Copy and paste text from a div to another [jQuery] - javascript

I am trying to do a thing that seems easy to me but I'm not very familiar with javascript language and I can't find any documentation to do what I want.
Let's say I have a code like this:
<div id="sourceA">Text</div>
<div id="sourceB">Another</div>
<div id="destination"></div>
Let's say I click on the "sourceA" div, the text contained in it should go in the "destination" div.
Unfortunately, I have no idea how to do it. Can you help me? And maybe also suggest me somewhere I can go and learn something more about this code?

Read more about JavaScript and jQuery events. What you need here is a .click() event on sourceA to handle your behaviour as follows:
$("#sourceA").click(function() {
$("#destination").html($(this).html());
});

HTML:
<div id="sourceA" class="source">Text</div>
<div id="sourceB" class="source">Another</div>
<div id="destination"></div>
JS:
$('.source').click(function(e) {
$('#destination').text($(e.currentTarget).text())
});

Take a look at this example
var copyContentToDestinationClickHandler = function(event) {
$('#destination').empty();
$('#destination').append($(event.target).text());
}
$('#sourceA').click(copyContentToDestinationClickHandler);
$('#sourceB').click(copyContentToDestinationClickHandler);

Javascript code to open a url on click in the same window

Im' stuck in a probably easy problem. Sorry I'm a beginner !
I have this
<div class="icon-1"></div>
<div class="icon-2"></div>
<script>
$(function() {
onclick('icon-1').openurl('http://acdefg.com');
onclick('icon-2').openurl('http://ghijkl.com');
}
</script>
...I mean, that if I click on "icon-1", then I go to URL "...."
If i click on "icon-2" then I go to URL "..."
etc.
Could you please help me ?
Well, you could define something like:
document.getElementByClassName("icon-1").onclick=function(){
window.location.href = 'http://abcdef.com';
};
You could also pull in an elements attribute (for examle, data-href) to full in the variable (instead of setting it specifically in JS, then you would only need 1 JS function for all occurrences).
However, can I ask - why don't you just use HTML a tags with href values?
Try this using jQuery (which is bundled with WordPress): https://jsfiddle.net/wu24bnbc/2/
<div class="icon-1">Icon 1</div>
<div class="icon-2">Icon 2</div>
<script>
jQuery(function() {
jQuery('.icon-1').click(function() {
window.location.href = 'http://acdefg.com';
});
jQuery('.icon-2').click(function() {
window.location.href = 'http://ghijkl.com';
});
});
</script>
Edit: I think you need to use jQuery instead of the $ shorthand with WP.

How to toggle css visibility with Javascript

I am trying to create a FAQ page much like the one here: https://www.harrys.com/help
I want to create the effect where clicking a question will display an answer.
My code can be seen here: http://jsfiddle.net/8UVAf/1/
Can anybody tell me why my javascript is not working? I realized I combined jQuery and Javascript, but I read somewhere that it should compile fine.
HTML:
<div class="questions-answer-block">
<p class="question">This is a Question?</p>
<p id="answer" class="hideinit">Here is the Answer</p>
</div>
<div class="questions-answer-block">
<p class="question">This is a Question?</p>
<p id="answer" class="hideinit">Here is the Answerdadawdawdawdawdawdawdawdwadawdawdawdawdawdawdawdawdawdawdawdawdawdawdawdawdawdawdawdawdawdawdawdawdawdawdawdawd</p>
</div>
JS:
$(".question").click(function (argument) {
if(document.getElementById("answer").className.match(/(?:^|\s)hideinit(?!\S)/)) {
document.getElementByID("answer").className = "display";
}
});
Basically your Javascript could be shortened to:
$(".question").click(function(argument) {
$(this).parent().find(".answer").removeClass("hideinit").addClass("display");
});
In order to make this work the only other thing you need to do is to make question a class rather than as an id. That looks like:
<p class="answer hideinit">the answer</p>
See the fiddle here
Edit: Add Hide / Show
To get this to hide and show as expected you'll want to update the code to check the current class before hiding and showing. That looks like:
$(".question").click(function(argument) {
var el = $(this).parent().find(".answer");
if (el.hasClass("display")) {
el.removeClass("display").addClass("hideinit");
} else {
el.removeClass("hideinit").addClass("display");
}
});
See the fiddle here
Well, for one thing, in your JSFiddle you were not including the jQuery library. I've adjusted your code, I think this is what you were going for:
$(".question").click(function() {
$(this).siblings().toggle();
});
Here's an updated JSFiddle.
Please watch your includes in your JSFiddle as the version you linked was not including the jQuery library. You should also clean up your multiple id references (as this is invalid HTML and will cause some issues down the road).
Those issues aside, you can use jQuery's .next() method to help you with this particular problem:
$(".question").click(function (argument) {
$(this).next(".hideinit").removeClass("hideinit").addClass("display");
});
JSFiddle
$(".question").on('click',function() {
$(this).next().toggle();
});

Get onClick element to return to the main element?

I'm awful with javascript and I'm having a problem with this one.
I'm using this code
<script>
function changeNavigation(id){
document.getElementById('members')
.innerHTML=document.getElementById(id).innerHTML
}
</script>
and HTML
`<span onClick="changeNavigation('members')" >MEMBERS</span>
<span onClick="changeNavigation('help')" >HELP</span>`
<div id="members>...</div>
<div id="help" style="display: none;>...</div>
But I can't get <span onClick="changeNavigation('members')" >MEMBERS</span> to actually go to an element "members" without duplicating everything inside of it in another id.
Is there a way to do this?
This can be done using only standard javascript, but personally I'd recommend going ahead and getting used to using jQuery. Here's an example jsfiddle using jQuery: http://jsfiddle.net/JnvCR/2/
Don't forget to include jQuery in your website:
<script src="http://code.jquery.com/jquery.js"></script>
You need to correct your syntax errors. Use onclick instead of onClick (pedantic). Make sure you close your attributes properly, you are missing a few closing " marks.
updated html
<span onclick="changeNavigation('members')" >MEMBERS</span>
<span onclick="changeNavigation('help')" >HELP</span>`
<div id="members">...</div>
<div id="help" style="display: none;">...</div>
There is also an error with your logic as you are simply replacing the contents of div#members with itself.
Updated JS without syntax errors, but still with dodgy logic
function changeNavigation(id){
document.getElementById('members').innerHTML=document.getElementById(id).innerHTML;
}

As far as your actual question goes, can you explain what you would like to happen a bit better??

javascript change div html when click span

Ok I have a small question.
I have the following
<div><span class="spanright" onclick"">Update</span><label class="myinfo"><b>Business information:</b></label></div>
What I want to do is when the user clicks on the span it changes the html after the label an adds an input box and submit button.
I think I need to do a this.document but not sure
Hi hope this might give you a small understanding of what to do when it comes to registering events. StackOverflow is about you learning how to do something, so we dont write the scripts for you, we are just trying to point you in the right direction of it.

I would recommend you to import jQuery library, as done in the example, if possible. It makes the the world of javascript alot easier!
Documentation to look up:
http://api.jquery.com/insertAfter/
http://api.jquery.com/bind/
Look up some jQuery tutorials! there is alot of them out there.
I added a form which will hold the input
JavaScript:
function showInput()
{
document.getElementById('container').innerHTML += '<input type="text"/><input type="submit"/>';
}
HTML:
<div id="container">
<span class="spanright" onclick"showInput()">Update</span>
<label class="myinfo"><b>Business information:</b></label>
</div>
Summoner's answer is right, but I prefer using jquery (it's loaded on almost every page I work with):
HTML:
<div id="container">
<span class="spanright">Update</span>
<label class="container"><b>Business information:</b></label>
</div>​
Javascript:
​$(".spanright").click(function(){
$("#container").append('<br /><input type="text"/><input type="submit"/>');
$(".spanright").unbind('click');
})​​;​
This way, the click event will work once, as it is what you probably intended.
Try this in jquery flavor --
$(document).ready(function(){
$(".spanright").click(function(){
$(".myinfo").css("color","red");
});
});

Can't fire click event on the elements with same id

Could you help me to understand - where I made the mistake. I have the following html code:
<div id="container">
Info mail.ru
</div>
<div id="container">
Info mail.com
</div>
<div id="container">
Info mail.net
</div>
and the following js code (using jQuery):
$('#getInfo').click(function(){
alert('test!');
});
example here
"Click" event fired only on first link element. But not on others.
I know that each ID in html page should be used only one time (but CLASS can be used a lot of times) - but it only should (not must) as I know. Is it the root of my problem?
TIA!
upd: Big thx to all for explanation!:)
Use a class for this (and return false in your handler, not inline):
<div id="container">
Info mail.ru
</div>
<div id="container">
Info mail.com
</div>
<div id="container">
Info mail.net
</div>
$('.getInfo').click(function(){
alert('test!');
return false;
});
http://jsfiddle.net/Xde7K/2/
The reason you're having this problem is that elements are retrieved by ID using document.getElementById(), which can only return one element. So you only get one, whichever the browser decides to give you.
While you must, according to the W3 specifications, have only one element with a given id within any document, you can bypass this rule, and the issues arising from the consequences if document.getElementById(), if you're using jQuery, by using:
$('a[id="getInfo"]').click(function() {
alert('test!');
return false;
});
JS Fiddle demo.
But, please, don't. Respect the specs, they make everybody's life easier when they're followed. The above is a possibility, but using html correctly is much, much better for us all. And reduces the impact of any future changes within the browser engines, jQuery or JavaScript itself.
It must only be used once or it will be invalid so use a class instead, return false can also be added to your jQuery code as so: -
$('.getInfo').click(function(){
alert('test!');
return false;
});
<a href="#info-mail.net" **class**="getInfo" ....
First id's are for one element only, you should have same id for several divs.
you can make it class instead.
your example changed:
<div class="container">
<a href="#info-mail.ru" class="getInfo" >Info mail.ru</a>
</div>
<div class="container">
<a href="#info-mail.com" class="getInfo" >Info mail.com</a>
</div>
<div class="container">
<a href="#info-mail.net" class="getInfo" >Info mail.net</a>
</div>
$('.getInfo').click(function(ev){
ev.preventDefault(); //this is for canceling your code : onClick="return false;"
alert('test!');
});
You can use the same id for several element (although the page won't validate), but then you can't use the id to find the elements.
The document.getElementById method only returns a single element for the given id, so if you would want to find the other elements you would have to loop through all elements and check their id.
The Sizzle engine that jQuery uses to find the elements for a selector uses the getElementById method to find the element when given a selector like #getInfo.
I know this is an old question and as everyone suggested, there should not be elements with duplicate IDs. But sometimes it cannot be helped as someone else may have written the HTML code.
For those cases, you can just expand the selector used to force jQuery to use querySelectorAll internally instead of getElementById. Here is a sample code to do so:
$('body #getInfo').click(function(){
alert('test!');
});
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"></script>
</head>
<body>
<div id="container">
Info mail.ru
</div>
<div id="container">
Info mail.com
</div>
<div id="container">
Info mail.net
</div>
</body>
