Sometimes when render reCAPTCHA widget, it will report an error Failed to load resource: net::ERR_BLOCKED_BY_RESPONSE from https://www.google.com/recaptcha/enterprise/anchor when load https://www.google.com/recaptcha/enterprise/webworker.js
image
And we can reproduce this by refresh the page again and again (use document demo code):
<html>
<head>
<title>reCAPTCHA demo: Explicit render after an onload callback</title>
<script type="text/javascript">
var onloadCallback = function() {
grecaptcha.enterprise.render('html_element', {
'sitekey' : ' site_key',
});
};
</script>
</head>
<body>
<form action="?" method="POST">
<div id="html_element"></div>
<br>
<input type="submit" value="Submit">
</form>
<script src="https://www.google.com/recaptcha/enterprise.js?onload=onloadCallback&render=explicit"
async defer>
</script>
</body>

I am trying to add math formula in ckeditor, from editor should collect entire information(including formula) display on the same page in different div.
When I do with the following approach it is displaying math formula as text(not formatting as formula).
<html>
<head>
<script src="https://cdn.ckeditor.com/4.8.0/full-all/ckeditor.js"></script>
<script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/mathjax/2.7.0/MathJax.js?config=TeX-AMS_HTML"></script>
<script>
function onSubmit(){
var data = CKEDITOR.instances.editor1.getData()
document.getElementById("show").innerHTML=data
}
</script>
</head>
<body>
<form action="#" >
<textarea rows="20" cols="70" class="ckeditor" id="editor1" name="test1">
</textarea>
<input type="button" value="save" onclick="onSubmit()" >
</form>
<div id="show" id='ed2'></div>
<script>
CKEDITOR.replace( 'editor1', {
extraPlugins: 'mathjax',
mathJaxLib: 'https://cdnjs.cloudflare.com/ajax/libs/mathjax/2.7.0/MathJax.js?config=TeX-AMS_HTML',
height: 320
} );
if ( CKEDITOR.env.ie && CKEDITOR.env.version == 8 ) {
document.getElementById( 'ie8-warning' ).className = 'tip alert';
}
</script>
</body>
</html>
It is faster and easier to use Katex rather than Mathjax for math formula rendering in Html.
For reference(Comparison between katex and latex ) :
https://www.intmath.com/cg5/katex-mathjax-comparison.php
So the solution by using katex will be :
<!DOCTYPE html>

<form action="#">

</textarea>
<input type="button" value="save" onclick="onSubmit()">
</form>
<div id="show" id='ed2'></div>
<script>
CKEDITOR.replace('editor1', {

Good luck !!!
So, here's some background: I am working on a MEAN stack app for my school where we can read and post our Galaga and Dig Dig highscores to a mongo database.
I am getting an error:
POST http://url.com/api/scores 500 (Internal Server Error)
TypeError: Cannot read property 'userName' of undefined at /app/server.js:37:22
server.js:37 is:
app.post("/api/scores", function(req, res){
Score.create({
name:res.body.userName,
game:res.body.game,
points:res.body.userPoints
});
});
The index.html that the res.body.* is coming from is:
<!DOCTYPE html>
<html ng-app="nameOfApp">
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1">

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.3/jquery.min.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.3.10/angular.min.js"></script>
<script src="core.js"></script>
</head>
<body ng-controller="mainController">
<div class="container">
<div class="jumbotron text-center">
<div class="container">

</div>
</div>
<div class="container">
<table>
<tr>
<td><b>Name</b></td>
<td><b>Score</b></td>
</tr>
<tr ng-repeat="score in scores">
<td>{{score.name}}</td>
<td>{{score.points}}</td>
</tr>
</table>
</div>
<br/>
<h2>Score?</h2>
<form>
<input name="userName" type="String" class="form-control" id="userName" ng-model="formData.userName" placeholder="Your Name">
<input name="game" type="String" class="form-control" id="game" ng-model="formData.game" placeholder="The game?">
<input name="userPoint" type="Number" class="form-control" id="userPoint" ng-model="formData.userPoint" placeholder="Points?">
<button type="submit" class="btn btn-default" ng-click="createScore()">Submit</button>
</form>
</div>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.3/jquery.min.js">
</script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.2/js/bootstrap.min.js">
</script>
</body>
</html>
and the core.js, which is the angular piece is:
var nameOfApp= angular.module('nameOfApp', []);
nameOfApp.controller("mainController", ["$scope", "$http", function($scope, $http) {
$scope.formData = {};
// when landing on the page, get all scores and show them
$http.get('/api/scores')
.success(function(data) {
$scope.scores = data;
console.log(data);
})
.error(function(data) {
console.log('Error: ' + data);
});
$scope.createScore = function() {
$http.post('/api/scores', $scope.formData)
.success(function(data) {
$scope.formData = {};
$scope.scores = data;
console.log(data);
})
.error(function(data) {
console.log('Error: ' + data);
});
};
}]);
Thanks for your input, and if there are any stylistic things that I have wrong, I would love to hear them. I am trying to get better at MEAN stack development.
It's not res.body.* you want to use in your Score.create method, you want to be using req.body.*. 'req' is what has all the data from your http request.
Should be:
app.post("/api/scores", function(req, res){
Score.create({
name:req.body.userName,
game:req.body.game,
points:req.body.userPoints
});
});
I am using ajax to auto refresh a div tag using this code in my index.php file:
<script type="text/javascript">
$(document).ready(function() {
$.ajaxSetup({ cache: false });
setInterval(function() {
$('#messanges').load('messanges.php');
}, 1000);
});
</script>
<div id="messanges"></div>
<textarea name="chat_input" id="chat_input"></textarea>
In messanges.php I have a auto scroll down code.
Cause I want it to start at the bottom when entering the chat.
<head>
<script>
var chat_height = $('#chat').outerHeight();
$('#chat_box').scrollTop(chat_height);
</script>
</head>
<div id="chat_box" style="height:700px; overflow:auto">
<div id="chat">
<div id="Name">Test user:</div>
<div id="img"><img src="picture.png" /></img></div>
<p class="triangle-isosceles left">
"Test" </p>
</div>
The code is now forcing the scroll to stay at the bottom because of the ajax auto refresh.
How can I make it auto refresh, but if I want to scroll up it will not force me down when it refresh?
try some like this
<head>
<script>
var chat_height = $('#chat').outerHeight();
if($('.doScroll').is(':checked'))
{
$('#chat_box').scrollTop(chat_height);
}
</script>
</head>
<input type="checkbox" class="doScroll" checked />
<div id="chat_box" style="height:700px; overflow:auto">
<div id="chat">
<div id="Name">Test user:</div>
<div id="img"><img src="picture.png" /></img></div>
<p class="triangle-isosceles left">"Test" </p>
</div>
I am diving in the deep end of this magic world of HTML. I have the CKEditor woring and myFunction produces the alert. I need to get the HTML of the text in the editor.
I got this from another post:
CKEDITOR.instances.textarea.on( 'instanceReady', function( instanceReadyEventObj )
{
var editorInstanceData = CKEDITOR.instances.textarea.getData();
alert( editorInstanceData );
});
I could not comment or reply to the post as I don't have enough points so I have to ask a duplicate.
I have the alert working and pasted the code in myFunction but I get the error in the console Uncaught TypeError: Cannot call method 'on' of undefined.
<!DOCTYPE html>
<html>
<head>
<script>
function myFunction()
{
var htmldata = CKEDITOR.instances.Editor.document.getBody().getHtml();
alert(htmldata);
}
</script>

I've tried moving into different place but I still get the same error.

MrWarby.
Before your SCRIPT in HEAD add two more lines:
<script type="text/javaScript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.1/jquery.min.js"></script>
<script src="/ckeditor/ckeditor.js"></script>
But change path to CkEditor script.
I tried to write an AJAX-type form with Twitter Bootstrap, but the updated div element disappears. Can I fix that?
<!DOCTYPE html>
<html>
<head><link href="bootstrap.min.css" rel="stylesheet" media="screen"></head>
<script>
function wordCloud(){document.getElementById("cloud").innerHTML = "WordCloud";}
</script>
<body>
<script src="http://code.jquery.com/jquery-latest.js"></script>
<script src="bootstrap.min.js"></script>
<div id="cloud"></div>
<form onsubmit="wordCloud()">
<fieldset>
<button type="submit" class="btn">Submit</button>
</fieldset>
</form></body>
</html>
Change as follows.
function wordCloud(){document.getElementById("cloud").innerHTML = "WordCloud";}
replace
function wordCloud(){document.getElementById("cloud").innerHTML = "WordCloud"; return false; }
and
<form onsubmit="wordCloud()">
replace
<form onsubmit="return wordCloud()">
