Ive been struggling with this for hours now. I can't figure out why my .load() callback is not firing. Can anyone shed any light on this. Thanks for any help.
The load it's self works fine.
window.addEventListener('popstate', function(event) {
var linkplus = ((event.state) + ' #container'); //contents
if((event.state)==null){
$("#maincontainer").load("index.php #container", "null" , function(){
return false;
// why is this not working ??? //
alert("contents loaded");
});
}else{
$("#maincontainer").load(linkplus, function(){
return false;
$("#container").hide().delay(0).fadeIn(400);
project_nav();
});
}
});
hm, doesn't look like your alert would be hit right? You already return false before that.
When you return from a function, you return
$("#maincontainer").load("index.php #container", "null" , function(){
return false; // YOU RETURNED HERE, NOTHING BELOW IS EXECUTED
alert("contents loaded");
});
There's no need to return anything from load()
Hey I tried removing the "return false" with no success.I think it's because .load() is asynchronous?
Anyway, I got it to work using ".get" instead of .load and then selecting the contents with a variable. Thanks for the replies.
$.get( "index.php", function( data ) {
var content = $(data).find('#container').html();
$("#container").html(content);
alert("contents loaded");
});

My code is like this:
$('.flag-icon-dz').click(function() {
var lang = 'Arab';
var $frame = $('.goog-te-menu-frame:first');
if (!$frame.size()) {
console.log("Error: Could not find Google translate frame.");
return false;
}
$frame.contents().find('.goog-te-menu2-item span.text:contains(' + lang + ')').get(0).click();
$("li.ql-item.linkid188546").after("<li class='ql-item linkid18854777 closegoogle'><a href='#' class='btn-primary' target='_self'><i class='icon closegoogle ls-lang-frr' aria-hidden='true'></i></a></li>").fadeIn(500);
$('li.ql-item.linkid188546').fadeOut(500);
return false;
});
$('.closegoogle').click(function() {
$('.skiptranslate').contents().find('.goog-close-link > img').click();
$('li.ql-item.linkid18854777').fadeOut('fast').remove();
$('li.ql-item.linkid188546').fadeIn(500);
});
The first function works great, but the second doesn't. I realize that if I copy/paste the second function in the console after the first one, it works too.
I tried a few solutions (callback / setTimeout / jquery deferred / jquery .when method...) I didn't try promise but I don't think I have to in my context. Maybe I didn't write these solutions good enough.
I finally try to put my event (click) directly the .before() which create my new element like this :
$('.flag-icon-dz').click(function() {
var lang = 'Arab';
var $frame = $('.goog-te-menu-frame:first');
if (!$frame.size()) {
console.log("Error: Could not find Google translate frame.");
return false;
}
$frame.contents().find('.goog-te-menu2-item span.text:contains(' + lang + ')').get(0).click();
$("li.ql-item.linkid188546").after("<li class='ql-item linkid18854777 closegoogle'><a href='#' class='btn-primary' target='_self'><i class='icon closegoogle ls-lang-frr' aria-hidden='true'></i></a></li>").fadeIn(500).click(function() {
$('.skiptranslate').contents().find('.goog-close-link > img').click();
$('li.ql-item.linkid18854777').fadeOut('fast').remove();
$('li.ql-item.linkid188546').fadeIn(500);
});
$('li.ql-item.linkid188546').fadeOut(500);
return false;
});
But it doesn't work either.
Thanks for the help.
EDIT :
I finally found a kind of solution for my second click event (which isn't the best solution but i works) :
window.setInterval(function(){$('.closegoogle').on("click",function(){
$('.skiptranslate').contents().find('.goog-close-link > img').click();
$('li.ql-item.linkid18854777').fadeOut('fast').remove();
$('li.ql-item.linkid188546').fadeIn(500);
}); }, 1000);
Thanks.
You need to use a delegated bind as the element does not exist before you try your binding:
$('#parent-element-of-closegoogle').on('click', '.closegoogle', function() {
$('.skiptranslate').contents().find('.goog-close-link > img').click();
$('li.ql-item.linkid18854777').fadeOut('fast').remove();
$('li.ql-item.linkid188546').fadeIn(500);
});
Please note that the #parent-element-of-closegoogle needs to be an element that already exists when you do the binding - this can be $(document) if you hjave no other element to bind to
I am using codepress in a CMS to edit files in the filesystem. Everything works nicely, however when trying to load the same page using jQuery load() function, codepress seems to break.
My javascript code looks like this which loads the php file with codpress, however codepress seems to not fire.
$('.content').on('click', '#fileSystemWrap a', function (event) {
event.preventDefault();
var fileName = $(this).data('file');
$('#rightColWrap').fadeOut(150, function(){
$('#rightColWrap').load('/?url=developer/edit-file.php&open=' + fileName, function(){
$('#rightColWrap').fadeIn(150);
});
});
});
Digging into codepress.js I see this at the end of the file but I'm not understanding if there is something I could add to my initial on click event listner script to help codpress fire.
if(window.attachEvent) window.attachEvent('onload',CodePress.run);
else window.addEventListener('DOMContentLoaded',CodePress.run,false);
Here is the link to codepress on sourceforge
https://sourceforge.net/projects/codepress/
To be logic : when the data are loaded, we want to initialize CodePress.
So your code should look like :
$('.content').on('click', '#fileSystemWrap a', function (event) {
event.preventDefault();
var fileName = $(this).data('file');
$('#rightColWrap').fadeOut(150, function(){
$('#rightColWrap').load('/?url=developer/edit-file.php&open=' + fileName, function(){
CodePress.run();
$('#rightColWrap').fadeIn(150);
});
});
});
If this didn't work please provide error from the console.
Edit : corrected answer, seen Robson França's comment.
Last issue was that CodePress.run; should have been written CodePress.run();
The answer was that we needed to add parentheses to CodePress.run and after the fadeIn() call.
$('#content').on('click', '#fileSystemWrap a', function (event) {
event.preventDefault();
var fileName = $(this).data('file');
$('#content').fadeOut(150, function(){
$('#content').load('/?url=developer/edit-file.php&open=' + fileName, function(){
$('#content').fadeIn(150, function(){
CodePress.run();
});
});
});
});
I'm somewhat new to Javascript. I'm trying to make it so that clicking on an image on one page takes you to a new page and shows a specific div on that new page, so I used sessionStorage to remember and booleans to keep track of which image is being clicked. Right now, the code always executes the first if statement, regardless of which image is clicked. This code works fine in normal java so I can't figure out why my if statements are being ignored in javascript. I also tried adding an 'else' at the end, and tried ===. Here's my javscript, and thank you!
sessionStorage.clickedLeft;
sessionStorage.clickedMiddle;
sessionStorage.clickedRight;
function openedProjectFromGallery() {
if(sessionStorage.clickedLeft) {
$(".left-project-pop-up").show();
} else if (sessionStorage.clickedMiddle) {
$(".middle-project-pop-up").show();
} else if (sessionStorage.clickedRight) {
$(".right-project-pop-up").show();
}
sessionStorage.clickedLeft = false;
sessionStorage.clickedMiddle = false;
sessionStorage.clickedRight = false;
}
$("document").ready(function () {
$(".pop-up .x-button").click(function(){
$(".pop-up").hide();
});
$(".project-description .x-button").click(function(){
$(".project-pop-up").hide();
});
$(".left-project-thumb img").on("click", ".left-project-thumb img", function(){
sessionStorage.clickedLeft = true;
sessionStorage.clickedMiddle = false;
sessionStorage.clickedRight = false;
openedProjectFromGallery();
});
$(".profile-left-project img").click(function(){
$(".left-project-pop-up").show(1000);
});
$(".middle-project-thumb img").on("click", ".middle-project-thumb img", (function(){
sessionStorage.clickedMiddle = true;
sessionStorage.clickedLeft = false;
sessionStorage.clickedRight = false;
openedProjectFromGallery();
});
$(".profile-middle-project img").click(function(){
$(".middle-project-pop-up").show(1000);
});
$(".right-project-thumb img").on("click", ".right-project-thumb img", (function(){
sessionStorage.clickedRight = true;
sessionStorage.clickedLeft = false;
sessionStorage.clickedMiddle = false;
openedProjectFromGallery();
});
$(".profile-right-project img").click(function(){
$(".right-project-pop-up").show(1000);
});
});
You are defining function openedProjectFromGallery() with in document.ready . Define it outside document.ready and also give your three booleans some initial value at the top of your code if not initialized with some value or they are empty. I hope this would help.
It is not really answer to your orginal question,as the main issue with your code is, as #njzk2 says, that openProjectFromGallery only being called once, and not on each event, however I wanted to put my two coins on how this code could look like.
This is good example where custom events should be used
$(document).on('showPopup', function( e, popup ) {
$('.'+popup + '-project-pop-up').show()
})
$(document).on('hidePopup', function( e ) {
$('.popup').hide()
})
$('.left-project-thumb img').on('click', function(e) {
$(document).trigger('showPopup', ['left'])
})
$('.right-project-thumb img').on('click', function(e) {
$(document).trigger('showPopup', ['right'])
})
I think you get an idea.
On the other hand, it always nice to use event delegation with a lot of similar events as well as dom data.
<div class='popup' data-popup='left'>
<img />
</div>
$(document).on('click','.popup', function( e ) {
$(document).trigger('showPopup', [$(this).data('popup')])
})
From what I can see openedProjectFromGallery is only getting called on document load.
Add a call to it into each of the event handling functions or use jQuery's delegate function to assign event handling to each image.
I'm a javascript newbie and I'm trying to call a jQuery function in this way:
function getProducts(){
$.post("products.php",
{
customer_ID:$("#customers").val()
},
function(data,status){
return status && data !== "";
});
};
$(document).ready(function(){
$("#customers").change(function(){
if(getProducts){
alert("trovato");
$("#products").prop("disabled", false);
$("#products").html(data);
}else{
alert("non trovato");
$("#products").empty();
$("#products").prop("disabled", true);
}
});
});
The if-else statement in the ready doesn't work although the function getProducts works properly. The problem, I suppose, is in the function call. What am I wrong with this? Thank you.
You need to wrap the response with a callback, like so:
function getProducts(callback){
$.post("products.php",
{
customer_ID:$("#customers").val()
},
function(data,status){
callback(status && data !== "");
});
};
$(document).ready(function(){
$("#customers").change(function(){
getProducts(function(status) {
if(status){
alert("trovato");
$("#products").prop("disabled", false);
$("#products").html(data);
}else{
alert("non trovato");
$("#products").empty();
$("#products").prop("disabled", true);
}
});
});
});
I'm not quite sure if this will work because of the asynchronized call inside of the function.
The obvious mistake is that you have to call a function like that: function(). You just forgot the parentheses.
If it won't work after that fix, you have to rework your program to use callbacks where you have asynchron calls.
I'm trying to something like this if in the html there is a div called "#super" load it in the simple modal if not do nothing. I managed to do this with the my skill :D which is none: to load the modal if the #super exists, but it still loads doesn't matter if it exitst or not. PLease help I'm absolute noob on jquery.
if( $('super') ){ $("#super").modal({onOpen: function (dialog) {
dialog.overlay.fadeIn('slow', function () {
dialog.container.slideDown('slow', function () {
dialog.data.fadeIn('slow');
});
});
}});
I'm using this jquery plugin link text
If #super does not exist, nothing will happen. So, the following should fit your needs:
$("#super").modal({onOpen: function (dialog) {
dialog.overlay.fadeIn('slow', function () {
dialog.container.slideDown('slow', function () {
dialog.data.fadeIn('slow');
});
});
});
I'm not quite sure what it is that you want to do, in the if/else conditions, but to test for the existence of something:
if ($('#super').length) {
// it exists, do stuff
}
else {
// it doesn't exist, do other stuff. Or nothing
}
I'm sorry I can't be more specific, but I've not worked with the dialog/modal plugin.
The problem is this check
if( $('#super') )
will always return true, since the jQuery function always return a jQuery object which is not a false value.
Instead try this
if( $('#super').length > 0 )
