I'm new to jQuery and jQuery mobile. I'm trying to understand how to execute a function when a button is clicked. I've tried the methods I've seen in tutorials, but it isn't working for me. Here's my code. I get the 'document is ready' alert, but don't get an alert when the button is clicked. I've also tried it with the .click() outside of the ready function. If anyone can find what I'm doing wrong, it will be greatly appreciated. Thanks in advance!

Remove the # from the id value in your a tag. # is a jQuery selecter which species its an ID. Change this line

Replace:

The id shouldn't have the "#".

I am currently working on the beginning stages of js and trying to create buttons and alerts with it. when i write my code, the alerts work but my buttons are not appearing. when i inspect my webpage, the buttons dont even appear in the code. any suggestions on what i can do to fix this?
alertmessage.html
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>alert message</title>
</head>
<body>
<p>Javascript.</p>
<script type="text/javascript" src="js/code.js">
</script>
</body>
</html>
code.js
window.alert("Welcome to Javascript");
buttons.html
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>alert message</title>
</head>
<body>
<p>Javascript.</p>
<button onclick="alert('How can I help you?')">Click me.</button>
<button id="button 2">Click me.</button>
<script>
document.getElementbyId("button 2").onclick=function(){
alert("You have just clicked me!");
}
</script>
</body>
</html>
well at first try not to use spaces when you create your buttons ids e.g (id="button 2")
instead use id="button2"
I modified your code adding the event listener on document ready find the below code hope that is what you are looking for, it should get your started.
Note: for posting here when you write your message paste your code under your message text and select the code then Press ctrl+K that should identify your code area then post it and all should work fine...
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>alert message</title>
</head>
<body>
<p>Javascript.</p>
<button onclick="alert('How can I help you?')">Click me.</button>
<button id="button2">Click me.</button>
<script>
$(document).ready(()=>{
document.getElementById("button2").addEventListener("click", function(){
alert("You have just clicked me!");
});
})
</script>
</body>
</html>
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">
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width">
<title>Herbal Medicine: Adaptogens</title>
<link href="style.css" rel="stylesheet" type="text/css" />
<link rel="questions" href="store.html">
</head>
<body>
<div class="container">
<p>Intro to Herbal Adaptogens explaining what they are</p>
<button id="startButton">Start</button>
</div>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.4.1/jquery.min.js"></script>
<script src="index.js"></script>
</body>
</html>
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");
}
});

Can anyone please suggest me regarding this issue ...
Since you're using jquery already I would say the easiest would set the jquery event click for the folders to select the text input element and use the .val () function to set your new value so it would look something like this
$(".folder selector").click (function (){
$(".textbox selector").val ("/"+this.text());
});
I'm not sure if the value function works on input elements but if not you could change it to a <textarea></textarea>
I'm really new at this and I would like to create collapsible menus using jQuery Mobile. I went over to their site and found this resource:
http://demos.jquerymobile.com/1.4.0/collapsible/
So, I made a test page:
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>Untitled Document</title>
<script src="scripts/jquery-1.11.3.js"></script>
<script src="scripts/jquery.mobile-1.4.0.min.js"></script>
</head>
<body>
<div id="div2014" data-role="collapsible">
<h3>2014</h3>
<p>
Q1<br/>
Q2<br/>
Q3<br/>
Q4
</p>
</div>
</body>
</html>
but I can't seem to get it to work. All that gets displayed is this:
Please help! I'm really new at this, so I'm not sure if I'm doing things right :(
You need to include the jquery.mobile CSS file as well.
<link rel="stylesheet" href="http://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.min.css" />
make use of jQuery's slideToggle() function on click.
See this pen and click 2014, the menu will be displayed and collapsed on clicking it again
Hi I have two html pages in my mobile application as follows:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
<title>jQuery Mobile: Demos and Documentation</title>

<body>
<div data-role="page" id="jqm-home" class="type-home">
<div data-role="content">
Index
</div>

</html>
my example.html is like:

<body>
<div data-role="page" id="jqm-home" class="type-home">

Test
</div>
<script type="text/javascript">
window.onbeforeunload = function(evt) {
console.log ("*****************");
}
</script>
</div>
</body>
</html>
Now suppose on click of Index button I goes to example.html page. on click of back button in example.html it again goes to index.html. everything is fine, but it does not print console.log ("********"); If i press one more back on index.html then it prints it, what I want is it should print that on click of back button when I am on example.html.
Whats wrong in above code? and why it behave like this? Any suggestion will be appreciated thanks in advance.
In Jquery Mobile standard use you basically stay on the same page during your hole experience on the site. "Changing" page basically adds content dynamically to the current document, meaning it will not trigger your onbeforeunload event.
You can however use jquery mobile events, which one depends on exactly what kind of action you want to take. Most probably you would be looking at pagebeforehide or pagehide
What you can do is add an event to the back button.
If you have a button :
<button id="backButton"> Go Back </button>
you can add via jquery following event
$("#backButton).click(function(){
console.log ("*****************");
});
Keep in mind, if you click a button, a post will happen and the page will be refreshed. So you should add the log function inthe document ready of the other page.
So if the example.html page loads, you just fire this event
$(function(){
//All code that starts when the page is fully loaded.
console.log ("*****************");
});
