replace content of div with another content - javascript

I've been building a list of links, all of which should change the content of a div to another specific content (about 4 lines of stuff: name, website, contact etc.) upon a click.
I found this code:
<script type="text/javascript">
function ReplaceContentInContainer(id,content) {
var container = document.getElementById(id);
container.innerHTML = content;
}
</script>
and used it in such a way:
<li class="pl11">
superlink')">Pomorskie</a>
</li>
And it doesn't work as I expected.
It changes hyperlinks text from 'Pomorskie' to 'superlink'.
The plain text works just fine but I need links.
here's the http://xn--pytyfundamentowe-jyc.pl/projektanci/kontakty-p/ (only two of them show anything)
But after trying all of your recomendations, I think I'd jump to different divs with #links, cause nothing worked with this :/
Thanks a lot for trying, and cheers :)

Just as a completely sideways look at this, I'd suggest avoiding the nesting weirdness / complexity, and reducing the problem down.
Setup the content in a hidden (ie. <div id="replacements">...</div>) Grab the innerHTML from the node you want, and be done with it.
Much easier to get replacement content from non-devs that way too, kinda works great if you're in a team.
// Probably better in a separate helpers.js file.
function replaceContentInContainer(target, source) {
document.getElementById(target).innerHTML = document.getElementById(source).innerHTML;
}
Control it with: (lose that href=javascript: and use onClick, better as an event handler, but for brevity I'll inline it as an onClick attribute here, and use a button.)
<button onClick="replaceContentInContainer('target', 'replace_target')">Replace it</button>
We have our target somewhere in the document.
<div id="target">My content will be replaced</div>
Then the replacement content sits hidden inside a replacements div.
<div id="replacements" style="display:none">
<span id="replace_target">superlink</span>
</div>
Here it is in JSBin
Improve the dynamic nature of this by using Handlebars or another nice JS templating library, but that's an exercise for the OP.
edit: Note, you should also name functions with a leading lowercase letter, and reserve the leading uppercase style for Class names e.g. var mySweetInstance = new MySpecialObject();

The quotes are mismatched! So when you click you are getting a JavaScript error.
The browser sees this string:
href="javascript:ReplaceContentInContainer('wojewodztwo', 'superlink')">Pomorskie<
as:
href="javascript:ReplaceContentInContainer('wojewodztwo', '<a href="
Chnage the " inside to #quot;
<li class="pl11">
Pomorskie
</li>
Example fiddle.
Also note, using the href tag for JavaScript is a BAD practice.

You've got a problem with nested quotes. Take a look in your DOM inspector to see what the HTML parser built from it! (in this demo, for example)
You either need to HTML-escape the quotes inside the attribute as " or ", or convert them to apostrophes and escape them inside the JS string with backslashes:
<a href="j[…]r('wojewodztwo', '<a href="http://address.com">superlink</a>')">…
<a href="j[…]r('wojewodztwo', '<a href=\'http://address.com\'>superlink</a>')">…
See working demos here and here.
Better, you should use a onclick attribute instead of a javascript-pseudo-url:
<a onclick="ReplaceContentInContainer('wojewodztwo', …)">Pomorskie</a>
or even a javascript-registered event handler:
<li class="pl11">
<a id="superlink">Pomorskie</a>
</li>
<script type="text/javascript">
function replaceContentInContainer(id,content) {
var container = document.getElementById(id);
container.innerHTML = content;
}
document.getElementBId("superlink").onclick = function(event) {
replaceContentInContainer('wojewodztwo', 'superlink');
event.prevenDefault();
};
</script>

How to substitute specific pages? [HTML Multilingual Website]

My question is pretty straight forward.
I have a static HTML website in English.
www.website.com
www.website.com/services
www.website.com/contacts
I also have it translated in German:
www.website.com/de/
www.website.com/de/services
www.website.com/de/contacts
My button (flag) for changing language is located next to my navigation:
<ul class="language">
<li class="de"></li>
</ul>
Option 1: I can just replace the "#" with the German version of the page. For example on www.website.com it is <a href="www.website.com/de/"> and on www.website.com/services it is <a href="www.website.com/de/services">
But this is so much work. Is there an easier way for calling pages by using javascript or .htaccess..or whatever you suggest.
My pages are in .html, so the .php option isn't efficient. And adding "id" to every element in order to translate it.. is even more complicated than the first option.
Thanks in advance!
Ideally, you should probably do that with the server-side language of your website (PHP / ASP / Java / …). If you still want to do it in Javascript, you can do something like that to add /de on front of your current location:
<a href="www.website.com/de/" id="language">
<script>document.getElementById('language').setAttribute('href', '/de'+document.location.pathname);</script>
yep I suspect this javascript should work:
$(document).ready(() => {
let path = window.location.pathname;
if (path.startsWith('/de'))
$('a.lang-switch').attr('href', path.substr(3));
else
$('a.lang-switch').attr('href', '/de' + path);
console.log($('a').attr('href'));
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<a class="lang-switch">Change Language</a>
Do you have two distinct copies of the HTML? If so, this is probably pretty easy.
Go with your first option, but only for changing languages.
Include a <meta> tag that indicates the current language
Use a javascript event listener to intercept each link clicked and insert the language based on the above meta tag. Something like this;
let lang = document.getElementsByName('lang')[0].getAttribute('lang');
// Get the parent DIV, add click listener...
document.body.addEventListener("click", function(e) {
// e.target was the clicked element
if(e.target && e.target.nodeName == "A") {
e.target.href.replace('yourwebsite.com', `yourwebsite.com/${lang}/`);
}
});
<meta name='lang' lang='de'>

Remove any specific html code using javascript

In the past I used Google Developer Console to delete some specific divs on a page. I could do it manually of course but in some cases where the divs where many I had to use the console. I had a single line code that did the job (I found it while searching the internet) but I lost my note.
So how can I delete using javascript any html code (by copy pasting the code).
Something like:
elements = $('<div ... </div>');
elements.remove();
OR
$('<div ... </div>').remove();
Any ideas? I am not an expert in javascript (obviously) and I've been searching stackoverflow for hours without finding anything that works.
UPDATE: I think some people might get confused with my question. Google developer console accepts javascript command lines. So even though I ask for javascript I will use the code on the google developer console.
UPDATE 2 :
Here is an example of a div I need to delete. Keep in mind I want to copy paste the entire code in the javascript code. Not just identify the div.
<div class="entry-status-overlay" data-entry-status="declined">
<div class="entry-status-overlay__inner">
<span class="entry-status-overlay__title">Declined</span>
</div>
</div>
It's the data-entry-status="declined" that makes that div unique so I can't just identify the div using an id selector or a class selector. I need to put the entrire thing there and remove it.
I tried:
$('<div class="entry-status-overlay" data-entry-status="declined"><div class="entry-status-overlay__inner"><span class="entry-status-overlay__title">Declined</span></div></div>').remove();
It didn't remove the div.
Try to search the dom by its outerHTML.
function deleteDomByHtml(html){
html=html.replace(/\s/g,'');
$("*").each(function(){
if(this.outerHTML.replace(/\s/g,'')===html){
$(this).remove();
}
});
}
And try this line on this page:
deleteDomByHtml(`<span class="-img _glyph">Stack Overflow</span>`);
You cannot do by simply pasting the code. That will remove all the div element.
You may need a specific selector like id,class or child to specific parent to remove the element from the dom.
Consider this case the divs have common class but the data-entry-status is different. So you can get the dom using a selector and then check the dataset property.
For demo I have put it inside setTimeout to show the difference. In application you can avoid it
setTimeout(function() {
document.querySelectorAll('.entry-status-overlay').forEach(function(item) {
let getStatus = item.dataset.entryStatus;
if (getStatus === 'declined') {
item.remove()
}
})
}, 2000)
<div class="entry-status-overlay" data-entry-status="declined">
<div class="entry-status-overlay__inner">
<span class="entry-status-overlay__title">Declined</span>
</div>
</div>
<div class="entry-status-overlay" data-entry-status="accepted">
<div class="entry-status-overlay__inner">
<span class="entry-status-overlay__title">accepted</span>
</div>
</div>
Just add any attribute with [] and it will remove the element.
$('[class="entry-status-overlay"]').remove();
/*OR*/
$('[data-entry-status="declined"]').remove();
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.0/jquery.min.js"></script>
<div class="entry-status-overlay" data-entry-status="declined">
<div class="entry-status-overlay__inner">
<span class="entry-status-overlay__title">Declined</span>
</div>
</div>
function del(){
var h = document.body.outerHTML;
h = h.match('<div>...</div>');
h.length--;
return h;
}
I guess this will work just give it a try... i tried on browser console and it worked, this way you can match the exact you want.
I might as well add my take on this. Try running this in your console and see the question vanish.
// convert the whole page into string
let thePage = document.body.innerHTML,
string = [].map.call( thePage, function(node){
return node.textContent || node.innerText || "";
}).join("");
// I get some string. in this scenario the Question or you can set one yourself
let replacableCode = document.getElementsByClassName('post-layout')[0].innerHTML,
string2 = [].map.call( replacableCode, function(node){
return node.textContent || node.innerText || "";
}).join("");
// replace whole page with the removed innerHTML string with blank
document.body.innerHTML = thePage.replace(replacableCode,'');
If you want to identify divs with that particular data attribute, you can use a data-attribute selector. In the example below, I've used a button and click event to make the demo more visual, but in the console the only line you'd need would be:
$('div[data-entry-status="declined"]').remove();
$(function() {
$("#testbutton").click(function() {
$('div[data-entry-status="declined"]').remove();
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="entry-status-overlay" data-entry-status="declined">
<div class="entry-status-overlay__inner">
<span class="entry-status-overlay__title">Declined</span>
</div>
</div>
<div id="x">Some other div</div>
<button type="button" id="testbutton">Click me to test removing the div</button>
See https://api.jquery.com/category/selectors/attribute-selectors/ for documentation of attribute selectors.
P.S. Your idea to paste some raw HTML into the jQuery constructor and then execute "remove" on it cannot work - you're telling jQuery to create an object based on a HTML string, which is, as far as it's concerned, a new set of HTML. It does not try to match that to something existing on the page, even if that exact HTML is in the DOM somewhere, it pays it no attention. It treats what you just gave it as being totally independent. So then when you run .remove() on that new HTML...that HTML was never added to the page, so it cannot be removed. Therefore .remove() has no effect in that situation.

Spacing different in original html rendering vs dynamic JS rendering

Here is a small part of my page:
<a href="#" onclick="PolicyViolation(<%: ViewBag.DeviceData[i].DeviceID%>); return false;">
<span class="policyViolationsNumber"><%= ViewBag.DeviceData[i].ViolationCount%></span>
<span>Policy Violations</span>
</a>
This renders out to have some space between the two spans.
In code, we update this in JS:
var spanViolationNumber = $('<span>')
.html(statusModel.Violations)
.addClass('policyViolationsNumber');
var spanViolationString = $('<span>')
.html('<%=ServiceSite.Resources.Resources.DEVICES_POLICY_VIOLATIONS%>');
var imageTag = $('<img>')
.attr('src', '/Content/images/error_error.png')
.attr('align', 'absmiddle');
var anchorTag = $('<a href="#">')
.append(spanViolationNumber)
.append(spanViolationString);
cell.empty();
cell.append(imageTag)
.append(anchorTag);
However, this renders out with no space between the spans. I've seen small issues like this before but never figured out what it is. You can ignore the image tag stuff, it is irrelevant.
EDIT:
Didn't know about this, I guess it's expected behaivor: http://jsfiddle.net/2MMuA/
The extra space is happening because of the way you are formatting your HTML.
The "span" tag is an inline HTML element. This basically means you need to treat it just as you would treat text on the page.
<span>Hello</span> <span>World</span>
<!-- Prints Hello World -->
<span>Hello</span>
<span>World</span>
<!-- Prints Hello World
The line break is where your extra space is coming from. -->
<span>Hello</span><span>World</span>
<!-- prints HelloWorld
This is how the ".append()" function is formatting the HTML.
It adds it literally right after the last character in the HTML. -->
In order to normalize this across the two different techniques, you either have to butt your "span" tags right up next to each other so the HTML doesn't add an extra space...
<span></span><span></span>
..or you need to manually add the space in your ".append()" function.
obj.append(' ' + spanTag);
I hope that helps!
Perhaps you could clarify .. are you talking about there being space between these spans?
<span class="policyViolationsNumber">12</span>
<span>Policy Violations</span>
Either way I would look at adding some padding or margin to your css to insure you get the space that you want OR at minimum (though not recommended) use an HTML encoded space like so
There is most likely spaces between your spans. If you put the spans exactly next to each other then there should be no spaces.
<span></span><span></span>

JS - Shouldn't this be written better? One function vs multiples?

I have a tweet stream where new tweets are added at the top and the older ones pushed down. You can click on the entire tweet and a panel slides down to reveal, "reply", "retweet", "favorite" etc. The panel is added to each new tweet added in the stream.
The code below works. Shouldn't this be better written so that only one call is being made? Or, as a new tweet is added. would I just have to add to the code with div#tc4, ul#tb4 etc?
$(document).ready(function () {
$("div#tc1").click(function () {
$("ul#tb1").slideToggle("fast");
});
$("div#tc2").click(function () {
$('ul#tb2').slideToggle("fast");
});
$("div#tc3").click(function () {
$('ul#tb3').slideToggle("fast");
});
});
Added Markup:
<div id="tc1" class="tweetcontainer">
<div class="avatarcontainer">
<div class="avatar"></div>
</div>
<div class="content">
<div class="tweetheader">
<div class="name">
<h1>John Drake</h1>
</div>
<div class="tweethandle">
<h2>#Drakejon</h2>
</div>
<div class="tweettime">10m</div>
</div>
<div>

<!-------------Tool Bar -------------------------------->
<ul id="tb1" class="toolbar">
<li><a class="reply" href="#"><span>reply</span></a></li>
<li><a class="retweet" href="#"><span>retweet</span></a></li>
<li><a class="favorite" href="#"><span>favorite</span></a></li>
<li><a class="track" href="#"><span>track</span></a></li>
<li><a class="details" href="#"><span>details</span></a></li>
</ul>
I highly recommend separating your javascript from your detailed page function. The best way to do this is to put the retweeting panel inside the tweet container, then you don't even need to give it an id at all or encode in the javascript information about your html structure and ids. You can then just do:
$('.tweetcontainer').on('click', function(event) {
if ($(event.target).is(':descendantof(.toolbar)')) {
//ignore all clicks within the toolbar itself
return;
}
$(this).find('.toolbar').slideToggle();
});​
It's that easy! See it in action in a jsFiddle.
Now you can add as many tweet containers as you want to your page--and your javascript doesn't have to change one bit. Other solutions that require knowledge of specific ids linking to specific ids are suboptimal.
Note the descendantof pseudo-selector is custom (see the fiddle to find out how it works). Also, since you didn't provide any css, I had to choose some--it was quick so don't expect much. (Aww heck I just saw you updated your question to provide a jsFiddle with css giving a far prettier result--but I won't change mine now.) I did have to add a class to the actual tweet itself, but there is probably a better way to style it.
And if you want a click on the displayed toolbar itself (outside of a link) to allow collapsing the toolbar, change the code above to :descendantof(a).
If you don't want to change your page layout, another way to it is to encode the information about the linkage between html parts in the html itself using a data attribute. Change your tweetcontainer div to add a data attribute with a jQuery style selector in it that will properly locate the target:
<div class="tweetcontainer" data-target="#tb1">
You don't really have to remove the id if you use it elsewhere, but I wanted you to see that you don't need it any more. Then on document.ready:
$('.tweetcontainer').click(function () {
$($(this).data('target')).slideToggle('fast');
});
Here is another jsFiddle demonstrating this alternate technique (though it less elegant, in my opinion).
Last, I would like to mention that it seems possible you have a little bit of "div-itis". (We have all been there.) The toolbar anchor elements have unnecessary spans inside of them. The tweet name h1 element is inside a div, but could just be an h1 with class="name" instead.
In general, if there is only a single item inside a div and you can change your stylesheet to eliminate the div, then the div isn't needed. There are an awful lot of nested divs in your html, and I encourage you to remove as many of them as you can. Apply style to the other block elements you use and at least some, if not many, won't be needed.
I'd suggest (though currently untested):
$('div[id^="tc"]').click(function(){
var num = parseInt(this.id.replace(/\D+/g,''),10);
$('#tb' + num).slideToggle("fast");
});
Though given that you don't need the num to be a number (it'd be fine as a string), you could safely omit the parseInt().
Yes, you can write this code much more compactly like this:
$(document).ready(function() {
for (var i = 1; i < 3; i++) {
$("div#tc" + i).click(function() { $("ul#tb" + i).slideToggle("fast"); } );
}
});

JQuery Copy text & paste into textarea

I've created a javascript function that will take a hidden span, copy the text within that span and insert it into a single textarea tag on a website. I've written a function in JavaScript that does this (well, kinda, only after a few clicks), but I know there's a better way - any thoughts? The behavior is similar to a Retweet for twitter, but using sections of a post on a blog instead. Oh, and I'm also calling out to jquery in the header.
<script type="text/javascript">
function repost_submit(postID) {
$("#repost-" + postID).click(function(){
$("#cat_post_box").empty();
var str = $("span#repost_msg-" + postID).text();
$("#cat_post_box").text(str);
});
}
</script>
Based on the comment in your question, I am assuming you have something like this in your HTML:
copy post
And I am also assuming that because you are passing a post ID there can be more than one per page.
Part of the beauty of jQuery is that you can do really cool stuff to sets of elements without having to use inline Javascript events. These are considered a bad practice nowadays, as it is best to separate Javascript from your presentation code.
The proper way, then, would be to do something like this:
<a href="#" id='copy-5' class='copy_link'>copy post</a>
And then you can have many more that look similar:
<a href="#" id='copy-5' class='copy_link'>copy post</a>
<a href="#" id='copy-6' class='copy_link'>copy post</a>
<a href="#" id='copy-7' class='copy_link'>copy post</a>
Finally, you can write code with jQuery to do something like this:
$(function() { // wait for the DOM to be ready
$('a.copy_link').click(function() { // whenever a copy link is clicked...
var id = this.id.split('-').pop(); // get the id of the post
var str = $('#repost_msg-' + id); // span not required, since it is an ID lookup
$('#cat_post_box').val(str); // empty not required, and val() is the proper way to change the value of an input element (even textareas)
return false;
});
});
This is the best way to do it even if there is only one post in the page. Part of the problem with your code is that on the first click it BINDS the function, and in the subsequent clicks is when it finally gets called. You could go for a quick and dirty fix by changing that around to just be in document.ready.
$("#repost-" + postID).click(function(){
$("#cat_post_box").val(''); // Instead of empty() - because empty remove all children from a element.
$("#cat_post_box").text($("#repost_msg-" + postID).text());//span isn't required because you have and id. so the selector is as efficient as it can be.
});
And wrap everything in a $(document).ready(function(){ /Insert the code here/ }) so that it will bind to $("#repost-" + postID) button or link when the DOM is loaded.
I had a problem with Paolo's example when I clicked on the link the text that appeared in #cat_post_box was "object Object". Once I added ".text()" to the end of that statement I worked.
var str = $('#repost_msg-' + id).text();
Thanks for you example Paolo!
