</a>
</li>
How can I change image after page reload?
Thanks in advance.
url = "cardcatagory.php";
$(location).attr('href', url);
The code above redirect your page to another link. Try below.
$(document).ready(function () {
$("#quizcatagory").click(function () {
d = new Date();
$("#cards").attr("src", "http://ifliptips.com/admin/VueGuides/images/ifliptips_hover.jpg?timestamp=" + new Date().getTime());
$("#tips").attr("src", "http://ifliptips.com/admin/VueGuides/images/iflipcards.jpg");
$("#registeruser").attr("src", "http://ifliptips.com/admin/VueGuides/images/reg_users.jpg");
return false;
});
});
You are already setting the image with a PHP variable
<img id="cards" style="padding-top:15px" width=70 height=18 src=<?php echo $path; ?> />
Just change the image on the server side. Unless you are speaking of the image urls in the JavaScript, then you can either make their values PHP variables and set that from the server or you can create a PHP file that returns an image and put all the necessary logic to determine what image to display from there.

I have this code:
<div class="menuList">
<li><img src="/images/icon/arena.png" alt="">Arena<span class="green"> (+)</span>
</li>
</div>
And i want to remove <span class="green"> (+)</span> after users click that link.
Anyone can help me (php code)?
As already mentioned, PHP is not the ideal language to do this in. But, if you need to use PHP, here is how you could do it.
Set a session variable on the /arena/ page, like this;
<?php
session_start();
$_SESSSION['visited'] = 1;
?>
Then, use PHP to check for the session variable in your HTML code like this:
<div class="menuList">
<li><a href="/arena/"><img src="/images/icon/arena.png" alt="">Arena
<?PHP
If(isset($_SESSION['visited'])){
echo '<span class="green"> (+)</span>';
}
?>
</a>
</li>
</div>
You will need to add session_start() to the top of the page wherever you are accessing session variables, before you output anything to the page (e.g. DOCTYPE declaration.)
in Jquery you may do this like
<script>
$(function(){
$('.menuList').find('a').click(function(){
$(this).children('.green').remove();
});
});
</script>
You can accomplish this by adding this javascript to your page:
<script>
window.onload = function() {
var a = document.querySelector('.menuList a');
a.onclick = function() {
var span = a.querySelector('.green');
a.removeChild(span);
}
}
</script>
OR if you're using jQuery:
<script>
$(document).ready(function(){
$('.menuList').find('a').click(function(){
$(this).find('.green').remove();
});
});
</script>
There's a lot of examples about how to reload captcha image on clicking, they all have a 'captcha.php' as the image source, e.g.
<img id="captcha" src="captcha.php">
<a id='reload'>Refresh now</a>
$('#reload').click(function(){
$('#captcha').attr('src','captcha.php')
})
The image source in OpenCart in my form is
<img id="captcha_img" src="index.php?route=information/contact/securimage" alt="CAPTCHA Image" />
If I do this:
<script>
$(function() {
$('#captcha_img').click(function(){
$('img').attr('src', '<?php echo "index.php?route=information/contact/securimage" ?>?' + (new Date).getTime());
});
});
</script>
The first image loads, but when I click on the image, the new image doesn't load. Looks like I'm not specifying the correct URL. What path do I need to set in the script in OpenCart? Thank you.
<script>
$(function() {
$('#captcha_img').click(function(){
$(this).attr('src', '<?php echo "index.php?route=information/contact/securimage" ?>&time=' + (new Date).getTime());
});
});
</script>
Is that works?
I'm building a website where the admin can make settings for the website. I would like the admin settings page to have a similar "feel" as the rest of the website, which has some nice looking jQuery features.
On the admin site there's a hidden div, which is shown when one of six links has been clicked. I'd like the content of the hidden div to change content before showing itself. I'm not sure how to do this. I could have a div box for every link on the page. But this becomes pretty cumbersome since I'd need to repeat my css and jquery for every link. I imagine that this, somehow, can be done with some javascript/jquery code that determines which link that was click and then decides which php function to call inside the hidden div. Then the php could "echo" out the content of the div, which then could be shown.
How could one do this?
My HTML/jQuery code is as follows:
--- The html links ---
<table id="settings">
<tr>
<td>
<img src="images/folder.gif" alt="" height="100"/>
</td>
<td>
<img src="images/folder.gif" alt="" height="100"/>
</td>
<td>
<img src="images/folder.gif" alt="" height="100"/>
</td>
----- The Hidden div -----
<div id="dashboard_box">
<div class="dashboard_inside">
<form action="#" method="post">
<p style="font-size:20px; font-weight: bold;">Change color</p>
</br>
<fieldset>
<? load_content1();?>
</fieldset>
</form>
</div>
</div>
---- jquery code (working)----
var mouse_is_inside = false;
$(document).ready(function() {
$(".action").click(function() {
var loginBox = $("#dashboard_box");
if (loginBox.is(":visible"))
loginBox.fadeOut("fast");
else
loginBox.fadeIn("fast");
return false;
});
$("#dashboard_box").hover(function(){
mouse_is_inside=true;
}, function(){
mouse_is_inside=false;
});
$("body").click(function(){
if(! mouse_is_inside) $("#dashboard_box").fadeOut("fast");
});
});
You probably want to use ajax to load the content from the server. Take a look at jquery's .load() method: http://api.jquery.com/load/
You could include a data attribute per link:
<a class="action" data-content="content.php?method=load_content1"></a>
<a class="action" data-content="content.php?method=load_content2"></a>
js would look something like this:
$(".action").on('click', function() {
$("#dashboard_box fieldset").load($(this).data('content'), function() {
var loginBox = $("#dashboard_box");
if (loginBox.is(":visible"))
loginBox.fadeOut("fast");
else
loginBox.fadeIn("fast");
}
return false;
});
Then, in your content.php file you could check the method parameter in the url to determine what content to return.
My php is a little rusty, but something like this:
<?
call_user_func($_GET['method']); // i'm not sure how safe this is. you may want to be more explicit
?>
You can just add data attribute in each of your link's
<a href="#" data-url="content1.php" ..
Then on click of any of the a you can get the php to be called.
$('a').on('click',function(){
var phpFunctionToCall = $(this).data('url');
});
You probably need to make ajax call to load content into your fieldset As this <? load_content1();?> run's on server and javascript have no control over it.
Thanks for all the help. this is what I ended up doing.
--- HTML ---
<a class="action" data-content="content.php?method=load_content2"></a>
---Jquery---
var mouse_is_inside = false;
$(document).ready(function() {
$(".action").click(function() {
var phpFunctionToCall = $(this).data('content');
$('#indhold').load(phpFunctionToCall);
var loginBox = $("#dashboard_box");
if (loginBox.is(":visible"))
loginBox.fadeOut("fast");
else
loginBox.fadeIn("fast");
return false;
});
$("#dashboard_box").hover(function(){
mouse_is_inside=true;
}, function(){
mouse_is_inside=false;
});
$("body").click(function(){
if(! mouse_is_inside) $("#dashboard_box").fadeOut("fast");
});
});
--- PHP (shortened)---
function load_settings_panel($settingOnRequest) {
return $settingOnRequest;
}
$result = call_user_func('load_settings_panel', $_GET['method']);
echo($result);
I have a function in jquery which displays images on link click and also has to hide the image when the link is clicked again.
This is the code:
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.7/jquery.min.js"></script>
<script>
var $j = jQuery.noConflict();
$j(document).ready(function(){
$j('.links').click( function(){
var linkclicked = this.id;
var url = $j(this).attr('href'),
image = new Image();
image.src = url;
image.onload = function () {
$j('#image-holder'+linkclicked).empty().append(image);
/* The above line shows the image on first click.
Adding slideToggle hides the image again */
};
image.onerror = function () {
$j('#image-holder'+linkclicked).empty()
.html('That image is not available.');
}
$j('#image-holder'+linkclicked).empty().html('Loading...');
return false;
});
});
function loadnow() {
}
</script>
</head>
<body>
<?php $topicid=1; ?>
<a href="myimages/red-brick-wall-texture.jpg" class="links" id="<?php echo $topicid; ?>" >Show image</a>
<div id="<?php echo 'image-holder'.$topicid; ?>"></div>
<?php $topicid=2; ?>
<br><a href="/myimages/gymicon.JPG" class="links" id="<?php echo $topicid; ?>" >Show image</a>
<div id="<?php echo 'image-holder'.$topicid; ?>"></div>
</body>
</html>
Please let me know where to write slideToggle as to enable show/hide function properly. There are two links here which show separate images. They are shown when clicked but the problem is to hide them on next click and make them
visible when clicked again and so on.
The way you have your code here is not really quite right for .slideToggle. You should not put the URL for the image in the href attribute of an <a> element because the link will try to go there on click.
The way .slideToggle works is well documented on the docs page. All you have to do is use the HTML <img> tag, which is made to hold images. Then you $().hide(); them when the page loads so they aren't shown. All you have to do them is call the .slideToggle() function on the link click event.
See the working example with some misc pictures in this fiddle: http://jsfiddle.net/8xcZT/5/.
Or here is a working version of your code: http://jsfiddle.net/JMXba/9/. I can see this may be desirable to wait for the click to load the image.
Good Luck!
I'm reading up all I can on jQuery, but this week I like(need) to finish a website and I could find a solution to this problem in the last eight hours.
Setting
I'm using a ajaxed wp theme which I'm customising to my own liking.
Problem
I've wrote a simple function to change the header image and the header text when you click on the main navigation links.
The function does work in the header.php but doesn't work in a custom front page (main_navp.php) I've included in index.php.
On navp.php there's an image when onclicked should do the same changes as a click on the nav bar.
index.php
<?php get_header(); ?>
<div id="main-content"><div id="inside">
<?php get_template_part('main_navp'); ?>
<?php if// HERE IS THE WP LOOP (not used so left out) //?>
<div class="pagination">
<span class="older"><?php next_posts_link('« Older Entries') ?></span>
<span class="newer"><?php previous_posts_link('Newer Entries »') ?></span>
</div>``
<?php else : ?>
<h1>no posts...</h1>
<?php endif; ?>
</div></div>
<?php get_sidebar(); ?>
<?php get_footer(); ?>
The function is included in the header.php in the ..head>
<script type="text/javascript">
$(document).ready(function()
{
$("a[title='Gigs']").click(function()
{
$("#main_logo").css("background-image","url(<?php bloginfo('stylesheet_directory'); ?>/images/header/gig_header_flip.png)");
$("a#nav_text").html("Gigs");
});
$("a[title='Bio']").click(function()
{
$("#main_logo").css("background-image","url(<?php bloginfo('stylesheet_directory'); ?>/images/header/play_header.png)");
$("a#nav_text").html("Biography");
});
$("a[title='Gitaarles']").click(function()
{
$("#main_logo").css("background-image","url(<?php bloginfo('stylesheet_directory'); ?>/images/header/les_header.png)");
$("a#nav_text").html("Gitaarles");
});
$("p[id='les_mp']").live("click", function()
{
$("#main_logo").css("background-image","url(<?php bloginfo('stylesheet_directory'); ?>/images/header/les_header.png)");
$("a#nav_text").html("Gitaarles");
});
$("li[id='homew']").click(function()
{
$("#main_logo").css("background-image","url(<?php bloginfo('stylesheet_directory'); ?>/images/header/header_arty.png)");
$("a#nav_text").html("Home");
});
});
</script>
In the main_navp.php (included in index.php afther the header.php) the function does not work on this item. But it should be triggered by $("p[id='les_mp']").live("click", function() as seen above.
<div id="boxred_b">
<div class=head_box><a>Gitaarles</a></div>
<p class="homeles" id="les_mp">
<img src="<?php bloginfo('stylesheet_directory'); ?>/images/les_mp.jpg" />
</p>
The main jquery is caled in the header.php
<script src='<?php bloginfo('template_directory'); ?>/js/jjquery-1.5.2.min.js'></script>
In the footer.php are all of the rest of the jquery functions.

$.address.value(path);

$allLinks.removeClass("current_link");
$el.addClass("current_link").parent().addClass("current_page_item");
return false;
}
// Default action (go to link) prevented for comment-related links (which use onclick attributes)
e.preventDefault();
});
$('#searchform').submit(function() {
var s = $searchInput.val();
if (s) {
var query = '/?s=' + s;
$.address.value(query);
}
return false;
});
$.address.change(function(event) {
if (event.value) {
$ajaxSpinner.fadeIn();
$mainContent
.empty()
.load(base + event.value + ' #inside', function() {
$ajaxSpinner.fadeOut();
$mainContent.fadeIn();
});
}
var current = location.protocol + '//' + location.hostname + location.pathname;
if (base + '/' != current) {
var diff = current.replace(base);
location = base + '/#' + diff;
}
});
</script>
</div>
I've tried to keep things as short as possible. If you like any more information please ask.
-update
using the live function in the header doesn't seem to solve the problem.
I'm using XAMPP to run the website locally. If it helps I could make an online wp installation or could provide the webside (html/java) source.
Because you are Ajax-ing your page, the events are not subscribed to your new elements. Try using the .live() command.
Also, is this ok?
$("p[id='les_mp']").click(, function()...
Don't know for sure about that comma.
I've tried using the live function in the code like this.
$("p[id='les_mp']").live("click", function()
{
$("#main_logo").css("background-image","url(<?php bloginfo('stylesheet_directory'); ?>/images/header/les_header.png)");
$("a#nav_text").html("Gitaarles");
});
in the
$(document).ready(function()
{ .... }
in header.php
Still it doesn't work when be onclicked in main_nav.php
When I put the code out of the main_nav in to the header.php
it works.
You may want to use the method in the link below to refactor the ajax stuff to a separate file. Not sure if it helps with the original problem, but i've seen things work after doing that http://www.garyc40.com/2010/03/5-tips-for-using-ajax-in-wordpress/#js-global
basically you get your url into a variable that is being printed and your scripts have access to using wp_localize_script
