I'm trying to hide <img> if the source is empty. But I have no luck.
I found few posts here, but it doesn't work for me.
Here is my code, it's table based because it will be a template:
Images:
<td width="92%" align="center" class="imagenes_desc">
<img class="imagen" src="http://webs.ono.com/norfolk/ebay/images/01.jpg" width="800">
<img class="imagen" src="" width="800">
<img class="imagen" src="" width="800">
<img class="imagen" src="" width="800">
<img class="imagen" src="" width="800">
<img class="imagen" src="" width="800">
<img class="imagen" src="" width="800">
<img class="imagen" src="" width="800">
<img class="imagen" src="" width="800">
<img class="imagen" src="" width="800">
</td>
Here is the Javascript I'm trying to implement.
<script type="text/javascript">
$(document).ready(function(){
if ($(".imagen").attr(src="") == "") {
$(".imagen").hide();
}
else {
$(".imagen").show();
}
</script>
I'm not very familiar with JS, I found this script here on Stackoverflow, but I can't get it to work.
Update
Trying this, but doesn't work (Chrome hides well, but Firefox and IE don't):
<script type='text/javascript' src='http://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js'></script>
<script type="text/javascript">
$("imagen").each(function(){
if ($(this).attr("src") == "")
$(this).hide();
else
$(this).show();
});
</script>
<style>
.hide {display:none !important;}
.show {display:block !important;}
</style>
Thanks,
You can just use CSS for this:
img[src=""] {
display: none;
}
<img src="">
<img src="http://dreamatico.com/data_images/kitten/kitten-2.jpg">
How about using jQuery's attribute selectors?
$(document).ready(function(){
$('.imagen[src=""]').hide();
$('.imagen:not([src=""])').show();
});
Working example here
Your logic is flawed.
if ($(".imagen").attr(src="") == "") {
$(".imagen").hide();
}
else {
$(".imagen").show();
}
This will not work, as you've got iterate through each instance of .imagen
$('.imagen').show().filter(function(){
return $(this).attr('src') == '';
}).parents('a').hide();
Above, we show all the .imagen's, then filter based on their src attribute, then hide the one's we're left with.
As a side point, you may want to hide the parent <a> element, rather than the image.
Just put space inside alt tag.Here is working code
<img class="imagen" src="" width="800" alt" ">
I am surprised that you don't have some kind of syntax error
And you're code is also wrong, because it does not test every instance of .imagen.
Do it like this
$(".imagen[src='']").hide();
You have wrong syntax for getting value of src by attr()
Change
if ($(".imagen").attr(src="") == "") {
To
$(".imagen").each(function(){
if ($(this).attr("src") == "")
$(this).hide();
else
$(this).show();
});
In your stylesheet make add the following code to define a "hidden" class:
.hidden {
display: none;
}
Then add the following javascript code:
$(document).ready(function() {
$(".imgagen").each(function() {
var atr = $(this).attr("src");
if(atr == "") {
$(this).addClass("hidden");
} else {
$(this).removeClass("hidden");
}
});
});
test for src attribute if its null, but anyway - if you hide images what happens to the wrapping A elements? Rather, dont generate A/IMG elements for those not having any image.
Your code that you have posted should work but make sure that u have added the jquery library files on the header of ur html page .
go to jquery site and then download the js file. then add the following line on HTML page section head :

I'm trying to hide images without the src in WordPress.
Following is the image code displaying on the front end
<img src="[custom-gallery-image-01]" class="galimage" height="300" width="580"/>
JS used to hide the image
<script type="text/javascript">
$(document).ready(function() {
$(".galimage").each(function() {
var atr = $(this).attr("src");
if(atr == "") {
$(this).addClass("hidegalimage");
} else {
$(this).removeClass("hidegalimage");
}
});
});
</script>
CSS
.hidegalimage {
display:none;
}
But I can still see the broken image icon & an image border. View JSFiddle. Can someone fix my issue or give me a suggestion how to hide the image?
Many thanks
Much more elegant to use CSS instead, no Javascript required, assuming the bad srcs start with [ as in your HTML: are empty strings:
.galimage[src=""] {
display:none;
}
<img src="https://www.gravatar.com/avatar/b3559198b8028bd3d8e82c00d16d2e10?s=32&d=identicon&r=PG&f=1" class="galimage" height="300" width="580"/>
<img src="" class="galimage" height="300" width="580"/>
<img src="https://www.gravatar.com/avatar/b3559198b8028bd3d8e82c00d16d2e10?s=32&d=identicon&r=PG&f=1" class="galimage" height="300" width="580"/>
Using jquery
$("img").error(function(){
$(this).hide();
});
Or
$("img").error(function (){
$(this).hide();
// or $(this).css({'display','none'});
});
no need for CSS alternative
You can use this but this is not hidding its removing from the page at all (DOM):
<img id='any' src="https://invalid.com" onerror="document.getElementById(this.id).remove()" >
I was looking for a way to change image A to B and B to A by just
clicking them.
So far, this is what I'm using.
<img id="pixelbutton" src="images/pixelbutton.png" />
<img id="pixelbutton2" src="images/pixelbutton_press.png" style="display: none;" />
<script type="text/javascript">
$(document).ready(function(){
$("#pixelbutton").click(function(){
$("#pixelbutton").css({'display':'none'})
$("#pixelbutton2").css({'display':'block'});
})
$("#pixelbutton2").click(function(){
$("#pixelbutton2").css({'display':'none'})
$("#pixelbutton").css({'display':'block'});
})
})
</script>
The script works well for a pair of image.
Now if I have 100 pair of image.
"A <--> B"
"C <--> D"
"E <--> F"
and so on...
Do I have to copy the body HTML and script 100 times and change their ID+URL or there is another more efficient way?
To create hundreds of them... First, use a class.
Then, use a data attribute to store the "alternate" URL.
<img class="pixelbutton" src="images/pixelbutton.png" data-altsrc="images/pixelbutton_press.png"/>
<script type="text/javascript">
$(document).ready(function(){
$(".pixelbutton").click(function(){
// Get the two values
var src = $(this).attr("src");
var altSrc = $(this).data("altsrc");
// Switch them
$(this).attr("src",altSrc).data("altsrc",src);
});
})
</script>
This will work for thousands of .pixelbutton...
;)
EDIT
As per this other .data() documentation, (I wonder why there's two different documentation pages...) the data-* have to be lowercase... Because when trying to get altSrc, it is interpreted as alt-src.
I just learned that... That is quite a strange new standard, from jQuery 3.
So here is your CodePen updated.
You could probably set a naming pattern and use delegation to make an event handler on the images' container.
You could check if the event's target is an image and retrieve its id. Using that id, you could use the pattern you've set to change the images interchangeably.
There are multiple solutions to this, but this is by far the simplest approach:
Wrap your image pairs in a parent <div>
Use .toggleClass() to toggle a class, say .hide, in the images in the element
This solution assumes that you have images in pairs :) see proof-of-concept example:
$(document).ready(function() {
$('img').click(function() {
console.log($(this).siblings());
$(this).add($(this).siblings()).toggleClass('hide');
});
});
/* For layout only */
div {
display: inline-block;
}
/* Used to hide image */
.hide {
display: none;
}

Try this one:
jQuery(document).ready(function($) {
var $imgBlock = $('#images');
var html = '';
var imgArr = [
'http://i0.wallpaperscraft.com/image/surface_shape_metal_116716_200x300.jpg',
'http://i0.wallpaperscraft.com/image/universe_space_face_rocket_116714_200x300.jpg',

];
$.each(imgArr, function(index, url) {
html += (index % 2 === 0) ? '<div>' : '';
html += '<img src="' + url + '"/>';
html += (index % 2 === 1 || index === imgArr.length - 1) ? '</div>' : '';
});
$imgBlock.append(html);
$imgBlock.on('click', 'img', function(e) {
$(this).parent('div').find('img').removeClass('red');
$(this).addClass('red');
});
});
img {
border: 2px solid #ccc;

.red {
border: 2px solid red;

<div id="images"></div>
I have a div with content ie. short-code, images, links etc.
I need my switch to toggle the div container without jquery. I have spend days and would really appreciate some assistance.
I have included the switch code. On off the div must be display.style="none"
html
<img id="switch" onclick="changeImage()" src="http://designplatform.byethost15.com/on.png" width="60" height="150">
JavaScript
<script>
function changeImage()
{
element=document.getElementById('switch');
if (element.src.match("off"))
{
element.src="http://designplatform.byethost15.com/on.png";
}
else
{
element.src="http://designplatform.byethost15.com/off.png";
}
}
</script>
You can accomplish this using jquery.
Add jquery to your html:
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
Take out the onclick=changeImage() function from the <img> element, and add the following jquery(found in the first part of the snippett) into your <script> tags on your html.
$(function () {
$("#switch").click(function () {
if ( $("#switch").val()=="off")
{
$("#switch").attr("src","http://designplatform.byethost15.com/on.png");
$("#switch").val("on");
}
else
{
$("#switch").attr("src","http://designplatform.byethost15.com/off.png");
$("#switch").val("off");
}
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<img id="switch"
src="http://designplatform.byethost15.com/on.png" width="60" height="150">
Essentially I have an interactive map which contains 4 div statements each of which contains an image of an island. I would like to create an on hover event which will display a corresponding sailing timetable depending on which image the user hovers. e.g. island 1 should display timetable 1.
I have the following code so far and ideally I am looking for a javascript or css solution:
<div class="Map">
<div id="Island_Morar">
<img src="images/IsleOfMorar.jpg"/>
</div>
<div id="Island_Rum">
<img src="images/IsleOfRum.jpg"/>
</div>
<div id="Island_Eigg">
<img src="images/IsleOfEigg.jpg"/>
</div>
<div id="Island_Muck">
<img src="images/IsleOfMuck.jpg"/>
</div>
</div>
<img id="TimetableEigg" src="images/TimetableEigg.jpg">
any help is appreciated.
You need some different markup if you want a plain css solution. If you want to have different timetables for each hover you should go with something like this:
markup
<div class="tt-container" id="Island_Rum">
<img src="images/IsleOfRum.jpg"/>
<img class="timetable" src="images/TimetableRum.jpg">
</div>
<div class="tt-container" id="Island_Eigg">
<img src="images/IsleOfEigg.jpg"/>
<img class="timetable" src="images/TimetableEigg.jpg">
</div>
<div class="tt-container" id="Island_Muck">
<img src="images/IsleOfMuck.jpg"/>
<img class="timetable" src="images/TimetableMuck.jpg">
</div>
</div>
css
.timetable {
display : none;
}
.tt-container:hover .timetable {
display : block;
}
That should do the trick
If you want to keep your current HTML code, I'd make three image blocks for timetables, and initially set them all to display: none; and add onmouseover event handlers to island elements which would contain Javascript statement which will set disply: block; on appropriate timetable.
Something like this:
<div class="Map">
<div id="Island_Morar" onmouseover="document.getElementById('TimetableEigg1').style.display = 'block';">
<img src="images/IsleOfMorar.jpg"/>
</div>
<div id="Island_Rum" onmouseover="document.getElementById('TimetableEigg2').style.display = 'block';" >
<img src="images/IsleOfRum.jpg"/>
</div>
<div id="Island_Eigg" onmouseover="document.getElementById('TimetableEigg3').style.display = 'block';" >
<img src="images/IsleOfEigg.jpg"/>
</div>
<div id="Island_Muck" onmouseover="document.getElementById('TimetableEigg4').style.display = 'block';" >
<img src="images/IsleOfMuck.jpg"/>
</div>
</div>
<img id="TimetableEigg1" src="images/TimetableEigg1.jpg">
<img id="TimetableEigg2" src="images/TimetableEigg2.jpg">
<img id="TimetableEigg3" src="images/TimetableEigg3.jpg">
<img id="TimetableEigg4" src="images/TimetableEigg4.jpg">
Seems you barely know the basics of HTML and already trying to jump too deep. External libraries will help you and speed up your progress. I see people gave you CSS solutions so here is a JS solution.
First thing is download the well known JS library called jQuery.
then load this file to your page and add a script at the bottom of your body tag:
$("div.map").on("mouseover", "#Island_Morar", function(e) {
$(this).show(); // option one
//$(this).addClass("class-name"); // option two
}).on("mouseout", "#Island_Morar", function(e) {
$(this).hide(); // option one
//$(this).removeClass("class-name"); // option two
});
With this script you can do whatever you want, for example - use the second option of adding and removing classes in order to animate your Timetables (see Example).
Possible CSS / JQuery solution:
$(".Map a").hover(
function() {
$('#' + $(this).attr('class')).show();
}, function() {
$('#' + $(this).attr('class')).hide();
}
);
.timetables img { display:none; }
<div class="Map">
<a href="#" class="islandmorar">
<img src="images/IsleOfMorar.jpg"/>
</a>
<a class="islandrum">
<img src="images/IsleOfRum.jpg"/>
</a>
<a class="islandeigg">
<img src="images/IsleOfEigg.jpg"/>
</a>
<a class="islandmuck">
<img src="images/IsleOfMuck.jpg"/>
</a>
</div>
<div class="timetables">
<img id="islandmorar" src="images/TimetableEigg.jpg"/>
<img id="islandrum" src="images/TimetableEigg.jpg"/>
<img id="islandeigg" src="images/TimetableEigg.jpg"/>
<img id="islandmuck" src="images/TimetableEigg.jpg"/>
</div>
Pure CSS solution but you need to place the large image in .main div
the first image will be displayed first and will change on hover on other images and when you leave move out of the main div it will show the first image
Note: used random images
.Map > div {
display: inline-block;
}
img.two,
img.three,
img.four,
#Island_Rum:hover ~ img.one,
#Island_Muck:hover ~ img.one,
#Island_Eigg:hover ~ img.one {
display: none;
}
img.one {
display: block;
}
#Island_Morar:hover ~ img.one {
display: block;
}
#Island_Rum:hover ~ img.two {
display: block;
}
#Island_Eigg:hover ~ img.three {
display: block;
}
#Island_Muck:hover ~ img.four {
display: block;
}
<div class="Map">
<div id="Island_Morar">
<img src="http://placeimg.com/100/100/any/animals" />
</div>
<div id="Island_Rum">
<img src="http://placeimg.com/100/100/any/arch" />
</div>
<div id="Island_Eigg">
<img src="http://placeimg.com/100/100/any/nature" />
</div>
<div id="Island_Muck">
<img src="http://placeimg.com/100/100/any/tech" />
</div>
<img class="one" src="http://placeimg.com/400/400/any/animals" />
<img class="two" src="http://placeimg.com/400/400/any/arch" />
<img class="three" src="http://placeimg.com/400/400/any/nature" />
<img class="four" src="http://placeimg.com/400/400/any/tech" />
</div>
Don't put class="map" to the wrapper div, give it to every div with id beginning with "Island_...".
Do the same with your timeTable images, give them a class "timeTable".
Put this before your "head" end tag :
<script>
"use strict";
//wait for every element to be loaded
window.onload = function(){initialization();}
</script>
Then, put this before your "body" end tag :
<script>
"use strict";
//first create a function that hides elements with class 'timeTable'
function hide(elements){
var htmlClass = document.getElementsByClassName(elements);
//hide every element with class
for (var i = 0 ; i < htmlClass.length ; i++){
htmlClass[i].style.display = "none";
htmlClass[i].style.visibility = "hidden";
}
}
//create a function that show only the timeTable you want
function show(element){
document.getElementById(element).style.display = "block";
document.getElementById(element).style.visibility = "visible";
}
function initialization(){
//replace 'someMapId' with the id of the image you are hovering
//replace 'someTimeTableId' with the id of the image you want to show
//replace 'timeTable' with the name of a class you want to hide
document.getElementById("someMapId").onmouseover = function(){
hide("timeTable");
show("someTimeTableId");
}
//repeat these 3 lines for every image the user will hover
}
</script>
Don't forget the quotes when using the functions.
You should use css for styling and javascript for interactions.
You don't need jQuery for basic scripts like that, it only slows page loading and keeps you away from learning basic javascript.
(Ok, I edited mistakes, now it works ;)
jsFiddle
I have a page with various images tapered throughout.
I would like to use jQuery to find those that use video.jpg and wrap those images in a new <div>:
<img src="/images/thumb1.jpg" alt="no div" />
<img src="/images/video.jpg" alt="wrap me" />
<img src="/images/thumb2.jpg" alt="no div" />
Try the following code:
$("img[src$=video.jpg]").wrap("<div></div>")
I Made this Fiddle for you.
This should work for you.
$(document).ready(function(){
var images = $('[src="/images/video.jpg"]');
images.each(function() {
$(this).wrap('<div class="wrapper"></div>');
})
})
Try this:
$('img[src=*"video.jpg"]').wrap('<div></div>');
