDN for the jQuery library:
<head>
<title>JavaScript</title>
<link rel="stylesheet" href="stylesheet.css"/>
</head>
<body>
<div class="picture">
<img src="https://encrypted-tbn1.gstatic.com/images?q=tbn:ANd9GcRZAb6KcZrNTBM1UflIMAQfAGuTKN0XWYFsiTgm5M5NRwXO_udT"/>
</div>
<button class="show_btn">Show</button>
<button class="hide_btn">Hide</button>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.3/jquery.min.js"></script>
<script src="script.js"></script>
</body>
try this in javascript
<html>
<head>
</head>
<body>
<div class="picture" id="picture">
<img src="https://encrypted-tbn1.gstatic.com/images?q=tbn:ANd9GcRZAb6KcZrNTBM1UflIMAQfAGuTKN0XWYFsiTgm5M5NRwXO_udT" />
</div>
<button class="show_btn" onclick="show();">Show</button>
<button class="hide_btn" onclick="hide();">Hide</button>
<script type="text/javascript" >
function show(){
var imgdiv = document.getElementById("picture");
imgdiv.style.display="block";
}
function hide(){
var imgdiv = document.getElementById("picture");
imgdiv.style.display="none";
}
</script>
</body>
</html>
I would definitely use jQuery for something like this. Here's a Plunker that shows how you can accomplish this.
http://embed.plnkr.co/DwTwNuF162rfgcQOdT7u/preview
<html>
<head>
<script data-require="jquery#*" data-semver="2.1.3" src="http://code.jquery.com/jquery-2.1.3.min.js"></script>
<link rel="stylesheet" href="style.css" />
<script src="script.js"></script>
</head>
<body>
<div class="picture" id="picture">
<img src="https://encrypted-tbn1.gstatic.com/images?q=tbn:ANd9GcRZAb6KcZrNTBM1UflIMAQfAGuTKN0XWYFsiTgm5M5NRwXO_udT" />
</div>
<button class="show_btn" onclick="show()">Show</button>
<button class="hide_btn" onclick="hide()">Hide</button>
</body>
<script>
function show() {
$('#picture').show();
}
function hide() {
$('#picture').hide();
}
</script>
</html>
If you are using jquery you also need to link the jquery source above your .js link,
here is the google cdn (so you dont have to download it):
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.2/jquery.min.js"></script>
First things first:
Include this in your <head>:
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.2/jquery.min.js"></script>
If you're on Chrome try using the developer tools; right click on the page then inspect element. On the developer tools pane, select the CONSOLE tab which logs all your errors in your javascript
And try this in your script:
$(document).ready(function() {
$(".show_btn").click(function() {
$(".picture").css('display', 'block');
});
$(".hide_btn").click(function() {
$(".picture").css('display', 'none');
});
});
Also I've noticed that you have div.picture display set to "none".
All that you need to do is the following
<script type="text/javascript"></script>
You can write javascript inside the script tags. (if you want to add javascript in HTML
the following is to link it to another file.
<script src="path to other file" > </script>
What I am trying to accomplish is, using jQuery, dynamically replace the content (generated from another javascript) of div tag with id="Test".
<html>
<head>
<script type="text/javascript" src="http://code.jquery.com/jquery-latest.pack.js"></script>
<script type="text/javascript">
$(function(){
$("#Test").html('<b>test content</b>');
});
</script>
</head>
<body id="testAgain">
begin
<div class="scrollable">
<div class="items" id="Test">
</div>
</div>
end
</body>
</html>
As you can see,
$("#Test").html('<b>test content</b>');
replaces the html code of div tag with id="Test" with html code
<b>test content</b>
this works perfectly fine. I am getting rendered html as
begin
test content
end
<html>
<head>
<script type="text/javascript" src="http://code.jquery.com/jquery-latest.pack.js"></script>
<script type="text/javascript">
function TestScript(){
document.write('<b>test content</b>');
};
</script>
<script type="text/javascript">
$(function(){
$("#Test").html(TestScript());
});
</script>
</head>
<body id="testAgain">
begin
<div class="scrollable">
<div class="items" id="Test">
</div>
</div>
end
</body>
</html>
Here,
$("#Test").html(TestScript());
replaces the html code of div tag with id="Test" with generated html from javascript
TestScript()
I am getting rendered html as
test content
It replaces the entire content of the html file. How to resolve this problem?
Kindly help.
Thanks,
John
Try this:
<script type="text/javascript">
function TestScript(){
return '<b>test content</b>';
};
</script>
Here is source code of the simple page:
<html>
<head>
<title>Test</title>
<script src="jquery-1.4.2.js" type=text/javascript></script>
</head>
<body>
<div id="divText">Original</div>
<script type="text/javascript">
var vText = document.getElementById('divText');
vText.innerText = 'Changed';
alert(vText.innerHTML);
$('divText').text = 'Changed with jQuery';
alert(vText.innerHTML);
</script>
</body>
</html>
"jquery-1.4.2.js" file is in the same folder.
Both alerts display "original" text, text in browser also "Original"...
What is wrong with my code? Any thoughts are welcome.
1. A quick google ( took me 2 seconds ) reveals text is a function, not a property. Use it like .text('lol') as the example directly from the API.
http://api.jquery.com/text/
2. innerText isn't available in every browser/DOM property.
As you pointed out in the title you'll be wanting to change the inner html. You'll also need the $('#divText') selector to get to the div with jQuery.
<html>
<head>
<title>Test</title>
<script src="jquery-1.4.2.js" type=text/javascript></script>
</head>
<body>
<div id="divText">Original</div>
<script type="text/javascript">
var vText = document.getElementById('divText');
vText.innerHTML = 'Changed';
alert(vText.innerHTML);
alert($('#divText'));
$('#divText').html('Changed with jQuery');
alert(vText.innerHTML);
</script>
</body>
</html>
so I have a few links that have a class of 'button', and I am trying to get their text values with the jQuery .text() function, but it is returning nothing at the moment,
code:
$(document).ready(function() {
var tester = $('a.test').text();
alert(tester);
});
HTML:
<a class='test'>TEST</a>
any idea why this might not be working?
This code works, just try....
<html>
<head>
<script src="http://code.jquery.com/jquery-latest.min.js"></script>
</head>
<body>
<a class="test">Test</a>
<p></p>
<script>
var string = $("a.test").text();
alert(string);
</script>
</body>
</html>
