so here is the thing i have a block of html code that needs to be replaced when a button is clicked. Its no big deal using
$('div.myCustomReplacer').replaceWith(newHTML);
but i also need to render a django-form {{ form }} in the new HTML
when i simply use
<div class="NewDiv"> {{ form }} </div? the html is rendered as "{{ form }}" because of those quotes the form is not rendered.
So how i do remove those ?
sorry just new to JavaScript.
I don't think you can achieve it like that. Remember that the form is added when html is rendered in the server, so basically {{form}} doesn't exist in client.
No worries, there are several simple ways to reach you goal just using simple JavaScript. One way is to simple let server inject the form, and just make it visible when user click button. Take a look at the example I made for you.
document.getElementById('showBtn')
.addEventListener('click', function () {
document.getElementById('targetDiv').style.display = 'block';
});
document.getElementById('hideBtn')
.addEventListener('click', function () {
document.getElementById('targetDiv').style.display = 'none';
});
html, body {
width: 100%;
height: 100%;
font-family: 'Roboto', sans-serif;
}
button {
margin: 1rem;
}
section {
margin: 1rem;
}
section span {
background-color: lightcoral;
font-size: small;
padding: .5rem;
}
<!doctype html>
<html lang="en">
<head>

I have created a simple addition program using HTML, CSS and Javascript.
HTML code is as follows:
<head>
<title>Input Output</title>
<link rel="stylesheet" type="text/css" href="io.css">
<body>
<h1>Sum App</h1>
<div class="container">
<script type="text/javascript" src="io.js"></script>
First Number <input type="text" id="numOne">
Second Number <input type="text" id="numTwo">
<button type="button" class="btn" onclick="submitBut()">Submit</button>
<p id="result"></p>
<div class="screen" id="screen1"></div>
</div >
The Javascript code is as follows:
function submitBut(){
var numOne= document.getElementById("numOne").value;
var numTwo= document.getElementById("numTwo").value;
var sum=parseInt(numOne)+parseInt(numTwo);
var element= document.createElement("p");
document.getElementById("result").innerHTML = sum;
}
I want to now style the result which as per the code seats in between paragraph tags with id "result".
What are the ways using which this is possible?
I tried using a standard style sheet format as below:
#result {
font-size: 45-px;
background-color= Yellow;
}
However, it is not working at all. Kindly let me know possible fixes.
Regards,
The problem is with the CSS you have written for this code. It's Invalid.
Change it like the following and it will work fine:
#result {
font-size: 45px;
background-color: yellow;
}
I'm try to load the page content via the JQuery load() method.
Here is the code
$(window).ready(function() {
$('#content').load('views/login.html');
});
.mdl-layout {
align-items: center;
justify-content: center;
}
.mdl-layout__content {
padding: 24px;
flex: none;
}
<link href="https://code.getmdl.io/1.3.0/material.indigo-blue.min.css" rel="stylesheet" />
<script src="https://code.getmdl.io/1.3.0/material.min.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="mdl-layout mdl-js-layout mdl-color--grey-100">
<main class="mdl-layout__content" id="content">
</main>
</div>
(Sorry but i can't add the login.html to the snippet editor. It's a login form powerd by the mdl framework:/)
Now the Javascript functions for the form element from mdl does not work correctly. There are no errors in the developer console. I've also tried to reload all my javascript files after the load request by jquery?
Does anyone have any idea what's going wrong with my script?
I've solved this problem by myself. Here the solution:
I simply call the mdl javascript after the load method again.
$.getScript('https://code.getmdl.io/1.3.0/material.indigo-blue.min.css');
Now it works perfectly. Thanks to all!
if code you provided is copied from your .html file then structure is not good.
Here is working version:
<!doctype html>
<html>
<head>
<meta charset="utf-8" />
</head>
<body>
<style>
.mdl-layout {
align-items: center;
justify-content: center;
}
.mdl-layout__content {
padding: 24px;
flex: none;
}
</style>
<link href="https://code.getmdl.io/1.3.0/material.indigo-blue.min.css" rel="stylesheet" />
<script src="https://code.getmdl.io/1.3.0/material.min.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="mdl-layout mdl-js-layout mdl-color--grey-100">
<main class="mdl-layout__content" id="content">
</main>
</div>
<script type="text/javascript">
$(window).ready(function() {
$('#content').load('views/login.html');
});
</script>
</body>
</html>
CSS styles needs to be enclosed with tags, and Javascript code must be closed within tags
Hope this helps you.
I m having following code to convert image using html2canvas. It is working fine but the select tag icon (down arrow) is not coming when capture the image

Image is capturing correctly but only the select icon is not coming properly.how to fix this issue ?
This is part of browsers default CSS, everything is not accessible to html2canvas, and it should not be (possible leak of privacy info on some OS).
Maybe this exact one could be tweaked for chrome, since chrome does expose some of its shadow selectors, but I don't even know if it is in the list, and anyway, since non-standards these selectors could change at any time in the future, and here is how it looks like on my FF :
So the best for you, is to create the dropdown entirely from scratch. This way all UAs will show the same, and html2canvas will be able to "snapshot" it.
I am trying to add a button to a simple webapp, however i do not know how to make it work. I am using Node,express,ejs. I have two major issues:
What i want to make happen is that when i click the button,it should redirect me to a different page '/applist' which has a list of all my applications.
I am trying to add an image, which doesn't show and just alt text appears.Image is in the same folder as shown. Image size is 679x1178 pixels.
There is an auto-generated app.js which of course has all required modules included.
The files below are ( index.js , style.css, index.ejs ) respectively.
var express = require('express');
var router = express.Router();
/* GET home page. */
router.get('/', function(req, res, next) {
res.render('index', {
title: 'Welcome to AJ homepage'
});
});
module.exports = router;

h1 {

Try using an <a href="/my_applications"> instead of the <button>, you should still be able to style it as a button. Check this answer out:
How to create an HTML button that acts like a link?
, as it shows other options, like using a <form>.
Also, in your express code you will need to define the route you want to serve.
I'm not sure why you need a button in this scenario. I suggest using an ordinary anchor link:
My applications
<a href="/applist"> you can this anchor tag instead of button . this will be redirect to your applist page where you have define the route.
I have looked up a question on the website (How to display javascript variables in a html page without document.write)
But when executing it in my own coding program it does not work. Hope you can help out!

Because you have syntax error.. check the console.
Correct code should be:
$jsName.addEventListener('input', function(event){
$jsValue.innerHTML = $jsName.value;
}, false);
