How to stop mousedown event on reaching specific number in increment - javascript

How can I break, kill or stop mousedown event when hits an specific benchmark?
For example in following code, I want to disable the Key and event when the temp hits 30
$(document).ready(function() {
var temp = 0;
var to = null;
var iv = null;
$("#ClickMe").on("mousedown", function() {
temp++;
$("#Temp").html(temp);
to = setTimeout(function() {
iv = setInterval(function() {
temp++;
$("#Temp").html(temp);
}, 75);
}, 500);
}).on("mouseup mouseleave", function() {
clearTimeout(to);
clearInterval(iv);
});
});
div {
margin: 10px;
padding: 26px;
background-color: yellow;
text-align: center;
border-radius: 10px;
max-width: 40px;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<button id="ClickMe">CLICK ME</button>
<div id="Temp">0</div>

ok, complete answer, with code...
$(document).ready(function() {
var temp = 0;
var to = null;
var iv = null;
$("#ClickMe")
.on("mousedown", function() {
temp++;
$("#Temp").html(temp);
to = setTimeout(function() {
iv = setInterval(moreClick, 75);
}, 500);
})
.on("mouseup mouseleave", function() {
clearTimeout(to);
clearInterval(iv);
test_stopClick();
});
function moreClick() {
$("#Temp").html(++temp);
test_stopClick();
}
function test_stopClick() {
if (temp >= 30 ) {
clearTimeout(to);
clearInterval(iv);
$("#ClickMe")
.off("mousedown mouseup mouseleave")
.prop('disabled', true);
}
}
});
div {
margin: 10px;
padding: 26px;
background-color: yellow;
text-align: center;
border-radius: 10px;
max-width: 40px;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<button id="ClickMe">CLICK ME</button>
<div id="Temp">0</div>

Add an if statement, and then use jQuery's .off() method:
$(document).ready(function() {
var temp = 0;
var to = null;
var iv = null;
$("#ClickMe").on("mousedown", function() {
if (temp < 30) {
temp++;
$("#Temp").html(temp);
to = setTimeout(function() {
iv = setInterval(function() {
temp++;
$("#Temp").html(temp);
}, 75);
}, 500);
} else {
$("#ClickMe").off("mousedown");
}
}).on("mouseup mouseleave", function() {
clearTimeout(to);
clearInterval(iv);
});
});
div {
margin: 10px;
padding: 26px;
background-color: yellow;
text-align: center;
border-radius: 10px;
max-width: 40px;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<button id="ClickMe">CLICK ME</button>
<div id="Temp">0</div>

jQuery animation should pause on hover

This is my code:
var animationDuration = 3000;
var firstText = $(".text:first-child");
var currentText = firstText;
function changeText() {
$(currentText).css("display", "none");
var NextText = currentText.next(".text");
if (!NextText.length) NextText = firstText;
$(NextText).css("display", "block");
currentText = NextText;
}
var loopTimer = setInterval(changeText, animationDuration);
$('.animatedText').hover(function(e) {
clearInterval(loopTimer);
}, function(e) {
changeText();
loopTimer = setInterval(changeText, animationDuration);
})
.text {
display: none;
white-space: pre-wrap;
font-size: 30px;
cursor: default;
}
.text:nth-child(1) {
display: block;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<section class="animatedText">
<div class="text">One</div>
<div class="text">Two</div>
<div class="text">Three</div>
<div class="text">Four</div>
</section>
Currently, the animation seems to pause on hover, but if you unhover, you can see that always abruptly the next div gets shown. So it is not really a "pause", it just stops and shows the next div then. The duration time gets lost.
How is it possible to fix that?
Would be very thankful for help!
You made a small mistake by running function changeText() for the reverse hover. Here:
function(e) {
changeText();
loopTimer = setInterval(changeText, animationDuration);
})
Thus a double start of the function is obtained.
Just remove this function run and you will get the desired result. Because you already run this function changeText():
loopTimer = setInterval(changeText, animationDuration);
var animationDuration = 3000;
var firstText = $(".text:first-child");
var currentText = firstText;
function changeText() {
$(currentText).css("display", "none");
var NextText = currentText.next(".text");
if (!NextText.length) NextText = firstText;
$(NextText).css("display", "block");
currentText = NextText;
}
var loopTimer = setInterval(changeText, animationDuration);
$('.animatedText').hover(function(e) {
clearInterval(loopTimer);
}, function(e) {
loopTimer = setInterval(changeText, animationDuration);
})
.text {
display: none;
white-space: pre-wrap;
font-size: 30px;
cursor: default;
}
.text:nth-child(1) {
display: block;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<section class="animatedText">
<div class="text">One</div>
<div class="text">Two</div>
<div class="text">Three</div>
<div class="text">Four</div>
</section>
Something like this?
$(function() {
var counter = 0,
divs = $(".text"),
divsN = divs.length,
intv;
function showDiv() {
divs.hide().eq(counter++ % divsN).show();
}
showDiv();
function auto() {
clearInterval(intv);
intv = setInterval(function() {
showDiv();
}, 2000);
}
auto();
divs.on("mouseenter mouseleave", function(e) {
var evt = e.type == "mouseenter" ? clearInterval(intv) : auto();
});
});
.text {
display: none;
white-space: pre-wrap;
font-size: 30px;
cursor: default;
}
.text:nth-child(1) {
display: block;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<section class="animatedText">
<div class="text">One</div>

jQuery - hide input if maxTags reached using tags.js

Using the tags() function, there is a parameter for maximum number of tags (maxTags) you can enter into each input.
I need to hide(); the tags-input when maxTags = 2 and then
show(); when the tag is removed / not at the max.
maxTags :1 isn't working but it should be. Only 2 or more is acceptable. I tried debugging the max tags parameter but couldn't find out why maxTags: 1 is
unacceptable.
How can I change the function to allow maxTags: 1 and also show/hide the tag-input when maxTags is reached?
// max tags in tags() function:
if (opts.maxTags) {
if ($self.val().split(",").length == opts.maxTags) {
otherCheck = false;
$input.val("");
$next.val("");
}
}
// Calling the tags() function:
$("#" + formId)
.find(".input--proj")
.tags({
unique: true,
maxTags: 2
})
.autofill({

});
(function($) {
$.fn.tags = function(opts) {
var selector = this.selector;
//console.log("selector",selector);
// updates the original input
function update($original) {
var all = [];
var list = $original.closest(".tags-wrapper").find("li.tag span").each(function() {
all.push($(this).text());
});
all = all.join(",");
$original.val(all);
}
return this.each(function() {
var self = this,
$self = $(this),
$wrapper = $("<div class='tags-wrapper'><ul></ul></div");
tags = $self.val(),
tagsArray = tags.split(","),
$ul = $wrapper.find("ul");
// make sure have opts
if (!opts) opts = {};
opts.maxSize = 50;
// add tags to start
tagsArray.forEach(function(tag) {
if (tag) {
$ul.append("<li class='tag'><span>" + tag + "</span><a href='#'>x</a></li>");
}
});

I've added code to test maxTags value from 1 to 3. Just replace it.
Removed a tag. Show input.
$wrapper.on("click", "li.tag a", function(e) {
e.preventDefault();
$(this).closest("li").remove();
$self.trigger("tagRemove", $(this).closest("li").find("span").text());
update($self);
$("[data-search]").keyup();
$input.show(); // show input on remove
});
If string has no content, return 0. Else use split to find number of elements.
if (opts.maxTags) {
var len = $self.val();
len = len.trim().length > 0 ? len.split(',').length : 0;
(function($) {
$.fn.tags = function(opts) {

Make navigation clickable in fullpage script

I have a simple project based on one variation of fullpage script. Everything works perfect except for one annoying thing - I can't understand how to make my right navigation bullets clickable (to an appropriate section). My js knowledge is not too good at the moment so I'd really appreciate any help, guys. Thanks!
$.fullPage = function(option) {
var defaultOpt = {
box: "#fullPageBox", // 滚屏页父元素
page: ".fullPage", // 滚屏页面
index: true, // 是否显示索引
duration: 1000, // 动画时间
direction: "vertical", // 滚屏方向 horizontal or vertical
loop: true // 是否循环
},
This = this,
index = 0,
over = true;
this.option = $.extend({}, defaultOpt, option || {});
this.box = $(this.option.box);
this.pages = $(this.option.page);
this.duration = this.option.duration;
// 绑定鼠标滚轮事件
$(document).on("mousewheel DOMMouseScroll", function(ev) {
var dir = ev.originalEvent.wheelDelta || -ev.originalEvent.detail;
if (over === false) return;
dir < 0 ? nextPage() : prevPage();
});
if (this.option.index) {
initPagination();
};
function initPagination() {
var oUl = $("<ul id='fullPageIndex'></ul>"),
liStr = "";
for (var i = 0, len = This.pages.length; i < len; i++) {
liStr += "<li></li>";
};
$(document.body).append(oUl.append($(liStr)));
$("#fullPageIndex li").eq(index).addClass("active").siblings().removeClass("active");
};
function nextPage() {
if (index < This.pages.length - 1) {
index++;
} else {
index = 0;
}
scrollPage(index, This.pages.eq(index).position());
};
function prevPage() {
if (index === 0) {
index = This.pages.length - 1;
} else {
index--;
}
scrollPage(index, This.pages.eq(index).position());
};
function scrollPage(index, position) {
over = false;
var cssStr = This.option.direction === "vertical" ? {
top: -position.top
} : {
left: -position.left
};
This.box.animate(cssStr, This.duration, function() {
over = true;
})
$("#fullPageIndex li").eq(index).addClass("active").siblings().removeClass("active");

Add an id attribute to you divs and add an anchor to the list elements that navigate to the desired sections. As follows:
<body>
<div class="pageBox">
<div class="main" id="fullPageBox">
<div id="section1" class="fullPage bg1">jQuery fullPage.js</div>
<div id="section2" class="fullPage bg2">Section 2</div>
<div id="section3" class="fullPage bg3">Section 3</div>
<div id="section4" class="fullPage bg4">Section 4</div>
<div id="section5" class="fullPage bg5">Section 5</div>
</div>
</div>
<script>
$.fullPage();
</script>
</body>
Update your js where you render the list items to look like this:
function initPagination() {
var oUl = $("<ul id='fullPageIndex'></ul>"),
liStr = "";
for (var i = 0, len = This.pages.length; i <= len; i++) {
var sectionNum = i + 1;
liStr += '<li></li>';
};
$(document.body).append(oUl.append($(liStr)));
$("#fullPageIndex li").eq(index).addClass("active").siblings().removeClass("active");
};

EDIT:
Since you asked for a smooth scroll as well you could add this to your JS:
$('a[href*=#]:not([href=#])').click(function() {
if (location.pathname.replace(/^\//,'') == this.pathname.replace(/^\//,'')
|| location.hostname == this.hostname) {
var target = $(this.hash);
target = target.length ? target : $('[name=' + this.hash.slice(1) +']');
if (target.length) {
$('html,body').animate({
scrollTop: target.offset().top
}, 1000);
return false;
}
}
});
Source for the snippet can be found on this page.
there is some mistake in your script.
First, remove below code from your HTML file:
<script>
fullPage();
</script>
Second is, you've created wrong function (method) define. I'am replace $.fullpage = function(option) { with var fullpage = function(options) {
and for the last is: since we have removed your fullpage() initiator, so we need to call this method again. for example at end line of your JS file,
P.S:
In Javascript you can create function in several ways. See https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Functions for more detail.
See fixed code below:
var fullPage = function(option) {
var defaultOpt = {
box: "#fullPageBox", // 滚屏页父元素
page: ".fullPage", // 滚屏页面
index: true, // 是否显示索引
duration: 1000, // 动画时间
direction: "vertical", // 滚屏方向 horizontal or vertical
loop: true // 是否循环
},
This = this,
index = 0,
over = true;
this.option = $.extend({}, defaultOpt, option || {});
this.box = $(this.option.box);
this.pages = $(this.option.page);
this.duration = this.option.duration;
// 绑定鼠标滚轮事件
$(document).on("mousewheel DOMMouseScroll", function(ev) {
var dir = ev.originalEvent.wheelDelta || -ev.originalEvent.detail;
if (over === false) return;
dir < 0 ? nextPage() : prevPage();
});
if (this.option.index) {
initPagination();
};
function initPagination() {
var oUl = $("<ul id='fullPageIndex'></ul>"),
liStr = "";

How to create valid preloader with jQuery, which can preload mp3 file to browser cache?

I have a simple drawing spectrum on a website http://alldev.eu/html/mp3/index.phtml, which loads to browser cache a song and plays it after it's fully downloaded.
I've made a pre-loader for my site which displays a message and an image for 7 seconds while the song is being loaded. Unfortunately, it doesn't work in the way I'd like to since 7 seconds might not be enough time to load a song (for instance, a test song with 11 Megabytes)
How can I rebuild my site to pre-load all data? My current script is below:

you can give preloadJS a try.
http://www.createjs.com/#!/PreloadJS
here's some code from their documentation to get you started:
var queue = new createjs.LoadQueue();
queue.installPlugin(createjs.Sound);
queue.on("complete", handleComplete, this);
queue.loadFile({id:"sound", src:"http://path/to/sound.mp3"});
queue.loadManifest([
{id: "myImage", src:"path/to/myImage.jpg"}
]);
function handleComplete() {
createjs.Sound.play("sound");
var image = queue.getResult("myImage");
document.body.appendChild(image);
}
Check for JWPlayer API, you can have access to a method getBuffer(), which returns the current buffered state for your audio file : http://www.longtailvideo.com/support/jw-player/28851/javascript-api-reference/
But this requires to use JWplayer to play / handle your audio file, as it's not included in the audio object : http://www.w3schools.com/tags/av_prop_buffered.asp
EDIT :
I took some time to make it work, see the fiddle :) : http://jsfiddle.net/uKZ8N/
Basically, I set an interval of 0,5s which check the getBuffer() value.

Event Handlers On Newly Created Elements

I have a web app with a number of textareas and the ability to add more if you wish.
When you shift focus from one textarea to another, the one in focus animates to a larger size, and the rest shrink down.
When the page loads it handles the animation perfectly for the initial four boxes in the html file, but when you click on the button to add more textareas the animation fails to accomodate these new elements... that is, unless you place the initial queries in a function, and call that function from the addelement function tied to the button.
But!, when you do this it queries as many times as you add a new element. So, if you quickly add, say 10, new textareas, the next time you lay focus on any textarea the query runs 10 times.
Is the issue in my design, or jQueries implementation? If the former, how better can I design it, if it is the latter, how can I work around it?
I've tried to chop the code down to the relevant bits... I've tried everything from focus and blur, to keypresses, the latest is on click.

You should use the following:
// New way (jQuery 1.7+) - .on(events, selector, handler)
$(document).on("click", "textarea", function () {
event.preventDefault();
alert('testlink');
});
Since the textarea is added dynamically, you need to use event delegation to register the event handler.
Try
$(document).on('click', 'textarea', function() {
// do something
});
The issue is you are binding the textareas only on the page load. I made a JSFiddle with working code: http://jsfiddle.net/VpABC/
Here's what I changed:
I wrapped:
$('textarea').on("click", function () {
//alert(this.id.substring(0,3));
if (this.id.substring(0, 3) == 'box') {
$('textarea').animate({
height: "51"
}, 1000);
$(this).animate({
height: "409"
}, 1000);
} else {
$('textarea').animate({
height: "51"
}, 1000);
}
});
in a function so it looked like this:
function bindTextAreas() {
$('textarea').unbind("click");
$('textarea').on("click", function () {
//alert(this.id.substring(0,3));
if (this.id.substring(0, 3) == 'box') {
$('textarea').animate({
height: "51"
}, 1000);
$(this).animate({
height: "409"
}, 1000);
} else {
$('textarea').animate({
height: "51"
}, 1000);
}
});
}
bindTextAreas();
What this does is it allows you to call this function, bindTextAreas, whenever you create a new textarea. This will unbind all the current events than rebind them. This will make it so your new textarea is has the click handler setup.
An place where this function is called is in the addele function like this:
function addele() {
var tops = document.getElementById('top');
var num = numb + 1;
var romu = romanise(num);
var newbox = document.createElement('textarea');
var newboxid = 'box' + num;
newbox.setAttribute('id', newboxid);
newbox.setAttribute('class', 'tecksd');
newbox.setAttribute('placeholder', '(' + romu + ')');
tops.appendChild(newbox);
numb = num;
onit();
bindTextAreas();
} //addele(), add element
Notice the bindTextAreas(); line near the bottom. This reloads all the click handlers.
