Using javascript to hide div - javascript

I am using Javascript to hide a search box until a box is clicked. That works fine.
However when the page is first loaded, you can see the search box there and then it disappears once the page has fully loaded.
How can I make it hide and not show at all until my button is clicked..
This is the Javascript:
<script type="text/javascript">
$(function(){
$(".search").hide();
$(".clicktosearch").on("click", function(){
$(".search").slideToggle("600");
.search is the actual search box
.clicktosearch is the box the user must click for the actual search box to show up.
They only thing I have tried is to move the Javascript above the html box but, to no luck, now I am asking you all on SOF.

You need to use
display:none
in the CSS to hide it initially. The javascript only executes after the page has loaded so you will always see it briefly before the javascript kicks in.

This is what you need:
CSS
.search { display:none;}
JS
$(".clicktosearch").on("click", function(){
$(".search").slideToggle("600");
});
I removed $(".search").hide(); because it's unneeded and may cause other problems. (JQuery doesn't need to hide something that's already hidden via CSS.)
BTW: If there's only one element that matches .search, it should really be an id and so #search. Same goes for .clicktosearch.

Hide it using css .
.search { display:none;}
The reason for this happening is the javascript getting loaded after the css and HTML take affect.
Hide it using CSS, the time lag before the div hides will be less.

You have the .hide inside of document.ready, $(function(){ is short for $(document).ready(function() {
So just put it before the document.ready and it should work...
<script type="text/javascript">
$(".search").hide(); //moved this line too here
$(function(){
$(".clicktosearch").on("click", function(){
$(".searchr").slideToggle("600");
although, What I personally would prefer is just in your css hide it.
Like so,
.search { display: none; }

You'll have to touch the CSS.
.search {
height: 0px;
}
Then in your JavaScript:
$(".clicktosearch").on("click", function(){
$(".search").slideToggle("600");
});

Need "document.write" to only write inside a specific element, not overwrite the whole page [duplicate]

I'm very new with javascript.
I'm trying to create a tag using document.write (with Wordpress) to add a style that hides images before they are preloaded. I've had to resort to writing a Javascript style to hide the images before they are loaded via CSS. I don't want to actually write it into the CSS file incase the user has Javascript disabled and then the images would never show.
I'm trying to get this code to work:
jQuery(function($) {
document.write('<style type="text/css"> .preload img { display: none; } </style>');
$('#body-wrap').preloadThis();
});
But, it is just overwriting the whole page and making it go blank. How can I stop this? I want to add the tag to the without removing the page. Tried using 'return', no luck.
Sorry, I'm a novice. Thanks in advance.
Using document.write() after the page has finished loading implicitly calls document.open(), which creates a new page. You should generally avoid document.write() and stick to proper DOM creation techniques, or use jQuery's shorthand creation methods:
jQuery(function($) {
$('<style type="text/css"> .preload img { display: none; } </style>')
.appendTo("head");
$('#body-wrap').preloadThis();
});
I'm assuming you can't edit the HTML or CSS files that are loaded by the page to include this rule? If that's the case, and you want these styles applied before the page finishes loading, take `document.write()` out of the jQuery ready handler:
// write() before the document finishes loading
document.write('<style type="text/css"> .preload img { display: none; } </style>');
jQuery(function($) {
$('#body-wrap').preloadThis();
});
This will write the <style> tag immediately after the currently executing <script> tag. Hopefully, this is in your <head> element as <style> is invalid anywhere else, although all browsers should parse it OK either way.
You don't need to add <style> tag, you can just hide them with jQuery:
jQuery(function($) {
$('.preload img').hide();
$('#body-wrap').preloadThis();
});
Don't know how your preloadThis() function works, but I guess it loads images and removes .preload class from img container. If it indeed works like that, this code will not help you - images will stay hidden.

jQuery shows hidden content on refresh

I use this fancy little jQuery toggle on my site, works great. But now I have a little larger text area I want to hide, and therefore I've included it in another php file, but when the site opens\refreshes the content is briefly shown and then hidden? Have I done something wrong or does it simply not work right with includes in it ?
Show me?
<div class="content">
<?php include 'includes/test.php'?>
</div>
<script>
jQuery(document).ready(function() {
var par = jQuery('.content');
jQuery(par).hide();
});
jQuery('#toggleMe').click(function() {
jQuery('.content').slideToggle('fast');
return false;
});
</script>
Use css to hide it
.content{
display:none;
}
Also
var par = jQuery('.content');
is a jQuery object so don't need to wrap it again as
jQuery(par).hide();
Just use par.hide(); but in this case, when you will use css to hide the element, then you don't need this anymore.
That will happen. The document briefly shows all the HTML before executing the code in your ready handler. (It has nothing to do with the PHP include.) If you want an element hidden when the page loads, hide it using CSS.
#myElement {
display: none;
}
The toggle should still work correctly.
You just need to don't use jquery document ready function. just use style attribute.
Show me?
<div class="content" style="display:none">
<?php include 'includes/test.php'?>
</div>
<script>
jQuery(document).ready(function() {
jQuery('#toggleMe').click(function() {
jQuery('.content').slideToggle('fast');
return false;
});
</script>
If this information is sensitive/not supposed to be seen without access granted, hiding it with CSS will not fix your problem. If it's not, you can ignore all of this and just use CSS with a display: none property.
If the information IS supposed to be hidden:
You need to only load the file itself on-demand. You would request the data with AJAX, do a $('.content').html() or .append() and send the result back directly from the server to the browser using something like JSON.
You are using the "ready" function that meant it will hide the element when the document is ready (fully loaded).
You can hide it using css:
.contnet { display: none; }
how you render you site server side does not affect how the site is loaded on the browser, what affects it is how the specific browser chooses to load your javascript and html, what i would recommend is set the element to hidden with css, since that is applied before anything else. And keep you code as is, since the toggle will work anyways
You can also clean up the code a little bit.
<script>
$(document).ready(function(){
$('.content').hide();
$('#toggleMe').click(function(){
$('.content').slideToggle('fast');
});
});
</script>

jQuery slow reveal on page load

I am trying to do a slow reveal on a particular div with an id of 'contentblock' on page load. This is my first time trying to code something in jQuery and I continue to fail. The following is my latest attempt, but I'm a complete newbie to this and surprisingly google hasn't been a whole lot of help.
<script type='text/javascript'>
$(window).onload(function(){
$('#contentblock').slideDown('slow');
return false;
});
</script>
before that I also had the following instead of the window onload line above:
$(document).ready(function(){
But that didn't have any success either. Can someone help a jQuery newbie out?
First, you'll need to make sure the element is hidden (or it won't be shown, since it's already visible). You can do this in either CSS or JavaScript/jQuery:
#contentblock {
display: none;
}
Or:
$('#contentblock').hide();
If you use CSS to hide the element you need to be aware that the element will remain hidden in the event of JavaScript being disabled in the user's browser. If you use JavaScript there's the problem that the element will likely flicker as it's first shown and then hidden.
And then call:
$(window).load(function(){
$('#contentblock').slideDown('slow');
});
I've made two amendments to your jQuery, first I've changed onload to load and I've also removed the return false, since the load() method doesn't expect any value to be returned it serves no purpose herein.
For the above jQuery you can use instead:
$(document).ready(function(){
$('#contentblock').slideDown('slow');
});
$(document).ready(function(){
if($('#contentblock').is(':hidden'))
{
$('#contentblock').slideDown('slow');
}
});
if you have jquery added to your project and your div is display none ... something like this should work.

jQuery function in pure javascript

I'm one of those people who never was bother to learn JavaScript and went straight for jQuery.
I'm writing simple script to hide everything till page is fully loaded - and because my jQuery is loaded after html/css/images I planning to put small script in the header.
So in jQuery it would be
$('body').css('display','none');
Pure JavaScript:
document.body.parentNode.style.display = 'none';
But than:
$(window).load(function() { $('body').css('display', 'block').fadeIn(3000); });
Has not animation? Why?
What I'm trying to do:
#1 hide everything(body) with javascipt till everything is loaded (there is no jQuery at this state as is being loaded at the end)
#2 show everthing(body) with animation of fadding (with jQuery - as is loaded at this state)
Any help much appreciated.
Pete
The equivalent to
$('body').css('display','none');
is
document.body.style.display = 'none';
$('body') selects the body element, but document.body.parentNode obviously selects the parent of body.
And shouldn't it be just
$('body').fadeIn(3000);
?
I asked because I assumed you already got the code working with only jQuery. But apparently you haven't, so again, it has to be $('body').fadeIn(3000); only, otherwise you make the element visible immediately and there is nothing to animate anymore.
See a demo: http://jsfiddle.net/fkling/Q24pC/1/
Update:
$(window).load is only triggered when the all resources are loaded. This could take longer if you have images. To hide the elements earlier, you should listen to the ready event:
$(document).ready(function() {
// still don't know why you don't want to use jQuery.
document.body.style.display = 'none';
});
or hide the elements initially with CSS
body {
display: none;
}
To make sure that users with disabled JavaScript can see the page, you'd have to add
<noscript>
<style>
body {
display: block;
}
</style>
</noscript>
in the head after you other CSS styles.
Update 2
Seems that setting the CSS property directly causes problems in some browsers. But using $('body').hide() seems to work: http://jsfiddle.net/fkling/JaLZU/
I'm not that clear on what your question really is, but if I'm on the right track you don't need the .css('display', 'block') part for the animation. Get rid of that, so it's just $('body').fadeIn(3000); and the animation should work fine.

Javascript/Jquery alternative to "display:none"?

I have a menu that shows or hides content when you click menu items. The JQuery looks like this:
$(document).ready(function() {
$("#bioLink").click(function(){
$("#about").show(1000);
$("#portfolio, #contact, #expand").hide(1000);
}); // end bio-click
$("#portfolioLink").click(function(){
$("#portfolio").show(1000);;
$("#about, #contact, #expand").hide(1000);
}); // end portfolio-click
$("#contactLink").click(function(){
$("#contact").show(1000);
$("#about, #portfolio, #expand").hide(1000);
}); // end contact-click
}); // end ready
In an older version of the site, all content is hidden when the page first loads, with this CSS rule:
#about, #portfolio, #contact {
display:none;
}
That CSS now wreaks havoc with a carousel I have since installed in the portfolio section.
Is there something I can do with the script to hide the content upon loading? Given that the existing script doesn't interfere with the carousel, this could be a proper solution.
There's several options to hide content on a page.
display: none;
This is the one you're currently uses, which collapses content (i.e. the element doesn't take up any space on the page.
visibility: hidden;
This hides content, but doesn't collapse, so the element while not visible still takes up the same amount of space on the page (useful if you want to hide and show elements in a list or navbar without making things jump back and forth).
opacity: 0;
Similar to visibility hidden, but still allows a user to trigger events or tab to the element.
There's a couple others, but these are the main three that would be useful. Would you mind elaborating on the wreaking havoc part? It's a bit difficult to provide you with the right tools given the problem is a bit vague.
Simply initialize the content IDs to be initially hidden on document load like this:
$( document ).ready(function() {
$( "#about, #portfolio, #contact" ).hide();
});
Then let the conditional script follow this to show and hide as ordered by the click event. Initializing the hide allows for other things to work without your script trying to run at the same time. <-- not sure if I explained that correctly
