Consider the following code:
<div id="thediv" >hola</div>
<button id="resharper">button</button>
with javascript/jQuery:
$("button").on( 'click', function() {
$("#thediv").show();
alert('click');
});
$(document).ready(function(){
$("#thediv").hide();
})
I want the behavior to first show the div tag and then display the alert "Click". Instead the behavior works in the opposite way. Alert text is first displayed followed by the button being visible. Am i missing something ?
Can i modify the code somehow to get the desired behavior where the div is first displayed and then alert text is flashed.
Check that in jQuery.show(options) allows you to pass a PlainObject options.
And than you can use complete: A function that is called once the animation on an element is complete.
Code:
$("button").on( 'click', function() {
$("#thediv").show({
complete: function() {
alert('click');
}
});
});
$(document).ready(function(){
$("#thediv").hide();
})
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="thediv" >hola</div>
<button id="resharper">button</button>
with javascript/jQuery:
It's because the alert() blocks the UI thread from updating, and that thread has not yet had time to show the element in the DOM before you call the alert().
Ideally you should use console.log() for debugging, however you can avoid this issue by putting the alert() in a setTimeout() with a very short delay.
$("button").on( 'click', function() {
$("#thediv").show();
setTimeout(function() {
alert('click');
}, 10);
});
#thediv { display: none; }
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="thediv" >hola</div>
<button id="resharper">button</button>
with javascript/jQuery:
$("button").on('click', function() {
$("#thediv").show("slow", callback);
});
$(document).ready(function() {
$("#thediv").hide();
})
function callback() {
alert('click');
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="thediv">hola</div>
<button id="resharper">button</button>

I need to hide a div by clicking on it and AFTER the div is hidden - an alert should appears.
Problem - the alert appears BEFORE the div is hidden.
$('.lorem').on('click', function(){
$(this).hide();
alert('LOREM IS HIDDEN');
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class='lorem'>LOREM</div>
JQuery's .hide offers a callback for when the element has disappeared.
$('.lorem').on('click', function(){
$(this).hide(function() {
alert('LOREM IS HIDDEN');
});
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class='lorem'>LOREM</div>
1.Using setTimeout will give you result you want
$('.lorem').on('click', function(){
$(this).hide();
setTimeout(function(){alert('LOREM IS HIDDEN')} , 0);
})
2.You can also use callback as second parameter of hide function
https://api.jquery.com/hide/
$('.lorem').on('click', function(){
$(this).hide(function() {
alert('LOREM IS HIDDEN'););
})
I would like to use blinking text to signify that data is loading. Then
hide it once the data is loaded.
I'm also using Flask.
I'm a JQuery newbie and found a recipe for flashing text, but it has the side effect, that hide didn't work.
SO answer
setInterval(function() {
$( "#blink" ).fadeToggle();
}, 500);
The I tried to hide after loading data into a div.
$("#data").load("/load_data/", function() {
$("#blink").hide('fast')
});
HTML:
<p id="blink">Loading Data</p>
<div id="data"></div>
Does this not work or am I just screwing it up...?
Is there another simple solution ?
TIA !!
Happy NY's
UPDATE:
Debugging Andrew Brooke's answer customized for a callback on load.
$("#data").load("/load_data/", function() {
$.clearInterval(blink);
$("#blink).hide("fast")
});
Assign your interval to a variable, then clear it in the .load callback with clearInterval. Then you can hide the blinking text with .hide
var blink = setInterval(function() {
$('#blink').fadeToggle();
}, 500);
$('#data').load('/load_data/', function() {
clearInterval(blink);
$('#blink').hide('fast');
});
Here's a working example
var blink = setInterval(function() {
$('#blink').fadeToggle();
}, 500);
$('#hide').on('click', function() {
clearInterval(blink);
$('#blink').hide('fast');
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input type="button" value="Hide" id="hide">
<p id="blink">
This is blinking
</p>
You forgot some quotation marks.
("#data").load("/load_data/", function() {
$("#blink").hide('fast')
});

I am attempting to delay the swapping of text in a div. It should operate like a slider/carousel for text.
I must have the code wrong, as the final text replacement never happens.
Also, how would I animate introducing the replacement text (window blinds, for eg.)?
<html>
<head>
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
<script src="//ajax.googleapis.com/ajax/libs/jqueryui/1.10.3/jquery-ui.min.js"></script>
<link rel="stylesheet" href="http://code.jquery.com/ui/1.9.1/themes/base/jquery-ui.css" />
<script type="text/javascript">
$(document).ready(function() {
$("#showDiv").click(function() {
$('#theDiv').show(1000, function() {
setTimeout(function() {
$('#theDiv').html('Here is some replacement text', function() {
setTimeout(function() {
$('#theDiv').html('More replacement text goes here');
}, 2500);
});
}, 2500);
});
}); //click function ends
}); //END $(document).ready()
</script>
</head>
<body>
Below me is a DIV called "theDiv".<br><br>
<div id="theDiv" style="background-color:yellow;display:none;width:30%;margin:0 auto;">
This text is inside the Div called "theDiv".
</div><br>
<br>
<input type="button" id="showDiv" value="Show DIV">
</body>
</html>
.html() only takes a string OR a function as an argument, not both. Try this:
$("#showDiv").click(function () {
$('#theDiv').show(1000, function () {
setTimeout(function () {
$('#theDiv').html(function () {
setTimeout(function () {
$('#theDiv').html('Here is some replacement text');
}, 0);
setTimeout(function () {
$('#theDiv').html('More replacement text goes here');
}, 2500);
});
}, 2500);
});
}); //click function ends
jsFiddle example
Try this:
function explode(){
alert("Boom!");
}
setTimeout(explode, 2000);
You can also use jQuery's delay() method instead of setTimeout(). It'll give you much more readable code. Here's an example from the docs:
$( "#foo" ).slideUp( 300 ).delay( 800 ).fadeIn( 400 );
The only limitation (that I'm aware of) is that it doesn't give you a way to clear the timeout. If you need to do that then you're better off sticking with all the nested callbacks that setTimeout thrusts upon you.
This is how I solved the problem
The menu closes a few seconds after mouse out (that if hover didn't fire),
//Set timer switch
$setM_swith=0;
$(function(){
$(".navbar-nav li a").click(function(event) {
if (!$(this).parent().hasClass('dropdown'))
$(".navbar-collapse").collapse('hide');
});
$(".navbar-collapse").mouseleave(function(){
$setM_swith=1;
setTimeout(function(){
if($setM_swith==1) {
$(".navbar-collapse").collapse('hide');
$setM_swith=0;}
}, 3000);
});
$(".navbar-collapse").mouseover(function() {
$setM_swith=0;
});
});

});
CSS
.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");
})
<script>
$("#menu-item-58").mouseover(function() { $("#simple_sidenav-3").css('visibility','visible'); });
$("#menu-item-58").mouseout(function() { $("#simple_sidenav-3").css('visibility','hidden'); });
</script>
#simple_sidenav-3 {
visibility:hidden;
}
simple_sidenav-3 is a hidden div.
So why doesn't it show when mouse is over #menu-item-58?
Please check it here http://mentor.com.tr/wp/?page_id=164
try this instead:
jQuery("#menu-item-58").mouseover(function() {
jQuery("#simple_sidenav-3").css('visibility','visible');
});
$ is undefined.
You haven't wrapped your code in the jQuery DOM ready function. Put this between your <script> tags:
$(document).ready(function()
{
$("#menu-item-58").mouseover(function() { $("#simple_sidenav-3").css('visibility','visible'); });
$("#menu-item-58").mouseout(function() { $("#simple_sidenav-3").css('visibility','hidden'); });
}
This will bind the mouse events to the elements when the document (page) has been loaded.
Try changing #simple_sidenav-3 from visibility:hidden; to display:none; Then call something like .slideDown() for a nice effect.
Also, here's some improvements to your code:
jQuery(function() { //waits till the document is ready
jQuery("#menu-item-58").mouseover(function () {
jQuery("#simple_sidenav-3").slideDown();
}).mouseout(function () { //no need to use $("#menu-item-58") twice
jQuery("#simple_sidenav-3").slideUp();
});
});
