Having trouble with JS object literal setup - javascript

So I've setup my first JS design pattern - but I've run into an issue.
Here is my code on fiddle:
http://jsfiddle.net/jrutter/CtMNX/
var emailSignup = {
'config': {
// Configurable Options
'container': $('#email-signup'),
'emailButton': $('#email-submit'),
'emailInput': $('#email-input'),
'brontoDirectAddURL': 'URL',
'brontoListID': '0bbc03ec000000000000000000000003287b',
},
'init': function (config) {
// stays the same
// provide for custom configuration via init()
if (config && typeof (config) == 'object') {
$.extend(emailSignup.config, config);
}
// Create and/or cache some DOM elements
emailSignup.$container = $(emailSignup.config.container);
emailSignup.$button = $(emailSignup.config.emailButton);
emailSignup.$input = $(emailSignup.config.emailInput);
emailSignup.$brontoURL = emailSignup.config.brontoDirectAddURL;
emailSignup.$brontoList = emailSignup.config.brontoListID;
// Add email track to drop image pixel into for submission
emailSignup.$container.append('<div class="email-error"></div>');
emailSignup.$container.append('<div class="email-track"></div>');
// Call getEmaile
emailSignup.getEmail(emailSignup.$button, emailSignup.$input);
// make a note that the initialization is complete
emailSignup.initialized = true;
},
'getEmail': function ($button, $input) {
// click event
emailSignup.$button.click(function () {
// get the val
var $emailVal = $(emailSignup.$input).val();
// Call validateEmail
console.log($emailVal);
emailSignup.validateEmail($emailVal);
return false;
});
},
'validateEmail': function ($emailVal) {
var $emailRegEx = /^([\w-\.]+#([\w-]+\.)+[\w-]{2,4})?$/;
//console.log($emailVal);
if ($emailVal == '') {
$(".email-error").html('<p>You forgot to enter an email address.</p>');
} else if (!$emailRegEx.test($emailVal)) {
$(".email-error").html('<p>Please enter a valid email address.</p>');
} else {
$(".email-error").hide();
emailSignup.submitEmail($emailVal);
}
},
'submitEmail': function ($emailVal) {
$(".email-track").html('<img src=' + emailSignup.$brontoURL+'&email='+$emailVal+'&list1=' + emailSignup.$brontoList + '" width="0" height="0" border="0" alt=""/>');
},
};
Its a function to add a subscriber to an email list via bronto - it works perfectly when the script is included on the page and the init function is setup on the page too. But when I include the script in a shared header and try to fire the function from the document-ready, it doesnt seem to be working.
Also, if I try to pass in a 'container' - that also is breaking the script. Not sure what Im doing wrong? But if I pass in the URL - that does work!
$(function () {
emailSignup.init({
'brontoDirectAddURL':'URL','container':'#email-signup'
});
});
Any advice would be greatly appreciated!

Change the following code...
emailSignup.$container = emailSignup.config.container;
emailSignup.$button = emailSignup.config.emailButton;
emailSignup.$input = emailSignup.config.emailInput;
emailSignup.$brontoURL = emailSignup.config.brontoDirectAddURL;
emailSignup.$brontoList = emailSignup.config.brontoListID;
into the following...
// Create and/or cache some DOM elements
emailSignup.$container = $(emailSignup.config.container);
emailSignup.$button = $(emailSignup.config.emailButton);
emailSignup.$input = $(emailSignup.config.emailInput);
emailSignup.$brontoURL = $(emailSignup.config.brontoDirectAddURL);
emailSignup.$brontoList = $(emailSignup.config.brontoListID);
// Add email track to drop image pixel into for submission
emailSignup.$container.append('<div class="email-error"></div>');
emailSignup.$container.append('<div class="email-track"></div>');
You can not call append on a string. I've update your JSFiddle.

Your default config object contains jQuery collections. However, you are simply passing the string "#email-signup" as your container instead of $("#email-signup"). That's where the error is coming from. Your initial call should thusly be:
$(function () {
emailSignup.init({
'brontoDirectAddURL':'URL','container': $('#email-signup')
});
});
Note that as your initial module includes some jQuery calls, you will need to wrap the whole emailSignup mess into a $(document).ready() as well.
You may consider reconfiguring this whole thing as a jQuery plugin.

Check if JS plugin is loaded before executing code

I'd like some insight into a little problem I'm encountering with a custom JS plugin that I've made. It's reasonably simple, I'm using a plugin JS template to write out plugins, which I'll attach. I'm then initialising the plugin, and ideally need to figure out if there's a way I can check if the plugin JS file is loaded before doing anything:
plugin template
(function() {
this.MyPlugin = function() {
// default settings
const INBOUND_CONFIG = {
isEnabled: false
}
// Create options by extending defaults with the passed in arugments
if (arguments[0] && typeof arguments[0] === "object") {
this.options = extendDefaults(INBOUND_CONFIG, arguments[0]);
}
// custom public method
HoneycombInbound.prototype.getSettings = function() {
}
// Utility method to extend defaults with user options
function extendDefaults(source, properties) {
var property;
for (property in properties) {
if (properties.hasOwnProperty(property)) {
source[property] = properties[property];
}
}
return source;
}
}
}());
With the above, I'd initialise the plugin in HTML as follows:
<script src="./my-plugin.js"></script>
<script>
const plugin = new MyPlugin()
// this doesn't work if the script file isn't linked:
if (plugin) {
// do something
}
</script>
Unfortunately, a simple check of plugin doesn't actually work if the JS file isn't loaded for instance, I've even tried something like: if (new MyPlugin()) {} with little hope.
I essentially need a way of not throwing an error in the browser. Any solution I can use to check correctly if it's loaded before executing?
A solution that has worked for me is to work with the WebAPI postMessage
I've used to communicate with the client, that the plugin is ready.
So on the plugin you will need something like this:
window.postMessage("The plugin is ready to go" );
And on your client you will need to add a new listener that can catch the message:
window.addEventListener("message", myMessage, false);
const myMessage = (event) => {
if (event.data === "The plugin is ready to go")
// This is your message so do your stuff here
...
}
EDIT
So to achieve this behavio, you will need to enable on the client sidethe initialization:
const myPlugin = {
init: () => {
// Initilize the plugin if you are using the DOM you can add a parameter with an id to mount it whenever you need it
//Otherwise just configure or initilize the variables that you will use
// And here you need to pass the messsage to tell the client that everyting is ready
// Here you need to configure the origin correctly depending on your needs check the documentation for more details
window.addEventListener("message", myMessage, false);
},
someFunctionality: () => {
//This pattern is to expose the funtionalities to the client so you can achieve any
}
};
So now on your client you just need to add your script and tell the plugin to initialize:
<script type='text/javascript' src='/myPlugin.js'></script>
<script>
window.addEventListener("message", myMessage, false);
const myMessage = (event) => {
if (event.data === "The plugin is ready to go")
// This is your message so do your stuff here
...
}
myPlugin.init();
</script>

infinite scroll on squarespace get category filter

I am using this code to infinite load a page on squarespace. My problem is the reloading doesn't capture the filtering that I have set up in my url. It cannot seem to 'see' the variables or even the url or categoryFilter in my collection. I've tried to use a .var directive but the lazy loaded items cannot see the scope of things defined before it. I'm running out of ideas here please help!
edit: I've since found the answer but gained another question.
I was able to use window.location.href instead of window.location.pathname to eventually get the parameters that way. Except this doesn't work in IE11 so now I have to search for this.
<script>
function infiniteScroll(parent, post) {
// Set some variables. We'll use all these later.
var postIndex = 1,
execute = true,
stuffBottom = Y.one(parent).get('clientHeight') + Y.one(parent).getY(),
urlQuery = window.location.pathname,
postNumber = Static.SQUARESPACE_CONTEXT.collection.itemCount,
presentNumber = Y.all(post).size();
Y.on('scroll', function() {
if (presentNumber >= postNumber && execute === true) {
Y.one(parent).append('<h1>There are no more posts.</h1>')
execute = false;
} else {
// A few more variables.
var spaceHeight = document.documentElement.clientHeight + window.scrollY,
next = false;
/*
This if statement measures if the distance from
the top of the page to the bottom of the content
is less than the scrollY position. If it is,
it's sets next to true.
*/
if (stuffBottom < spaceHeight && execute === true) {
next = true;
}
if (next === true) {
/*
Immediately set execute back to false.
This prevents the scroll listener from
firing too often.
*/
execute = false;
// Increment the post index.
postIndex++;
// Make the Ajax request.
Y.io(urlQuery + '?page=' + postIndex, {
on: {
success: function (x, o) {
try {
d = Y.DOM.create(o.responseText);
} catch (e) {
console.log("JSON Parse failed!");
return;
}
// Append the contents of the next page to this page.
Y.one(parent).append(Y.Selector.query(parent, d, true).innerHTML);
// Reset some variables.
stuffBottom = Y.one(parent).get('clientHeight') + Y.one(parent).getY();
presentNumber = Y.all(post).size();
execute = true;
}
}
});
}
}
});
}
// Call the function on domready.
Y.use('node', function() {
Y.on('domready', function() {
infiniteScroll('#content','.lazy-post');
});
});
</script>
I was able to get this script working the way I wanted.
I thought I could use:
Static.SQUARESPACE_CONTEXT.collection.itemCount
to get {collection.categoryFilter} like with jsont, like this:
Static.SQUARESPACE_CONTEXT.collection.categoryFilter
or this:
Static.SQUARESPACE_CONTEXT.categoryFilter
It didn't work so I instead changed
urlQuery = window.location.pathname
to
urlQuery = window.location.href
which gave me the parameters I needed.
The IE11 problem I encountered was this script uses
window.scrollY
I changed it to the ie11 compatible
Window.pageYOffset
and we were good to go!

Comparing strings using jQuery load function

Writing the code i am stuck with one thing. I am loading variable string through jQuery load function and there is where trouble starts. I want my code to check if string loaded through text file had any changes and if that is true make some actions. How do I set my variable as a string to compare it with the one in file? Part of the code
var follow, donate;
var auto_refresh = setInterval(function() {
follow = $('#followerid').load("../Muxy/most_recent_follower.txt");
donate = $('#donatorid').load("../Muxy/most_recent_donator.txt");
}, 100);
and then I want to make something like this:
someUpdateFunction() {
if($(#'followerid').get("innerHTML") != follow)
// actions (animations, div changes etc.)
}
That is probably totally wrong but I wasnt able to find any tips here. Thanks in advance
Try something like this:
$.get('../Muxy/most_recent_follower.txt', function (data) {
var followerid = $('#followerid').html();
if( followerid == data ){
// They are the same
}else{
// They are not the same
}
});
The .html() method will get the HTML inside #followerid. It sounds like that's what you want.
The jQuery.load function doesn't return the loaded file, it returns the element. Try out this:
var auto_refresh = setInterval(function() {
oldFollow = $('#followerid').html();
$('#followerid').load("../Muxy/most_recent_follower.txt");
oldDonate = $('#donatorid').html();
$('#donatorid').load("../Muxy/most_recent_donator.txt");
}, 100);
someUpdateFunction() {
if($('#followerid').html() !== oldFollow)
// actions (animations, div changes etc.)
}
}

This is the code for showing an error message "Error Loading Page" for error in page. Here i want to show alert message for net connection failure as "Please check your net connection" instead of the below image.
Note: I dont want to change the pageloaderrormessage. want to stop to get the page error messages, instead of that i will enable my network error condition as in Show Network Error in android. If the user pressed "Ok" in alert dialog i'll navigate them into Reload.html.
Please tell me where i can check that condition and where i have to change the error message?
As both #shkschneider and #codemonkey have suggested you need to set this option on mobileinit
Example:
$(document).bind("mobileinit", function(){
$.mobile.pageLoadErrorMessage = "Please check your net connection";
});
Linking the jQM 1.0.1 docs:
http://jquerymobile.com/demos/1.0.1/docs/api/globalconfig.html
Here is a example:
http://jquerymobile.com/demos/1.0.1/docs/config/pageLoadErrorMessage.html ( click the "or Try this broken link" button )
Now if you have the ability to upgrade jQM to 1.1.1 you might try something like this:
//use theme swatch "b", a custom message, and no spinner
$.mobile.showPageLoadingMsg("b", "Please check your net connection", true);
// hide after delay
setTimeout( $.mobile.hidePageLoadingMsg, 1500 );
Docs:
http://jquerymobile.com/demos/1.1.1/docs/api/methods.html
UPDATE:
Another thought is to use a plugin to achieve something like you want, Does something like this work?
http://dev.jtsage.com/jQM-SimpleDialog/demos/bool.html
Simply use:
$(document).bind("mobileinit", function(){
$.mobile.pageLoadErrorMessage("Please check your netconnection");
});
http://jquerymobile.com/test/docs/api/globalconfig.html
Set the pageLoadErrorMessage as described here http://jquerymobile.com/demos/1.1.1/docs/api/globalconfig.html
EDIT
If you want to handle the behaviour in a custom way, set loadingMessage to false. This prevents the loading message from being displayed. You can bind to the pageloadfailed (described here http://jquerymobile.com/demos/1.1.1/docs/api/events.html) and add add your custom handling logic in the event handler.

TinyMCE - Adding a Key Binding CNRTL-S COMMAND-S to call an AJAX save Function

I'd like to learn how to bind a CNRTL-S or COMMAND-S to call a function that I have on my page which AJAX saves the textarea content's
How can I bind those two commands? I used to use the following when it was just a textarea, but since adding TinyMCE it no longer works. Suggestions?
// Keybind the Control-Save
jQuery('#text_area_content').bind('keydown', 'ctrl+s',function (evt){
saveTextArea();
return false;
});
// Keybind the Meta-Save Mac
jQuery('#text_area_content').bind('keydown', 'meta+s',function (evt){
saveTextArea();
return false;
});
Thanks
To use a custom method for saving, i declare my saving function in the tinymce.init method
tinyMCE.init({
// General options
mode: "none",
/* some standard init params, plugins, ui, custom styles, etc */
save_onsavecallback: saveActiveEditor,
save_oncancelcallback: cancelActiveEditor
});
Then i define the function itself
function saveActiveEditor() {
var activeEditor = tinyMCE.activeEditor;
var saveUrl = "http://my.ajax.path/saveStuff";
var idEditor = activeEditor.id;
var contentEditor = activeEditor.getContent();
/* the next line is for a custom language listbox to edit different locales */
var localeEditor = activeEditor.controlManager.get('lbLanguages').selectedValue;
$.post(saveUrl ,
{ id: idEditor, content: contentEditor, locale: localeEditor },
function(results) {
if (results.Success) {
// switch back to display instead of edit
return false;
}
else {
activeEditor.windowManager.alert('Error saving data');
return false;
}
},
'json'
);
return false;
}
Don't forget to return false to override the default save action that posts back your data to the server.
edit to add: i only let the user change one tinymce instance at a time. You may want to change the locating the current instance to something else :)
edit #2: TinyMce already catches the Ctrl+s binding to process the data. Since it also cleans up html and is able to handle specific rules it's given when saving, the solution i propose is to plug your way of saving in tinyMce instead of fully overriding the Ctrl+s binding
The problem here is that the tinymce iframe does not delegate the events to the parent window. You can define custom_shortcuts in tinymce and/or use the following syntax:
// to delegate it to the parent window i use
var create_keydown_event = function(combo){
var e = { type : 'keydown' }, m = combo.split(/\+/);
for (var i=0, l=m.length; i<l; i++){
switch(m[i]){
case 'ctrl': e.metaKey = true;
case 'alt': case 'shift': e[m[i] + 'Key'] = true; break;
default : e.charCode = e.keyCode = e.which = m[i].toUpperCase().charCodeAt(0);
}
}
return e;
}
var handler = function(){
setTimeout(function(){
var e = create_keydown_event(combo);
window.parent.receiveShortCutEvent(e);
}, 1);
}
//ed.addShortcut(combo, description, handler);
ed.addShortcut('ctrl+s', 'save_shortcut', handler);
in the parent window you need a function receiveShortCutEvent which will sort out what to do with it
