How to embed functionality into HTML email? - javascript

We want to let users click a thumbs up or thumbs down button from an HTML email, without causing the clicking to open a browser window.
Is there a way to essentially embed limited web functionality (i.e., clicking an icon, showing confirmation) within HTML emails?
Thanks!

I'm afraid such functionality, while theoretically possible, wouldn't be very practical given that most email clients strip out or disable JavaScript in order to prevent malicious code execution or other security issues. Your best bet is to use an image that looks like the thumbs up or thumbs down and then links directly back to your website. The browser window will still need to be opened, but you'll at least achieve the main part of your goal.

The short answer is no, not reliably across email clients. Usually with something like this I'd embed an image that looked like your functional element and just have it link to a web page that has that functional element.

Fancybox - implementing backward and forward for iFrames

I'm using Fancybox to display webpages through an iFrame. Those webpages are like a little information network: they're calling each other via links, and the user can circle through them.
I wanted to implement back et forth buttons: I did it by putting those buttons directly inside the displayed page, and working with the history (history.go(-1)) : that works, as long as the browser behaves in the way they do with iFrames.
However, there's a problem: if the user clicks on the back button and is on the first page of his navigation, it will bring him back out of the website itself (as, out of the fancy box, it's a one-page website).
As for security purpose you cannot have access to the history and test it to avoid that, is there a way to find out if the user will get out of the domain if he does a step more? Document.referent doesn't seem to work in the context of Fancybox and iFrames…
Thanks A LOT, I tried many (mainly stupid things), including a javascript session with window.name (see how desperate I am ?) !

How to keep audio playing while navigating through pages?

I am making a website for my friends band. I would like to know if its possible (apart from using Ajax) to keep audio playing after clicking on a link to another page on the site?
I currently have it set up using Ajax to reload the content, but I am having a few issues with it, and I'd rather not deal with the bother unless I really have to.
If not possible, is there a way to minimise the disruption (pausing then playing again) while navigating? It would be possible for the new page to continue playing the track from where the last page stopped, but I would like to minimise the pause. Or, on this subject, is it possible to keep certain page elements loaded after changing the URL (without using # urls), like facebook does (as in, you click on it, but the banner never disappears during loading)
Thanks for any help :)
Use Ajax to load content and History API’s pushState() to alter URL without page reload.
For consistent behavior across browsers, consider using a wrapper library like History.js.
Sites like Facebook use JavaScript/AJAX for these kind of things. If you don't want to use it, you can use frames (not recommended). Divide the page in two frames: the player and the website itself. This way you can easily turn it off too, just open the site without frames.
Good luck!
Of course you could also pop up the player in another window/tab.
(For now) It won't be possible without frames or javascript.
It might be troublesome to implement it differently than via AJAX, however you can either use IFrames, where the music would be played in the main one and the content is displayed in the child on or you can always make it a Flash webpage.
Build it in Wordpress and use the AnythingSlider plugin to have the pages shift within the main page. This way you can have tabbed navigation and never leave the actual page. No need to write too much code. The AnythingSlider uses html for the slides.
You can also not use wordpress and just use the AnythingSlider code.

Overlay a frame on every webpage a visitor visits?

So I want to be able to have a space that overlays content on any website with the click of a button (something that also is above everything on a web page). An example would be the Google Translate page, http://translate.google.com/translate?u=about%3Ablank&hl=en&langpair=auto|en&tbb=1&ie=UTF-8 where the frame at the top will overlay any website that is entered in the url box.
What I want to do is have a box like this overlay every webpage, like google's translate does, but have it hide with a click of a floating image, say an arrow.
The files will be locally stored on my HDD, but I don't see this being an issue.
I don't know what languages to code this in, but I assume Javascript, however, I do not know the classes to call to do this. Any advice chaps? I'm not asking for a hand out, just a point in the right direction!
It looks like you want to develop a browser extension. Look here for Chrome:
http://code.google.com/chrome/extensions/getstarted.html
There are similar ways to do it for IE, FireFox, and Safari.
It sounds like you'll either need to use frames or an iframe. They are very similar in how you interact with them (say to make them load a new page) although they are different in their implementation.
A great site for learning about frames is w3Schools:
http://w3schools.com/html/html_frames.asp
http://w3schools.com/html/html_iframe.asp
You can use JavaScript to reference the frames via its name or its ID. Ex: document.framename.src = 'hello.php' or document.getElementById('frameId').src = 'hello.php'.
One problem with using frames is that search engines don't like them. If you are using an iframe, the search engine will search your page, but still not the iframe.
As for resizing/hiding the frame/iframe, you can do that with both frames and an iframe, although the method for accomplishing it varies depending on what you use.

Do links with javascript slow down a page?

Due to an issue that came up with a website I have to use javascript for all of the links on the page.
like so...
<img src="image.png"/>
Will having many links with javascript on the webpage slow it down significantly?
Does the Javascript run when the page initially loads or only when a link is clicked?
EDIT: For those asking why I'm doing this. I'm creating an iPad site, when you use the 'add to home page' button to add the site as an icon, it allows users to view the site with no address bar.
However everytime a link is clicked it reopens Safari in a new window with the address bar back.
The only solution I could find was using javascript instead of an html based link to open the page.
For further reference see...
iPad WebApp Full Screen in Safari
2nd answer
"It only opens the first (bookmarked) page full screen. Any next page will be opened WITH the address bar visible again. Whatever meta tag you put into your page header..."
3rd answer down
"If you want to stay in a browser without launching a new window use this HTML code:
a href="javascript:this.location = 'index.php?page=1'"
"
I can see this adding to the bandwidth needs of a site marginally (very marginally), but the render time and the response time on clicking shouldn't be noticeable.
If it is a large concern I would recommend benchmarking the two different approaches to compare the real impact.
What do you mean by slow it down?
Page load time? Depends on the number of links on your page. It would have to be a LOT to be noticeable. Execution time? Again, not noticeable.
The better question to ask is are you o.k. with effectively deleting your website for those without javascript?
Also, if you are worried about SEO, you will need to take additional measures to ensure your site can still be indexed. (I doubt Google follows those kinds of URLs... could be wrong I guess).
EDIT: Now that you explained your situation above, you could easily just "hide" the address bar. See this SO question.

Invoke a Link in custom size browser

I want to have a link or something which could be inserted in an email/forum etc. It's a typical url. But I would like that link to be opened in a custom sized new browser window ( say 800 x 600 ) . It sounds weird, but that is the requirement. Can it be achieved somehow?
Thanks
In an email?
You can't. Email clients insane enough to execute JavaScript are all by unheard of.
In a forum?
Assuming you aren't the administrator of it, you can't. Forums insane enough to encourage XSS attacks are, again, all but unheard of.
Ok. This is how we could kinda achieve this. Let that link be a normal link. It would contain the custom code to create a desired popup on invocation. But the issue is popup blocker in browser. But they somehow liked it.So basically a page opens up which launches the popup without user interference.
