fullpage.js - adding links within tooltips - javascript

PROBLEM
I've tried adding a link to the navigational tooltips and, based on html, it should be working. However, no matter which tooltip I click, I am taken to the second section - even though the address indicated is correct and should be taking me across all sections.
for (var i = 0; i < $(SECTION_SEL).length; i++) {
var link = '';
if (options.anchors.length) {
link = options.anchors[i];
}
var li = '<li><span></span>';
// Only add tooltip if needed (defined by user)
var tooltip = options.navigationTooltips[i];
if (typeof tooltip !== 'undefined' && tooltip !== '') {
li += '<div class="' + SECTION_NAV_TOOLTIP + ' ' + options.navigationPosition + '">' + '' + tooltip + '</div>';
}
li += '</li>';
nav.find('ul').append(li);
}
I've tried putting the links into the init file as well, but that has the exact same effect.

Fullpage.js will ignore your link.
See line 1694
function sectionBulletHandler(e){
e.preventDefault();
var index = $(this).parent().index();
scrollPage($(SECTION_SEL).eq(index));
}
And line 567:
.on('click touchstart', SECTION_NAV_SEL + ' a', sectionBulletHandler)

Changing the CSS style for multiple check boxes not working

I have an application using firebase which looks like this:
The tick boxes to the right hand side of each 'Book', when clicked, sends the value of the firebase object into a string as shown below:
When clicking these tick boxes, I would like the style of the box and content to change so they turn blue. I have added this piece of code into the on click event:
function select(data, book, key) {
//What I added
document.getElementById('selectBook').style.color="blue";
document.getElementById('selectBook').style.borderColor="blue";
//
var selectBookRef = book;
document.getElementById('alltext').value += selectBookRef + ',';
}
However, this only turns the first box blue. No matter which check box I click, the first one just changes to blue and the rest stay grey.
Here is the JS code which creates the checkbox icons and the JS to highlight the selected check boxes.
function refreshUI(list) {
var lis = '';
var lis2 = '';
var lis3 = '';
//This generates the 3 columns on the application page
for (var i = 0; i < 10 && i < list.length; i++) {
lis += '<li style="width: 150px" data-key="' + list[i].key + '">' + list[i].book + genLinks(list[i].key, list[i].book) +'</li>';
};
for (var i = 10; i < 20 && i < list.length; i++) {
lis2 += '<li style="width: 150px" data-key="' + list[i].key + '">' + list[i].book + genLinks(list[i].key, list[i].book) +'</li>';
};
for (var i = 20; i < 30 && i < list.length; i++) {
lis3 += '<li style="width: 150px" data-key="' + list[i].key + '">' + list[i].book + genLinks(list[i].key, list[i].book) +'</li>';
};
document.getElementById('bookList').innerHTML = lis;
document.getElementById('bookList2').innerHTML = lis2;
document.getElementById('bookList3').innerHTML = lis3;
};
//This creates the 3 icons of delete, clear and select.
function genLinks(key, bkName) {
var links = '';
links += '<i id="deleteBook" class="material-icons">delete</i> ';
links += '<i id="removeBook" class="material-icons">clear</i> ';
links += '<i id="selectBook" onclick="functionSelected()" class="material-icons">check</i>';
return links;
};
function del(key, bkName) {
var deleteBookRef = buildEndPoint(key);
deleteBookRef.remove();
}
//This is the function to select and insert the data into the string as well as highlight each checkbox
function select(data, book, key) {
document.getElementById('selectBook').style.color="blue";
document.getElementById('selectBook').style.borderColor="blue";
var selectBookRef = book;
document.getElementById('alltext').value += selectBookRef + ',';
}
function buildEndPoint (key) {
return new Firebase('https://project04-167712.firebaseio.com/books/' + key);
}
bookList.on("value", function(snapshot) {
var data = snapshot.val();
var list = [];
for (var key in data) {
if (data.hasOwnProperty(key)) {
book = data[key].book ? data[key].book : '';
if (book.trim().length > 0) {
list.push({
book: book,
key: key
})
}
}
}
refreshUI(list);
});
If anybody can help it will be much appreciated.
Thanks,

The only thing I can see is that you are using the same id tags for multiple different objects on the same page. If you use it at more than one place, use a class! You should never have more than one of the same id because you will be facing a lot of repeating problems..

EventListener showing wrong target

I have the following JS code
var existingMenus = document.getElementsByClassName('multiSelectMenu');
for (var i = 0; i < existingMenus.length; i++) {
var existingMenu = existingMenus[i];
var existingMenuHTML = [];
var targetChildren = existingMenu.parentElement.nextElementSibling.children;
console.log(targetChildren)
// Here I'm adding +1 to the ID as it appears starting at zero with a styled checkbox does not work correctly
for (var x = 0; x < targetChildren.length; x++) {
if (targetChildren[x].selected) {
existingMenuHTML += '<li><input class="dropdown-input" type="checkbox" id="' + (x + 1) + '" data-label="' + targetChildren[x].textContent + '" checked="true"/><label class="multiLabel" for="' + (x +
1) + '"><span></span> ' + targetChildren[x].textContent + ' </label></li>';
} else {
existingMenuHTML += '<li><input class="dropdown-input" type="checkbox" id="' + (x + 1) + '" data-label="' + targetChildren[x].textContent + '"/><label class="multiLabel" for="' + (x + 1) +
'"><span></span> ' + targetChildren[x].textContent + ' </label></li>';
}
}
existingMenu.innerHTML += existingMenuHTML;
console.log(existingMenuHTML)
var inputs = existingMenu.children;
console.log(inputs);
for (var w = 0; w < inputs.length; w++) {
var input = inputs[w].children[0];
console.log(input);
input.addEventListener('click', function() {
console.log('--------------')
console.log(event)
var targetElement = event.target || event.srcElement;
console.log(targetElement);
var elementParent = targetElement.parentElement.parentElement.parentElement;
console.log(elementParent)
if (!elementParent.classList.contains('open')) {
elementParent.className += ' open';
}
var multiList = elementParent.nextSibling.querySelector('[value="' + targetElement.dataset.label + '"]');
console.log(multiList)
// Subtracting one to account for the plus one I added above
var inputId = targetElement.id - 1;
if (targetElement.checked == true) {
multiList.selected = "selcted";
} else {
multiList.selected = "";
}
console.log('--------------')
});
}
}
The code works correctly on the first instance of the multiPick but all others on page trigger the first multiSelectMenu items even though I was clicking on the 3rd multiSelectMenu on page.
Here is a screen shot of the console,
Here is a code pen, https://jsfiddle.net/6s3rc8d7/ When you click the 'label' and not the checkbox it has the same issue I am seeing.
The reason behind getting the different event.target in your fiddle is due to the below code snippet in your html.
<input class="dropdown-input" type="checkbox" id="1" data-label="English only">
<label class="multiLabel" for="1"><span></span> English only </label>
you can see that in the label element, you have the for attribute which contains the id of the input element. The functionality of for attribute is that the value of this identifies which form element a label is bound to. When you click on the label it will simulate the click event of the bounded element. This is why when you click the label , in your script the event.target is the input the label is bonded with.
More on for attribute you can read here. https://developer.mozilla.org/en-US/docs/Web/HTML/Element/label
I was able to rework the code and added the EventListener to the label instead of the checkbox.

How can I preserve fixed width display while hiding/showing span elements

I am working with some code from BioJS of which I'd like to extend the functionality. A BioJS object forms a sequence display by creating a separate span element for each letter and creating a break after x number of letters as such (simplified):
` var j=1;
for (var i=1; i <= a.length; i++) {
if( i % opt.numCols == 0) {
str += '<span class="sequence" id="' + this.getId() + '_' + i + '">' + a[i-1] + '</span>';
str += '<br/>';
j = 1;
} else {
str += '<span class="sequence" style="'+spaceStyle+'" id="' + this.getId() + '_' + i + '">' + a[i-1];
str += ( j % opt.numColsForSpace == 0)? ' ' : '';
str += (opt.spaceBetweenChars)? ' ' : '';
str += '</span>';
j++;
}
}`
This is nice for the built-in functionality of adding highlights to specific coordinates, which just uses jQuery to find the appropriate span and change the css. I've tried to take a similar approach with hiding elements by changing them to display:none, but unfortunately this leaves the line breaks behind, and thus big holes in the text. See a picture here:
Showing/Hiding
I'd like to know if there is another way I could create a similar display that would allow me to retain the fixed-width output after hiding the elements. Ideally I would still be able to use the highlight function, but I could also re-code that as well to work in a different way.
I found the source of the problem, which was that the javascript from BioJS was adding an inline style of whitespace: pre that was preventing the span elements from wrapping within the container. It was causing the containing element to only break on line breaks.

jQuery click event with parameter not working

I need some help. I am trying to iterate through some Json items, create some li's with some information from the items, but also attach click handlers for the li's, but with a value transmited as parameter.
The problem is that the last value of that parameter is set for or the li's in the list. From what i searched i understood that it has something to do with javascript closure, but can't seem to understand how to fix it.
I am using jQuery and here is the code:
for (var i = 0; i < items.length; i++)
{
// information that will be displayed for each video
var entry = items[i];
var title = entry.title;
var image = entry.thumbnail.hqDefault;
var id = entry.id;
var li = $("<li class='video-single'>");
li.append("<img src='" + image + "' alt='" + title + "'>");
li.append("<h4>" + title + "</h4>");
$(li).click(function() {
displayPopUp(id);
});
ul.append(li);
}
Could anyone please help me fix this code?
Best regards, Marius.
The issue is that JS is function scoped so the id within your closure is the last id from your for loop. To fix this use forEach so you run each iteration of your loop in a separate scope e.g.
items.forEach(function (el, i) {
// information that will be displayed for each video
var entry = items[i];
var title = entry.title;
var image = entry.thumbnail.hqDefault;
var id = entry.id;
var li = $("<li class='video-single'>");
li.append("<img src='" + image + "' alt='" + title + "'>");
li.append("<h4>" + title + "</h4>");
$(li).click(function() {
displayPopUp(id);
});
ul.append(li);
});
you need delegated event as elements are created dynamically, you can use class that is being added on li which is video-single:
$(document).on('click','.video-single',function() {
displayPopUp(id);
});
you can read about Delegated Events HERE
in order to bind an event to a dynamically added element you need to delegate it as below:
for (var i = 0; i < items.length; i++)
{
// information that will be displayed for each video
var entry = items[i];
var title = entry.title;
var image = entry.thumbnail.hqDefault;
var id = entry.id;
var li = $("<li class='video-single'>");
li.append("<img src='" + image + "' alt='" + title + "'>");
li.append("<h4>" + title + "</h4>");
$(document).bind('click',li,function() {
displayPopUp(id);
});
ul.append(li);
}

Using append() doesn't replace previous content

Firstly, I was trying to replace some contents in a div container using html() in Javascript on click. The problem using this approach is it only put the last value in the array.
So, I used append() instead. But it doesn't work like what I have expected. Well, it does append text in the for loops, but after a click, it just appends the content without removing the previous content like what html() does.
Here is how I implement it:
<div id="events-content"></div>
// using Responsive Calendar js
onMonthChange: function(events) {
for (var eventsDate in options.events) {
if (eventsDate.indexOf(monthKey) != -1) {
var monthEvents = options.events[eventsDate];
for(i = 0; i < options.events[eventsDate].dayEvents.length; i++) {
$('#events-content').append(
'<p><b>' + eventsDate + ':</b> ' +
monthEvents.dayEvents[i].name + '<br/></p>');
}
}
}
},
...
How do I replace the previous appended text using Javascript?
I'm using this in Responsive Calendar JS
well, you could do something like this...
Prepare all the markup in the loop.
var html = "";
for(i = 0; i < options.events[eventsDate].dayEvents.length; i++) {
html += '<p><b>' + eventsDate + ':</b> ' +
monthEvents.dayEvents[i].name + '<br/></p>';
}
$('#events-content').html(html);
Clear the html before the for loop/append mechanism.
Use .empty()
onMonthChange: function(events) {
$('#events-content').empty() //or $('#events-content').html('');
for (var eventsDate in options.events) {
if (eventsDate.indexOf(monthKey) != -1) {
var monthEvents = options.events[eventsDate];
for(i = 0; i < options.events[eventsDate].dayEvents.length; i++) {
$('#events-content').append(
'<p><b>' + eventsDate + ':</b> ' +
monthEvents.dayEvents[i].name + '<br/></p>');
}
}
}
},
