I'm encountering a problem where my body onload="constructor()" is not being run. It works fine for me in firefox but I don't understand why it's not working for me in chrome. Here's the code I'm working with, I made a separate file and deleted everything to the bare minium to try figure out what was going wrong:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8" />
<title>Personality Font</title>
<link rel="stylesheet" type="text/css" href="p1.css" />
<script type="text/javascript" src="data.js"></script>
<script type="text/javascript">
//<![CDATA[
function constructor(which)
{
console.log("IN CONSTRUCTOR"); //In Constructor
var text = document.createElement('p');
text.appendChild(document.createTextNode("BLAH"));
document.getElementsByTagName('body')[0].appendChild(text);
}
//]]>
</script>
</head>
<body onload = "constructor();">
<h1>Personal Fonts: Find the Typeface that Matches Your Personality</h1>
<form>
</form>
</body>
</html>
Chrome has a built-in function with the name constructor. Call the function something else.

I'm learning to use event listeners, I wanted to log pressing the "Start" button to the console to make sure the button works but I'm not getting any results when I test the .html file in devtools.
I've verified the index.js name referenced in the .html file is the same
I've tried the source code in the header
I've added the src=index.js jQuery library through Google to the bottom before </body>
I've copied the code to repl.it to try a different environment
JAVASCRIPT:
function startQuiz() {
$('#startButton').click(function(event){
console.log("Keep Going");
});
}
HTML:
<html lang="en">

<link href="style.css" rel="stylesheet" type="text/css" />

<div class="container">

I expect the to see "Keep Going" in the console when I press "start" but instead nothing happens at all.
You have the JQuery click() function inside the startQuiz() function. So it won't work unless the outer function (startQuiz()) is run first. You should put it inside a ready function so that it loads once the page is 'ready'.
Change your javascript to look like this:
$(document).ready(function() {
$('#startButton').click(function(event) {
console.log("Keep Going");
});
});
No need to go with jQuery , you can just use js events.
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width">
<title>Log Window</title>
</head>
<body>
<script>
function logMe() {console.log('clicked');}
</script>
<button onclick="logMe()">logMe</button>
</body>
</html>
You should put it inside a Jquery click function. This way it will fire when the document loads.
$(document).ready(function() {
$('#startButton').click(function(event) {
console.log("Keep Going");
}
});
I am trying to learn about p5 and have been going through the tutorials (https://p5js.org/reference/#/p5.SoundFile).
function preload() {
soundFormats('mp3', 'ogg');
mySound = loadSound('assets/cam.mp3');
}
function setup() {
mySound.setVolume(0.1);
mySound.play();
}
I have followed the documentation verbatim, except for the fact that I switched in my own test song. When I run this on my repl.it https://repl.it/#JacksonEnnis/Coloquial I get an error stating "ReferenceError: soundFormats is not defined". However, I know that this function IS defined, because it is from the documentation. I have googled the problem, but it does not seem like it is a common issue to experience.
If anyone understands why this is happening, please explain it to me so I may learn.
HTML:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width">
<title>repl.it</title>
<link href="style.css" rel="stylesheet" type="text/css" />
</head>
<body>
<script language="javascript" type="text/javascript" src="path/to/p5.sound.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/p5.js/0.9.0/p5.js"></script>
<script src="script.js"></script>
</body>
</html>
Just to sum up the comments.
Here's the solution that works:
<!doctype HTML>
<html>
<head>
<html><head>
<script src="https://cdnjs.cloudflare.com/ajax/libs/p5.js/0.5.16/p5.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/p5.js/0.5.16/addons/p5.sound.js"></script>
</head>
<body>
<script>
function preload() {
soundFormats('ogg', 'mp3');
mySound = loadSound('https://ia802508.us.archive.org/5/items/testmp3testfile/mpthreetest.mp3');
}
function setup() {
mySound.setVolume(1);
// mySound.play();
mySound.loop();
}
</script>
</body>
</html>
as you can see: the p5.sound.js file has to be included as well. It has to be a valid path and it has to be loaded after the p5.js.
soundFormats is a function defined in p5.sound.js. And if this javascript file has not been loaded properly, an error message "soundFormats is not defined" comes up.
I've had a look at similar answers but haven't seen an answer to this.
My directory structure is simply:
Test
|---index.html
|---bootstrap.min.css
|---angular.min.js
|---app.js
My code:
<!doctype HTML>
<html ng-app="store">
<head>
<title>Test</title>
<link rel="stylesheet" type="text/css" href="bootstrap.min.css">
</head>
<body>
<script type="text/javascript" src="angular.min.js"></script>
<script type="text/javascript" src="app.js"></script>
<p>I am {{4 + 6}}</p>
<p>{{"Hello" + " you"}}</p>
</body>
</html>
Sadly, running this in the browser (file:///Users/Will/Projects/angular/demo/index.html), it doesn't work. Is this because it's local?
Consider that the following works when loaded directly from the filesystem (and not a webserver):
<!doctype HTML>
<html ng-app>
<head>
<title>Test</title>
</head>
<body>
<script type="text/javascript" src="angular.min.js"></script>
<p>I am {{4 + 6}}</p>
<p>{{"Hello" + " you"}}</p>
</body>
</html>
Note that I have changed "ng-app='store'" to "ng-app", so that angular is not trying to load the 'store' module.
This shows that angular, on its own, is doing its thing correctly. So the issue is somewhere within the store module. As suggested in the comments, check your browser console for error messages, and troubleshoot those.
I am trying the following to write the contents of a local text file (version.txt) to the screen, but it isn't working.
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<link rel="stylesheet" type="text/css" href="css/index.css" />
<script charset="utf-8" src = "jquery-1.10.1.min.js"></script>
<script charset="utf-8" src = "cordova-2.7.0.js"></script>
<script>
function test()
{
$.get("version.txt", function(data) {
document.write(data);
});
}
</script>
<body>
<button type="button" onclick="test()">Print version.txt</button>
</body>
</html>
Any idea what I'm doing wrong?
update: this works, I was just mistyping the name of the jquery file I was including.
You're missing a closing brace. The console will clearly tell you about invalid Javascript if you look.
You can't use document.write after the page has loaded. (Well you can, but you won't get the result you want.) Use jQuery append() instead.
I don't know wheater it is typo or not you are missing closing brace for function test
<script>
function test()
{
$.get("version.txt", function(data) {
document.write(data);
});
}
</script>
Just made a basic program to fin the root of my problem and I can't seem to find why this is not working at all.
HTML
<html lang="en">
<head>
<script type="text/javascript" src="carjava.js"></script>
</head>
<body onload="hi()">
hi
</body>
</html>
JS
function hi() {
alert("hi");
}
I want an alert to pop up when the page loads but nothing happens, any ideas?
I can't tell you why it isn't firing, but this should work:
HTML
<html lang="en">
<head>
<script type="text/javascript" src="carjava.js"></script>
</head>
<body>
hi
</body>
</html>
JS
function hi() {
alert("hi");
}
window.onload = hi;
following code is working fine for me:
<html lang="en">
<head>
<script type="text/javascript" src="carjava.js"></script>
<script type="text/javascript">
function hi()
{
alert('hi');
}
</script>
</head>
<body onload="hi()">
hi
</body>
</html>
Its working fine in Firefox & Chrome. Must be something with js file.
