Now what i need guidance for was , i need the Parse button from parser.html to apply the functions for source.html and save as output.html in same path of source.html...
Kindly help me out ...
What Willshaw said is correct. Javascript don't have that much power to solve your problem. You need to go for some serverside scripting.
I agree with the previous answer, it is a pretty strange way to do.
But, the DOM parsing being really easy with javascript, you could do the parsing on the client side, I guess, and then send the processed html to your backend, and save it in result.html.
I will use Jquery for the example, way easier.
Parser.html
<!doctype html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>load demo</title>
<style>
<script src="//code.jquery.com/jquery-1.10.2.js"></script>
</head>
<body>
<button id="btnLoad">Load Source</button>
<button id="btnParse">Parse</button>
<button id="btnSave">Save</button>
<div style="display:none" id="sourceContainer"></div>
<script>
$(document).ready( function() {
$(".btnLoad").click(function(){$("#sourceContainer").load("/source.html");})
$(".btnParse").click(function(){
$(".sourceContainer h1").removeAttr("style");
$(".sourceContainer p").removeAttr("style");
})
$(".btnSave").click(function(){
var data = {
html: $("#sourceContainer").html()
};
//replace first param by the backend url, add callback function
$.post("http://...", data, ...);
})
});
</script>
</body>
</html>

I would like to add forms to a page in real time, but I'm not sure how to approach this.
Let's say that this is the class of my form:
class MyForm(FlaskForm):
my_field = StringField()
This is the html
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
<button type="button" id="addNewForm">Add new form</button>
</body>
</html>
Which also includes this script:
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.5/jquery.min.js">/script>
<script type="text/javascript">
var form = '{{ form }}'
$("document").ready(function () {
$("#addNewForm").click(function () {
$("body").append(form)
});
});
</script>
Once I press the button I get back something like:
<forms.MyForm object at 0x000001C198CE5040>
I tried to extract the form HTML in order to pass it as an a string of html, but I can't find a way to do it (and suspect that there must be a better way).
What is the correct way of doing this?
I am looking to create a website that compiles the HTML code that you write it in a text editor.
Here is my code:
<!DOCTYPE html>
<html>
<head><title>HTML editor</title></head>
<body>
<textarea id="textarea">
</textarea>
<iframe id="frame" srcdoc="This is where the code is interpreted. ">
</iframe>
<button onclick="run();"></button>
<script>
function run() {
var x = document.getElementById("textarea").value;
var y = document.getElementById("frame");
y.srcdoc = x;
}
</script>
</body>
</html>
Write now, I have successfully created something that compiles html code. But I want to do the syntax highliting. How do I highlight the text?
Just add the required CSS and JS for Prism.js.
<!DOCTYPE html>
<html>
<head>
...
<link href="https://myCDN.com/prism#v1.x/themes/prism.css" rel="stylesheet" />
</head>
<body>
...
<script src="https://myCDN.com/prism#v1.x/components/prism-core.min.js"></script>
<script src="https://myCDN.com/prism#v1.x/plugins/autoloader/prism-autoloader.min.js"></script>
</body>
</html>
Then add below HTML element
<pre><code class="language-css">p { color: red }</code></pre>
whatever code you write in this element will have syntax highlighting. class="language-css" determines the language for hightlighting, you can change as per your requirement. You can find all supported languages here.
Note: this is a basic example you can start from here and find more info at prism.js usage
I want to get the data from the another html file using angularjs $http get method, but i did't get anything

I created a web page wherein I want to display there another HTML file. I used jQuery to do this but wasn't able to display the content of the file I have included. Why do you think this happened. Thanks a lot.
Here's my code for my mainpage.
sample.html
<html>
<head>
<title> Sample Only </title>
<script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.1.0/jquery.js"></script>
<script>
$(function(){
$('#footerLang').load("sampleFooter.html");
});
</script>
</head>
<body>
<div id="footerLang">
<h1></h1>
</div>
</body>
</html>
sampleFooter.html
<p> THIS IS A FOOTER </p>
It is highly possibly because you are placing the following block in head without $(document).on("ready", function() { ...; });
$(function(){
$('#footerLang').load("sampleFooter.html");
});
In this case jQuery will unable to find the #footerLang element since the DOM is not ready, you could revise the script as follow
$(function(){
$(document).on("ready", function () {
$('#footerLang').load("sampleFooter.html");
});
});
or move the script tag just before the </body>
<html>
<head>
<title> Sample Only </title>
<script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.1.0/jquery.js"></script>
</head>
<body>
<div id="footerLang">
<h1></h1>
</div>
<script>
$(function(){
$('#footerLang').load("sampleFooter.html");
});
</script>
</body>
</html>
I found out that this was just a browser compatibility issue. I launch it in Firefox and it worked.
I am trying to develop a simple back-end widget for asp. Since, I am new to ASP, I chose JavaScript as ASP language. I think I don't have the right tool to write to output. Response.Write() sends output directly to the start of the page. What I am missing here?
Hers is the code that I made:
<!DOCTYPE html>
<html>
<body>
<h2>Hello world</h2>
<script language=Javascript runat=server>
Response.Write("Hello JS");
</script>
</body>
</html>
which is giving the following output:
Hello JS <!DOCTYPE html>
<html>
<body>
<h2>Hello world</h2>
</body>
</html>
There is a great answer on the subject here but basically if you want this to work change the above code block as follows;
<!DOCTYPE html>
<html>
<body>
<h2>Hello world</h2>
<% Call Response.Write("Hello JS"); %>
</body>
</html>
You can also replace the above line of code with <%= "Hello JS" %> as a shortened form of Response.Write() method.
if you want to use javascript then it should be like this:
<script language=Javascript>
alert("Hello JS");
</script>
or
<script language=Javascript>
alert('<%=SomeVarfromASP%>');
</script>
Those will give you POP up boxes with your message or in your case value of your variable in it.
Basically when you put "<%=" it is pretty much like you say please write this...
If you need something to be typed/printed on the page by JavaScript you will need to use more specialized functionality such as getelementbyid or similar.
Your code would look like:
<html>
<head>
<script type="text/javascript">
function ChangeGreet()
{
var vgreet = document.getElementById("JSGreet");
vgreet.innerHTML = 'Hello JS';
}
</script>
</head>
<body onload="ChangeGreet()">
<div>Hello MS</div>
<div id="JSGreet"> </div>
</body>
</html>
JavaScript and VBScript(Classic ASP) have their own syntax. Look it up at http://www.w3schools.com/js/DEFAULT.asp. It has great tutorials for beginners in both languages.
