I have a sprite image than when mouseenter/mouseleave occurs over it, the background position changes.This is working so far although there is probably a more efficient way of doing it. However I have several images I need to do this with and am trying to find a way to feed the id of the image into the jQuery rather than duplicate code.
The HTML:
<div class='featSmallBox' id='featSmallImg2'>
</div>
The image source is placed using CSS.
This is what I have so far for the jQuery.
$("#featSmallImg2").mouseenter(function(){
$(this).animate({
backgroundPositionX:"100%"
});
});
$("#featSmallImg2").mouseleave(function(){
$(this).animate({
backgroundPositionX:"0%"
});
});
Ideally I need to feed in the id of what is being mouseentered dynamically, but everything I've tried doesn't seem to work.
Apologies if this makes little to no sense. I'm new to both jQuery and this site.
If the jQuery code is the same for all divs containing the sprites, try changing $("#featSmallImg2") in your jQuery to $(".featSmallBox"). This way, all your divs with the class .featSmallBox will have this feature.
Check with event.target
$( "body" ).mouseenter(function( event ) {
console.log( "mouseentered id: " + event.target.id);
});
$("div[id^='featSmallImg']").mouseenter(function(){
$(this).animate({
backgroundPositionX:"100%"
});
});
$("div[id^='featSmallImg']").mouseleave(function(){
$(this).animate({
backgroundPositionX:"0%"
});
});
Try this code. Event will be called for all div's whose id starts with 'featSmallImg'

I aim is to have the medium blue box and everything in it move up when the search button is pressed.
I know my selector is for "form" and it's trying to change the background, I'm having trouble getting anything to animate.
I think this is the correct way to accomplish it but nothing happens:
$("#search-btn").click(function{
$("controls-main").animate({
background: "red"
}, 500);
})
In the fiddle:
Second click handler was missing parentheses (syntax error in console)
s-form class was missing from your form html code (empty selector)
$('search') is a wrong selector. You probably wanted $('[name=search]');
You are animating background, which jQuery's animate doesn't animate.
Updated working fiddle: https://jsfiddle.net/9hcoy9j8/18/
$(document).ready(function() {
$(".rand-wiki").click(function() {
window.open("https://en.wikipedia.org/wiki/Special:Random");
});
$(".s-form").on('click', function () {
$("[name=search]").animate({
marginTop: '40px'
}, 500);
});
});
jQuery on its own can't animate colors. You need another library like jQuery UI. See this SO answer for more information.
I am using Jquery to make click events. It is simple when I am changing css properties, but one of my elements I am trying to change (a canvas) the size in HTML.
I am trying to access and change this html code on a click - width and height:
<canvas id="testCanvas" width="755" height="500" > </canvas>
with this jquery
$('#flipthehood').click(function(){
console.log('hood flipped clicked');
$getElementById('testCanvas').animate({width="200"}, 250);
})
Is this the best way to go about it? if so, could I please have some advice with the syntax to make it work? I am getting an error of unexpected = sign
Thanks a lot
Fetch element using id selector in jquery,
document.getElementById('testCanvas') is equivalent to $('#testCanvas')
and the correct syntax for .animate() is like:
$('#testCanvas').animate({width:"200"}, 250);
Make sure your click events are when the document is ready. Also document.getElementById isn't used in JQuery. This works:
$(document).ready(function() {
$('#flipthehood').click(function(){
console.log('hood flipped clicked');
$('#testCanvas').attr("width", "200");
});
});
If you want it to be a smooth animation simply change it to this:
$(document).ready(function() {
$('#flipthehood').click(function(){
console.log('hood flipped clicked');
$('#testCanvas').animate({width: "200"}, 250);
});
});
$.animate uses a colon instead of an equals sign.
To change an element attribute with jQuery use the .attr() method:
$("#testCanvas).attr("width", 200)
This is a question that is related to a previous question of another member which can be found here.
This is the Javascript function to hide a div (which is an answer to the other member's question):
function hide(obj) {
var el = document.getElementById(obj);
el.style.display = 'none';
}
The HTML is:
<div id='hideme'>
Warning: These are new products
<a href='#' class='close_notification' title='Click to Close'>
<img src="images/close_icon.gif" width="6" height="6" alt="Close" onClick="hide('hideme')" />
</a>
</div>
My followup question to this is: how can I add a cool effect of transition? The result will be the div 'hideme' would close slowly. Is there a work around for this?
Thanks so much everyone! It would be highly appreciated!
Note: I'm a noob with Javascript. 0-0
$("#"+el).fadeOut(500);//el must be the id of the element
If you're using jQuery
function hide() {
$(this).parent().fadeOut();
}
As this is triggered by an event the 'this' variable will be set to the element from which it came, as you want the parent element to vanish when it's clicked this will do the trick
EDIT: For this to work you may have to play with your HTML and how many $(this).parent().parent()... you need but this would be the best way to go about it, then you don't need to pass the ID around
EDIT 2: So .parent() selects the element containing the selected element, so in this case $(this) refers to the button that was clicked as that's where the click event came from.
So $(this).parent() refers to the container element, in this case the a element and therefore the $(this).parent().parent() refers to the div element which you want to hide.
So you could give the image a class of 'closable' then do the following
$('.closable').click(function() {
$(this).parent().parent().fadeOut();
}
This means whenever you click something with the class closable it will go up the DOM tree two elements to (with .parent().parent()) and then fade it out.
This will allow you to remove the on click event from the image, you just need to put the handler above in the jQuery document.ready function which looks like:
$(document).ready(function() {
//Click function here
});
A popular choice for this would be JQuery UI's effect method.
With this, you can write some very simple Javascript to hide your div in a stylish manner, for example:
function hide(obj) {
$(obj).effect("scale");
}
EDIT:
Here's an example jsFiddle
Use jQuery to do transition effects:
$(function(){
$("a.close_notification").click(function(e){
e.preventDefault();
// stop other animations and hide, 500 milliseconds
// you can use the function fadeOut for that too
$("#hideme").stop().hide(500);
});
});
I am currently working on a website and got stuck with the following problem:
On the website I have small dots (images) with the ids "dot0001", "dot0002", "dot0003", etc. . I also have hidden images (visibility:hidden) with the ids "info0001", "info00002", "info0003", etc.
I am looking for a jQuery solution. What I need is a code that allows the following events:
When users move the mouse over "dot0001" the image "info0001" becomes visible and when they leave "dot0001", "info0001" becomes invisible again. Same applies to "dot0002"-"info0002" , "dot0003"-"info0003" etc. So only the info-images with the corresponding 4 digit number become visible.
I gave it endless tries but got nowhere and there is not even a point in pasting my code.
Any help appreciated!
Something like this should work (though untested):
$('[id^="dot"]').on({
mouseenter: function(e) {
var infoId = this.id.replace('dot', 'info');
$('#' + infoId).show();
},
mouseleave: function(e) {
var infoId = this.id.replace('dot', 'info');
$('#' + infoId).hide();
}
});
That uses an attribute-starts-with selector to select all elements with an id beginning with "dot", then binds the event handlers to them. The event handler functions themselves simply replace the "dot" part of the id with "info" to form the correct new one, then show or hide the element as appropriate.
Don't forget to wrap that code in a DOM ready event handler so that it executes once the elements actually exist, otherwise it won't work.
Get all elements which id starts with "dot" and show/hide related "info" on mouseover/out:
$("[id^=dot]").hover(
function(){
$("#info" + this.id.substring(3)).css({"visibility":"visible"});
},
function(){
$("#info" + this.id.substring(3)).css({"visibility":"hidden"});
}
);

I have a div like this:
<div>
<font class='slideclick'>Click here to slidedown dynamic content</font>
<div class='slidedownonclick'> This is the content that slides down </div>
</div>
Jquery triggers the 'slidedownonclick' to slidedown when 'slideclick' is clicked. This works great but i have and indefinite amount on these div's reccuring in the same webpage, from a mysql database. Giving them unique id's is impossible. Is there any way that i could get only the 'slidedownonclick' in the same div as its respective 'slideclick' to slidedown when it is clicked.
Any help would be much appreciated,
thanks,
This will slide down the next .slidedownonclick div when .slideclick is clicked:
$('.slideclick').click(function() {
$(this).next('.slidedownonclick').slideDown();
});
On a .slideclick handler you will find that sibling with:
$(this).find('+ .slidedownonclick');
or:
$(this).next('.slidedownonclick');
$('.slideclick').click(function() {
$(this).next('.slidedownonclick').animate({
height: '+=50'
}, 1000);
});
Check about jQuery.next(), it's what do you want.
Using it you can get the next sibbling which class/id is the selector.
EDITED:
until jQuery 1.6.4
jQuery(document).delegate('font.slideclick', 'click', function() {
jQuery(this).next('slidedownonclick').slideToggle();
});
jQuery 1.7 +
jQuery(document).on('click', 'font.slideclick', function() {
jQuery(this).next('slidedownonclick').slideToggle();
});
