I created a small JQuery Plugin and I'm using thickbox for popups.
I don't know where it came from but I have a "0" appended to the end of the body element.
I suspect that one of those outputs a success indicator maybe?
Is anyone familiar with this behavior?
Edit:
PHP
add_action('wp_ajax_product_picker', 'popup_content');
function popup_content() {
iframe_header();
echo 'aaa';
iframe_footer();
}
JS
var currentPicker = {};
(function ($) {
$.fn.pick_product = function (options) {
var settings = $.extend({
callback: function(){}
}, options);
this.on('click',function () {
var url = product_picker.ajax_url + "?action=product_picker&TB_iframe=true&width=600&height=550";
tb_show("My Caption", url);
});
return this;
};
}(jQuery));
jQuery(function ($) {
$('#test-product-picker').pick_product({
callback: function (variation_id, size) {
alert('aaa');
}
});
});
If you are using it on the front end of your site you have to use the
wp_ajax_nopriv_product_picker and also place die() after your function.
function popup_content() {
iframe_header();
echo 'aaa';
iframe_footer();
die();
}

I have two function print and callPrint bellow. I click call function print the first time is right.
But when click call function print the second or third then function callPrint will be call 2 times or 3 times.
I have debug on attack file.
function print(url) {
console.log('print');
var _this = this, iframeId = 'iframeprint', $iframe = $('iframe#iframeprint');
if ($iframe.attr('src') != url) {
$.when(
$iframe.attr('src', 'about:blank'),
$iframe.load(function () {
console.log($iframe.prop('contentWindow').document.readyState);
})
).done(function () {
$iframe.attr('src', url);
$iframe.load(function () {
console.log('new');
_this.callPrint(iframeId);
});
});
} else {
console.log('old');
_this.callPrint(iframeId);
}
}
// initiates print once content has been loaded into iframe
function callPrint(iframeId) {
console.log('callPrint');
$('div.wait').hide();
var PDF = document.getElementById(iframeId);
PDF.focus();
PDF.contentWindow.print();
return false;
}
A JavaScript function is repeated many times
The problem is because you're attaching two new load() event handlers to the iframe every time print() is called. To fix this, add a single load() event handler and call your function from in there. This will be triggered whenever you update the src attribute on the element. Try this:
var $iframe = $('#iframeprint').load(function() {
// You'll need to make sure the function is in scope of the handler
// There's not enough information in the OP for me to show you how
callPrint('iframeprint');
});
function print(url) {
var _this = this;
if ($iframe.attr('src') != url) {
$iframe.attr('src', url);
} else {
_this.callPrint(iframeId);
}
}
Thanks "Rory McCrossan". I add setTimeout function when callPrint so dialog print will open. But I can't vote for you at the moment.
var $iframe = $('iframe#iframeprint').load(function () {
// You'll need to make sure the function is in scope of the handler
// There's not enough information in the OP for me to show you how
setTimeout(function () {
callPrint('iframeprint');
}, 100);
});
function print(url) {
if ($iframe.attr('src') != url) {
$iframe.attr('src', url);
} else {
console.log('old');
callPrint('iframeprint');
}
}
// initiates print once content has been loaded into iframe
function callPrint(iframeId) {
$('div.wait').hide();
var PDF = document.getElementById(iframeId);
PDF.focus();
PDF.contentWindow.print();
}
Hi I'm using JQUERY Dialog for a confirmation popup. I have a common javascript file, in which i had a function which used to call window.ShowModalDialog. Now from the same function i am calling the jquery dialog, but as it is an asynchronous call, the calling function returns the value(yes/no) without even accepting Values from dialog. How can i return the proper value(yes/no)
If I have correctly understood the problem ...
and if something is wrong, add the example of your code
Try using this pattern:
(function ($, undefined) {
$.fn.dialog = function (options) {
options = $.extend({}, $.fn.dialog.options, options);
return this.each(function () {
var dialog = $(this);
dialog.children(".ok").click(function (e) {
options.ok.call(this, e);
dialog.close();
});
dialog.children(".close").click(function (e) {
options.close.call(this, e);
dialog.close();
});
});
};
$.fn.open = function () {
this.get(0).showModal();
};
$.fn.close = function () {
this.get(0).close();
};
$.fn.dialog.options = {
ok : function () {},
close : function () {}
};
})(jQuery);
and using callback
var dialog = $(".myDialog").dialog({
ok : function () {
alert("ok!!");
}
});
Do everything you need in callback, but avoid callbackhell.
see example
I've got a file which needs to run on page load (randomise_colors.js), but also needs to be called by another file as part of a callback function (in infinite_scroll.js). The randomise_colors script just loops through a list of posts on the page and assigns each one a color from an array which is used on the front-end.
Infinite Scroll loads new posts in to the DOM on a button click, but because the randomise_colors.js file has already ran on page load, new content loaded is not affected by this so I need it to run again. I'm open to other suggestions if it sounds like I could be tackling the problem in a different way, I'm no JS expert.
Currently I'm getting Uncaught ReferenceError: randomise_colours is not defined referring this line of infinite_scroll.js:
randomise_colours.init();
I'm calling all files that need be loaded on document.ready in app.js
require(['base/randomise-colours', 'base/infinite-scroll'],
function(randomise_colours, infinite_scroll) {
var $ = jQuery;
$(document).ready(function() {
infinite_scroll.init();
randomise_colours.init();
});
}
);
This is infinite_scroll.js which initialises Infinite Scroll and features the callback. The callback function runs whenever new items are loaded in via AJAX using the Infinite Scroll jQuery plugin. I've put asterix around the area where I need to run the randomise_colors.init() function from randomise_colors.js.
define(['infinitescroll'], function() {
var $ = jQuery,
$loadMore = $('.load-more-posts a');
function addClasses() {
**randomise_colours.init();**
};
return {
init: function() {
if($loadMore.length >= 1) {
this.setUp();
} else {
return false;
}
},
setUp: function() {
this.initInfiniteScroll();
},
initInfiniteScroll: function() {
$('.article-listing').infinitescroll({
navSelector : '.load-more-posts',
nextSelector : '.load-more-posts a',
itemSelector : '.standard-post'
}, function(newItems) {
addClasses();
});
//Unbind the standard scroll-load function
$(window).unbind('.infscr');
//Click handler to retrieve new posts
$loadMore.on('click', function() {
$('.article-listing').infinitescroll('retrieve');
return false;
});
}
};
});
And this is my randomise_colors.js file which runs fine on load, but needs to be re-called again after new content has loaded in.
define([], function() {
var $ = jQuery,
$colouredSlide = $('.image-overlay'),
colours = ['#e4cba3', '#867d75', '#e1ecb9', '#f5f08a'],
used = [];
function pickRandomColour() {
if(colours.length == 0) {
colours.push.apply(colours, used);
used = [];
}
var selected = colours[Math.floor(Math.random() * colours.length)];
var getSelectedIndex = colours.indexOf(selected);
colours.splice(getSelectedIndex, 1);
used.push(selected);
return selected;
};
return {
init: function() {
if($colouredSlide.length >= 1) {
this.setUp();
} else {
return false;
}
},
setUp: function() {
this.randomiseColours();
},
randomiseColours: function() {
console.log('randomise');
$colouredSlide.each(function() {
var newColour = pickRandomColour();
$(this).css('background', newColour);
});
}
};
});
You would have to reference randomiseColours inside the infiniteScroll file. So you need to change your define function to the following:
define(['infinitescroll', 'randomise-colours'], function(infiniteScroll, randomise_colours)
Remember that when using require you need to reference all variables through the define function, otherwise they will not be recognised.
I've added a javascript element I found in a guide. It is as follows
$(document).ready(function ()
{
$('.dropdownbutton').click(function ()
{
$.post("send.php", $(".mycontactform").serialize(), function (data)
{
});
$('#success').html('Message sent!');
$('#success').hide(2000);
});
});
The existing javascript was
function toggleDisplayWait(divId, imgId, durationmSec) {
if(!$(divId).visible()) {
move = Effect.BlindDown;
newImage = "./img/minus.png";
}
else {
move = Effect.BlindUp;
newImage = "./img/plus.png";
}
move(divId, {duration: durationmSec / 1000.0 });
setTimeout(function() { $(imgId).src = newImage; }, durationmSec)
}
function BDEffect(divId, imgId)
{
/* new Effect.BlindDown(element, {duration:3});
}*/
if(!$(divId).visible())
{
move = Effect.BlindDown;
newImage = "./img/feedbacktab_open.png";
setTimeout(function() { $(imgId).src = newImage; }, 0)
}
else
{
move = Effect.BlindUp;
newImage = "./img/feedbacktab.png";
setTimeout(function() { $(imgId).src = newImage; }, 2)
}
move(divId, {duration:2});
/*setTimeout(function() { $(imgId).src = newImage; }, 0)*/
}
</script>
But neither the OLD code nor the NEW code works now.
Error console now reporting "$(divId).visible is not a function" when i try to use the old script
The old code looks like it's using the Prototype framework, and the new code is using jQuery.
When you use the two together, you need to use jQuery's noConflict() so that they don't both try to use the $ variable.
First, after including the jQuery library, add a script like this:
<script>
jQuery.noConflict()
</script>
Then modify your jQuery code to look like this:
jQuery(function ($) {
$('.dropdownbutton').click(function() {
$.post("send.php", $(".mycontactform").serialize(), function(data) {});
$('#success').html('Message sent!');
$('#success').hide(2000);
});
With noConflict, everywhere you want to use jQuery, you must use the jQuery variable instead of $. However, you can still pass $ in as a local variable, and it will not conflict with Prototype.
Also, note that I changed your document.ready(function() { ... }) function into jQuery's shorthand version: jQuery(function() { ... }). The function will also get passed the jQuery object, which I name $ for convenience.
I'm trying to build a Javascript listener for a small page that uses AJAX to load content based on the anchor in the URL. Looking online, I found and modified a script that uses setInterval() to do this and so far it works fine. However, I have other jQuery elements in the $(document).ready() for special effects for the menus and content. If I use setInterval() no other jQuery effects work. I finagled a way to get it work by including the jQuery effects in the loop for setInterval() like so:
$(document).ready(function() {
var pageScripts = function() {
pageEffects();
pageURL();
}
window.setInterval(pageScripts, 500);
});
var currentAnchor = null;
function pageEffects() {
// Popup Menus
$(".bannerMenu").hover(function() {
$(this).find("ul.bannerSubmenu").slideDown(300).show;
}, function() {
$(this).find("ul.bannerSubmenu").slideUp(400);
});
$(".panel").hover(function() {
$(this).find(".panelContent").fadeIn(200);
}, function() {
$(this).find(".panelContent").fadeOut(300);
});
// REL Links Control
$("a[rel='_blank']").click(function() {
this.target = "_blank";
});
$("a[rel='share']").click(function(event) {
var share_url = $(this).attr("href");
window.open(share_url, "Share", "width=768, height=450");
event.preventDefault();
});
}
function pageURL() {
if (currentAnchor != document.location.hash) {
currentAnchor = document.location.hash;
if (!currentAnchor) {
query = "section=home";
} else {
var splits = currentAnchor.substring(1).split("&");
var section = splits[0];
delete splits[0];
var params = splits.join("&");
var query = "section=" + section + params;
}
$.get("loader.php", query, function(data) {
$("#load").fadeIn("fast");
$("#content").fadeOut(100).html(data).fadeIn(500);
$("#load").fadeOut("fast");
});
}
}
This works fine for a while but after a few minutes of the page being loaded, it drags to a near stop in IE and Firefox. I checked the FF Error Console and it comes back with an error "Too many Recursions." Chrome seems to not care and the page continues to run more or less normally despite the amount of time it's been open.
It would seem to me that the pageEffects() call is causing the issue with the recursion, however, any attempts to move it out of the loop breaks them and they cease to work as soon as setInterval makes it first loop.
Any help on this would be greatly appreciated!
I am guessing that the pageEffects need added to the pageURL content.
At the very least this should be more efficient and prevent duplicate handlers
$(document).ready(function() {
pageEffects($('body'));
(function(){
pageURL();
window.setTimeout(arguments.callee, 500);
})();
});
var currentAnchor = null;
function pageEffects(parent) {
// Popup Menus
parent.find(".bannerMenu").each(function() {
$(this).unbind('mouseenter mouseleave');
var proxy = {
subMenu: $(this).find("ul.bannerSubmenu"),
handlerIn: function() {
this.subMenu.slideDown(300).show();
},
handlerOut: function() {
this.subMenu.slideUp(400).hide();
}
};
$(this).hover(proxy.handlerIn, proxy.handlerOut);
});
parent.find(".panel").each(function() {
$(this).unbind('mouseenter mouseleave');
var proxy = {
content: panel.find(".panelContent"),
handlerIn: function() {
this.content.fadeIn(200).show();
},
handlerOut: function() {
this.content.slideUp(400).hide();
}
};
$(this).hover(proxy.handlerIn, proxy.handlerOut);
});
// REL Links Control
parent.find("a[rel='_blank']").each(function() {
$(this).target = "_blank";
});
parent.find("a[rel='share']").click(function(event) {
var share_url = $(this).attr("href");
window.open(share_url, "Share", "width=768, height=450");
event.preventDefault();
});
}
function pageURL() {
if (currentAnchor != document.location.hash) {
currentAnchor = document.location.hash;
if (!currentAnchor) {
query = "section=home";
} else {
var splits = currentAnchor.substring(1).split("&");
var section = splits[0];
delete splits[0];
var params = splits.join("&");
var query = "section=" + section + params;
}
var content = $("#content");
$.get("loader.php", query, function(data) {
$("#load").fadeIn("fast");
content.fadeOut(100).html(data).fadeIn(500);
$("#load").fadeOut("fast");
});
pageEffects(content);
}
}
Thanks for the suggestions. I tried a few of them and they still did not lead to the desirable effects. After some cautious testing, I found out what was happening. With jQuery (and presumably Javascript as a whole), whenever an AJAX callback is made, the elements brought in through the callback are not binded to what was originally binded in the document, they must be rebinded. You can either do this by recalling all the jQuery events on a successful callback or by using the .live() event in jQuery's library. I opted for .live() and it works like a charm now and no more recursive errors :D.
$(document).ready(function() {
// Popup Menus
$(".bannerMenu").live("hover", function(event) {
if (event.type == "mouseover") {
$(this).find("ul.bannerSubmenu").slideDown(300);
} else {
$(this).find("ul.bannerSubmenu").slideUp(400);
}
});
// Rollover Content
$(".panel").live("hover", function(event) {
if (event.type == "mouseover") {
$(this).find(".panelContent").fadeIn(200);
} else {
$(this).find(".panelContent").fadeOut(300);
}
});
// HREF Events
$("a[rel='_blank']").live("click", function(event) {
var target = $(this).attr("href");
window.open(target, "_blank");
event.preventDefault();
});
$("a[rel='share']").live("click", function(event) {
var share_url = $(this).attr("href");
window.open(share_url, "Share", "width=768, height=450");
event.preventDefault();
});
setInterval("checkAnchor()", 500);
});
var currentAnchor = null;
function checkAnchor() {
if (currentAnchor != document.location.hash) {
currentAnchor = document.location.hash;
if (!currentAnchor) {
query = "section=home";
} else {
var splits = currentAnchor.substring(1).split("&");
var section = splits[0];
delete splits[0];
var params = splits.join("&");
var query = "section=" + section + params;
}
$.get("loader.php", query, function(data) {
$("#load").fadeIn(200);
$("#content").fadeOut(200).html(data).fadeIn(200);
$("#load").fadeOut(200);
});
}
}
Anywho, the page works as intended even in IE (which I rarely check for compatibility). Hopefully, some other newb will learn from my mistakes :p.
