So I don't get why this isn't working. I want to show a Div when another div has a value. I got this code from stackoverflow and it's pretty simple. But it doesn't work for me. No console errors..
$(document).ready(function(){
if ($(".txt").html().length > 0) {
$('.btn-01').show();
}
});
If the html value of .txt is larger then 0 then show btn-01.
But it doesn't. In my web inspector it just says:
<div style="display: block;" class="btn-01"><p>Things</p></div>
If I remove the script it says:
<div class="btn-01"><p>Things</p></div>
So it does do something. I tried changing the show to hide. But no go.
<div style="display: none;" class="btn-01"><p>Things</p></div>
I tried:
$(document).ready(function(){
if ($(".txt").html().length > 0) {
$('.btn-01').addClass('showme);
}
});
btn-01 css:
.btn-01 {
background: #f60;
color: #fff;
border-radius: 2px;
padding: 5px;
text-align: center;
margin: 40px auto 0px auto;
width: 90%;
}
But that didn't work either. Does anyone know whats going on here?
Maybe I should work with an else statement? Help would be much appreciated.
JsFiddle
You need to either set the button to display none prior to the window loading or add an "else" statement to hide the element:
.btn-01{
display:none;
}
OR
$(document).ready(function(){
if ($(".txt").html().length > 0) {
$('.btn-01').show();
}
else
{
$('.btn-01').hide();
}
});
See the fiddle: https://jsfiddle.net/r89gg7tp/
IMPORTANT TO CONSIDER
If you have entered a line break between the starting and closing tags of the element, this will add to the length. You need to set the txt div to be in the following format:
<div class='txt'></div>
It may be better to change your function to this:
$(document).ready(function(){
if ($(".txt").html().trim(' ').length > 0) {
$('.btn-01').show();
} else {
$('.btn-01').hide();
}
});
This way you trim the whitespace before checking.
See the second fiddle: https://jsfiddle.net/r89gg7tp/3/
You need to hide the btn-01 with a "display:none" in the stylesheet and then execute your script.
I think you are having a "display:none !important" which is overriding the jquery show() function inline style.
This might help you.
$(document).ready(function(){
if (!$.trim($(".txt").html())){
$('.btn-01').addClass('showme');
}
});
Please let me know if you've any queries.
You can use .contents() with .toggle():
$(document).ready(function() {
$('.btn-01').toggle($(".txt").contents().length > 0);
});
.btn-01{display:none;}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="txt">
<h3>Things Title</h3>
</div>
<div class="btn-01">
<p>Things</p>
</div>
You guys where all right. I needed to place the code in some Session file (Ajax). Now its working with the original code and even some that you provide.
Thanks!

Thanks for taking a look at my question.
I'm trying to be able to hover over portfolio items but I need to loop through them using each() because I need some way of identifying each item.
I'm trying to hover over .recent-work-item to show .recent-work-item__overlay the .show-none class does display:none;
Neither the hover nor the on.("mouseenter", function(){}) is working.
Here is the HMTL:
<section class="recent-work-item" data-portfolio-id="rwi-<?php echo $i;?>">
<div class="recent-work-item__overlay show-none">
<h3 class="color-white bolder-font"><?php the_title(); ?></h3>
VIEW CASE
</div>
<div class="recent-work-img">
<img src="<?php echo get_template_directory_uri();?>/assets/img/work1.jpg" class="portrait">
</div>
Here is the jQuery:
$.each($('.recent-work-item'), function(){
var thisid = $(this).attr("data-portfolio-id");
console.log(thisid);
$("[data-portfolio-id="+"'"+thisid+"']").on('mouseenter', function(){
$(thisid).find('.recent-work-item__overlay').removeClass('show-none');
});
$("[data-portfolio-id="+"'"+thisid+"']").on('mouseleave',function(){
$(thisid).find('.recent-work-item__overlay').addClass('show-none');
});
});
This is not working, I can't get the hover to work and all I want to do is add or remove a class, can I not do this in each().
I've researched thoroughly in StackOverflow but can't find an answer. I would REALLY appreciate any help I can get on this.
I have test your code in my codepen, and the problem you should use $(this) than use $(thisid)
$.each($('.recent-work-item'), function(){
var thisid = $(this).attr("data-portfolio-id");
$("[data-portfolio-id="+"'"+thisid+"']").on('mouseenter', function(){
$(this).find('.recent-work-item__overlay').removeClass('show-none');
});
$("[data-portfolio-id="+"'"+thisid+"']").on('mouseleave',function(){
$(this).find('.recent-work-item__overlay').addClass('show-none');
});
});
Here look at my codepen
Here I have added an example that shows how you could use CSS to show/hide elements. It might not give you exact answer to your problem, but it will help you change your stylesheets as per your requirement.
Essentially, as per the discussion in comments, I don't think you need javascript to design the page the way you need it.
.container {
padding: 10px;
border: 1px solid gray;
}
.container > .hideOnHover {
display: block;
}
.container > .showOnHover {
display: none;
}
.container:hover > .hideOnHover {
display: none;
}
.container:hover > .showOnHover {
display: block;
}
<div class="container">
<div class="hideOnHover">
This text will be hidden on hover.
</div>
<div class="showOnHover">
This text will be shown on hover.
</div>
</div>
i need help getting this to work, tried everything google had to offer.. but still stuck. what i need it to do is load the value of (div id="availablecredits") to (div id="beta") on click. can any body help me out?
onclick="javascript:document.getElementById('beta').value=(javascript:document.getElementById('availablecredits').value)"
i also tried onclick="javascript:document.getElementById('beta').value=('#availablecredits')"
The property value is common for input elements like <input>, <select>, <textarea> and <button>
I think what you want is to copy a content of a <div> element to another div. If it's the case, use innerHTML instead of value.
Here is a snippet, just click on the gray area.
#div-two {
min-height: 20px;
background: #CCC;
}
<div id="div-one">
Hello this is #div-one
</div>
<div id="div-two" onclick="document.getElementById('div-two').innerHTML=document.getElementById('div-one').innerHTML"></div>
SNIPPET #2
You've defined a third <div> which you use as trigger but you can't click it if it's not visible, because it's height is 0. Specify some text inside it, then it's visible and the JS part work. Take a look at the snippet.
#getCredits {
background: #CCC;
}
<div id="beta">0.00</div>
<div id="availablecredits">500</div>
<div id="getCredits" onclick="document.getElementById('beta').innerHTML=document.getElementById('availablecredits').innerHTML">Click here to get available credits</div>
SNIPPET #3 - jQuery
$('#getCredits').click(function() {
$("#beta").html($('#availablecredits').html());
});;
#getCredits {
background: #CCC;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="beta">0.00</div>
<div id="availablecredits">500</div>
<div id="getCredits">Click here to get available credits</div>
Simple javascript function, change the ids in the function call to those of the elements in question.
<script>
function set_value( src,tgt ){
document.getElementById( tgt ).innerHTML=document.getElementById( src ).innerHTML;
}
</script>
<style>.p5{ display:block; padding:1rem; margin:1rem; border:1px solid black;}</style>
<div class='p5' id='src_div' onclick="set_value('src_div','tgt_div')">Weebles wobble but they don't fall down!</div>
<div class='p5' id='tgt_div'></div>
Or you can use a link to set the value
you should try to avoid writing inline event.try this:
<style>
#getCredits {
background: #CCC;
}
</style>
<div id="beta">0.00</div>
<div id="availablecredits">500</div>
<div id="getCredits">Click here to get available credits</div>
<script>
document.getElementById('getCredits').addEventListener("click",function(){
document.getElementById('beta').innerHTML=document.getElementById('availablecredits').innerHTML;
});
</script>
Why inline css and javascript are bad:http://robertnyman.com/2008/11/20/why-inline-css-and-javascript-code-is-such-a-bad-thing/
The .val() method is sometimes useful:
var input = $("#Input").val();
I have a parent <div>, #amwcontentwrapper, which has a series of divs within it with their own classes and ids.
I want to use jQuery to select these child divs, and IF they have the class .amwhidden, do nothing, but if not, remove the .amwshown class and add the .amwhidden class.
This is what I have so far, but it is not working. I think it may be my selecting of the child divs within the parent.
Can anybody see any obvious problems? Thanks for your help.
if ($('#amwcontentwrapper > div').hasClass('amwhidden')){
} else {
$('#amwcontentwrapper > div').fadeIn(600, function(){
$('#amwcontentwrapper > div').removeClass('amwshown');
$('#amwcontentwrapper > div').addClass('amwhidden');
});
}
And here is the basic html that I am using:
<div class="amwshown" id="amwintro">
Intro Section, which should have the 'amwshown' class removed, and the
'amwhidden' class added, when the jQuery runs. Currently, this does not happen.
</div>
UPDATE: Using War10ck's solution in the comments below (i.e. $('#amwcontentwrapper > div.amwshown')) I have managed to get the classes changing as I wished. However, those which have had the .amwshown class removed and .amwhidden class added still show on the page, despite the CSS looking like this:
.amwhidden {
display:none;
}
.amwshown {
display:block;
}
Looking at the Dev Tools, it seems that, when the jQuery is run (on a click event) the classes are changing, but any classes which are having the .amwshown class added (thus displaying them on the page) are also having the a <style> tag added to them which makes them display:block;
When I then press another button, which should hide the aformentioned <div> to make way for another one, the class is being changed to .amwhidden, but that <style> tag is not being deleted, so even though it has the .amwhidden class, it is still on the page.
I've created a JSFiddle here, if anybody still wants to help!

$('#buybutton').click(function() {

`
You can use not to remove the elements you do not want, like this:
$('#amwcontentwrapper > div').not('.amwhidden')
.removeClass('amwshown')
.addClass('amwhidden');
And work with that.
Try this
$(document).ready(function() {
$("#amwcontentwrapper").children().each(function(elem, x) {
if ($(x).attr("class") == "amwhidden") {
alert($(x).attr("class"));
$(x).removeClass("amwhidden").addClass("amwshow");
alert($(x).attr("class"));
}
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.0/jquery.min.js"></script>
<div id="amwcontentwrapper">
<div class="amwhidden"></div>
<div></div>
<div></div>
</div>
You can try each as follow,
$("#amwcontentwrapper div").each(function(){
if($(this).hasClass('amwhidden'))
//DO something
else
//DO something
});
Thank you for all help, it has prompted some brainstorming which has solved this issue.
Instead of adding the .amwhidden class and removing the .amwhidden class using jQuery, I have just created a .amwsection class, which all the sections belong to which has an initial display value of none. So far, so good; all of the sections are not there when you load up the page.
Then I use the .css jQuery function to change the display:none to display:block when the corresponding button is clicked, and changing all other .amwsections to display:none. This works just fine, but the effect is quite abrupt; there is no fading in, as you would get if you used the .animate function. .animate, however, does not work with the display value.
.fadeOut and .fadeIn to the rescue! By wrapping the .css change in these, I can create a fading in/out effect and can still use the display value.
Here is one example of this code.
The #buybutton is the button to be pressed.
#amwintro is just something which appears when the page loads - it will now be set to display:none if this is the first button pressed.
The .amwsection are all of the hidden sections. This portion of the code just resets all of them. This and the #amwintro section happen very quickly (1/100th of a second) to keep response time good.
The #amwbuy is the specific section that I want to reveal. As you can see, this fades in over a longer period.
Currently only tested in Chrome, but I think I've got it!
$(document).ready(function () {
$('#buybutton').click(function() {
$('#amwintro').fadeOut(1, function() {
$(this).css({
display:'none',
});
});
$('.amwsection').fadeOut(1, function() {
$(this).css({
display:'none',
});
});
$('#amwbuy').fadeIn(600, function() {
$(this).css({
display:'block',
});
});
});
});
I need a div to show when days remaining is less than 0
i have this working on jsfiddle
but when i try open this anywhere else it wont run
if ($('.daysrem').html() >= 0) {
$("#warningexp").hide();
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<div class="daysrem">3</div>
<br>
<div id="warningexp"><span style="background-color: red; padding: 10px; color:white; font-size:16px"><b>MEMBERSHIP EXPIRED</b></span>
</div>
According your div match as lonic said and like it does on your jsfiddle, you may have forget the document.ready()
$( document ).ready(function() {
if ($('.daysrem').html() >= 1) {
$("#warningexp").hide();
}
});
Well it's easy. Your code point to a classname .daysrem. Your HTML instead has a class .days_remaining. They just don't match. Additionally your code points to hide a div with the id #warningexp, in your HTML instead you have a div with #expired. You need to take care of those classes and id's. If your jQuery code don't match with them, it just can't work.
Try this instead:
if ($('.days_remaining').html() >= 0) {
$("#expired").hide();
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<div class="days_remaining">3</div>
<br>
<div id="expired"><span style="background-color: red; padding: 10px; color:white; font-size:16px"><b>MEMBERSHIP EXPIRED</b></span>
</div>
I think it should be:
if ($('.daysrem').text() >= 0) {
$("#warningexp").hide();
}
Hope this helps.
To change selector so it only show/hides when i click the image i put spoiler/ popdown menu directly after .OS image. Right now the popdown is a child of the .OS container, so clicks on it are passed to the .OS click handler.
But the code isn't perfect because when i click the 1st MAC both spoilers are opened.
But I want that spoilers are opened one at a time
But the main problem is that I can't fix the javascript code properly inside these types of spoilers (dokuwiki class) inside <td> tags:
This is the javascript code I use :
<div class="dokuwiki">
<div class="right_page">
<div class="entry-content">
<script type="text/javascript" src="./zzzz_files/jquery.js"></script>
<script type="text/javascript">
$(document).ready(function(){
$(".nonjs").removeAttr( "href"); //href is needed for users without JS
$('.OS').click(function(){
if($(".details").is(":visible"))
{
$(".details").not(":hidden").hide("slow");
return true;
}
else
{
$(".OS").not(this).each(function(i) {
$(".details").hide("slow");
});
$(".details").show("slow");
return false;
}
});
});
</script>
<style type="text/css">
<!--
.details {
display: none;
clear: both;
padding: 2px;
}
.nonjs{
cursor:pointer;
}
img {
border: 0px;
}
-->
</style>
I thought about doing a video to better explain the problem and provide the local version of files for testing code:
Thanks in advance
This code works:
$(document).ready(function(){
$(".nonjs").removeAttr( "href");
//href is needed for users without JS
$('.OS').click(function(e){
if(!$(e.target).parents('.details').length){
if($(this).find('.details').is(":visible"))
{
$(this).find('.details').not(":hidden").hide("slow");
return true;
}
else
{
$(this).find('.details').show("slow");
return false;
}
}
});
});
I don't know what you're asking but here is what I think you want:
When clicking on an image, show the details below it and hide all others. If the details are already visible, hide them. Clicking something inside the details should not affect anything.
Demo
$(document).ready(function(){
$(".nonjs").removeAttr( "href"); //href is needed for users without JS
$('.OS').click(function(){
var details = $(this).next(".details");
$(".details").hide("slow");
if(details.is(":hidden")) {
details.show("slow");
}
});
});
