How to sync texts and photos in bootstrap? - javascript

I have a bootstrap site which has 3 photos in a slideshow. The function which does that is:
$(function () {
$.vegas('slideshow', {
backgrounds: [{
src: 'img/ph1.jpg', fade: 0, delay: 5000, //fade: 1000, delay: 9000,
}, {
src: 'img/ph2.jpg', fade: 0, delay: 5000,
}, {
src: 'img/ph3.jpg', fade: 0, delay: 5000,
},]
})('overlay', {});
});
What I want to do is to associate text for each photo. For example: for ph1.jpg to have "text1", for ph2.jpg to have "text2", and so on.
I tried to add a carousel in my HTML but the text and the photo are not synchronized (even if they have the same delay). I also tried to modify this JS so to be able to add some text in the above function.
What can I do to get them sync the photos and the text?

Try better to put your images in a css file and from there to put the text for each other.

You may try below code which rely on vegaswalk event callback.
vegaswalk event gets triggered whenever Vegas changes the slide. It can be utilized as follows:
var textArray = [
"text1 for ph1.jpg",
"text2 for ph2.jpg",
"text3 for ph3.jpg"
];
$("body").on('vegaswalk', function (e, index, slideSettings) {
var currentText = textArray[index];
alert(currentText);
//write here code to set this text in some div present on Page
//OR
//write code to move the slide of text carousel as per current index of slideshow
});

How to wait 1 second to move another slider after click using swiperjs api?

I am having difficulty to figure out how to wait or delay slider about 1 second before move to another slider. The below is JavaScript. I am not sharing the html code because its too lengthy and my question will look messy. I hope some of you have idea. I really appreciate your help.
Js code
var swiper = new Swiper('.swiper-container', {
autoHeight: true, //enable auto height
mousewheelControl: false,
touchRatio: 0,
allowTouchMove: false,
shortSwipes: false,
speed:2000,
navigation: {
nextEl: '.swiper-button-next',
},
});
I am having difficulty to figure out how to wait or delay [...] about 1 second
If you wish to delay script execution, you need setTimeout.
Anatomy of setTimeout:
setTimeout( [CALLBACK FUNCTION], [TIME DELAY] );
Working Example:
const myButton = document.getElementsByTagName('button')[0];
const clickButton = () => {
setTimeout(() => {
let myParagraph = document.createElement('p');
myParagraph.textContent = 'You clicked the button.';
document.body.appendChild(myParagraph);
}, 1000);
}
myButton.addEventListener('click', clickButton, false);
<button type="button">Click Me</button>
<p>A second after you click the button above, more text will appear...</p>

Trying to randomize a news ticker interval in jQuery

I have a jQuery-based scrolling news ticker that uses a set interval in milliseconds to control the delay between the reveal of each new section of text. I'd like to randomize the delay so that it more closely mimics the way a realtime news feed would look.
I've tried experimenting with some Math.random javascript where the newsTickerInterval parameter is, but JS is not my native language and I'm having trouble making it work.
Here's the jQuery function my scroller uses to config the display:
$(function () {
$(".demo2").bootstrapNews({
newsPerPage: 4,
autoplay: true,
pauseOnHover: true,
navigation: false,
direction: 'down',
newsTickerInterval: 3000,
onToDo: function () {
//console.log(this);
}
});
});
Any hints or suggestions would be greatly appreciated!
Instead of using newsTickerInterval, make a function getNewsTickerDelay that generates a random delay interval and call it using a setTimeout whenever needed.
$(function () {
$(".demo2").bootstrapNews({
newsPerPage: 4,
autoplay: true,
pauseOnHover: true,
navigation: false,
direction: 'down',
getNewsTickerDelay: function() {
var minimumInterval = 2000;
var maximumInterval = 5000;
var additionalInterval = Math.floor(
Math.random() * (maximumInterval - minimumInterval)
);
return minimumInterval + additionalInterval;
},
onToDo: function () {
//console.log(this);
}
});
});
So, every time your timeout is called, set another one with a random delay using getNewsTickerDelay
--EDIT--
As pointed out by #Barmar, you might need to tweak the implementation of the plugin in your case and implement its internal animate method to use your defined random interval instead of a fixed value. You'll just need to replace the self.options.newsTickerInterval in that plugin's JS to self.options.getNewsTickerDelay(). That is if you are willing to mutate the plugin's implementation.

Ion.RangeSlider color from middle

I'm trying to use Ion.RangeSlider to make a slider where the color starts from the center and goes in the direction of the slider control until it hits the slider control. Right now, this is what I have:
Instead, I would like the color to go from the center of the slider to the slider control.
How can I make the RangeSlider work like that so that the color starts from the middle (as shown above)?
EDIT:
I looked at this question, but it deals with sliders with two controls instead one.
EDIT 1:
setup.js:
jQuery(document).ready(function($){
$(".slider").each(function() {
console.log($(this).attr("id"));
$(this).ionRangeSlider({
type: $(this).attr("data-slider_type"),
grid: $(this).attr("data-slider_grid"),
min: $(this).attr("data-slider_min"),
max: $(this).attr("data-slider_max"),
prefix: $(this).attr("data-slider_prefix")+" ",
postfix: " " + $(this).attr("data-slider_suffix"),
step: $(this).attr("data-slider_stepper"),
from: $(this).attr("data-slider_from")
});
$(this).on("change", function () {
var $this = $(this),
value = $this.prop("value").split(";");
});
});
});
Use: https://github.com/jordansoltman/ion.rangeSlider with has the additional boolean option: fixMiddle. For example:
$(".slider").ionRangeSlider({
fixMiddle: true,
...
});
Note: use ion.rangeSlider.js as ion.rangeSlider.min.js has not been updated.

How to dynamically create multiple jQuery sliders?

I am working on a WordPress site that turns a custom post type into a slider on a page. I am using Sequence.js for my slider and I can manually create multiple sliders no problem with the following:
//sequence slider options to be used by slider1
var options0 = {
sartingFrameID: 1,
cycle: true,
autoPlay: false,
nextButton: '.next0',
prevButton: '.prev0',
fallback: {
theme: "fade",
speed: 100
}
}
//slider1
var sequence0 = $(".slideContainer0").sequence(options0).data("sequence");
//sequence slider options to be used by slider2
var options1 = {
sartingFrameID: 1,
cycle: true,
autoPlay: false,
nextButton: '.next1',
prevButton: '.prev1',
fallback: {
theme: "fade",
speed: 100
}
}
//slider2
var sequence1 = $(".slideContainer1").sequence(options1).data("sequence");
How can I streamline this? And also make it dynamic so a slider is created for each post that is made? Any help would be greatly appreciated.
edited - added working answer
I used the answer from Cymen below for the first part by turning the options output into a function and simply calling the function with a counter for each sequence instance. Then used the second part of his answer to initialize each sequence slider and it works a treat.
This is what I have working now:
function options(number) {
return {
startingFrameID: 1,
cycle: true,
autoPlay: false,
nextButton: '.next' + number,
prevButton: '.prev' + number,
fallback: {
theme: "fade",
speed: 100
}
};
}
var count = 0;
$('.slideContainer').each(function() {
var sequence = $(this);
sequence.sequence(options(count)).data('sequence');
count++;
});
I haven't used sequence but from your post I am guessing you want to be able to recreate the options object with an increment of the number. So you could do something like this:
function options(number) {
return {
startingFrameID: 1,
cycle: true,
autoPlay: false,
nextButton: '.next' + number,
prevButton: '.prev' + number,
fallback: {
theme: "fade",
speed: 100
}
};
}
Then use it like so:
$(target).sequence(options(0)).data("sequence");
Or in your specific example:
//slider1
var sequence0 = $(".slideContainer0").sequence(options(0)).data("sequence");
//slider2
var sequence1 = $(".slideContainer1").sequence(options(1)).data("sequence")
And to do what you are talking about how about giving all the sequences the same class like say custom-sequence and then do something like this:
var count = 0;
$('.custom-sequence').each(function() {
var sequence = $(this);
sequence.sequence(options(count)).data('sequence');
count++;
});
That may or may not work -- it isn't quite clear to me what the .data('sequence') is doing.

Call jQuery function in a loop with different parameters

I am trying to create multiple carousels in one page following this example.
I am creating my carousels in a foreach loop, and I assign to each carousel the names c0, c1, c2, etc. (Each carousel is a <div>)
Now, in order to run the script according to the example, I should run in on each carousel separately.
For example:
<script type="text/javascript">
$(document).ready(function() {
$('#c0').jsCarousel({ onthumbnailclick: function(src) { alert(src); }, autoscroll: true, masked: false, itemstodisplay: 3, orientation: 'v' });
$('#c1').jsCarousel({ onthumbnailclick: function(src) { alert(src); }, autoscroll: false, masked: false, itemstodisplay: 5, orientation: 'h' });
$('#c2').jsCarousel({ onthumbnailclick: function(src) { alert(src); }, autoscroll: true, masked: true, itemstodisplay: 5, orientation: 'h' });
});
</script>
Since my carousels are created in a foreach loop, I cannot know how many of them I will have, so I tried to call the function in a for loop:
for (int i = 0; i < counter; i++)
{
string cNum = "#c" + i.ToString();%>
<script type="text/javascript">
$(document).ready(function() {
$(cNum).jsCarousel({ onthumbnailclick: function(src) { alert(src); }, autoscroll: true });
});
</script>
<%} %>
I checked, and the cNum values are okay, it gets the values #c0, #c1, etc. but it can't recognize it as an equivalent to '#c0' etc. that were there initially.
How can I insert dynamic carousel names into the function?
Instead of doing that, just give each div a class. Like this:
<div class="someClassThatIKnowIsACarousel">
Then you don't need a loop:
$(".someClassThatIKnowIsACarousel").jsCarousel({ onthumbnailclick: function(src) { alert(src); }, autoscroll: true });
The problem in your code is that cNum inside your dynamically generated JavaScript section isn't interpreted as an ASP variable. You could fix that with something like $('<% cNum %>') (also note the JavaScript quotes, without get you would get $(#c0), which is erroneous).
However, your approach is wrong, please avoid the best you can mixing server/client code like that.
As aquinas already pointed out, the best solution is to add a class to the divs:
HTML:
<div class="carousel">
JavaScript:
$('div.carousel').jsCarousel({ ... });
