How to get my desired cryptocurrencies working in this JavaScript widget? - javascript

I have a problem when trying to use a widget.
The script is as follows:
<script type="text/javascript">
baseUrl = "https://widgets.cryptocompare.com/";
var scripts = document.getElementsByTagName("script");
var embedder = scripts[ scripts.length - 1 ];
(function (){
var appName = encodeURIComponent(window.location.hostname);
if(appName==""){appName="local";}
var s = document.createElement("script");
s.type = "text/javascript";
s.async = true;
var theUrl = baseUrl+'serve/v3/coin/chart?fsym=TPAY*&tsyms=USD';
s.src = theUrl + ( theUrl.indexOf("?") >= 0 ? "&" : "?") + "app=" + appName;
embedder.parentNode.appendChild(s);
})();
</script>
When I access https://widgets.cryptocompare.com/serve/v3/coin/chart?fsym=TPAY*&tsyms=USD from my browser it displays all the data but when using the widget script it does not seem to like the fsym=TPAY&tsym=USD but because cryptocompare lists some currencies that have the same ticker they add a * to the second currency which uses the same ticker name.
Another example of this is PHORE PHR* as they have PHREAK PHR already listed. Funny enough the currencies I would like to use it TPAY* and PHR*.

head.appendChild giving error in console but working fine

I am trying to inject a script on page load in head wherein I have to give the page name inside script.
Below is how I am implementing it in my ts file.
**var head = document.getElementsByTagName('head')[0];
var tag = document.createElement("script");
tag.type = 'text/javascript';
tag.innerHTML = "var DDO = {} DDO.pageData = {'pageName': " + pageUrl + "} ";
head.appendChild(tag);**
The script is getting injected however an error is being thrown in the console tab.
ERROR: VM3741:1 Uncaught SyntaxError: Unexpected identifier at appendChild
Try this
var head = document.getElementsByTagName('head')[0],pageUrl="somevalue";
var tag = document.createElement("script");
tag.type = 'text/javascript';
tag.textContent = "var DDO = {}; DDO.pageData = {'pageName': '" + pageUrl + "'} ";
head.appendChild(tag);
To remove previous script element
var script = head.childNodes[0]; //get previous script element
head.removeChild(script); //removing script
you have not provided single quotes for the value of the key pageName
tag.innerHTML = "var DDO = {}; DDO.pageData = {'pageName': " + pageUrl + "} ";
semicolon missing after defining the variable DDO,
and also from where are you injecting in pageUrl, make sure variable is defined.
try having script in external file and injecting in script tag with refrence to that file in case some error in script defined in inner html
document.head, document.body to attach scripts
Correct Answer:
var head = document.getElementsByTagName('head')[0];
var tag = document.createElement('script');
tag.type = 'text/javascript';
tag.id = 'adobedatalayer';
tag.textContent = 'var DDO = {}; DDO.pageData =' + JSON.stringify(pageinfo);
var script = document.getElementById('adobedatalayer');
if (script != null) {
head.removeChild(script);
}
head.appendChild(tag);

call normal javascript using angualrjs

I'm trying to include legacy javascript code for affiliate tracking into an angularjs app
<script type="text/javascript">
//<![CDATA[
/*** Do not change ***/
var AWIN = {};
AWIN.Tracking = {};
AWIN.Tracking.Sale = {};
/*** Set your transaction parameters ***/
AWIN.Tracking.Sale.amount = '{{order_total}}';
AWIN.Tracking.Sale.orderRef = '{(order_id}}';
AWIN.Tracking.Sale.parts = '{{cats}}';
AWIN.Tracking.Sale.voucher = '';
AWIN.Tracking.Sale.currency = 'GBP';
AWIN.Tracking.Sale.test = '0';
AWIN.Tracking.Sale.channel = 'aw';
//]]>
</script>
I need to call the above code (filling in the place holders with angualr vars) and then call this:
<script src="https://www.dwin1.com/xxxx.js" type="text/javascript" defer="defer"></script>
What is the best way to do this? I've tried placing the code into an Angular function with no success I've also tried passing the vars down into $window and trying to insert them into the CDATA at my end with no success. Any ideas?
I should add this code sits in a HTML page wrapped in an angualrjs controller
what you are trying is not possible directly with angularjs. you need to do something like below
//Note: this is a new JS file included in your main html
(function() {
"use strict";
window.AWIN = {};
window.populateAwin = function(args) {
//<![CDATA[
/*** Do not change ***/
AWIN.Tracking = {};
AWIN.Tracking.Sale = {};
/*** Set your transaction parameters ***/
AWIN.Tracking.Sale.amount = args.order_total;
AWIN.Tracking.Sale.orderRef = args.order_id;
AWIN.Tracking.Sale.parts = args.cats;
AWIN.Tracking.Sale.voucher = '';
AWIN.Tracking.Sale.currency = 'GBP';
AWIN.Tracking.Sale.test = '0';
AWIN.Tracking.Sale.channel = 'aw';
//]]>
}
}());
you then need to call this function from your controller by passing required data as shown below
populateAwin({
order_total: $scope.order_total,
order_id: $scope.order_id,
cats: $scope.cats
});
Once this is done, you can proceed with inclusion of script dynamically as shown below from your controller
var scriptEl = document.createElement("script");
scriptEl.type = "text/javascript";
scriptEl.defer = "defer";
scriptEl.src = "https://www.dwin1.com/xxxx.js";
document.body.appendChild(scriptEl);

Different UI script to execute depending on URL

I have my UI's split up in 2 javascript files. If the URL is of certain patter lets say /test1 then I want script1 to execute or in other words, I want script1 to be added as <include> so the UI renders according to script1 else I want script2 to be added for /test2.
There is no button that triggers these URLs. Its when the page loads -detect URL and load script accordingly.
How can I achieve this?
you can dynamically insert javascript file.
<script type="application/javascript">
function loadJS(file) {
// DOM: Create the script element
var jsElm = document.createElement("script");
// set the type attribute
jsElm.type = "application/javascript";
// make the script element load file
jsElm.src = file;
// finally insert the element to the body element in order to load the script
document.body.appendChild(jsElm);
}
if(type === "test1")
loadJS('file1.js')
else
loadJS('file2.js');
</script>
using jquery and javascript:
$(document).ready(function(){
var url=location.href//get the page url
var scriptUrl
if(url.indexOf('something')>0){//check for specific string in url
scriptUrl='/script1.js'
}
else{
scriptUrl='/script2.js'
}
var script = document.createElement( 'script' );//create script element
script.type = 'text/javascript';
script.src = scriptUrl;
$("head").append( script );//append newly created script element to head
})
Query String Examples:
?page=test1
?page=test2
Following code will check the value of page and then load the appropriate Script:
$(document).ready(function () {
var page = $.getUrlVar("page");
var scriptToRun = null;
switch (page) {
case "test1":
scriptToRun = "script1.js";
break;
case "test2":
scriptToRun = "script2.js";
break;
}
// Create Script Tag
var script = document.createElement('script');
script.type = 'text/javascript';
script.src = scriptToRun;
$("head").append(script);
});
Be sure to add the following Extension before your $(document).ready code:
$.extend({
getUrlVars: function(){
var vars = [], hash;
var hashes = window.location.href.slice(window.location.href.indexOf('?') + 1).split('&');
for(var i = 0; i < hashes.length; i++) {
hash = hashes[i].split('=');
vars.push(hash[0]);
vars[hash[0]] = hash[1];
}
return vars;
},
getUrlVar: function(name){
return $.getUrlVars()[name];
}
});
(This jQuery Extension is not my Code).

Getting twitter shares count, response giving weird output

//this function is the callback, it needs to be a global variable
window.readResponse = function (response){
document.getElementsByTagName('SPAN')[0].innerHTML = response;
}
(function(){
//note the "readResponse" at the end
$URL = "http://www.google.com/"
var src = 'http://cdn.api.twitter.com/1/urls/count.json?url=' + $URL + '&callback=readResponse',
script = document.createElement('SCRIPT');
script.src = src;
document.body.appendChild(script);
})();
That above is my codes to get the shares count. But when I do the request, the response I am getting is
function (){ //note the "readResponse" at the end $URL = "http://www.google.com/" var src = 'http://cdn.api.twitter.com/1/urls/count.json?url=' + $URL + '&callback=readResponse', script = document.createElement('SCRIPT'); script.src = src; document.body.appendChild(script); }
Where as I am expecting the response.count is the actual share count.
I setup a demo here http://jsfiddle.net/zs1dgs45/5/
Any help would be appreciated
Twitter have stopped supporting the share count API. Sorry.

Inserting Google Adwords Conversion Tracking with Javascript or jQuery

I'm pretty new to javascript, and therein probably lies my problem. I'm trying to track AdWords conversions that occur within a widget on our site. The user fills in a form and the result from the widget is published in the same div without a page refresh. The issue I'm having is when I try to appendChild (or append in jQuery) both script elements in Google's code (shown below) the page gets 302 redirected to a blank Google page (or at least that's what it looks like through FireBug).
I'm able to provide a callback method for the results of the form, and that's where I'm trying to insert the AdWords tracking code. For reference, this is the code provided by Google:
<script type="text/javascript">
/* <![CDATA[ */
var google_conversion_id = 993834405;
var google_conversion_language = "en";
var google_conversion_format = "3";
var google_conversion_color = "ffffff";
var google_conversion_label = "bSpUCOP9iAIQpevy2QM";
/* ]]> */
</script>
<script type="text/javascript" src="http://www.googleadservices.com/pagead/conversion.js">
</script>
<noscript>
<div style="display:inline;">
<img height="1" width="1" style="border-style:none;" alt="" src="http://www.googleadservices.com/pagead/conversion/993834405/?label=bSpUCOP9iAIQpevy2QM&guid=ON&script=0"/>
</div>
</noscript>
Pretty standard stuff. So, what I'm trying to do is insert this into the results page using the callback method (which is provided). Frankly, I'm redirected no matter when I try to insert this code using js or jQuery (either on original page load or in the callback) so maybe the callback bit is irrelevant, but it's why I'm not just pasting it into the page's code.
I've tried a number of different ways to do this, but here's what I currently have (excuse the sloppiness. Just trying to hack my way through this at the moment!):
function matchResultsCallback(data){
var scriptTag = document.createElement('script');
scriptTag.type = "text/javascript";
scriptTag.text = scriptTag.text + "/* <![CDATA[ */\n";
scriptTag.text = scriptTag.text + "var google_conversion_id \= 993834405\;\n";
scriptTag.text = scriptTag.text + "var google_conversion_language \= \"en\"\;\n";
scriptTag.text = scriptTag.text + "var google_conversion_format \= \"3\"\;\n";
scriptTag.text = scriptTag.text + "var google_conversion_color \= \"ffffff\"\;\n";
scriptTag.text = scriptTag.text + "var google_conversion_label \= \"bSpUCOP9iAIQpevy2QM\"\;\n";
scriptTag.text = scriptTag.text + "/* ]]> */\n";
$('body').append(scriptTag);
$('body').append("<script type\=\"text\/javascript\" src\=\"http://www.googleadservices.com/pagead/conversion.js\" />");
//I have also tried this bit above using the same method as 'scriptTag' with no luck, this is just the most recent iteration.
var scriptTag2 = document.createElement('noscript');
var imgTag = document.createElement('img');
imgTag.height = 1;
imgTag.width = 1;
imgTag.border = 0;
imgTag.src = "http://www.googleadservices.com/pagead/conversion/993834405/?label=bSpUCOP9iAIQpevy2QM&guid=ON&script=0";
$('body').append(scriptTag2);
$('noscript').append(imgTag);
}
The really odd thing is that when I only insert one of the script tags (it doesn't matter which one), it doesn't redirect. It only redirects when I try to insert both of them.
I've also tried putting the first script tag into the original page code (as it's not making any calls anywhere, it's just setting variables) and just inserting the conversions.js file and it still does the redirect.
If it's relevant I'm using Firefox 3.6.13, and have tried the included code with both jQuery 1.3 and 1.5 (after realizing we were using v1.3).
I know I'm missing something! Any suggestions?
Nowadays it is convenient to use the Asynchronous Tag at http://www.googleadservices.com/pagead/conversion_async.js that exposes the window.google_trackConversion function.
This function can be used at any time. For example after submitting a form, like in your case.
See https://developers.google.com/adwords-remarketing-tag/asynchronous/
Update 2018
Situation changed and it seems that you have more options now with the gtag.js: https://developers.google.com/adwords-remarketing-tag/
If you're using jQuery in your pages, why don't you use the getScript method of the same to poll the conversion tracking script after setting the required variables?
This is what I usually do, once I've received a success response from my AJAX calls.
var google_conversion_id = <Your ID Here>;
var google_conversion_language = "en";
var google_conversion_format = "3";
var google_conversion_color = "ffffff";
var google_conversion_label = "<Your Label here>";
var google_conversion_value = 0;
if (100) {
google_conversion_value = <Your value here if any>;
}
$jQ.getScript( "http://www.googleadservices.com/pagead/conversion.js" );
This works just fine for me. If you want a more detailed example:
$.ajax({
async: true,
type: "POST",
dataType: "json",
url: <Your URL>,
data: _data,
success: function( json ) {
// Do something
// ...
// Track conversion
var google_conversion_id = <Your ID Here>;
var google_conversion_language = "en";
var google_conversion_format = "3";
var google_conversion_color = "ffffff";
var google_conversion_label = "<Your Label here>";
var google_conversion_value = 0;
if (100) {
google_conversion_value = <Your value here if any>;
}
$.getScript( "http://www.googleadservices.com/pagead/conversion.js" );
} // success
});
If you use other libraries such as Mootools or Prototype, I'm sure they have similar in-built methods. This AFAIK is one of the cleanest approaches.
this simple code worked for me (the $.getScript version didn't).
var image = new Image(1,1);
image.src = 'http://www.googleadservices.com/pagead/conversion/' + id + '/?label=' + label + ' &guid=ON&script=0';
// This takes care of it for jQuery. Code can be easily adapted for other javascript libraries:
function googleTrackingPixel() {
// set google variables as globals
window.google_conversion_id = 1117861175
window.google_conversion_language = "en"
window.google_conversion_format = "3"
window.google_conversion_color = "ffffff"
window.google_conversion_label = "Ll49CJnRpgUQ9-at5QM"
window.google_conversion_value = 0
var oldDocWrite = document.write // save old doc write
document.write = function(node){ // change doc write to be friendlier, temporary
$("body").append(node)
}
$.getScript("http://www.googleadservices.com/pagead/conversion.js", function() {
setTimeout(function() { // let the above script run, then replace doc.write
document.write = oldDocWrite
}, 100)
})
}
// and you would call it in your script on the event like so:
$("button").click( function() {
googleTrackingPixel()
})
In your Adwords account - if you change the conversion tracking event to "Click" instead of "Page Load" it will provide you with code that creates a function. It creates a snippet like this:
<!-- Google Code for Developer Contact Form Conversion Page
In your html page, add the snippet and call
goog_report_conversion when someone clicks on the
chosen link or button. -->
<script type="text/javascript">
/* <![CDATA[ */
goog_snippet_vars = function() {
var w = window;
w.google_conversion_id = <Your ID Here>;
w.google_conversion_label = "<Your value here if any>";
w.google_remarketing_only = false;
}
// DO NOT CHANGE THE CODE BELOW.
goog_report_conversion = function(url) {
goog_snippet_vars();
window.google_conversion_format = "3";
window.google_is_call = true;
var opt = new Object();
opt.onload_callback = function() {
if (typeof(url) != 'undefined') {
window.location = url;
}
}
var conv_handler = window['google_trackConversion'];
if (typeof(conv_handler) == 'function') {
conv_handler(opt);
}
}
/* ]]> */
</script>
<script type="text/javascript"
src="//www.googleadservices.com/pagead/conversion_async.js">
</script>
Then in your code you just call:
goog_report_conversion();
Or for a link or image click:
click here
After trying everything the link Funka provided (http://articles.adamwrobel.com/2010/12/23/trigger-adwords-conversion-on-javascript-event) was what worked for me. Like he said it's scary to overwrite document.write, but
It seems like this is what you have to do unless you can load the script before the page load.
Since the script uses document.write so it needs to be re-written
document.write = function(node){ // exactly what document.write should of been doing..
$("body").append(node);
}
window.google_tag_params = {
prodid: pageId,
pagetype: pageTypes[pageType] || "",
value: "234324342"
};
window.google_conversion_id = 2324849237;
window.google_conversion_label = "u38234j32423j432kj4";
window.google_custom_params = window.google_tag_params;
window.google_remarketing_only = true;
$.getScript("http://www.googleadservices.com/pagead/conversion.js")
.done(function() {
// script is loaded.
});
See https://gist.github.com/c7a316972128250d278c
As you have seen, the google conversion tag only calls on a redraw. I had to make sure it was called when a part of a page was redrawn. (Due to some bad website design that I could not fix at the moment.) So I wrote a function to call from an onClick event.
Essentially, all you have to do is to call doConversion();
Here is what we ended up with:
// gothelp from from http://www.ewanheming.com/2012/01/web-analytics/website-tracking/adwords-page-event-conversion-tracking
var Goal = function(id, label, value, url) {
this.id = id;
this.label = label;
this.value = value;
this.url = url;
};
function trackAdWordsConversion(goal, callback) {
// Create an image
var img = document.createElement("img");
// An optional callback function to run follow up processed after the conversion has been tracked
if(callback && typeof callback === "function") {
img.onload = callback;
}
// Construct the tracking beacon using the goal parameters
var trackingUrl = "http://www.googleadservices.com/pagead/conversion/"+goal.id;
trackingUrl += "/?random="+new Date().getMilliseconds();
trackingUrl += "&value="+goal.value;
trackingUrl += "&label="+goal.label;
trackingUrl += "&guid=ON&script=0&url="+encodeURI(goal.url);
img.src = trackingUrl;
// Add the image to the page
document.body.appendChild(img);
// Don't display the image
img.style = "display: none;";
}
function linkClick(link, goal) {
try {
// A function to redirect the user after the conversion event has been sent
var linkClickCallback = function() {
window.location = link.href;
};
// Track the conversion
trackAdWordsConversion(goal, linkClickCallback);
// Don't keep the user waiting too long in case there are problems
setTimeout(linkClickCallback, 1000);
// Stop the default link click
return false;
} catch(err) {
// Ensure the user is still redirected if there's an unexpected error in the code
return true;
}
}
function doConversion() {
var g = new Goal(YOUR CODE,YOUR_COOKIE,0.0,location.href);
return linkClick(this,g);
}
I tried all the ways to manually include conversion.js, it all loaded the script, but didn't further execute what we needed inside the script, there's a simple solution.
Just put your conversion code in a separate HTML, and load it in an iframe.
I found code to do that at http://www.benjaminkim.com/ that seemed to work well.
function ppcconversion() {
var iframe = document.createElement('iframe');
iframe.style.width = '0px';
iframe.style.height = '0px';
document.body.appendChild(iframe);
iframe.src = '/track.html'; // put URL to tracking code here.
};
then just call ppcconversion() wherever in the JS you like to record it.
All I do is return the code (or in our case, an image) along with the "success" message in the callback.
When a contact form is submitted, or a registration form filled out and submitted, we post to a php script using jQuery, then output a "thank-you" message to a div:
"$first_name, Thanks for requesting more information. A representative will contact you shortly."
... followed by the 1x1 gif Google provides.
Here's the jQuery:
$.post('script.php',{'first_name':first_name,'last_name':last_name,'email':email,'phone1':phone1,'password':password,},function(data){
var result=data.split("|");
if(result[0] ==='success'){
$('#return').html(result[1] + $result[2]);
And the php...
echo 'success|'.$first_name.', Thanks for requesting more information.
A representative will contact you shortly.|<img height="1" width="1" alt="" src="http://www.googleadservices.com/pagead/conversion/xxxxxxxx/imp.gif?value=0&label=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx&script=0"/>';
You might need to throw in a "document.location.reload();" if it isn't being picked up by google
For anyone still looking for a good solution to this, Google supports AJAX Conversions natively now through their Google Analytics API.
You can do it by making a event API call in Google Analytics. What you do is setup an Analytics event, tie it to a goal, then import that goal into AdWords as a conversion. It's a bit of a lengthy process but it's a clean solution.
Check out This Page for a tutorial
This works for me:
window.google_trackConversion({
google_conversion_id: 000000000,
conversion_label : "xxxxxxxxxxxx",
google_remarketing_only: false,
onload_callback : function(){
//do something :)
}
});
