jQuery - Hide / Show not displaying div and showing error - javascript

I was wondering if someone could help me out with a bit of jquery im trying to write.
Im quite new to jQuery so this is prob something easy.
I have a div with an id of 'about-box'
I want it to slide in and out of the viewport when a menu item is pressed.
I have the following jQuery.
<script type="text/javascript">
$(document).ready(function() {
$('#menu-item-1 a').click(function() {
if($('#about-box:visible').length)
$('#about-box').hide("slide", { direction: "left" }, 1000);
else
$('#about-box').show("slide", { direction: "left" }, 1000);
});
});
</script>
But i am getting the following error message:
Uncaught TypeError: undefined is not a function
Any help getting this to work would be greatly appreciated.

I think the problem is you are not including jQuery-UI in your page, the show/hide implementation you have used requires jQuery UI
$(document).ready(function() {
$('#menu-item-1 a').click(function() {
if ($('#about-box').stop(true, true).is(':visible')) {
$('#about-box').hide("slide", {
direction: "left"
}, 1000);
} else {
$('#about-box').show("slide", {
direction: "left"
}, 1000);
}
});
});
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.js"></script>
<link rel="stylesheet" type="text/css" href="http://ajax.googleapis.com/ajax/libs/jqueryui/1.10.4/themes/redmond/jquery-ui.css">
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.10.4/jquery-ui.js"></script>
<div id="menu-item-1"><a>menu-item-1 a</a></div>
<div id="about-box">about-box</div>
You can also use jQueryUI toggle
$(document).ready(function() {
$('#menu-item-1 a').click(function() {
$('#about-box').toggle("slide", {
direction: "left"
}, 1000);
});
});
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.js"></script>
<link rel="stylesheet" type="text/css" href="http://ajax.googleapis.com/ajax/libs/jqueryui/1.10.4/themes/redmond/jquery-ui.css">
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.10.4/jquery-ui.js"></script>
<div id="menu-item-1"><a>menu-item-1 a</a></div>
<div id="about-box">about-box</div>

since document is for sure a good element the undefined is not on the ready
:visible looks good see here http://api.jquery.com/visible-selector/
So the undefined must be here $('#menu-item-1 a').click or in other code in your page or on the execution of the ready.
Try to find where . remove the if else . does the undefined throw?? if yes the $('#menu-item-1 a') doesnt resolve.
wish it help

try changing the selector to
$('#about-box').is(':visible')

$('#about-box:visible') is a wrong selector,I think you can toggle a class on about-box button and decide slide in or out

jQuery(document).ready(function(){}); not working properly

In main.js
jQuery(document).ready(function(){
"use strict"
$(window).scroll(function(){
var top = $(window).scrollTop();
if(top>=60){
$("nav").addClass('secondary');
}
else{
if($("nav").hasClass('secondary')){
$("nav").removeClass('secondary');
}
}
});
});
In index.html
<head>
<link rel="stylesheet" href="css/style.css">
<script src="https://code.jquery.com/jquery-1.12.4.min.js" integrity="sha384-nvAa0+6Qg9clwYCGGPpDQLVpLNn0fRaROjHqs13t4Ggj3Ez50XnGQqc/r8MhnRDZ" crossorigin="anonymous"></script>
<script type="text/javascript" src="js/main.js"></script>
<head>
In style.css
.secondary{
background-color:#34495e;
}
It is a code for changing the class of a navigation bar with class 'nav' to the class 'secondary' when the page scroll to downwards
$(window).scroll(function(){
var top = $(window).scrollTop();
if(top>=60){
$("nav").addClass('secondary');
}
else{
if($("nav").hasClass('secondary')){
$("nav").removeClass('secondary');
}
}
});
The above code doesn't works fine inside
jQuery(document).ready(function(){});
but,
jQuery(document).ready(function(){
"use strict"
alert("hello world");
});
works fine and some other functions also works fine
but some functions not working.
can anyone help me to find the solution for this problem
Your code is correct. Check the value of top with console.log to make sure the scroll event is fired. Otherwise you will find an error about some other part of your code.
For example, this works and is also slightly optimised:
$(document).ready(function() {
"use strict";
var $win = $(window)
var $nav = $("nav");
$win.scroll(function() {
var top = $win.scrollTop();
console.log(top);
if (top >= 60) {
$nav.addClass("secondary");
} else if ($nav.hasClass("secondary")) {
$nav.removeClass("secondary");
}
});
});
Demo: https://codepen.io/taseenb/pen/QWbxRvP
You can check what the error is on browser's inspect tool.
If you press "F12", "Developer tools" panel will be shown.
And click "Console" on this panel and check which error has been occured.
And I guess you need to use "jQuery" keyword to select elements.
Or please try following code.
jQuery(document).ready(function($){
"use strict"
$(window).scroll(function(){
var top = $(window).scrollTop();
if(top>=60){
$("nav").addClass('secondary');
}
else{
if($("nav").hasClass('secondary')){
$("nav").removeClass('secondary');
}
}
});
});
If you can share your page url, I can help you to check error and find a solution.
you can try on this, it works to me
put source script
<script th:src="#{/richtext/jquery.richtext.min.js}"></script>
<script th:src="#{/richtext/jquery.richtext.js}"></script>
then script text:
<script type="text/javascript">
(function($) {
$('#shortDescription').richText();
$('#fullDescription').richText();
})(jQuery);
</script>

Javascript conflict in Html & CSS

I have a conflict with my JS as one of the scripts isn't functioning properly, I'm trying to use more than one javascript in my document, I will be using three and I'm getting a conflict already and I only have two in the document so far... :(
First in the head:
<script type="text/javascript" src="javascript/jquery_1.3.2.js"></script>
<script type="text/javascript" src="javascript/jcarousel.js"></script>
<script type="text/javascript">
jQuery(document).ready(function () {
jQuery('#jcarouselMetro').jcarousel({
scroll: 1,
wrap: 'both'
});
jQuery('#jcarouselInvites').jcarousel({
scroll: 1,
wrap: 'both'
});
});
</script>
Second in the body:
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js"></script>
<script src="javascript/jquery-css-transform.js" type="text/javascript"></script>
<script src="javascript/jquery-animate-css-rotate-scale.js" type="text/javascript"></script>
<script>
$('.item').hover(
function(){
var $this = $(this);
expand($this);
},
function(){
var $this = $(this);
collapse($this);
}
);
function expand($elem){
var angle = 0;
var t = setInterval(function () {
if(angle == 1440){
clearInterval(t);
return;
}
angle += 40;
$('.link',$elem).stop().animate({rotate: '+=-40deg'}, 0);
},10);
$elem.stop().animate({width:'243px'}, 1000)
.find('.item_content').fadeIn(400,function(){
$(this).find('p').stop(true,true).fadeIn(600);
});
}
function collapse($elem){
var angle = 1440;
var t = setInterval(function () {
if(angle == 0){
clearInterval(t);
return;
}
angle -= 40;
$('.link',$elem).stop().animate({rotate: '+=40deg'}, 0);
},10);
$elem.stop().animate({width:'52px'}, 1000)
.find('.item_content')
.stop(true,true)
.fadeOut()
.find('p')
.stop(true,true)
.fadeOut();
}
</script>
From what I can see it's the "function" that may be causing the issue. Please help... And how can you avoid these issues, I'm sure loads of people use multiple js all the time, do you just hope and pray it doesnt mess up?
Edited:
<script type="text/javascript" src="javascript/jquery-1.4.2.min.js"></script>
<script type="text/javascript" src="javascript/jquery.jcarousel.min.js"></script>
<script type="text/javascript" src="javascript/jquery.jcarousel.js"></script>
<script type="text/javascript">
jQuery(document).ready(function () {
jQuery('#jcarouselMetro').jcarousel({
scroll: 1,
wrap: 'both'
});
jQuery('#jcarouselInvites').jcarousel({
scroll: 1,
wrap: 'both'
});
});
</script>
Cleaning up your source code may help the debugging process..
Instead of using javascript contained within script tags within the body/head of your document, you can just create a separate javascript file. Place all of your external script tags within the head of the document. Your custom javascript file which contains all the above code should be called last.
Your click/hover functions should be contained/bound within your document.ready function.
Also, you are calling duplicate scripts, jcarousel.js and jcarousel.min.js are the same script. One is just the minified version. You are likely producing conflicts because of this, and the same would be true for your jquery calls. Try using just one version of jQuery, ie the latest version from scriptsrc.net
Your resulting html document would therefore look something like this
<head>
<!-- jquery -->
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js"></script>
<script type="text/javascript" src="javascript/jquery-css-transform.js"></script>
<script type="text/javascript" src="javascript/jquery-animate-css-rotate-scale.js"></script>
<script type="text/javascript" src="javascript/jquery.jcarousel.min.js"></script>
<!-- your custom js -->
<script type="text/javascript" src="javascript/yourCustom.js"></script>
</head>
your custom js file would then look like this..
function expand($elem) {
var angle = 0;
var t = setInterval(function() {
if (angle == 1440) {
clearInterval(t);
return;
}
angle += 40;
$('.link', $elem).stop().animate({
rotate : '+=-40deg'
}, 0);
}, 10);
$elem.stop().animate({
width : '243px'
}, 1000).find('.item_content').fadeIn(400, function() {
$(this).find('p').stop(true, true).fadeIn(600);
});
}//end expand
function collapse($elem) {
var angle = 1440;
var t = setInterval(function() {
if (angle == 0) {
clearInterval(t);
return;
}
angle -= 40;
$('.link', $elem).stop().animate({
rotate : '+=40deg'
}, 0);
}, 10);
$elem.stop().animate({
width : '52px'
}, 1000).find('.item_content').stop(true, true).fadeOut().find('p').stop(true, true).fadeOut();
}//end collapse
$(document).ready(function() {
//Carousel setup
$('#jcarouselMetro').jcarousel({
scroll : 1,
wrap : 'both'
});
$('#jcarouselInvites').jcarousel({
scroll : 1,
wrap : 'both'
});
//end carousel
//item hover function
$('.item').hover(function() {
var $this = $(this);
expand($this);
}, function() {
var $this = $(this);
collapse($this);
});
//end hover
});//end document ready
Further to all of this, you may need to define a clearInterval function. Unless it is part of one of the many libraries you have included, as it is called in your expand and collapse functions.
Hope this helps...
I can see two issues with conflicting JavaScript code being included twice. Firstly
you're loading two versions of the same carousel library here:
<script type="text/javascript" src="javascript/jquery.jcarousel.min.js"></script>
<script type="text/javascript" src="javascript/jquery.jcarousel.js"></script>
The first is a minified version of of the same code. You only need one, so remove the second line above as it won't be required and it's just a larger version of the same file. This may not be causing the issue, but it's not right.
Secondly you have two versions of jQuery in your code and that will also cause significant issues because you're loading them at very different times in your page and they will have very different functionality. You can fix this using noConflict:
<script type="text/javascript" src="javascript/jquery-1.4.2.min.js"></script>
<script type="text/javascript">
var jq142 = jQuery.noConflict();
jq142(document).ready(function () {
jQuery('#jcarouselMetro').jcarousel({
scroll: 1,
wrap: 'both'
});
jQuery('#jcarouselInvites').jcarousel({
scroll: 1,
wrap: 'both'
});
});
</script>
The first line var jq142 = jQuery.noConflict(); will ensure that you have the correct version of jQuery loaded for the carousel library. Read the noConflict documentation for more information.
You can use this to only load one version of the library. 1.3.2 on IE6,7,8 and 1.9.1 on all other browsers.
<!--[if lt IE 9]>
<script src="jquery-1.3.2.js"></script>
<![endif]-->
<!--[if gte IE 9]><!-->
<script src="jquery-1.9.1.js"></script>
<!--[endif]-->

jQuery UI dialog issue

I'm trying to create jquery dialog, but there is no use :(
here is my jQuery code:
$(document).ready(function() {
createDialog();
});
function createDialog() {
$("#dialog:ui-dialog").dialog("destroy");
$("#dialog-form").dialog(
{
autoOpen : false,
height : 475,
width : 350,
modal : true,
buttons : {
"submit" : function() {
var bValid = true;
allFields.removeClass("ui-state-error");
postText();
$(this).dialog("close");
}
},
cancel : function() {
$(this).dialog("close");
}
},
close : function() {
allFields.val("").removeClass("ui-state-error");
}
});
$(".add-org").click(function() {
$("#dialog-form").dialog("open");
});
}
here is html code:
<link href="<c:url value="/resources/styles/jquery-ui-1.8.21.custom.css"/>"
rel="stylesheet" type="text/css">
<script type="text/javascript"
src="<c:url value='/resources/js/jquery-1.7.js'/>"></script>
<script type="text/javascript"
src="<c:url value='/resources/js/jquery-ui-1.8.21.custom.min.js'/>"></script>
<script type="text/javascript"
src="<c:url value='/resources/js/myScript.js'/>"></script>
New
<div id="dialog-form" title="Add New ">
<p class="validateTips">All form fields are required.</p>
<form>
..................
</form>
</div>
and firebug says:
TypeError: $("#dialog:ui-dialog").dialog is not a function
$("#dialog:ui-dialog").dialog("destroy");
and on my page I see all the fields from the form.
so what is my problem?
Try this: Working demo http://jsfiddle.net/kEZkh/
Not sure if your source path are correct please include following scripts.
rest please feel free to play around with demo & hope it helps the cause :)
scripts
<link rel="stylesheet" type="text/css" href="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8.11/themes/base/jquery-ui.css">
<link rel="stylesheet" type="text/css" href="http://static.jquery.com/ui/css/demo-docs-theme/ui.theme.css">
<script type='text/javascript' src='https://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js'></script>
<script type="text/javascript" src="http://code.jquery.com/ui/1.8.18/jquery-ui.min.js"></script>
code
$("#forgot").click(function(e){
$("#dialog-form").dialog("open");
e.preventDefault();
});
$("#dialog-form").dialog({
modal: true,
autoOpen: false,
height: 255,
width: 300,
buttons: {
"Retrieve": function() {
document.forms["forgotform"].submit();
},
Cancel: function() {
$( this ).dialog( "close" );
}
},
});
​
Check in Firebug/DevTools if the script file was loaded successfully. If it is, type this into the console (Firebug, DevTools) or better, put that line where your other code is executed:
console.debug(jQuery.ui)
If it shows undefined, then jQuery UI was not loaded (yet). Check if your code runs before everything was loaded, put it inside jQuery's $(document).ready();. If it is an object, inspect it and check for the dialog property.
If you configured a custom build on jqueryui.com, doublecheck if you included the dialog widget.
The destroy call should be on the same element as you already used when you created the dialog, not the .ui-dialog container that gets wrapped around your content:
$("#dialog-form").dialog('destroy');
Since your current code is throwing an exception, the subsequent lines which are supposed to create the dialog never get called.
If you want to destroy every dialog that might already be open, jQuery UI handily puts a .ui-dialog-content class on each content div:
$('.ui-dialog-content').dialog('destroy');

why my jquery codes doesn't run?

I want to toggle element that id's pg when click link.
header:
<title>Example</title>
<script type="text/javascript" src="jquery-1.3.2.js"></script>
<script type="text/javascript">
$(function() {
$("#link").click(function() {
$("#pg").toggle();
});
</script>
Elements:
<p id="pg">deneme deneme 123 deneme</p>
toggle
close click function by adding });:
$(function() {
$("#link").click(function() {
$("#pg").toggle();
});
});
You're missing the final }); for the statement
<title>Example</title>
<script type="text/javascript" src="jquery-1.3.2.js"></script>
<script type="text/javascript">
$(function() {
$("#link").click(function() {
$("#pg").toggle();
});
)}; //<-- Missing close bracket
</script>
Also, if you're using Firefox, check out Firebug. Its an invaluable debugger tool and will show you where errors are happening.
Chrome has a Developer Tools enabled, not sure about IE.

One way of prepending html with jquery works but why the other way doesn't?

This way of prepending does work for me:
<script type="text/javascript" charset="utf-8">
$(document).ready(function() {
$("#learn-more-button").click(function() {
$("#main-text").load('ajax/learn-more.html #learn-more', function() {
$(this).prepend('<p> DARN </p>'); // <=== This here WORKS
$(this).hide().fadeIn(500); //Fade in
$("#main-text").animate({ // Then Animate
width:"500px",
left:'+=400px',},
400
);
});
});
});
</script>
This way of prepending doesn't work for me:
<script type="text/javascript" charset="utf-8">
$(document).ready(function() {
$("#learn-more-button").click(function() {
$("#main-text").prepend('<p> DARN </p>'); // <=== This here doesn't work
$("#main-text").load('ajax/learn-more.html #learn-more', function() {
$(this).hide().fadeIn(500); //Fade in
$("#main-text").animate({ // Then Animate
width:"500px",
left:'+=400px',},
400
);
});
});
});
</script>
Why the second way doesn't work? How should it be done to make it work?
I'm not really a jQuery guy, so help is appreciated :)
When you perform the load() the contents of the #main-text element are completely replaced. Therefore if you add the <p>DARN</p> before the load - as in the second method, it gets overwritten.
In the first method the <p> is being added in the callback function of the load. This is called after the load has been completed.
You should also chain methods on to one selector for better performance, like this:
<script type="text/javascript" charset="utf-8">
$(document).ready(function() {
$("#learn-more-button").click(function() {
$("#main-text").load('ajax/learn-more.html #learn-more', function() {
$(this).prepend('<p> DARN </p>')
.hide().fadeIn(500)
.animate({
width:"500px",
left:'+=400px'
}, 400);
});
});
});
</script>
