Cannot communicate between captivate html and parent html

I have a published captivate html file that is loaded into an iframe of another html. I cannot communicate between the two, not even with localStorage. Can anyone tell me what I'm missing?
Parent html
var everythingLoaded = setInterval(function () {
if (/loaded|complete/.test(document.readyState)) {
clearInterval(everythingLoaded);
init();
}
}, 10);
function init() {
ScormProcessInitialize();
var studentID = ScormProcessGetValue("cmi.core.student_id");
var student_name = ScormProcessGetValue ("cmi.core.student_name");
var nameArraya = student_name.split(" ");
var nameArrayb = nameArraya[1].split(",");
var studentNumber = nameArrayb[0];
ScormProcessSetValue("cmi.core.lesson_status", "incomplete");
localStorage.setItem("_studentNumber", studentNumber);
alert("Student Number: " + studentNumber + " Student Mame: " + student_name);
setTimeout(function () {
document.getElementById("iFrame_a").innerHTML = "<iframe name='iframe_1' id='frame_1' src='//somepath.com/sandbox/somecourse/index.html' frameborder='0' width='1000px' height='605px'></iframe>";
}, 250);
}
function sendComplete() {
alert("Send from index start!");
ScormProcessSetValue("cmi.core.lesson_status", "completed");
alert("send status: Completed");
}
window.onbeforeunload = function (){
cpInfoCurrentSlide = localStorage.getItem("_cpInfoCurrentSlide")
alert(cpInfoCurrentSlide);
if(cpInfoCurrentSlide >= 40)
{
alert("onbeforeunload called: " + cpInfoCurrentSlide )
ScormProcessSetValue("cmi.core.lesson_status", "completed");
}
}
iframe code snippet
localStorage.setItem("_cpInfoCurrentSlide", cpInfoCurrentSlide);

I believe your problem is with onbeforeunload. As I remember captivate packages clobber any functions associated with onbeforeunload in the parent frame when they load.
Try this instead, override your SCORM api setvalue method:
var oldLMSSetValue = window.API.LMSSetValue;
window.API.LMSSetValue = function(key, value){
if(key === 'cmi.core.lesson_status' && value === 'completed'){
//do your stuff here
cpInfoCurrentSlide = localStorage.getItem("_cpInfoCurrentSlide")
alert(cpInfoCurrentSlide);
}
//call the original scorm api function so that it runs as expected.
oldLMSSetValue(key,value);
};
edit: this code would go in the parent window, not the iframe.

How do I fire a function immediately after another function is finished?

I have the following code:
<script>
function refreshChat() {
var id = "'.$convers_id.'";
var receiver = "'.$system->getFirstName($second_user->full_name).'";
$.get("'.$system->getDomain().'/ajax/refreshChat.php?id="+id+"&receiver="+receiver, function(data) {
$(".conversation-content").html(data);
});
var scroller = $(".conversation-message-list").getNiceScroll(0);
$(".conversation-message-list").getNiceScroll(0).doScrollTop($(".conversation-content").height(),-1);
}
window.setInterval(function(){
refreshChat();
}, 2000);
function sendMessage() {
var user2 = "'.$user2.'";
var message = $("#message");
if(message.val() != "" && message.val() != " ") {
$.get("'.$system->getDomain().'/ajax/sendMessage.php?id="+user2+"&msg="+encodeURIComponent(message.val()), function(data) {
$(".conversation-content").html(data);
message.val("");
});
}
}
$(document).keypress(function(e) {
if(e.which == 13) {
sendMessage();
}
});
</script>
Right now, the refreshChat function calls an ajax script every 2 seconds. When you have entered a message and press enter, it calls a different ajax script. What I would like it to do, is call both functions at the same time. So the script calls the sendMessage function first and refreshes afterwards.
How can I do this? I have already tried changing it to:
<script>
function refreshChat() {
var id = "'.$convers_id.'";
var receiver = "'.$system->getFirstName($second_user->full_name).'";
$.get("'.$system->getDomain().'/ajax/refreshChat.php?id="+id+"&receiver="+receiver, function(data) {
$(".conversation-content").html(data);
});
var scroller = $(".conversation-message-list").getNiceScroll(0);
$(".conversation-message-list").getNiceScroll(0).doScrollTop($(".conversation-content").height(),-1);
}
function sendMessage() {
var user2 = "'.$user2.'";
var message = $("#message");
if(message.val() != "" && message.val() != " ") {
$.get("'.$system->getDomain().'/ajax/sendMessage.php?id="+user2+"&msg="+encodeURIComponent(message.val()), function(data) {
$(".conversation-content").html(data);
message.val("");
});
}
}
$(document).keypress(function(e) {
if(e.which == 13) {
sendMessage();refreshChat();
}
});
</script>
But this only enters the message first, and it only refreshes on the second keypress (enter). I would like to thank everybody beforehand on helping me out.

This is actually an illusion. Both functions are being called, but the chat window is refreshing before the chat message is able to save them.
To fix this, you should refresh the chat window only once the new message has been successfully saved:
function refreshChat() {
// Removed for brevity
}
function sendMessage() {
var user2 = "'.$user2.'";
var message = $("#message");
if(message.val() != "" && message.val() != " ") {
$.get("'.$system->getDomain().'/ajax/sendMessage.php?id="+user2+"&msg="+encodeURIComponent(message.val()), function(data) {
$(".conversation-content").html(data);
message.val("");
// Now, this will only be called once the ajax is complete
refreshChat();
});
}
}
$(document).keypress(function(e) {
if(e.which == 13) {
sendMessage();
// I removed the refreshChat() call from here and moved it
// into the $.get() callback above ^^
}
});
As you can see, I moved your refreshChat() method to now be called from within the jQuery $.get() callback.

Have you tried using callbacks, that may be what you need?

MY WORKING AWNSER
Considering for what i asked, i have marked Wes Foster's awnser as correct. What made it work for me is also applying a promises after the get function. This way, the ajax script get's called twice as needed. I hope it will help someone in the future. (Look at me... travelling through time...). You will find my code underneath:
function refreshChat() {
var id = "'.$convers_id.'";
var receiver = "'.$system->getFirstName($second_user->full_name).'";
$.get("'.$system->getDomain().'/ajax/refreshChat.php?id="+id+"&receiver="+receiver, function(data) {
$(".conversation-content").html(data);
});
var scroller = $(".conversation-message-list").getNiceScroll(0);
$(".conversation-message-list").getNiceScroll(0).doScrollTop($(".conversation-content").height(),-1);
}
function sendMessage() {
var user2 = "'.$user2.'";
var message = $("#message");
if(message.val() != "" && message.val() != " ") {
$.get("'.$system->getDomain().'/ajax/sendMessage.php?id="+user2+"&msg="+encodeURIComponent(message.val()), function(data) {
$(".conversation-content").html(data);
message.val("");
refreshChat();
}).done(refreshChat);
}
}
$(document).keypress(function(e) {
if(e.which == 13) {
sendMessage();
}
});

The problem is that the console (developer tool panel) needs to be active on page-load*.
Hit F12, reload your page, and you should get what you're looking for.
*Just to clarify: The developer panel needs to be open prior to window.console being called/tested. I'm assuming your code is being run on-load.

This should work:
if(!window.console || !window.console.log) window.console = {log: function(){}};
This way you will be able to use console.log without producing errors.

In my code, I put this snippet at the top - before any other javascript that might try to use the console loads:
if (window.console == null) {
window.console = {
log: function() {},
warn: function() {},
info: function() {},
error: function() {}
};
}
Or in coffeescript:
if not window.console?
window.console = {
log: () ->
warn: () ->
info: () ->
error: () ->
}
This provides a dummy console for browsers that don't include one.

Page loading is gradually getting slower using jQuery script

I'm using this jQuery script to show search results. Everything works fine, but when search results have more than one page and I'm browsing pages via paging then every page loading is gradually getting slower. Usually first cca 10 pages loads I get quickly, but next are getting avoiding loading delay. Whole website get frozen for a little while (also loader image), but browser is not yet. What should be the problem?
function editResults(def) {
$('.searchResults').html('<p class=\'loader\'><img src=\'images/loader.gif\' /></p>');
var url = def;
var url = url + "&categories=";
// Parse Categories
$('input[name=chCat[]]').each(function() {
if (this.checked == true) {
url = url + this.value + ",";
}
});
url = url + "&sizes=";
// Parse Sizes
$('input[name=chSize[]]').each(function() {
if (this.checked == true) {
url = url + this.value + ",";
}
});
url = url + "&prices=";
// Parse Prices
$('input[name=chPrice[]]').each(function() {
if (this.checked == true) {
url = url + this.value + ",";
}
});
$('.searchResults').load('results.php'+url);
$('.pageLinks').live("click", function() {
var page = this.title;
editResults("?page="+page);
});
}
$(document).ready(function(){
editResults("?page=1");
// Check All Categories
$('input[name=chCat[0]]').click(function() {
check_status = $('input[name=chCat[0]]').attr("checked");
$('input[name=chCat[]]').each(function() {
this.checked = check_status;
});
});
// Check All Sizes
$('input[name=chSize[0]]').click(function() {
check_status = $('input[name=chSize[0]]').attr("checked");
$('input[name=chSize[]]').each(function() {
this.checked = check_status;
});
});
// Edit Results
$('.checkbox').change(function() {
editResults("?page=1");
});
// Change Type
$(".sort").change(function() {
editResults("?page=1&sort="+$(this).val());
});
});

$('.pageLinks').live("click", function() {
var page = this.title;
editResults("?page="+page);
});
just a wild guess but... wouldn't this piece of code add a new event handler to the click event instead reaplacing the old one with a new one? causing the click to call all the once registered handlers.
you should make the event binding just once
var global_var = '1';
function editResults(def) {
// all your code
global_var = 2; // what ever page goes next
};
$(document).ready(function() {
// all your code ...
$('.pageLinks').live("click", function() {
var page = global_var;
editResults("?page="+page);
});
});

How to submit a form using PhantomJS

I'm trying to use phantomJS (what an awesome tool btw!) to submit a form for a page that I have login credentials for, and then output the content of the destination page to stdout. I'm able to access the form and set its values successfully using phantom, but I'm not quite sure what the right syntax is to submit the form and output the content of the subsequent page. What I have so far is:
var page = new WebPage();
var url = phantom.args[0];
page.open(url, function (status) {
if (status !== 'success') {
console.log('Unable to access network');
} else {
console.log(page.evaluate(function () {
var arr = document.getElementsByClassName("login-form");
var i;
for (i=0; i < arr.length; i++) {
if (arr[i].getAttribute('method') == "POST") {
arr[i].elements["email"].value="mylogin#somedomain.example";
arr[i].elements["password"].value="mypassword";
// This part doesn't seem to work. It returns the content
// of the current page, not the content of the page after
// the submit has been executed. Am I correctly instrumenting
// the submit in Phantom?
arr[i].submit();
return document.querySelectorAll('html')[0].outerHTML;
}
}
return "failed :-(";
}));
}
phantom.exit();
}

I figured it out. Basically it's an async issue. You can't just submit and expect to render the subsequent page immediately. You have to wait until the onLoad event for the next page is triggered. My code is below:
var page = new WebPage(), testindex = 0, loadInProgress = false;
page.onConsoleMessage = function(msg) {
console.log(msg);
};
page.onLoadStarted = function() {
loadInProgress = true;
console.log("load started");
};
page.onLoadFinished = function() {
loadInProgress = false;
console.log("load finished");
};
var steps = [
function() {
//Load Login Page
page.open("https://website.example/theformpage/");
},
function() {
//Enter Credentials
page.evaluate(function() {
var arr = document.getElementsByClassName("login-form");
var i;
for (i=0; i < arr.length; i++) {
if (arr[i].getAttribute('method') == "POST") {
arr[i].elements["email"].value="mylogin";
arr[i].elements["password"].value="mypassword";
return;
}
}
});
},
function() {
//Login
page.evaluate(function() {
var arr = document.getElementsByClassName("login-form");
var i;
for (i=0; i < arr.length; i++) {
if (arr[i].getAttribute('method') == "POST") {
arr[i].submit();
return;
}
}
});
},
function() {
// Output content of page to stdout after form has been submitted
page.evaluate(function() {
console.log(document.querySelectorAll('html')[0].outerHTML);
});
}
];
interval = setInterval(function() {
if (!loadInProgress && typeof steps[testindex] == "function") {
console.log("step " + (testindex + 1));
steps[testindex]();
testindex++;
}
if (typeof steps[testindex] != "function") {
console.log("test complete!");
phantom.exit();
}
}, 50);

Also, CasperJS provides a nice high-level interface for navigation in PhantomJS, including clicking on links and filling out forms.
CasperJS
Updated to add July 28, 2015 article comparing PhantomJS and CasperJS.
(Thanks to commenter Mr. M!)

Sending raw POST requests can be sometimes more convenient. Below you can see post.js original example from PhantomJS
// Example using HTTP POST operation
var page = require('webpage').create(),
server = 'http://posttestserver.example/post.php?dump',
data = 'universe=expanding&answer=42';
page.open(server, 'post', data, function (status) {
if (status !== 'success') {
console.log('Unable to post!');
} else {
console.log(page.content);
}
phantom.exit();
});

As it was mentioned above CasperJS is the best tool to fill and send forms.
Simplest possible example of how to fill & submit form using fill() function:
casper.start("http://example.com/login", function() {
//searches and fills the form with id="loginForm"
this.fill('form#loginForm', {
'login': 'admin',
'password': '12345678'
}, true);
this.evaluate(function(){
//trigger click event on submit button
document.querySelector('input[type="submit"]').click();
});
});
