I've css style and jquery script at the same file. But my element in jquery is unable to read the css. Element that should take part are li,label, .selector, button. And also when I "Click Here" no alert come out.
Here is my jquery script:
$(document).ready(function(){
$.ajax({
//type: "POST",
url: "http://10.1.17.20:8040/services/getArticle",
success: function (data) {
var data2 = data.result.target;
btnTarget="<ul>";
for(var i=0; i<data2.length; i++){
btnTarget += "<li'><input id='"+data2[i].id+"' type='checkbox'>";
btnTarget += "<label for='"+data2[i].id+"'>"+data2[i].target_name+"</label></li>";
}
btnTarget += "</ul>";
btnTarget += "<button type='button' id='btnMenu'>Click Here</button>"
$(".selector").append(btnTarget);
},error: function (xhr, ajaxOptions, thrownError) {alert("ERROR:" + xhr.responseText+" - "+thrownError);}
});
});
$("document").on("click", "#btnMenu", function(){
alert("You Click");
});
var nbOptions = 8;
var angleStart = -360;
// jquery rotate animation
function rotate(li,d) {
$({d:angleStart}).animate({d:d}, {
step: function(now) {
$(li)
.css({ transform: 'rotate('+now+'deg)' })
.find('label')
.css({ transform: 'rotate('+(-now)+'deg)' });
}, duration: 0
});
}
// show / hide the options
function toggleOptions(s) {
$(s).toggleClass('open');
var li = $(s).find('li');
var deg = $(s).hasClass('half') ? 180/(li.length-1) : 360/li.length;
for(var i=0; i<li.length; i++) {
var d = $(s).hasClass('half') ? (i*deg)-90 : i*deg;
$(s).hasClass('open') ? rotate(li[i],d) : rotate(li[i],angleStart);
}
}
$(document).on('click','.selector button',function(e){
toggleOptions($(this).parent());
});
This is a part of html file.
<section class="content">
<!-- Your Page Content Here -->
<div class="row">
<!-- right column -->
<div class="col-md-12">
<!-- Horizontal Form -->
<div class="box box-info">
<!-- form start -->
<form class="form-horizontal">
<div class="box-body">

</div><!-- /.selector -->
</div>
</div><!-- /.box-body -->
</form>
</div><!-- /.box -->
</div><!--/.col (right) -->
</div><!-- /.row -->
</section>
Here also i put some css style. This is only few. The css style is too long
.selector button:hover { background: #3071a9; }
.selector button:focus { outline: none; }
.selector ul {
position: absolute;
list-style: none;
padding: 0;
margin: 0;
top: -20px;
right: -20px;
bottom: -20px;
left: -20px;
}
.selector li {
position: absolute;
width: 0;
height: 100%;
margin: 0 50%;
-webkit-transform: rotate(-360deg);
transition: all 0.8s ease-in-out;
}
.selector li input { display: none; }
Thanks in advance.
When you run this:
$("#btnMenu").on("click",function(){
alert("You Click");
});
btnMenu does not yet exist, so it isn't able to bind the eventHandler. You could do use event delegation like this:
$("body").on("click", "#btnMenu", function(){
alert("You Click");
});
and it will work.
For the css, my first thought is that it has to do with this:
<li'>
See the stray single quote? Probably messing stuff up down the line. Also, a lot of your jquery is outside of $(document).ready(function(){ so it may be running too early.
Try with this (cleaned up some single quotes:
$(document).ready(function(){
$.ajax({
//type: "POST",
url: "http://10.1.17.20:8040/services/getArticle",
success: function (data) {
var data2 = data.result.target;
btnTarget="<ul>";
for(var i=0; i<data2.length; i++){
btnTarget += "<li><input id="+data2[i].id+" type='checkbox'>";
btnTarget += "<label for="+data2[i].id+">"+data2[i].target_name+"</label></li>";
}
btnTarget += "</ul>";
btnTarget += "<button type='button' id='btnMenu'>Click Here</button>"
$(".selector").append(btnTarget);
},error: function (xhr, ajaxOptions, thrownError) {
//alert("ERROR:" + xhr.responseText+" - "+thrownError);
}
});
});
Also, you should get in the habit of doing this in case elements you are adding listeners to don't yet exist in the DOM:
$(document).on("click",$("#btnMenu"),function(){
alert("You Click");
});
Instead of:
$("#btnMenu").on("click",function(){
alert("You Click");
});

I'm trying to make a jquery code where you can show different images (1-3 different images) when you move the mouse around.
The images will be right beside the cursor, and they will only appear 1-3, not more than that. And each time the mouse moves, these images will change.
I currently have this as my html code,
<div class="mainbody">
<section class="container">
<div class="img_div">
</div>
</section>
</div>
And my jquery code looks like this:
let img_array = ['./img/awards_icon.png', './img/norinuri_icon.png'];
$("div.mainbody").mousemove(function(e) {
for(i=0; i<img_array.length; i++){
$('.img_div').append("<img src='" + img_array[i] +"'/>");
$('.img_div').fadeIn("5000");
$('.img_div').finish().fadeOut("5000");
$('.img_div').offset({
left: e.pageX,
top: e.pageY + 20
});
}
});
The 2 images that I have in my jquery array appears when the mouse moves, but instead of only having 2 images these images add continuously, without stopping.
So each time I would move my mouse, the images would continue to add infinitely.
I will add more images in the jquery array for sure,
but how should I have only two images added, and change these images as I move the mouse?
Use background-image
var imageArr=["https://www.w3schools.com/css/paper.gif","https://www.w3schools.com/css/gradient_bg.png","https://www.w3schools.com/css/img_tree.png"];
var count=0;
$( ".mainbody" ).mouseover(function() {
$( ".img_div" ).css('background-image', 'url("' + imageArr[count] + '")');
if(count == imageArr.length-1)
count=0;
else
count++;
});
.mainbody{
width: 500px;
height: 500px;
border:1px solid red;
}
.img_div{
width: 200px;
height: 200px;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="mainbody">
<section class="container">
<div class="img_div">
</div>
</section>
</div>
Here is working fiddle;
USING mousemove (to avoid the images to change so many times while mouse move I use timeout)
var imageArr=["https://www.w3schools.com/css/paper.gif","https://www.w3schools.com/css/gradient_bg.png","https://www.w3schools.com/css/img_tree.png"];
var count=0;
var timeoutid = 0;
function setImage() {
$( ".img_div" ).css('background-image', 'url("' + imageArr[count] + '")');
if(count == imageArr.length-1)
count=0;
else
count++;
}
$(".mainbody").mousemove(function() {
clearTimeout(timeoutid);
timeoutid = setTimeout(setImage, 100);
});
.mainbody{
width: 500px;
height: 500px;
border:1px solid red;
}
.img_div{
width: 200px;
height: 200px;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="mainbody">
<section class="container">
<div class="img_div">

화이팅!
I have created a working example for you. You can try it now:
<div class="mainbody">
<section class="container">
<div class="img_div">
hello
</div>
</section>
css
.mainbody {
border:1px solid red;
display:block;
height:1000px
}
jquery
let img_array = ['https://anotherjavaduke.files.wordpress.com/2018/08/avataaars-2.png',
'https://images2.minutemediacdn.com/image/upload/c_crop,h_1192,w_2121,x_0,y_111/f_auto,q_auto,w_1100/v1554921884/shape/mentalfloss/22461-istock-176984635.jpg'];
$("div.mainbody").on('mousemove', function(e) {
var i;
$('.img_div').html('')
for (i = 0; i < img_array.length; i++) {
console.log($('.img_div').has('img').length)
if ($('.img_div').has('img').length < img_array.length) {
$('.img_div').append("<img style='width:100px; height:100px' src='" + img_array[i] + "'/>");
$('.img_div').fadeIn("5000");
$('.img_div').finish().fadeOut("5000");
$('.img_div').offset({
left: e.pageX,
top: e.pageY + 20
});
}
}
});

I have the following page, which is a wikisearch page that queries multiple wikipidia pages for the search term. The page has the title and input box somewhere around the middle; however, when I click on the botton, the title slides up, and so the input box. But the input box slides all way up covering the title. I think!... how can I prevent the inputbox from covering the title? or make the title stays at the top of page? Thanks
$(document).ready(function() {
//bringing focus to search box
window.load = function() {
document.getElementById("search-box").focus();
};
//listener for search button
$("#search").click(function() {
$("#title").slideUp(3000);
// $("#title").css("text-align", "left");
search();
});
function search() {
//grabbing the id of search result div
var srchResult = document.getElementById("results");
//string entered by user for search
var searchStr = document.getElementById("search-box").value;
//replace space with _ in search query
searchStr = searchStr.replace(" ", "_");
console.log(searchStr);
$.ajax({
url: "https://en.wikipedia.org/w/api.php?action=query&list=search&srsearch=" + searchStr + "&prop=info&inprop=url&utf8=&format=json",
dataType: "jsonp",
success: function(response) {
if (response.query.searchinfo.totalhits === 0) {
showError(searchStr);
} else {
displayResults(response);
}
},
error: function() {
alert("Something went wrong.. <br>" +
"Try again!");
}
});
function displayResults(response) {
console.log(response.query);
var search = response.query.search;
var srchLength = response.query.search.length;
srchResult.innerHTML = "";
// console.log(srchResult.innerHTML);
//pulling title and searchbox to top
// $("#title").css("margin-top:", "10px !important");
for (var i = 0; i < srchLength; i++) {
srchResult.innerHTML += '<div class="output"><h4>' + search[i].title + ' </h4><p>' + search[i].snippet + '</p></div>';
}
}
return false;

function showError(search) {
srchResult.innerHTML = '<div class="output text-center"><h4>No Search result for: ' + search + '</h4></div>';
}
});

search-input {

<button id="search" class="btn btn-primary" onclick="#">Search</button>

</div>
Insted of using $('#title').slideUp(3000) try use $('#title').animate({'margin-top': '0'}, 3000);
Then the title will remain.
Also, you might want to remove onclick="#" from <button id="search" class="btn btn-primary" onclick="#">Search</button>
Example below.
$(document).ready(function() {

Add this to the h1 class
h1 {

Now let's say you needed something to then go on top of the header, you'd give that element's class a z-index of something higher than 1,000, so maybe 1,001! If you needed something to go behind, simply make it 999 or lower. Using 1,000 gives you a lot of free range in either direction (+/-) to work with.
I am a student and I am trying to start, pause and start a gif when a user clicks the gif, however I am stuck on how to add in this click function. I know that the the gif version of the object is .images.fixed_height.url and the still image is .images.fixed_height_still.url . If I try to append like below $(this) I get that images is undefined. How would I go by doing this? Currently 10 gifs show when you click the category. Thank you for any help in advance.

The difference between fixed_height and fixed_height_still will solve the problem. if you look closely the urls differ only by name_s.gif and name.gif.
So you can simply swap the two images to create a player. This will act like a play and stop. Not play and pause. But in a small gif I don't think pause really matter, stop and pause will look similar.
adding class name to the #photo
$("#photo").append('<img class="gif" src="' + response.data[i].images.fixed_height_still.url + '">');
event handler which will control play and stop
$('body').on('click', '.gif', function() {
var src = $(this).attr("src");
if($(this).hasClass('playing')){
//stop
$(this).attr('src', src.replace(/\.gif/i, "_s.gif"))
$(this).removeClass('playing');
} else {
//play
$(this).addClass('playing');
$(this).attr('src', src.replace(/\_s.gif/i, ".gif"))
}
});

you can use this jquery plugin http://rubentd.com/gifplayer/
<img class="gifplayer" src="media/banana.png" />
<script>
$('.gifplayer').gifplayer();

you can control like this
Use these methods to play and stop the player programatically
$('#banana').gifplayer('play');
$('#banana').gifplayer('stop');

I need to setup notification alerts for my website. I'm using this simple notification script. I have test it on my website like this.
<div id="notifications">
<div class="alert alert-danger" role="alert">
<a class="button close" style="padding-left: 10px;" href="#">×</a>
<i class="fa fa-info-circle "></i>

z-index: 9999;
bottom: 0;
margin-bottom: 22px;
margin-right: 15px;
max-width: 300px;
}

$( document ).ready(function() {
Notify = function(text, callback, close_callback, style) {
var time = '10000';
var $container = $('#notifications');
var icon = '<i class="fa fa-info-circle "></i>';
if (typeof style == 'undefined' ) style = 'warning'
var html = $('<div class="alert alert-' + style + ' hide">' + icon + " " + text + '</div>');
$('<a>',{
text: '×',
class: 'button close',
style: 'padding-left: 10px;',
href: '#',
click: function(e){
e.preventDefault()
close_callback && close_callback()
remove_notice()
}
}).prependTo(html)
$container.prepend(html)
html.removeClass('hide').hide().fadeIn('slow')
function remove_notice() {
html.stop().fadeOut('slow').remove()
}
var timer = setInterval(remove_notice, time);
$(html).hover(function(){

}, function(){
timer = setInterval(remove_notice, time);
});
html.on('click', function () {
clearInterval(timer)

});
}
});
The notification is appearing correctly because of css styling. But the script is not working. If I click close icon on notification, it's not closing. When I reload the page, it stays on the(auto closing is also not working) What ami I missing in my script?
Your requirements are a bit difficult to understand. You refer to the "notification" appearing correctly, but the only thing I see appearing is x Thanks in the bottom-right corner. However, that's not a notification, it's coming from your markup. It has no event associated with it, so nothing will happen when it is clicked.
Your main issue seems to be that you are defining something called Notify, but then not doing anything with it. To help you resolve this, please see the snippet below. It's probably not exactly what you want, but I think it's a lot closer.
$( document ).ready(function() {
Notify = function(text, callback, close_callback, style) {
var time = '10000';
var $container = $('#notifications');
var icon = '<i class="fa fa-info-circle "></i>';
if (typeof style == 'undefined' ) style = 'warning';
var html = $('<div class="alert alert-' + style + ' hide">' + icon + " " + text + '</div>');
$('<a>', {
text: '×',
class: 'button close',
style: 'padding-left: 10px;',
href: '#',
click: function(e) {
e.preventDefault();
e.stopPropagation();
close_callback();
remove_notice();
}
}).prependTo(html);
$container.prepend(html);
html.removeClass('hide').hide().fadeIn('slow');
function remove_notice() {
// html.stop().fadeOut('slow').remove()
html.fadeOut('slow', function() {
$(this).remove();
});
}
var timer = setInterval(remove_notice, time);
$(html).hover(function() {
setMessage('You hovered over me.');
clearInterval(timer);
}, function(){

// element is not currently being faded out

timer = setInterval(remove_notice, time);
}

my use case : create tab like experience. clicking on add button creates a (horz tab button) and a corresponding div, which is linked via onclick listener, dynamically.
problems :
on clicking add button, values from previous tabs are reset (which is obvious wrt to the way $tabs_prev & $menu_prev is populated) and
their respective js goes away (which I can't understand, why?)
a remove tab implementation (because the way I've coded these tabs, removing a tab and corresponding div isn't really simple, so, any clues in this direction, maybe?)

The reason why your javascript is disappearing is because resetting the innerHTML deletes the onclick handlers on the elements. Why: the original elements are destroyed, including references to events and new elements are created.
The code responsible for this:
$('#tabs').html($('#tabs').html() + main($('#template_tabs'), tabCount));
Please use jQuery's appending of an element by cloning the template tab:
$('#tabs').append($('#template_tabs').clone(true));
Append appends htmlstrings or elements to an parent element. It's a buffed up version of the documents native 'appendChild'.
clone clone the template element (makes a copy). You can do this in your function main and return it to the append function.
function main(tabCount)
{
var node = $('#template_tabs').clone(true));
//do things with the node, like setting an onclick handler, or id.
//example
node.setAttribute("id", "tab" + tabCount);
}
Removing can be done also:
function removeNode(node)
{
//provide a node via jQuery
//example: removeNode($("#tab2")) <-- now tab2 will be removed from the DOM.
node.remove();
}
