function Voices(){

talk.setVoice('Google UK English Male')
}
talk.speak("What's up")}
</script>

below is the output of talk.listVoices() :

Firstly my answer is not the full solution, but there are some simple SyntaxErrors in your example. Thats why it's not runable for me at all.
You are opening click( but didn't close it, for better clearance i reformatted your code and added the closing bracket.
A function normally get's called with brackets, so it should be Voices();
This is not necessary for every Browser, but normally an ending line in JavaScript get's an ;
$('#talks').click(
function(){
console.log('hi');
var talk= new p5.Speech();
talk.onLoad=Voices();
function Voices(){
talk.listVoices();
talk.setVoice('Google UK English Male');
}
talk.speak("What's up");
}
)
With that changes i get an console output like this:
VM43:3: hi
p5.speech.js:136 p5.Speech: voices not loaded yet!
p5.speech.js:89 p5.Speech: voices loaded!

Hi I have a problem that I can't quite solve. I'm a total noob with HTML/Javascript, so I'm not sure how to proceed. The instructions are in the code:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Q2</title>
<script type="text/javascript" src="342.js"></script>
<script type="text/javascript">
function swap() {
if (Math.random()>.5){
document.getElementById("c").style.display = 'none';
document.getElementById("f").src = "images/f.jpg";
} else {
document.getElementById("d").style.display = 'none';
document.getElementById("f").src = "images/f.jpg";
}
}
</script>
</head>
<body>
<p>Add code so that clicking the button changes either the src "c.jpg" or "d.jpg" to "f.jpg" The choice of which should be replaced
should be determined randomly.</p>
<img src="images/c.jpg" id="c"><br>
<img src="images/d.jpg" id="d">
<br><br>
<button type="button" onclick="swap()">OK</button>
</body>
</html>
The original problem had everything but the scripts. When I try this, I'm able to get the image c or d to disappear, but image f doesn't appear. I don't know how to get the image to show. getELementById won't work because I haven't made an id, but how do I do that without having image f showing? Any help is appreciated.
Seems you're missing html
Try add f html element for work:
<img src="images/f.jpg" id="f">
The p tag in the html is talking about c.jpg, d.jpg and e.jpg.
Its not talking about f.jpg, you may want to check that
with the assumption that it is e.jpg and not "f.jpb". And also assuming that you have e.jpg in your images folder. Below code will work fine (small modification in the script)
function swap() {
if (Math.random()>.5){
// document.getElementById("c").style.display = 'none';
document.getElementById("c").src = "images/e.jpg";
} else {
// document.getElementById("d").style.display = 'none';
document.getElementById("d").src = "images/e.jpg";
}
}
I've got a problem when I want to go back with window.location.back() after using window.print().
When I click on my Print button, I'm redirected to a new page with the document to print and the print pop-in appear. On Chrome and IE, when we click on print into the pop-in, window.location.back() is triggered but not in Firefox ...
timeout(function () {
window.print()
window.history.back();
}, 500);
I've tried some possible solution like window.onafterprint or window.onbeforeprint events,
window.location.go(-1), but none works on Firefox.
Also, if I remove the window.print() line, window.location.back() works fine.
I've got no other solutions, could you help me ?
Are you sure you don't mean setTimeout?
Using Firefox, with the following html code:
<!DOCTYPE html>
<html>
<head>
<script>
setTimeout(function(){
window.print();
window.history.back();
}, 500);
</script>
</head>
<body>
<pre>Nothing here</pre>
</body>
</html>
seem to work just fine.
500ms after loading, the print dialog shows, then, it goes back in history.
I wrote the following HTML file:
<!DOCTYPE html>
<html lang="en">
<head>
<title>HTML page</title>
</head>
<body>
<script src='http://localhost:3000?callback=mycallbackFunction'> </script>
<script>
function mycallbackFunction(data) {
alert('here');
alert (data['a']);
}
</script>
</body>
</html>
As you can see, the script tag includes a JSONP request to a remote server.
In addition, I wrote the following node.js file and ran it as a server:
var express = require('express');
var app = express();
app.get('/', function(req, res) {
res.jsonp({'a': 'blabla'});
});
app.listen(3000);
After I had run the node.js file and opened the browser with the html page, I expected to see a pop-up window of alert. But, no. I didn't see anything.
The Network Tab in Developer Tools shows that the request has been accepted:
Do you know how to resolve it?
You need to swap the order of your <script> elements.
Explanation:
Express is correctly serving a script that looks like myCallbackFunction({'a': 'blabla'}), which is exactly what you hoped for. However, this script runs immediately, and myCallbackFunction has yet to be defined, so nothing happens. Then, in the next <script> block, you define myCallbackFunction, but this is useless, since the (failed) call has already happened in the previous <script>.
Also, you have a case mismatch on the C in mycallbackFunction -- make sure the capitalization agrees between the callback parameter and the name of your function.
The solution is to switch the order of both script tags:
<body>
<script>
function mycallbackFunction(data) {
alert('here');
alert (data['a']);
}
</script>
<script src='http://localhost:3000?callback=mycallbackFunction'> </script>
</body>
HTML code :
<html>
<head>
</head>
<body>
<script type="text/javascript" src="/js/colorbook.js"></script>
<script type="text/javascript">
book.init();
</script>
</body>
</html>
JS code :
var book = (function(){
init = function(){
console.log ( "initialized")
}return init();
}());
Question : The above code works. But I am unable to understand how?. Can any of JS guys help me here or guide me how should I start debug this code to understand it.
Ok so as per your comment. The Javascript you have there is all executed sequentially as the browser reads it from the incoming data stream. That being said, All javascript contained within the first script tag will be executed. Then the second script tag will be executed in sequence as well.
So right now you can look at the book.init() as being the last provided javascript call to be executed.
I tried your JS code in jsfiddle and could not get it to work check This Fiddle to see what I mean.
What is happening in your JS code is the last () at the end of the var book declaration executes the anonymous function which will print the line to the console. However from the code you supplied the book variable never gets a book.init() method. So once that call is reached it will throw an error of undefined.
My html document looks like this:
<html>
<head> .. load jquery and other stuff </head>
<body>
<div id="cool_container">
<div class="cool">.. no script friendly markup ..</div>
</div>
<a id="cool_link">Link</a>
<script>
function installStuff(){
$('.cool').coolPlugin();
$('#cool_link').click(function(){
$('#cool_container').load('/anothercooldiv.html');
});
}
$(document).load(function(){ installStuff(); });
</script>
</body>
</html>
Of course, /anothercooldiv.html gives another <div class="cool"> .. etc ...</div> fragment.
So what's the best way to turn the fresh cool div into a coolPlugin without breaking everything (and writing some nasty hacks) ?
It'd would be great to be able to either:
Call installStuff with a default jQuery context '#cool_container', so I could call something like:
$.doThisInContext(function(){installStuff();}, $('#cool_container');
In the load callback.
Or, have an equivalent of 'live' (that would solve the problem of links if cool contains links), but on an element existence, that I could use like that in my function installStuff:
$('.cool').exists(function(what){ what.coolPlugin() };
Then the coolPlugin would be installed on all cool elements now and in the future.
I'd suggest the .livequery() plugin for this still:
$(function() {
$('.cool').livequery(function() {
$(this).coolPlugin();
});
$('#cool_link').click(function(){
$('#cool_container').load('/anothercooldiv.html');
});
});
The important bit:
$('.cool').livequery(function() {
$(this).coolPlugin();
});
Will run for every current and future .cool element as they're added, running the plugin on each.
Applying the plugin to the newly ajax loaded content shouldn't be too tricky:
$('#cool_container').load('/anothercooldiv.html', function() {
$(this).coolPlugin();
});
