Java Script: Using a Toggle to Show More or Less - javascript

I need some help. I have to write a javascript code that will toggle the a element for show more or less. If I click on show more, it should show the more with a link for show less.
Problem I am Having
1. If I click show more About the Author, instead of just showing more info about just that, it will also show more info about the book description, and who this book is for.. I don't want it to do that, I just want it to show me more info about just that specific one.
2. It's also not showing me or giving me the less link option.
Here is my HTML and JavaScript code.
$(document).ready(function() {
$("#jdom").click(function() {
$("a").toggle(function () {
$(this).text("").siblings("div").hide();
}, function() {
$(this).text("Less").siblings("div").show();
});
});
});

I don't know what I am doing wrong.

Try This,
$(document).ready(function() {
$(document).on('click','a',function(e){
$(this).text( ($(this).text() == "Show more") ? "Less":"Show more" ) ;
$(document).find($(this).attr('data-target')).toggle();
/*OR WITH ANIMATION*/
/*
if($(this).text() == "Show more"){
$(this).text("Less");
$(document).find($(this).attr('data-target')).slideDown(300);
}else{
$(this).text("Show more");
$(document).find($(this).attr('data-target')).slideUp(300);
}*/
});
/*MORE ACTION*//*
$(document).on('click','#jdom',function(e){
$(document).find('a').each(function(){
$(this).trigger('click');
})
});
*/
});

I have modified the HTML a bit, and JS as well. Try using like this, it might give you solution.
$(document).ready(function() {
$("a").click(function(e) {
e.preventDefault();
var moreSection = $(this).parents(".section").find(".more-section");
if($(this).text() == "Show more" && moreSection.hasClass("hide")){
$(this).text("Show less");
moreSection.removeClass("hide").addClass("show");
}else{
$(this).text("Show more")
moreSection.addClass("hide").removeClass("show");
}

It is working fine in Chrome Ver 46.0 but not in IE11.

Why on('click', function ()) isn't working in jQuery? [closed]

Closed. This question needs debugging details. It is not currently accepting answers.
Edit the question to include desired behavior, a specific problem or error, and the shortest code necessary to reproduce the problem. This will help others answer the question.
Closed 8 years ago.
Improve this question
I have a very simple website with some menu tabs (i.e. Home, About Me etc.) and few paragraphs. I added click function inside my .JS file so that the clicking on tab can navigate to the desired paragraph (or page). But it's not working.
I should refernce to this post as I posted back.
[NOTE: I have apache running in my computer and xwamp is installed. I have jquery source added into my file and they are accurately saved in correct path or file. Besides I have Bootstrap installed, though I didn't necessarily need to set path for any file to it.]

You're including (and thus executing) the JavaScript before the elements exist on the page. HTML/JavaScript is processed in the order in which is exists in the DOM. So when this runs:
$("li")
the parser is only at the top of the HTML body and hasn't loaded any li elements into the DOM yet. Thus, that selector doesn't find anything.
Either put the JavaScript at the end of the DOM or wrap it in a document ready handler:
$(function () {
$("li").on('click', function () {
// etc.
});
});
(or both)
on not support from jquery 1.9, try live
$("li").live("click",function(){});
I looked at your code and was wondering if replacing
$("li").on('click', function () {
with
$("li").click(function() {
would solve the issue. I've used jquery for a while but have never used ".on" but my onclicks work fine. Hope this helps!

page.onload function not running

I just started making my first website, and this is the first REAL problem that I have run into. I'm trying to make "Sign in" and "Sign up" buttons that automatically change their text if the user is logged in. To do it, I'm using Javascript to read the localStorage username value, check if it equals null, and then set both button's .innerHTML based on that. The problem? My Javascript won't run. Here's the HTML/Javascript code:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>Phyre-Home</title>
<link href="Phyre-Home.css" rel="stylesheet">
<script language="javascript">
page.onload function{
var profile = document.getElementById("Profile");
var signout = document.getElementById("SignUpOut");
var username = localStorage.getItem('phyreUsername');
if(username == null) {
profile.innerHTML = "Sign in";
signout.innerHTML = "Sign up";
}else{
profile.innerHTML = username;
signout.innerHTML = "Sign out";
}
}
</script>
</head>
<body>
<header>
<img src="PhyreSiteHeader.bmp" alt="Phyre">
<button id="SignUpOut"></button>
<button id="Profile"></button>
<h1 style="display:none">Fire</h1>
<script language="javascript">
</script>
</header>
<nav>
<ul>
<li><b>Home</b></li>
<li>Profile</li>
<li>Games</li>
<li>Chat</li>
<li>Videos</li>
</ul>
</nav>
<aside>
<h1><b>Page Nav</b><br></h1>
<p><i>This page does not have its own, separate navigation section. Sorry.</i></p>
<h1><b>Ads</b><br></h1>
</aside>
<article>
</article>
</body>

The culprit is the first Javascript section. Please help if you can, I'm pretty new to HTML5, CSS3, and Javascript.
P.S. I don't have a domain or anything yet, so none of the links are valid.
As far as I know, there's no such thing as page, you probably want window
window.onload = function() {...
or just drop the onload handler and move the script to the bottom, right before </body>
The main issue is that page is not a JavaScript variable.
You could do something like
function myLoadFunction() {
...
}
then
<body onload="myLoadFunction()">
...
</body>
Alternatively you can use window.onload
window.onload = function () {
...
};
I have made you a completely working example here, that does everything you are asking, you may simply click this link to see it in action. You may click the second link in order to see the code and dissect it a bit.
Working Sample (with username)
Just click the link to see it work.
Working Sample (without username)
Just click the link to see it work.
Working Sample (Code)
Just click the link, then click Run with JS to see it work.
Now that I have shown you a completely working solution, allow me to explain why it works.
You do not appear to be using any sort of external library, this means that there is really nothing running overhead to try and help manage when these events fire and such.
You did not declare any kind of id on the elements you were trying to fetch
To demonstrate this, I cite your original code;
var profile = document.getElementById("Profile");
Which was assumed to be functioning on the following <a> tag.
<li>Profile</li>
The problem here is that document.getElementById actually needs an id to get by. This is remedied by ammending the <a> tag with an id, like this.
<li><a id="Profile" href="www.phyregaming.com/profile">Profile</a></li>
The next part of the problem is that you needed this code to run only after the page had loaded. But because you're running just normal javascript, it will run in the order it is seen - unless wrapped inside of a function. Because page.onload is not a valid function, your javascript simply threw an error, and since page.onload is not a real function, it didn't quite understand what its own problem was, so it didn't give you any really useful information.
I fixed this by first wrapping your code in a function, like this.
<script type="text/javascript">
function ready() {
// your javascript code here
}
</script>
What this meant is that when the page hit that part, it created the function, but it did not run it.
Then you needed to run the function, but only once the other parts of the page were ready. We did this using the onload attribute of the <body> tag, like this;
<body onload="ready()">
And that is really all there is to it! From there it was just a matter of assigning the id attributes where needed, and doing a little bit of housekeeping to the HTML and CSS.
I made some changes to help your sample run a bit better, most noticed is that I removed this part of your CSS
#Profile { position: absolute; top: 0%; right: 7.5em; }
I am not sure if you need it to be positioned like that, but from what it looked like, you wanted to make sure that the Profile section is also where the user finds the Login and Logout buttons. I accommodated by moving the <li> that contained those elements to the last ones in the list, this will ensure they are always rendered in the upper right part of the page, for this example.
The first one is just a sample showing how to run the code when the page is loaded. The second shows where you would put your actual code, but I do not know what your specific javascript is aiming to accomplish, so I commented it out.
Here is the complete working code.
You can remove the line localStorage.setItem("phyreUsername", "Ciel"); or comment it out, to see how the behavior changes based on whether or not a username is found.
HTML
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>JS Bin</title>
<script type="text/javascript">
function ready(){
// comment this line out to test different behaviors
localStorage.setItem("phyreUsername", "Ciel");
var username = localStorage.getItem("phyreUsername");
var profile = document.getElementById("SignIn");
var signout = document.getElementById("SignUpOut");
if (username == null) {
profile.innerHTML = "Sign in";
signout.innerHTML = "Sign up";
} else {
profile.innerHTML = username;
signout.innerHTML = "Sign out";
}
}
</script>
</head>
<body onload="ready()">

<ul>
<li><b>Home</b></li>
<li>Games</li>
<li>Chat</li>

I hope that this gives you enough information to really start making some headway. If you have further questions, please ask.

Creating a GWT widget that others can embed in their website?

I've created a widget in GWT and I would like to be able to give users a small snippet of HTML that they can embed in their website so my widget will be rendered there.
I don't believe an iframe would be appropriate as one requirement is that clicking any links on my widget should take the user to my website (not just change the content of the iframe).
Any help would be greatly appreciated.
P.S. I tried embedding the following, but no luck:
< script src="http://embeddedapptest.appspot.com/embeddedapp/embeddedapp.nocache.js" >< /script >
< div id="foo" / >
It is possible. The snippet will need to be like
<script src="yourmodule.nocache.js"></script>
<div id="foo"/>
Then in your entry point do this:
RootPanel root = RootPanel.get("foo");
// add your things here. root.add(...);
You will need to be careful not to step on the outer page's styling and vice versa but compiled CSS should go a long way to helping that.
This is the technique used to embed an APIs Explorer in Google APIs documentation.
I don't think it's possible to do it now. But in the future you can use Web Components to do that.
But there's the possibility to export a GWT/Java API using gwt-exporter. That makes it possible to automatically create a JavaScript API. gwtchismes uses this to export a JavaScript version of GWT widgets. You can find a tutorial about it in their wiki.
In NetBeans GWT project
mycss.css:
body, html,div.wrap-frame{
margin: 0;
padding: 0;
widht: 100%;
height: 100%;}body{
background: white;
}
.row1or3 {
width: 100%;
height: 10%;
background: blue;
text-align: center;
}
.row2{
width: 100%;
height: 80%;
background: yellow;
text-align: center;
display:flex;
}
.wrapper{
width:100%;
height: 100%;
}
.box{
float:left;
height: 100%;
}
.box:nth-child(1){
width:25%;
background-color:red;
}
.box:nth-child(2){
width:50%;
background-color:green;
}
.box:nth-child(3){
width:25%;
background-color:yellow;
}

MainEntryPoint.java
public class MainEntryPoint implements EntryPoint {
/**
* Creates a new instance of MainEntryPoint
*/
public MainEntryPoint() {
}
/**
* The entry point method, called automatically by loading a module that
* declares an implementing class as an entry-point
*/
public void onModuleLoad() {
final Label label = new Label("Hello, GWT!!!");
final Button button = new Button("Click me!");
button.addClickHandler(new ClickHandler() {
public void onClick(ClickEvent event) {
label.setVisible(!label.isVisible());
}
});
RootPanel root = RootPanel.get("mydiv");
root.add(button);
root.add(label);
}
}
Now you can name any div element of any html page as id=mydiv and add the compiled GWT jscript.
I have tested.
