Toggle script: change from jQuery to "normal javascript" code - javascript

I've been using a toggle script (open/close text container when clicking on a certain link) for a website that uses jQuery. In order to clean up the website I want to get rid of jQuery completely but have some problems converting the existing jQuery code into "normal javascript".
Here is the existing code:
jQuery(function($){
$(document).ready(function(){
$(".toggle_container").hide();
$("h4.trigger").click(function(){
$(this).toggleClass("active").next().slideToggle("normal");
return false; //Prevent the browser jump to the link anchor
});
});
});
Which corresponds to this HTML source code:
<h4 class="trigger toggle-transparent ">Click to show more</h3><div class="toggle_container ">
Hidden Text
</div>
I've tried the following code which doesn't give me an error but just doesn't do anything when clicking on the trigger:
var el = document.querySelectorAll('h4.trigger');
for(var i=0; i < el.length; i++){
el[i].addEventListener('click', function () {
this.classList.toggle("active").nextSibling.classList.toggle("toggle_container-active");
}.bind(this));
}
The only thing I really need for the code is: clicking on the class "trigger" should toggle some HTML class "active" to both the trigger element as well as the toggle_container element. The rest I'm able to change with just CSS.
The hard part of the code is that it should work for multiple toggle areas on one page separately (therefore using a class, not an id).
Any idea where my code has a problem or any (completely) different suggestions?
I have very limited experience with javascript/jQuery and feel more at home with HTML/CSS.
Thanks,
Patrick

The this.classList.toggle("active") doesn't return the element back again, but just a boolean to inform if the action was successful. Chaining happens only in jQuery and not in vanilla JavaScript.
this.classList.toggle("active").nextSibling.classList.toggle("toggle_container-active");
You should be using something like this instead of the above:
this.classList.toggle("active");
this.nextSibling.classList.toggle("toggle_container-active");

Javascript - Click list element to load HTML page animation

Javascript novice here. I am working on a piece of code provided here - http://codepen.io/mariusbalaj/pen/beALH/
I'm trying to modify the behavior so that instead of just zooming in the list element when clicked, it should load a different html page within the animated frame.
$(document).ready(function() {
var $box = $('.box');
$('.metro li').each(function() {
var color = $(this).css('backgroundColor');
var content = $(this).html();
$(this).click(function() {
$box.css('backgroundColor', color);
$box.addClass('open');
$box.find('p').html(content);
});
$('.close').click(function() {
$box.removeClass('open');
$box.css('backgroundColor', 'transparent');
});
});
});
Can anyone point me to the right direction?
Update 1 :
I figured out that modifying the 'content' variable on the below line would change the content of the animated frame:
` $box.find('p').html(content);`
And if I change it to something like:
` $box.find('p').html('<h1>Test Page</h1>');`
It works as expected. However, I want the content to be different for each list element.
Is there an easy way of doing this per element? I am quite confused with the 'this' keyword.
You may be looking for this answer, if you want to open another HTML page:
how to change page from within javascript
If you're trying to open it WITHIN the animated frame, you should look into making some requests to the content of the new page/tile and filling that with content, which is answered here: How to get the response of XMLHttpRequest?
It all depends what you want to do, let us know :)

shorthand for .load() ajax links with loader

here's the structure of the code: http://jsfiddle.net/ss1ef7sq/
although it's not really working at js fiddle but the code itself is working as i've tested it locally through firefox.
this is where i've based this on: http://html.net/tutorials/javascript/lesson21.php
jquery/ajax:
$('#ep-101').click(function(){$('.main-container').load('link.html #ep101').hide().fadeIn(800);});
$('#ep-102').click(function(){$('.main-container').load('link.html #ep102').hide().fadeIn(800);});
$('#ep-103').click(function(){$('.main-container').load('link.html #ep103').hide().fadeIn(800);});
$('#ep-104').click(function(){$('.main-container').load('link.html #ep104').hide().fadeIn(800);});
$('#ep-105').click(function(){$('.main-container').load('link.html #ep105').hide().fadeIn(800);});
so my question is, is there a way to make it like a shorter code where it can just get the value of those #10ns or assuming that there will be a different page with it's own nest of unique ids without typing them individually? there's still a lot i don't understand with ajax so i'd appreciate it if anyone can help & explain at least the gist of it as well.
i've looked around online but i'm really stuck. i also at least found out that it's possible to add transitions but the way it's coded there is that it will only have the transition for the incoming page & not the one that will be replaced. i also have a prob with page loaders effects but i'll save it for when i'm stuck there as well.
thanks in advance. =)
Use classes instead of id's. Set href attribute which you want to load on click and access it via $(this).attr('href').
<a class="load-me" href="link1.html">link 1</a>
<a class="load-me" href="link2.html">link 2</a>
...
Script:
$('.load-me').click(function(e){
e.preventDefault();
$('.main-container').hide().load($(this).attr('href'), function() {
// ...
$(this).fadeIn(800);
})
});
JSFiddle
If you need the load to wait container hiding animation, you could make it other way.
$('.load-me').click(function(e){
e.preventDefault();
// get the url from clicked anchor tag
var url = $(this).attr('href');
// fade out the container and wait for animation complete
$('.main-container').fadeOut(200, /* animation complete callback: */ function(){
// container is hidden, load content:
$(this).load(url, /* load complete callback: */ function() {
// content is loaded, show container up
$(this).slideDown(200);
});
});
});

casperjs: how do I click a remote div and then update it's class name?

As a way of learning CasperJS, I am trying to initiate a click event on a div on a remote page, and then change the class name of the div after I have clicked it. The idea is to find the first clickable div, click it, and then mark it as clicked so I can skip over it to other clickable divs. The markup for the div tag on the remote page looks like:
<div class='clickable_div'></div>
I have tried the following casperjs code:
...
casper.then(function() {
if( this.exists( 'div.clickable_div' ) ) {
this.evaluate(function() {
this.click(document.querySelector('div.clickable_div'));
return document.querySelector('div.clickable_div').setAttribute("className","clicked");
});
}
});
...
It doesn't seem to work. First, I don't think I am initiating the mouse click event on the div correctly. What am I missing? Second, when I fetch the updated html, I don't see any changes in the div's class name. Am I going about this step in the wrong way?
You're calling this.click within evaluate(), it just can't work as evaluate() executes code within the page DOM context where there's probably no window.click method.
Here's a possibly working script:
var linkSelector = 'div.clickable_div';
casper.then(function() {
if (!this.exists(linkSelector)) return;
this.click(linkSelector);
this.evaluate(function(linkSelector) {
__utils__.findOne(linkSelector).setAttribute("className", "clicked");
}, linkSelector);
});
You may want to have better handling of errors and edge cases, but you get the idea.

How to get Anchor Links to work in Jquery Mobile?

Jquery Mobile has decided to treat anchor links as page requests of sort. However, this isn't good if you have a load of blog posts which have anchor links to the same page (ie href="#specs").
Is there a way to disable jquery mobile's anchor link usage on a specific page which I know I won't be using it on so I can use anchor links as they were intended, to drop down to a part of the page?
I only need a solution for anchor links on the same page (ie: href="#specs").
thanks
You could try adding a data-ajax="false" on the anchor tag.
Linking without Ajax
Links that point to other domains or that have rel="external",
data-ajax="false" or target attributes will not be loaded with Ajax.
Instead, these links will cause a full page refresh with no animated
transition. Both attributes (rel="external" and data-ajax="false")
have the same effect, but a different semantic meaning: rel="external"
should be used when linking to another site or domain, while
data-ajax="false" is useful for simply opting a page within your
domain from being loaded via Ajax. Because of security restrictions,
the framework always opts links to external domains out of the Ajax
behavior.
Reference - http://jquerymobile.com/demos/1.0.1/docs/pages/page-links.html
If you are like me, converting an existing site and you don't want to go through every page right now. You can add one line of code to your header and all of your header and all of your existing internal anchor links will get the data-ajax="false" tag added.
Of course, this assumes you are including your own javascript file up in the header already. If you are not you would have to touch every page anyway. But I have a single javascript file that is included in every page already so I added this line...
$("a").each(function () { if(this.href.indexOf("#")>=0) $(this).attr("data-ajax",false); });
This goes in your $(document).ready() block. If you don't have that block yet, here is the entire block.
$(document).ready(function() {
$("a").each(function () { if(this.href.indexOf("#")>=0) $(this).attr("data-ajax",false); });
});
Hope this helps. It is the same solution user700284 offers but in an automated way.
You can add the following code to the end of your page:
<script type="text/javascript">
$('a.native-anchor').bind('click', function(ev) {
var target = $( $(this).attr('href') ).get(0).offsetTop;
$.mobile.silentScroll(target);
return false;
});
</script>
And add the class "native-anchor" to your anchor links.
It is not a total sollution, because the back button of your browser will move you to the previous page and not to the position of the link, but it is better than the links not working at all.
I found this sollution here: jQuery Mobile Anchor Linking
$(document).bind("mobileinit", function () {
$.mobile.ajaxEnabled = false;
});
First you have to place this code into a custom.js file
$(document).bind('mobileinit', function () {
$.mobile.loader.prototype.options.disabled = true;
$.mobile.ajaxEnabled = false;
$.mobile.linkBindingEnabled = false;
$.mobile.loadingMessage = false;
});
Then add this file into your webpage before the jquery mobile js is loaded. becuase 'mobilinit' event is triggered immediately
Thank you
this solution worked for me
<script>
$(document).ready(function() {
$("a").each(function() {
if (this.href.indexOf("index.php") >= 0) $(this).attr("data-ajax", false);
});
});
</script>
I replaced # with index.php which is my document root.
But, it doesn't work for form button i.e input type="submit"
// On page load on mobiles only, look for the specific a tag you want to take control over,
// alternatively you can still target all 'a' tags
$('a[href*="#component"]').each(function () {
// then set data-ajax to false,
$(this).attr("data-ajax", false);
// at this point you can add the class to your target a tags.
// You can do it elsewhere but because for this example my
// 'a' tags are automatically generated so I just add the class here
$(this).addClass('in-pagelink');
// then target the class and bind to a click event
$('a.in-pagelink').bind('click', function (ev) {
// here I redirect the page with window.location.assign
// as opposed to window.location.href. I find that it works better
window.location.assign(this.href);
// then I close my navigation menu
closeAll();
});
});

How do I run a jQuery function when any link (a) on my site is clicked

I have a new site build on corecommerce system which does not have much access to HTML and non to PHP. Only thing I can use is JavaScript. Their system is currently not great on page load speed so I wanted at least customers to know something is happening while they wait 5-8 seconds for a page to load. So I found some pieces of code and put them together to show an overlay loading GIF while page is loading. Currently it will run if you click anywhere on the page but I want it to run only when a link (a href) on the site is clicked (any link).
I know you can do a code that will run while page loading but this isn't good enough as it will execute too late (after few seconds)
Anyway, this is my website www.cosmeticsbynature.com and this is the code I use. Any help will be great.
<div id="loading"><img src="doen'tallowmetopostanimage" border=0></div>
<script type="text/javascript">
var ld=(document.all);
var ns4=document.layers;
var ns6=document.getElementById&&!document.all;
var ie4=document.all;
if (ns4)
ld=document.loading;
else if (ns6)
ld=document.getElementById("loading").style;
else if (ie4)
ld=document.all.loading.style;
jQuery(document).click(function()
{
if(ns4){ld.visibility="show";}
else if (ns6||ie4)
var pb = document.getElementById("loading");
pb.innerHTML = '<img src="http://www.cosmeticsbynature.com/00222-1/design/image/loading.gif" border=0>';
ld.display="block";
});
</script>
Doing this will be easier if you include jQuery in your pages. Once that is done, you can do:
$('a').click(function() {
// .. your code here ..
return true; // return true so that the browser will navigate to the clicked a's href
}
//to select all links on a page in jQuery
jQuery('a')
//and then to bind an event to all links present when this code runs (`.on()` is the same as `.bind()` here)
jQuery('a').on('click', function () {
//my click code here
});
//and to bind to all links even if you add them after the DOM initially loads (`on()` is the same as `.delegate()` here; with slightly different syntax, the event and selector are switched)
jQuery(document).on('click', 'a', function () {
//my click code here
});
Note: .on() is new in jQuery 1.7.
what you are doing is binding the click handler to the document so where ever the user will click the code will be executed, change this piece of code
jQuery(document).click(function()
to
jQuery("a").click(function()
$("a").click(function(){
//show the busy image
});
How about this - I assume #loading { display:none}
<div id="loading"><img src="http://www.cosmeticsbynature.com/00222-1/design/image/loading.gif" border=0></div>
<script type="text/javascript">
document.getElementById('loading').style.display='block'; // show the loading immediately
window.onload=function()
document.getElementById('loading').style.display='none'; // hide the loading when done
}
</script>
http://jsfiddle.net/vol7ron/wp7yU/
A problem that I see in most of the answers given is that people assume click events only come from <a> (anchor) tags. In my practice, I often add click events to span and li tags. The answers given do not take those into consideration.
The solution below sniffs for elements that contain both events, which are created with jQuery.click(function(){}) or <htmlelement onclick="" />.
$(document).ready(function(){
// create jQuery event (for test)
$('#jqueryevent').click(function(){alert('jqueryevent');});
// loop through all body elements
$('body *').each(function(){
// check for HTML created onclick
if(this.onclick && this.onclick.toString() != ''){
console.log($(this).text(), this.onclick.toString());
}
// jQuery set click events
if($(this).data('events')){
for (key in($(this).data('events')))
if (key == 'click')
console.log( $(this).text()
, $(this).data('events')[key][0].handler.toString());
}
});
});
Using the above, you might want to create an array and push elements found into the array (every place you see console.log
