For some reason when I add a HTML module (well the default module added to DNN 5.4) and then add the "AddThis" javascript. While the button shows up clicking on it opens up a new page rather than showing an iframe modal message or on hover a list of popular social media networks to share the page with. Wonder what would be the easiest way to resolve this and why this happens?
This is not a complete answer, but to me it sounds like the AddThis javascript code is never loaded by the browser. When viewing the web page that doesn't workg, open the HTML source and look for the AddThis script tag. It probably should look something like this:
<script type="text/javascript" src="http://s7.addthis.com/js/250/addthis_widget.js#username=..."></script>
If you can not find it, then there is something to work on. If you find it, try to open the URL in your browser and see if you get the javascript.
Otherwise: as always, FireBug (or the tools in IE8) is your friend.
Try copying the addthis script reference and pasting it to the page header tags:
http://s7.addthis.com/js/250/addthis_widget.js#pub=AddThis

Now I have a block of JavaScript code to change the display of a webpage, say to highlight some data so that when I read the webpage I can easily find them.
The code is super simple, you can just imagine it as
document.getElementById(index).classList.add("highlight")
index is used to find the content needing to be changed. I will append highlight class to the class attribute of found content so that the display would be changed (just for illustration of the purpose)
Now the problem is, whenever I open the webpage, I need to copy and paste this code to console in Chrome and run it, which is troublesome. So I am wondering whether it is possible that the Chrome will run this script automatically when I load the webpage. Say for example, I have a hyperlink directs to the webpage and when I click the hyperlink, the script will be run and the display of the webpage will be changed.
Tampermonkey is not really helpful in my case. I have another method to generate the JavaScript for different webpages so the script I want to run will change when I load different webpages.
There are some tools for this purpose you can use:
TamperMonkey
Tampermonkey is the most popular userscript manager, with over 10 million users.
RunJS
RunJS is a developer tool that allows users to debug pages by running specified JS across all page loads.
I highly recommend User CSS and Javascript chrome extension. I have been using it for years with no issues whatsoever. In fact, I have customized the vast majority of the websites I use on a daily basis using it!
You could actually use a bookmarklet which should simplify the process. https://gist.github.com/caseywatts/c0cec1f89ccdb8b469b1. If you want to fully automate it however you need to create a plugin
yes there is, try following code.
<script>
window.onload = function(){
alert("ready");
// place your code here ...
}
</script>
or just write your code at the bottom of file, like this
<html>
<head></head>
<body>
<!-- any html tags here -->
<script>
// any JS code here
</script>
</body>
</html>
I've a strange behavior with my web site.
When I open a page (any page) the code is loaded but browser display the content only after few seconds.
I've tried to print a console.log to see when it appear, and it appear after the code is loaded, as I expect it to do, but the content of the page is display after few seconds...
This behavior occurs when I switch my web site to a specific language, while with the other language everythings works fine.
The code is the same except for the text.
Do you know why?
Maybe the i18n system you are using require a little time to map the frontend string with translation, without full code snippet that reproduce the issue is difficult to tell.
no, I've found that the problem is the script of google optimizer...
I loaded the script but I didn't use ga('require', 'optimezer_coded') for this language.
If I remove the script that load optimezer or I insert ga('require', 'optimezer_coded') it works.
I have an issue that on certain pages of my website no tags are included in the GTM container. The debugger shows: "There are no tags in the container." I'm trying now for weeks to find the solution but no chance. I would really appreciate any ideas!
I have included for example the Google Universal code on all pages:
url matches RegEx .*
Usually on the start page and some other pages no tags are included:
http://www.ailolaquito.com
On other pages like this the tags usually are included:
http://www.ailolaquito.com/en/activities/spanish-and-dancing
When I use the GTM Preview and Debugger tool it first shows above message and when I open the Data Layer tab and switch back to the Tags tab, suddenly all tags are shown as they should. Maybe there is a conflict (JavaScript?) on some pages.
What I noticed is that on all pages where the tags are not included the HTML code in the source view of Safari looks compressed:
While on pages where the tags are properly shown the html source looks nice:
Probably it's related with this. However I don't understand why the source code is compressed on some pages. They are all based on the same layout templates.
Any ideas or help would be appreciated. I really would like to solve the issue.
Thanks a lot!

for the answer see https://plus.google.com/102446957955231069158/posts/FetKoAh2JrD "there is a race condition that we are currently hunting down that when the debug script is cached you can see the no tags message. But if you click on any of the events and you can see what fired. Once you navigate to an event the summary tab will display correctly again. You can also force refresh the page which seams to fix this also." by Michael Philpott
Are you able to see the coding of a Javascript function on a webpage your viewing? Is there a way using Google Chrome DevTools for example?
Specifically, I want to figure out how to code something like this
!Example 1
from this page

Thanks in advance for any help!
Yes there is a way to look at all of a webpages html, Javascript files, and CSS using Chrome.
Open up the page in chrome, right click on the page and select inspect element (or press ctrl+shift+I).
From there you can navigate the different elements on the the page and the structure of the HTML file.
To get at the Javascript and CSS files switch over to the sources tab and look through the folders on the left to find the file you are looking for.
A word of warning, depending on the site the code that they are using may be minified (most all of the white space removed, and lots of variable names and other things shortened) or otherwise very difficult to read. If you are looking to do something more specific then I would recommend searching for that, or posting a question regarding that problem.
If you want to view the Javascript code, you can right-click the page, then select Inspect, then navigate to the javascript line by highlighting or selecting that line with .js extension and then position your pointer in the .js file, right-click & select Reveal in Sources panel.
In the browser you do right click to open a menu and select "View Source Code". Then you can read or save that page to analyze the content for any image or script.
But your question is so generic maybe you should try something basic and try to builds thing from there. Otherwise make a more specific question of what you want to do.
You can check it by opening the inspector in your browser and selecting the "coverage" menu. Then click on the "type" column until you find the .js files.
It is pretty much it, but you can read more details here: https://developer.chrome.com/docs/devtools/coverage/
I have developed a small component which can be put in to any website. Now, I want to develop a code that could demonstrate how would my component look like on any website.
So, the person would come to my page and put in his URL and then my code should embed my custom JS/CSS in to the downloaded HTML and display it. Something like this.
Here, like the feedback tab, I want to show my component any where on that page.
Try a bookmarklet.
Create a piece of javascript that adds your code into the page such as the following:
javascript:(function(){var%20script=document.createElement('script');script.src='http://www.example.org/js/example.js';document.getElementsByTagName('head')[0].appendChild(script);})()
Add it as the href of a link like so:
Link Text Here
Tell your users to drag the link to their bookmark toolbar and click on it on different websites to try your code out.
Some examples: http://www.reclaimprivacy.org/, http://www.readability.com/bookmarklets
In the example you linked, they are requesting the page specified in the url querystring parameter on the server, and then doing more or less the following steps:
In the <head> tag they are adding a <base href="url" /> tag to the document. The base tag will make any relative links in the document treat the value in the href attribute as their root. This is how they are getting around broken css / images. (The base tag is supported by all browsers)
At the end of the document (IE the </body> tag) they are injecting the javascript that runs their demos.
They serve the modified HTML requested to the browser.
All of this is pretty straight forward in implementation. You could use regular expressions to match the <head> and </body> tags for steps 1 and 2 respectively. Depending on the server platform how you actually request the page will vary, but here are some links to get you started:
C# - HttpWebRequest object documentation
PHP - HttpRequest::send
Nathan's answer is the closest to how we have done the demo feature at WebEngage. To make such a demo functional, you'll need to create a Javascript widget that can be embedded on third party sites. syserr0r's answer on creating a bookmarklet is the simplest approach to do so. Our's is a JAVA backend and we use HttpClient to fetch the responses. As Nathan suggested, we parse the response, sanitize it and add our widget Javascript to the response. The widget JS code takes it on from there to render the Feedback tab and load a demo short survey.
Disclosure: I am a co-founder and ceo at WebEngage.
You can not do this with JQuery due to cross site scripting restrictions.
I suggest you write a PHP script that downloads the URL specified by the user and includes your widget code and then echo it back to the user.
I recommend using bookmarklets. I've made a bookmarklet generator for adding jQuery-enabled bookmarklets to a page to make development easier.
There's a caliper bookmarklet on the page that you can mess around with just to show an example of it working.
Full disclosure, this is something I've made, I'm not trying to be spammy as I think it's relevant: zbooks
You could make an iframe page, which loads their page in the iframe, and uses javascript to inject your code into the iframe.
Here is my approach...
http://jsfiddle.net/L2kEf/
html
<iframe src="http://www.bing.com"></iframe>
<div>I am div</div>
css
div { background: red; position: absolute; top: 20px; width: 100px; left:20px;}
iframe{width: 100%; height: 500px;}
you can add javascript/jquery too, so you could do something like,
jQuery //not 100% sure it would work coz of cross browser thingy, but you know, worth a try.
$('div').click(function (){
$('iframe').contents().html('changed');///
});
if this can't change any of the contents, you can display a dialog, to say it would normally work if it was in your website, then use #syserr0r approach for bookmarked users, for better results, since you are offering this kinda services, to developers, im sure they would know about bookmarking, my approach would be rarely used :) so hope it helps.
I had a problem of a similiar nature, and the main obstacle is the cross-domain policy.
You have to ask the user to put your code in a <script src="..."> or create a proxy solution that would add your code for them.
I went for the proxy and here are my observations:
it's easy to create a basic proxy in php - there are some php proxies on sourceforge and Ben Alman has created a simple php proxy for AJAX. Based on those I was able to create a php proxy altering the content properly in one day.
after that I spent a lot of time making it work with more and more sites with issues. You can never create a perfect proxy.
As an alternative (sa long as you are non-commercial) you can use http://www.jmarshall.com/tools/cgiproxy/ and put the site in an iframe and then do whatever you want to do with the iframes document, as it's in your domain thanks to the proxy. You can access iframeDOMnode.contentWindow.document then, etc.
You can create a Crossrider extension which your users can download.
Then simply add this to your App/Extension code:
appAPI.dom.addRemoteJS("http://yourdomain.com/file.js")
Your users can then download the extension (it works cross-browser for Internet Explorer, Chrome and Firefox) and it will load your JS code on every page load.
You can get an approximation of what it will look like using a iframe. Take a look at that link for an example.
http://jsfiddle.net/jzaun/5PjRy/
The issue with this appoch is that you can't move your DIV(s) when the page scrolls, they are in effect just floating over the iframe. There is no way around this as cross-domain scripting wont let you access the iframe's document to monitor scroll events.
The only other option you have for a better fitting example would be to load the page from the server side in whatever scripting language you are using and load that into the iframe (or into a div, etc.) and you can use javascript all you want as the page is coming from your domain.
For your example of what will your widget look like I imagine floating your DIV(s) over an iframe would give enough of an idea.
Please note the example you gave is using the server side method, not the iframe method.
I agree with the bookmarklet strategy.
I'm a fan of http://bookmarklets.heroku.com/, which lets you generate bookmarklets easily, inject jQuery, etc.
