I have this little snippet of code that works great in JSFiddle and in a Chrome extension. On clicking "button" it blurs the ID "content".
var dimthis = $("#content")
var button = $("button")
button.on("click", () => {
dimthis.toggleClass("alt")
});
I've been through quite a few of the similar question that say to add $(document).ready(function(){
before and this });`
at the end giving this
$(document).ready(function(){
var dimthis = $("#content")
var button = $("button")
button.on("click", () => {
dimthis.toggleClass("alt")
});
});
That has worked for me before but not helping with this little ditty of code.
When I add the second set of code I get "$ is not a function error"
Thanks in advance for the help.
***** ANSWER (since I can't post answers for some reason) ******
This is a Wordpress site and Wordpress uses jQuery.noConflict();
So, in Wordpress, $ is undefined ergo the message "$ is not a function error"
Instead of
$(document).ready(function(){
in Wordpress you need to use
jQuery(document).ready(function($) {
What worked is putting it in the child-themes funtion.php like this:
function load_dimmer_script(){
?>
<script>
jQuery(document).ready(function($) {
var dimthis = $("#content")
var button = $("button")
button.on("click", () => {
dimthis.toggleClass("alt")
});
});
</script>
<?php
}
add_action( 'wp_footer', 'load_dimmer_script' );
What this does is this: If the menu toggle is defined as a button, when the menu is clicked the content of the page (#content) gets blurred. Click menu toggle again, it goes unblurred.
See nova-energy.net
Here's the one piece of CSS needed:
#content.alt {
filter: blur(4px) !important;
}
You have to wrap the JS code:
jQuery(document).ready(function($) {
// your code
)};
In wordpress, when using a theme, how can I prevent a click event from happening on a custom link. I am thinking of adding the following:
onClick="return false"
I am trying to prevent the page from scrolling down unexpectedly, when clicked.
do you have access to the theme edition? If so, you can try to use something like the code below, it's
add in footer.php
if you do not have access, but the theme has some custom field.
<script>
//JQUERY
(function ($) {
$('a[href=#]').click(function (e) {
e.preventDefault();
})
})(jQuery)
//JS PURE
document.querySelectorAll('a[href="#"]').forEach(function(ele, i){
ele.addEventListener('click', function (e) {
e.preventDefault();
})
})
</script>
I have a multi-page gravity form. I've echoed it using do_shortcode within the theme template.
I have content on the same page below the gravity form (which resides inside the wp editor (the_content() wrapped in a div with its own class) ).
Is there a way for me to hide this content on page 2 or later of the gravity form? I would still like it to appear on page 1 of the gf form.
Here was the final code that worked for me:
<script type="text/javascript">
jQuery(document).bind('gform_post_render', function(event, form_id, current_page){
jQuery('.page-content').toggle(current_page == 1);
});
</script>
I placed this in header.php
Lets say the class name of the div that is wrapping the_content() is "entry-content" and you want to hide it when the form is on second page. Add the following jQuery code to your theme and It will hide that div when someone goes to 2nd page. If they return back to 1st page of the form. It will show the content again.
<script type="text/javascript">// <![CDATA[
jQuery(document).bind('gform_page_loaded', function(event, form_id, current_page){
if(current_page == "1"){
jQuery('.entry-content').show();
} else {
jQuery('.entry-content').hide();
}
});
// ]]></script>
If you donot want to show the content even if they come back to page 1, then you can use the following code.
<script type="text/javascript">// <![CDATA[
jQuery(document).bind('gform_page_loaded', function(event, form_id, current_page){
jQuery('.entry-content').hide();
});
// ]]></script>

I am making my first, basic attempt to make a popup window JavaScript for a WordPress site. I'm using jQueryUI's dialog() function. My expected behavior is that a popup would appear when the page loads, but this is not happening. I am using the basic example from http://jqueryui.com/dialog/#default
I made a test html page with a div that the jQuery can grab:
<div id="dialog" title="Basic dialog">
<p>This is the default dialog which is useful for displaying information. The dialog window can be moved, resized and closed with the 'x' icon.</p>
</div>
My jQueryUI script code is just this:
jQuery(document).ready(function() {
$( "#dialog" ).dialog();
});
I've saved this script to a file popup.js.
I then enqueued the script using the following code, which works fine, as I can see the script in the HTML source of my web page:
function my_popup_script() {
wp_enqueue_script(
'my-popup-script',
get_stylesheet_directory_uri() . '/js/popup.js',
array( 'jquery' )
);
}
add_action( 'wp_enqueue_scripts', 'my_popup_script' );
I'm not sure where in this process I'm making an error. Thanks for your help.
it's only a jquery conflict, try this:
jQuery(document).ready(function() {
jQuery( "#dialog" ).dialog();
});
you can use the jquery noConflict function if you want to use the jquery object as a $ sign, just put this line before all the jquery code:
var $ = jQuery.noConflict();
If you want it to Popup on click event so you can use:
var $ = jQuery.noConflict();
$(document).ready(function() {
$('.the_button').click(function(){
$( "#dialog" ).dialog();
});
});
I know there is at least 1 other post on SO dealing with this but the answer was never exactly laid out.
I am working in a WP child theme in the head.php document. I have added this in the head:
<link type="text/css" href="http://www.frontporchdeals.com/wordpress/wp-includes/js/jqueryui/css/ui-lightness/jquery-ui-1.8.12.custom.css" rel="Stylesheet" />
<?php
wp_enqueue_style('template-style',get_bloginfo('stylesheet_url'),'',version_cache(),'screen');
wp_enqueue_script('jquery-template',get_bloginfo('template_directory').'/js/jquery.template.js',array('jquery'),version_cache(), true);
wp_enqueue_style('jquery-style', 'http://ajax.googleapis.com/ajax/libs/jqueryui/1.8.1/themes/smoothness/jquery-ui.css');
wp_enqueue_script('jq-ui', 'http://ajax.googleapis.com/ajax/libs/jqueryui/1.8.2/jquery-ui.js ');
wp_enqueue_script('jq-ui-min', 'http://ajax.googleapis.com/ajax/libs/jqueryui/1.8.12/jquery-ui.min.js' );
?>
and I added this in the body:
<script>
jQuery(function() {
$( "#dialog" ).dialog();
});
</script>
<div id="dialog" title="Basic dialog">
<p>This is the default dialog which is useful for displaying information. The dialog window can be moved, resized and closed with the 'x' icon.</p>
</div>
but no dice. My div shows as standard div.
Any ideas at all? I know that top stylesheet should be called with enqueue but that shouldn't stop this from working.
WordPress jQuery is called in no-conflict mode:
jQuery(document).ready(function($) {
$('#dialog' ).dialog();
});
Also jQuery UI is loading before jQuery. You're getting 2 javascript errors:
Uncaught ReferenceError: jQuery is not defined
103Uncaught TypeError: Property '$' of object [object DOMWindow] is not a function
The first error is from jQuery UI loading before jQuery and the second is because the $ is not recognized in no-conflict mode.
Remove any of the inline <script src= tags and the call to the custom.css in header php and add this function to your child theme functions.php file to load the scripts. WordPress will put them in the right order for you.
add_action( 'init', 'frontporch_enqueue_scripts' );
function frontporch_enqueue_scripts() {
if (!is_admin() ) {
wp_enqueue_script( 'jquery' );
wp_register_script( 'google-jquery-ui', 'http://ajax.googleapis.com/ajax/libs/jqueryui/1.8.12/jquery-ui.min.js', array( 'jquery' ) );
wp_register_script( 'jquery-template', get_bloginfo('template_directory').'/js/jquery.template.js',array('jquery'),version_cache(), true);
wp_register_style( 'jquery-style', 'http://ajax.googleapis.com/ajax/libs/jqueryui/1.8.1/themes/smoothness/jquery-ui.css', true);
wp_register_style( 'template-style', 'http://www.frontporchdeals.com/wordpress/wp-includes/js/jqueryui/css/ui-lightness/jquery-ui-1.8.12.custom.css', true);
wp_enqueue_style( 'jquery-style' );
wp_enqueue_style( ' jquery-template' );
wp_enqueue_script( 'google-jquery-ui' );
wp_enqueue_script( 'jquery-template' );
}
}
I'm building a custom plugin on WP admin to insert data on custom MySQL tables. For nearly a week I was trying to do a confirmation dialog for a delete item event on a Wordpress table. After I almost lost all my hair searching for an answer, it seemed too good and simple to be true. But worked. Follows the code.
EDIT: turns out that the wp standard jquery wasn't working properly, and the Google hosted jQuery included in another class was making the correct calls for the JS. When I removed the unregister/register added below, ALL the other dialog calls stopped working. I don't know why this happened, or the jQuery version included in this particular WP distribution, but when I returned to the old registrations, using Google hosted scripts as seen below, everything went back to normality.
On PHP (first, register and call the script):
add_action('admin_init', 'init_scripts_2');
function init_scripts_2(){
///deregister the WP included jQuery and style for the dialog and add the libs from Google
wp_deregister_script('jquery-ui');
wp_register_script('jquery-ui', 'http://ajax.googleapis.com/ajax/libs/jqueryui/1.10.2/jquery-ui.min.js');
wp_deregister_style('jquery-ui-pepper-grinder');
wp_register_style('jquery-ui-pepper-grinder', 'http://ajax.googleapis.com/ajax/libs/jqueryui/1.10.2/themes/pepper-grinder/jquery-ui.min.css');
wp_enqueue_script('jquery-ui'); ///call the recently added jquery
wp_enqueue_style('jquery-ui-pepper-grinder'); ///call the recently added style
wp_deregister_script('prevent_delete'); ///needed the deregister. why? don't know, but worked
///register again, localize and enqueue your script
wp_register_script('prevent_delete', WP_PLUGIN_URL . '/custom_plugin/js/prevent_delete.js', array('jquery-ui'));
wp_localize_script('prevent_delete', 'ajaxdelete', array('ajaxurl' => admin_url('admin-ajax.php')));
wp_enqueue_script('prevent_delete');
}
Next, if you're opening the dialog on a click event, like me, make sure you ALWAYS use class instead of id to identify the button or link later, on jQuery.
<a class="delete" href="?page=your_plugin&action=delete">Delete</a>
We also need to use a tag that holds the dialog text. I needed to set the style to hide the div.
<div id="dialog_id" style="display: none;">
Are you sure about this?
</div>
Finally, the jQuery.
/*jslint browser: true*/
/*global $, jQuery, alert*/
jQuery(document).ready(function ($) {
"use strict";
///on class click
$(".delete").click(function (e) {
e.preventDefault(); ///first, prevent the action
var targetUrl = $(this).attr("href"); ///the original delete call
///construct the dialog
$("#dialog_id").dialog({
autoOpen: false,
title: 'Confirmation',
modal: true,
buttons: {
"OK" : function () {
///if the user confirms, proceed with the original action
window.location.href = targetUrl;
},
"Cancel" : function () {
///otherwise, just close the dialog; the delete event was already interrupted
$(this).dialog("close");
}
}
});
///open the dialog window
$("#dialog_id").dialog("open");
});
});
EDIT: The call for the standard wp dialog style didn't work after all. The "pepper-grinder" style made the dialog appear correctly in the center of the window. I know the looks for the dialog are not very easy on the eye, but i needed the confirmation dialog and this worked just fine for me.
The dialog div is created AFTER when you're trying to act upon it. Instead, you should use:
$(document).ready(function() {
$( "#dialog" ).dialog();
});
