As i have dynamic added content i need to use "document" as the selector for my event.
$(document).hover(function(){
//Do something
}
Now i'd like to know if i can also use a class as a selector?
I tried:
$(document).hover('.liDoc', function(){
$(this).children('.delDoc').css('color', 'red'); console.log($(this).children('.delDoc'))
}, function() {
// on mouseout, reset the background colour
$(this).children('.delDoc').css('color', '');
});
This one don't work! It seems like whole document is target.
When using .on() i can do it like this...but .on('hover')is deprecated?!
You need to delegate mouseenter/mouseleave events and filter by type event, e.g:
$(document).on('mouseenter mouseleave', '.liDoc', function(e) {
$(this).children('.delDoc').css('color', e.type === "mouseenter" ? 'red' : '');
});
But you would have better to toggle a class instead:
$(document).on('mouseenter mouseleave', '.liDoc', function(e) {
$(this).children('.delDoc').toggleClass('colored');
});
with in CSS:
.delDoc.colored {
color: red;
}
OR just use CSS if your use-case is simple as the one you posted:
.liDoc:hover > .delDoc {
color: red;
}
please try below code
<!DOCTYPE html>
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js"></script>
<script>
$(document).ready(function(){
$("p").hover(function(){
$(this).css("background-color", "yellow");
}, function(){
$(this).css("background-color", "pink");
});
});
</script>
</head>
<body>
<p>Hover the mouse pointer over this paragraph.</p>
</body>
</html>
You can use the class name as the selector directly.
Of course, you need to import the jQuery library first for this to work.
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min"></script>
If you already downloaded the jQuery library (recommended) then the "src" value should lead to the file. If not, you can reference it directly with the URL above.
And now, your jQuery codes
<script>
$(document).ready(function(){
$(".liDoc").hover(function(){
//mouse is in.. Do something
$(this).children(".delDoc").css("background","red");
}, function(){
//mouse is out.. Do something
$(this).children(".delDoc").css("background","transparent");
});
});
</script>

I want to change the CSS for the element btn1 (its a button) while its active.
I want to look different as long as "story" is shown (when pressed shows a div, as long as the div is shown i want the button to have a different color from the normal css)
$(function() {
$('#btn1').on('click', function() {
$('#story').fadeToggle(400);
});
});
$('#btn1').on('click', function() {
$(this).toggleClass('active'); // add/remove a css class
$('#story').fadeToggle(400);
});
in your css add
.active{
// styles you wish to apply
}
Try .css() method:
$('#btn1').on('click', function() {
$(this).css({'border':'1px solid blue', 'color':'red'});
$('#story').fadeToggle(400);
});
Working Example
:active selector https://developer.mozilla.org/en-US/docs/Web/CSS/:active
and look on this site http://www.paulund.co.uk/css3-buttons-with-pseudo-classes
It sounds like you want to do this:
$(function() {
$('#btn1').on('click', function() {
$(this).css('background-color','red'); // or whatever
$('#story').fadeToggle(400, function() { // 'complete' callback function
$('#btn1').css('background-color','white');
});
});
});
index.html:
<html>
<head>
<title>chapter 5</title>
<script src="jquery.js"></script>
<script src="app.js"></script>
</head>
<body>
<div >
<p>this is a paragraph</p>
</div>
</body>
</html>
app.js:
$(function() {
$("div").on("hover", function(event) {
if(event.type === "mouseenter") {
$(this).css("background", "blue");
}
else {
$(this).css("background", "red");
}
});
});
so according to my Jquery: when I bring mouse over to tags it should change its colour to red and when any other even inside tag except mouse enter it should change to blue. But nothing is happening?
I have tried other functions with event which works fairly well I can not understand why this one is not working do I have to do something with "css" maybe?
From the jQuery's .on() method documentation:
Deprecated in jQuery 1.8, removed in 1.9: The name "hover" used as a shorthand for the string "mouseenter mouseleave". It attaches a single event handler for those two events, and the handler must examine event.type to determine whether the event is mouseenter or mouseleave. Do not confuse the "hover" pseudo-event-name with the .hover() method, which accepts one or two functions.
Listen to mouseenter and mouseleave events instead of the hover:
$("div").on("mouseenter mouseleave", function(event) {
$(this).css("background", event.type === "mouseenter" ? "blue" : "red");
});
Alternatively you can pass an object to the .on() method:
$("div").on({
mouseenter: function() {
$(this).css("background", "blue");
},
mouseleave: function() {
$(this).css("background", "red");
}
});
I have replicated my issue in jsfiddle: http://jsfiddle.net/66UCX/
All I want to do is toggle between red and white when the user clicks on the td in a table. I have tried using an if statement to test for the background colour like so :
if($("#fbodytd_"+uid+"_"+row+"_"+col).css("background-color") == "rgb(255, 0, 0)"){
and that didn't work so I have tried adding and removing a class called 'active' and testing for that. Thanks.
You didn't make any binding on your function function changecream(uid, row, col).
Here is a working Fiddle:
$("table").on("click", "td", function(){
if($(this).hasClass("red")){
$(this).removeClass("red").addClass("white");
} else {
$(this).removeClass("white").addClass("red");
}
});
Edit:
Of yourse if you are only toggling between background color and a chosen color, you could simplify the "on click":
$(this).toggleClass("red");
You have to include jquery library
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.8/jquery.min.js" type="text/javascript"></script>
and your code look like this in $(document).ready function
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.8/jquery.min.js" type="text/javascript"></script>
<script>
$(document).ready(function(){
$('#button').bind('click', function(){
$(this).after('<span> click is active</span>');
$('span').fadeOut(1000);
});
$('#toggle').toggle(
function(){
$(this).text('rebind').removeClass('unbind').addClass('rebind');
},
function(){
$(this).text('unbind').addClass('unbind').removeClass('rebind');
}
);
if($("#toggle").hasClass("unbind")) {
$('#button').bind('click');
}
else {
$('#button').unbind('click');
}
});
</script>
If all you want is to simply change the background back and fourth (and maybe something else also). Add class like
.active
{
background-color: Red
}
and use a code like so:
$("table").on("click", "td", function() {
$(this).toggleClass("active");
});
Hope this helps.
If you are using jQuery anyway, the following simplified version should do:
$('table.bodymap td').click(function () {
$(this).toggleClass('active')
});
See this fiddle for a working example.
Status: WORKING
Runs smoothly - click works
Jquery
$("document").ready(function(){
$("#test").click(function(){
alert("abc");
});
});
CSS
.blue {
background-color:blue;
}
Tag Body
<body>
<div class="blue" id="test">Testing code</div>
</body>
Status: NOT WORKING
Succeeds to add the file and div test within it but click doesn't work
Jquery
$("document").ready(function(){
$.get("new.php", {
// this math avoids IE from crashing
nbRandom: Math.random()
},
function(data){
$("body").html(data);
});
$("#test").click(function(){
alert("abc");
});
});
CSS
.blue {
background-color:blue;
}
Tag Body
<body>
</body>
Does anybody know how to do that?
The method get is asynchronous which means that the stream will continue while the ajax request is still running, the best solution is to put the click handler into the get callback.
$("document").ready(function(){
$.get("new.php", {
// this math avoids IE from crashing
nbRandom: Math.random()
},
function(data){
$("body").html(data);
$("#test").click(function(){
alert("abc");
});
});
});
You should delegate the event, from one of static parents of the element or document object.
$(document).on("click", "#test", function(){
alert("abc");
})
use delegate or on(recommend)
$(function() {
$('body').on('click', '#test', function() { alert('abc'); });
// or
// $('body').delegate('#test', function() { alert('abc'); });
});
problem is the the click function is called before the div with #test is appended...
call click function after the div is appended.. so that it gets that id... and the event
try this
$.get("new.php", {
// this math avoids IE from crashing
nbRandom: Math.random()
},
function(data){
$("body").html(data);
$("#test").click(function(){
alert("abc");
});
});
OR
the on function with selector as document..(i alway prefer to go with this)
$(document).on("click", "#test", function(){
alert("abc");
})
Im trying to toggle some divs and its not working, here is the js:
<script type="text/javascript">
$(function(){
$('#toggle_full').click(function(){
$('#full_size').removeClass('toggle');
$('#thumb_list').addClass('toggle');
});
});
$(function(){
$('#toggle_thumb').click(function(){
$('#thumb_list').removeClass('toggle');
$('#full_size').addClass('toggle');
});
});
</script>
Here are the anchors:
<div class="toggle_block">
<img src="img/full_icon.jpg" alt="#"/>
<img src="img/thumbs_icon.jpg" alt="#"/>
</div>
Here is the class:
.toggle {
display: none;
}
Now where is the problem?
Your ID's don't match.
In your HTML you have toggle_thumbs, but in your code you have toggle_thumb.
If all you're doing is hiding and showing, you can greatly simplify your code like this:
http://jsfiddle.net/xTPU8/2/
$(function() {
var $elems = $('#toggle_full').hide()
.add('#toggle_thumb').click(function() {
$elems.toggle();
});
});
EDIT: Made it even a little more efficient.
Add a return false; in your .click() delegate to prevent the browser from navigating to '#' (jumps to top of page).
You can also simplify your JS but putting both of your link bindings in the same, and using hide() and show() as already suggested. The end result would be:
<script type="text/javascript">
$(function() {
$('#toggle_full').click(function() {
$('#full_size').show();
$('#thumb_list').hide();
return false;
});
$('#toggle_thumb').click(function() {
$('#thumb_list').show();
$('#full_size').hide();
return false;
});
});
</script>
