I have tried changing the keyup part of the code to a button and I have also tried some code to get the draggable element to store its position in the cookie but to no avail. When I change the empty tag to ready it repeats the previous lines every time. Any help would be much appreciated.

I think you shouldn't remove all your <d> and start over every time. I have made some changes in the code to reuse the old <d> so that it's position is preserved
$(document).ready(function () {
$("textarea").keyup(splitLine);
function splitLine() {
//$("#opt").empty();
var lines = $("textarea").val().split(/\n/g);
for (var i = 0; i < lines.length; i++) {
var ele;
if ($("d:eq(" + i + ")").get(0)) {
ele = $("d:eq(" + i + ")");
ele.html(lines[i]);
} else {
ele = $("<d>");
ele.html(lines[i]);
$("#opt").append($(ele).draggable());
}
}
}

As topic, how can I remove the quote in the picuture below or get the img element from this?
(https://i.stack.imgur.com/kdPAP.png)
I m new to javascript and start making an image slider that can pop up a window while clicked to the image.
I cloned the li object which is clicked, and try to open it in the new window, it do work but how can I get the img only without the li?

.innerHTML is a string. You don't want to append a string, but the element. So change this:
var koronaitemu=this.cloneNode(true);
var koronimeji=koronaitemu.innerHTML;
kakudaigazou.append(koronimeji);
...to this:
var koronimeji=this.querySelector("img").cloneNode();
kakudaigazou.append(koronimeji);

JavaScript closure inside loops – simple practical example
(44 answers)
Closed 5 years ago.
I want to create 1 div container every x second. And I want to do this n times.
So I started creating this
$(document).ready(function() {
for (var i = 0; i < 5; i++) {
createEle(i);
}
});
function createEle(value) {
var d = $("<div></div>");
d.addClass("d");
d.html(value);
$("#container").append(d);
}
.d {
height: 20px;
color: white;
background: red;
margin-bottom: 20px;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="container">
</div>
this works fine. But I want to integrate the time interval.
$(document).ready(function() {
for (var i = 0; i < 5; i++) {
setTimeout(function() {
createEle(i);
}, i * 1000);
}
});
function createEle(value) {
var d = $("<div></div>");
d.addClass("d");
d.html(value);
$("#container").append(d);
}
.d {
height: 20px;
color: white;
background: red;
margin-bottom: 20px;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="container">
</div>
As you can see in the second example, I always get the wrong value because it passes in the wrong index value.
How can I fix that?
Replace var with let.
for (let i = 0; i < 5; i++) {
Demo
$(document).ready(function() {
for (let i = 0; i < 5; i++) {
setTimeout(function() {
createEle(i);
}, i * 1000);
}
});
function createEle(value) {
var d = $("<div></div>");
d.addClass("d");
d.html(value);
$("#container").append(d);
}
.d {
height: 20px;
color: white;
background: red;
margin-bottom: 20px;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="container">
</div>
Reason
var doesn't let go of the bindings of the parent lexical-environment hence its hoisted value is retained in the asynchronous callback handler (of setTimeout), however let doesn't hold on to the bindings of any lexical-environment other than its own current one.
please update your code. no need of for loop.
var i=1;
$(document).ready(function() {
setInterval(function() {
createEle(i);
}, i * 1000);
});
function createEle(value) {
var d = $("<div></div>");
d.addClass("d");
d.html(value);
$("#container").append(d);
i++;
}
Loop will completely executed before the first setTimeout runs. So the value of the i will be 5
Treat setTimeout and setInterval as a asynchronous function.
$(document).ready(function() {
var i = 0;
var tmer = setInterval(function() {
createEle(i);
i = i + 1;
if(i==5)
clearInterval(tmer);
}, 1000);
});
function createEle(value) {
var d = $("<div></div>");
d.addClass("d");
d.html(value);
$("#container").append(d);
}
.d {
height: 20px;
color: white;
background: red;
margin-bottom: 20px;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="container">
</div>
I have an input button with a centered text. Text length is changing dynamically with a js (dots animation), that causes text moving inside the button.
Strict aligning with padding doesn't suit because the text in the button will be used in different languages and will have different lenghts. Need some versatile solution. The main text should be centered and the dots should be aligned left to the end of the main text.
var dots = 0;
$(document).ready(function() {
$('#payDots').on('click', function() {
$(this).attr('disabled', 'disabled');
setInterval(type, 600);
})
});
function type() {
var dot = '.';
if(dots < 3) {
$('#payDots').val('processing' + dot.repeat(dots));
dots++;
}
else {
$('#payDots').val('processing');
dots = 0;
}
}
<input id="payDots" type="button" value="Pay" class="button">
.button{
text-align: center;
width: 300px;
font-size: 20px;
}
https://jsfiddle.net/v8g4rfsw/1/ (button should be pressed)
The easiest as this is a value and extra elements can't be inserted, would be to just use leading spaces to make the text appear as it's always centered.
This uses the plugin I wrote for your previous question
$.fn.dots = function(time, dots) {
return this.each(function(i,el) {
clearInterval( $(el).data('dots') );
if ( time !== 0 ) {
var d = 0;
$(el).data('dots', setInterval(function() {
$(el).val(function(_,v) {
if (d < dots) {
d++;
return ' ' + v + '.';
} else {
d = 0;
return v.substring(dots, v.length - dots)
}
})
}, time));
}
});
}
$(document).ready(function() {
$('#payDots').on('click', function() {
$(this).val('Proccessing').prop('disabled',true).dots(600, 3);
});
});
.button{
text-align: center;
width: 300px;
font-size: 20px;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input id="payDots" type="button" value="Pay" class="button">

This is my situation:
I have a image gallery with 10 images visible on the main page and a pagination bar. The images came from a for loop iteration over a json file. That's no problem, they are just there ;-)
Something like:
for i=0; i <10; i++
create div with styles and images[i].image;
My question is:
I want to display the next 10 images on page 2, so when you click on page 2, it counts from 11 to 20.
I found the jQuery 'Jpaginate'-plugin...
Can i accomplish that with this plugin?
Could someone explain me in the way i have to thing with Vars, Counts, Objects??
Thanks and kind regards,
Mike
I have made you an example on how you can approach this. I'm not saying it is bugproof, but it's the concept that matters. You might find some inspiration and maybe reach your goal.
var imgSrc = "https://s-media-cache-ak0.pinimg.com/236x/36/a5/7b/36a57b0f0ab16e885fcc230addb695c2.jpg";
var json = [];
for (var i = 0; i < 36; i++)
json.push({
Title: "Title " + (i + 1),
Source: imgSrc
});
/*
Just for ease, I'm creating an array with 36 objects (3x3 gallery)
so 9 images per page
*/
var pageLimit = 9;
var page = 1;
showImages();
$("#btnPrevious").click(function() {
if (pageLimit <= 9) {
pageLimit = 9;
page = 1;
} else {
page--;
pageLimit -= 9;
}
showImages();
});
$("#btnNext").click(function() {
if (pageLimit >= json.length) {
pageLimit = json.length;
} else {
page++;
pageLimit += 9;
}
showImages();
});
function showImages() {
$(".images").empty();
for (var i = pageLimit - 9; i < pageLimit; i++) {
var template = $("<div></div>").addClass("template");
var img = $("<img>");
img.attr("src", json[i].Source);
img.attr("alt", json[i].Title);
var br = $("<br/>");
var title = $("<span></span>").html(json[i].Title);
template.append(img).append(br).append(title);
$(".images").append(template);
}
$("#page").html("Page " + page);
}
.gallery {
width: 100%;
height: 500px;
border: 1px solid black;
background-color: lightgray;
text-align: center;
}
.images {
width: 90%;
margin: 0 auto;
height: 100%;
margin-bottom: 15px;
}
img {
height: auto;
width: 33%;
margin: 20px 5px;
}
.template {
float: left;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="gallery">
<div class="images"></div>
<button id="btnPrevious">
< Previous
</button>
<span id="page"></span>
<button id="btnNext">
> Next
</button>
</div>
Don't mind the CSS, because I suck at that (lol). It was based on the space I had on jsFiddle, but looking at it now (on full page or just the area the snippet provides) it looks awful. If a CSS guru could fix this .. Question in a question?
You can create your own pagination plugin.
You must store current page somewhere and modify your factory.
Something like: for i=current_page * count_per_page; i < count_per_page * (current_page + 1); i++ create div with styles and images[i].image;
I'm trying to make appear text in Javascript.
That's my code :
HTML :
<div id="t1">Ecologie</div>
<div id="t2">Planète</div>
<div id="t3">BIO</div>
<div id="t4">Responsable</div>
<div id="t5">Changement</div>
<div id="t6">Durable</div>
<script type="text/javascript">var mytimeout = setTimeout(DisplayElem(), 2000)
</script>
CSS :
#t1
{
position: absolute;
color: green;
font-size: 50px;
top: 50%;
left: 13%;
display: none;
}
#t2
{
position: absolute;
color: green;
font-size: 60px;
top: 40%;
left: 70%;
display: none;
}
and Javascript :
function Display (elem) {
elem.style.display = block;
}
var compteur = 0;
function DisplayElem()
{
compteur += 1;
var id = 't' + compteur;
elem = document.getElementById(id);
Display(elem);
mytimeout = setTimeout(DisplayElem(), 2000)
if(compteur == 6)
{
window.clearTimeout(mytimeout);
}
}
I got this error : Uncaught ReferenceError: block is not defined
on my line :elem.style.display = block;
When i open my page i want all of my div invisible. But after a few second i would like to have on who appear, and the next one, and the next one...
Thank you
Here is your complete working code:
var compteur = 1;
function Display (elem) {
elem.style.display = 'block';
}
function DisplayElem()
{
var id = 't' + compteur;
elem = document.getElementById(id);
Display(elem);
compteur += 1;
if (compteur <= 6)
setTimeout(DisplayElem, 2000);
}
DisplayElem();
See the DEMO here
You have forgotten the delimiters around the string block:
function Display (elem) {
elem.style.display = 'block';
}
Side note: Instead of setting the timeout the last time and then removing it, just skip setting it:
if (compteur < 6) {
mytimeout = setTimeout(DisplayElem(), 2000)
}
