Is this possible? I've got one jquery file that is loaded in every page that uses the .load() event, but then a few select pages also require some specific jquery stuff where I'd like to use .load() again. Thanks for reading.
Yep, that's no worries.
The events will run in the order they were defined:
$(function() {
$('body').append('<span>A</span>');
});
$(function() {
$('body').append('<span>B</span>');
});
$(function() {
$('body').append('<span>C</span>');
});
The above would append "ABC" to the page.
Interestingly, if you use the long-hand method, it completes in a different order:
$(function() {
$('body').append('<span>A</span>');
});
$(document).ready(function() {
$('body').append('<span>B</span>');
});
$(function() {
$('body').append('<span>C</span>');
});
This outputs "ACB"
Even more confusingly, if you only use the longhand, then it appears as though the first handler runs last and the rest in order:
$(document).ready(function() { /* A */ });
$(document).ready(function() { /* B */ });
$(document).ready(function() { /* C */ });
$(document).ready(function() { /* D */ });
$(document).ready(function() { /* E */ });

I'm working on a website with two banners- one for mobile and one for desktop. In order to have both banners functioning I had to write an if statement that a past of the dsktop javascript is only executed if the desktop banneris set to display:block in the css.
This works fine, but the only problem is when the user resizes the window the if statement doesn't get executed- they have to reload the page to do that.
this is the code :
var wait = setInterval(function () {
if (!$(currentBanner, loading).is(":animated")) {
clearInterval(wait);
loading.stop().fadeOut(300, function () {
if ($('#banner').css('display') == 'block'){
setTimeout(function() {
bannerInit();
}, 800);
startInterval();
if (initialLoad) {
initialLoad = false;
next.slideDown();
previous.slideDown();
}
}
});
}
Does anybody know how I can trigger the if statement not only on page load but also on resizing of the window?
Like this:
// on document ready
$( document ).ready(function() {
/* your function/code here */
});
// on page load, all elements finished e.g images etc
$(window).load(function() {
/* your function/code here */
});
// on page resize
$(window).on('resize', function(){
/* your function/code here */
};
Or vanilla JS:
// page load
window.onload = function() {
/* your function/code here */
};
// resize
window.addEventListener("resize", myFunctionOnResize);
I inherited this modal/overlay/content close/empty method that works, but abruptly:
method.close = function () {
$modal.hide();
$overlay.hide();
$content.empty();
$(window).unbind('resize.modal');
};
To fade out gradually, I modified the method like below, but elements are left behind and subsequent clicks don't open new modals loaded with content, only the overlay:
method.close = function () {
$modal.fadeOut('slow', function() {
$(this).hide();
});
$overlay.fadeOut('slow', function() {
$(this).hide();
});
$content.fadeOut('slow', function() {
$(this).empty();
});
$(window).unbind('resize.modal');
};
What am I missing?
UPDATE: The solution is a single nested callback, based on garryp's answer, like this:
method.close = function() {
$overlay.fadeOut('slow', function() {
$overlay.hide();
$content.empty();
});
$modal.hide();
$(window).unbind('resize.modal');
};
Hide is asynchronous; the calls you have in your original code do not block while the transition occurs, execution moves immediately to the next. You need to use callbacks, like this:
var me = $(this); //Added to ensure correct this context
$modal.fadeOut('slow', function () {
me.hide(function () {
$overlay.fadeOut('slow', function () {
me.hide(function () {
$content.fadeOut('slow', function () {
me.empty();
});
});
});
});
});
Assuming the rest of your code is correct this should ensure the transitions fire one after the next.
Firstly, you do not need $(this).hide(). JQuery fadeOut automatically set display: none at the end of fading animation (read more: http://api.jquery.com/fadeout/).
That mean, in your case $content element will also have display: none after fadeOut animation. I expect you forgot to add $content.show() in modal open method.
I have got this script to give effects to buttons which i have, it fails after the page is posted back, i have also put the code in a pageLoad method yet it still does not function. any idea how i can go about making this script run once the page has loaded.
$(document).ready(function () {
/*preloader for image loading bar*/
jQuery(function ($) {
function preLoad() {
//alert("script running");
$("#divQuestionMatrix").addClass("hidden");
}
function loaded() {
$("#divQuestionMatrix").removeClass("hidden");
$('div#preLoader').css({ display: 'none' }).remove();
}
preLoad();
window.onload = loaded;
});
/* End of preloader*/
$("#btnPrevious").click(function (e) {
$("#navigation").val("previous");
}
);
$("#btnNext").click(function (e) {
$("#navigation").val("next");
}
);
/* $(".qmatrix").click(function () {
//get id of button
alert($(this).attr('id'));
$("#navigation").val($(this).attr('id'));
}
);*/
$(".qmatrix").hover(function (e) {
//get id of button
//alert($(this).attr('id'));
//get src of image before hover
var origimage = $(this).attr('src');
// alert(origimage);
//$(this).attr({ src: 'images/questionMatrix/100' + $(this).attr('id') + '.png' });
$(this).stop().animate({ "opacity": "0.1" }, "fast")
},
function () {
// $(this).attr({ src: '' + origimage.toString() + '' });
$(this).stop().animate({ "opacity": "1" }, "fast");
}
);
The document.ready event is fired once the page has finished loading.
Inside the handler for the ready event, you're then using the ready event shortcut (passing a function directly to the global jQuery function (which is the same as the global $ function btw) to add another handler function for the ready event.
Inside this second ready handler you're then trying to assign the loaded function to window.onload, which would have already fired by this point.
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>
Put this Latest Jquery Library Just just above to your document.ready() function and try to run your program.
<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();
});
});
I have two elements that shouldn't be active at the same time, so when one is toggled I fade the other out, however I would like to be able to fade the open element out and then bring the other one in. Is there a way to do this that isn't a hack?
<script ="text/javascript">
$(function() {
$('#jlogin').click(function() {
$('#login').toggle('fast');
$('#reg').fadeOut('fast');
});
$('#jreg').click(function() {
$('#reg').toggle('fast');
$('#login').fadeOut('fast');
});
});
</script>
That is my current script.
Look at using the callback mechanism for fadeOut so you can chain the animations. The callback on the animation methods are called after the previous animation is complete.
<script type="text/javascript">
$(function() {
$('#jlogin').click(function() {
$('#reg').fadeOut('fast', function() {
$('#login').toggle('fast');
});
});
$('#jreg').click(function() {
$('#login').fadeOut( 'fast', function() {
$('#reg').toggle('fast');
});
});
});
</script>
