Using jQuery .click works but .touchstart desn't

I have a block of working code that allows me to shift from one set of colored items to another based on a span click event that runs in jQuery. I am using wordpress and it requires I spell out jQuery instead of using '$'. In part, it works by moving a variable to the active selection and changing a variety of other properties based on defined variables in the html of that 'span'
I tried changing .click(function f()... to .touchstart(function f()... and it doesn't work when I load the site on mobile. If you think you know the answer, cool. I will now list things I have tried.
This is what my click function looks like:
jQuery(document).ready(function f($) {
jQuery('.changecolor span').click(function f($) {...
});
});
Attempts:
jQuery('.changecolor span').touchstart(function e()
jQuery('.changecolor span').on("tap", function e() {...
My cache is set to auto clear every time I save a new change in, and I've tested this.

$('.changecolor span').on('touchstart',function(ev) {
$('your seletor').trigger(ev);
});

FullPage JS: How to disable it for an unique page?

I have a problem with FullPage JS, and I come to ask for help :)
My problem is: I want to disable FullPage for a single page of my Website.
FullPage is made for little page, but my website has 1 long page, where I want to disable FullPage.
The file has the .ejs extension, instead of .html extension. The pages are in different EJS file.
I searched on the FullPage's Github, and it indicates me the destroy('all') method, but I've found a lot of way to write it, I tried 3 methods, and I don't know why, it doesn't work.
Does any of you know how to disable FullPage JS on a single page of the Website ?
I tried 3 methods.
1st Method tried:
document.querySelector('#destroy').addEventListener('click', function(e){
e.preventDefault();
fullpage_api.destroy('all');
});
2nd Method:
$('#destroy').click(function () {
$.fn.fullpage.destroy('all');
});
3rd Method:
function DestroyFullPage() { //default is 700.
$.fn.fullpage.destroy('all');
}
As Alvaro suggested, I tried something like this:
<script>
window.onload = function() {
alert('Ready ?');
fullpage_api.destroy('all');
alert('Done');
}
</script>
The first alert works fine, but the second never appear on my screen, and FullPage isn't destroyed.
Am I wrong in my syntax ?
Thanks
PS: Excuse my English, I'm french, but at least, I try :D

If you wonder how to use the destroy function, you can check the demo provided on the fullPage.js docs:
https://codepen.io/alvarotrigo/pen/bdxBzv
Which basically uses fullpage.js version 3 (no jQuery required) to do so:
fullpage_api.destroy('all');
There's no difference at all between your 2nd method and the 3rd one. In fact, 3rd method won't work until you call the DestroyFullPage somewhere else.
And the 1st one should only be used when initialising fullPage.js with jQuery. So, using $('#fullpage').fullpage(options) instead of new fullpage('#fullpage', options);

Lightbox.options is not a function - lightbox plugin

I am using this lightbox plugin,
http://lokeshdhakar.com/projects/lightbox2/
https://github.com/lokesh/lightbox2/
I have items on the page similar to the example:
Image #2
Image #3
Image #4
it works fine, but I want to change some options, for that according to the documentation http://lokeshdhakar.com/projects/lightbox2/#options it should be
lightbox.option({
'resizeDuration': 200,
'wrapAround': true
})
however i am getting an error
lightbox.option is not a function
so, how to set the options I need ?
edit: the option snippet I have is AFTER the line where the lightbox js is loaded.
edit2: also the options snippet is inside document ready
edit3: lightbox is loaded and is working fine

As it turned out it has something to do with the version, i was using version 2.7.1, I tried with the version 2.8.1 and the error disappeared

I had same problem using npm. I solved it like this.
import lightbox from 'lightbox2/dist/js/lightbox';
window.lightbox = lightbox;
window.lightbox.option({
disableScrolling: true,
fadeDuration:200,
//other
});

Change the ID of that <div id="lightbox"> to something else. Browsers automatically turn all IDs into global variables, and this is overwriting the global lightbox object.

How to make this grid work

I purchased a html5 theme that I am customizing for my church website. It has two cool features:
A tab script that allows for multiple items to displayed on one page.
a grid that will allow me to display sermons in a series in a neat and orderly way.
Both of these work well when used alone, but when I try to use the grid inside the tabs, no dice.
I am a design guy and know very little about Javascript functions and need help. Here is what the developer, who has not got back with me said to do:
"The grid function is built to run on page load and when you put it inside a tab it doesn’t initialize on page load so don’t work when you change tabs. A custom function needs to be built for this which will run the isotope grid on tabs change. Like:"
$(".nav-tabs li")click(function(e){
ADORE.IsoTope();
e.preventDefault();
}
I do not know where to add this or even if something else needs to be added. I have also attached a link where you can download my code (html/php and .js file) so you can see what is going on. Any help would be appreciated. Remember, I know very little about Javascript.
https://www.dropbox.com/s/jypfjz3a89soxh7/example.zip?dl=0

Add:
$(".nav-tabs li a").click(function(e){
$('a[href="' + $(this).attr('href') + '"]').tab('show');
var IsoTopeCont = $(".isotope-grid");
IsoTopeCont.isotope({
itemSelector: ".grid-item",
layoutMode: 'sloppyMasonry'
});
});
at Line 469 of your init.js and it should work for you. Thanks

You can try the following: inside your init.js add the following:
$(".nav-tabs li").click(function(e){
e.preventDefault();
ADORE.IsoTope();
});
e.g. in the first line after var ADORE = window.ADORE || {};
As you mentioned that you don't know much about javascript: the first line starts with
jQuery(function($){ ...
This takes care about that everything inside the { will get executed when jQuery is loaded.
I'm not sure if the e.preventDefault(); is necessary - this is used e.g. to prevent links from getting executed and attach a different function to the click() event, so it could be possible that Isotope is working when a tab is clicked, but the tab is not working anymore.
If this won't work, you can check with web dev tools if there are any script errors. In case you're unfamiliar with web dev tools, find some details for Firefox here: https://developer.mozilla.org/en-US/docs/Tools/Web_Console and for Chrome here: https://developer.chrome.com/devtools/docs/console

jquery tools overlay - Two on same page

I have been working with jquery tools overlays. I got the below code online and have been able to make it work. However I now need the overlay setup with another link on the same page and need a different size on that overlay.
I tried copying and pasting the code and changing the rel to look for an id. My plan was the get a second function set to different div's, then setup the size in css. I'm rather new to jquery and although I thought it would be easy I cannot figure this out.
If anyone has any better solutions please let me know.
$(function () {
$("a[rel]").overlay({
mask: 'lightgrey',
effect: 'apple',
onBeforeLoad: function () {
var wrap = this.getOverlay().find(".contentWrap");
wrap.load(this.getTrigger().attr("href"));
}
});
});
I have tried changing $("a[rel]") to $("a.testclass") and $("#test"), but no other identifier seems to work.

Make sure that you include jQuery Tools in your HTML, like so:
<script src="http://cdn.jquerytools.org/1.2.7/full/jquery.tools.min.js"></script>
That should make it work.

This is an official jQuery homepage. The API documentation is well organized. Search something about jQuery in this site.
overlay() doens't seem to be jQuery's default function. The function may be added like
$=jQuery;
$.fn.overlay=function(a, b, c){do something};
JavaScript eval("text") function also do the job you want (maybe).
