I'm using titanium webviews to open an internal html page that I need to internationalize. This seems a rather basic need, but I can't seem to find the right documentation on how to accomplish it. This guide (https://wiki.appcelerator.org/display/guides2/Internationalization) points out how to use internationalization from app.js, but as I need to have it in my html I was wondering on the best way to do it. I was thinking on grabbing the onload event and populate the html with translated strings, but then, how do I obtain the html elements that should be translated? From my investigations it seems that I cannot use jQuery dom manipulation from within app.js..
Any help?

I am going to show a mobile version of wikipedia page in my app.
The easiest way is to use UIWebView to show mobile view page, e.g. https://en.m.wikipedia.org/w/index.php?title=White_House
However I want to make certain changes to the page:
Remove the search bar.
remove all external links in the page.
while keep all format/image/layout unchanged.
I did some search. Seems I have to retrieve all contents in json with wikipedia API and reformat everything by myself.
Any easier way?
You can load the HTML, make "Find and replace" and remove whatever you want. (Modify the HTML itself.
After that you can load the HTML into the UIWebView.
Note: This might break when wikipedia will change it's webpage structure...
I'm new to rails and could use some help choosing the right rich text editor. I would like visitors to be able to add content (text, images, and video) to the site using one rich text editor form. Once submitted by the visitor I need to be able to sanitize content, save images/video to public folder, and save text and the path to those images/videos to the database for future retrieval. Is there a gem or combination of gems that can help me accomplish this.
I've already looked into tinymce, ckeditor, and mercury but none seems to meet my needs. Tinymce and ckeditor and their plugins require the URL of the image which means that users would first have to upload the image and then know the path to it. That's a little to complicated for my audience. Mercury is based in html5 and is currently unstable depending on the browser. Are there any other options out there?

I didn't look to deeply, but I'm assuming one of these jquery/javascript plugins is a WYSIWYG HTML editor.
Once you've got a good client side HTML editor running, the next part is parsing the HTML when sent to the rails app.
http://www.rubyinside.com/nokogiri-ruby-html-parser-and-xml-parser-1288.html
I've never used Nokogiri, but it's name is very familiar, It seems to be used a lot.
Sanitization is baked into Rails. The default sanitize will strip out ANY HTML, but you can call sanitize telling it which HTML elements NOT to block. Assuming you parse out the HTML you allow to pass through sanitize, using Nokogiri (or whatever HTNL parser you find), you'd be manually santitizing those elements as you extract values from them.
The tricky part would be eliminating the 'file select' operation on the client side as the user needs to select a local image to place in the HTML document. I don't think you can eliminate it, but hopefully HTML editor makes it as simple as possible. There not really much you can do about it, if the user will add one of HIS images to an HTML document he'll upload, he'll HAVE to select it at some point.
This is the closest I've come to something that you describe, I'm also looking for something similar so I'll keep you posted :)

How can I stop search engines indexing part of my page? Is there an HTML5 element for this?
Its just a line of text that I want to hide (a co-worker doesnt want their name on google for some reason). Im thinking that I could inject the text with javascript, but I have heard google does sometimes look inside javascript files.
I also thought of using images instead of text, but im concerned how this will look cross device and platform. Ive noted text rendering can differ on mac and pc and thats before ive had to think about mobile devices, retina displays, etc.
Thanks
You can't hide content unless you use the methods you've already outlined above. Your best bet is to use JavaScript in an external file and then block that file using robots.txt.
Is it possible to create HTML lists such as ordered and unordered lists without using UIWebView?
Thanks
You need a UIWebView to display/interpret html, unless of course you want to write your own implementation to parse html and display it (but why would you?). If on the other hand you are just trying to display lists without needing html, you can use a UITableView.
I've not written an iOS app and want to know if what I want to do is reasonably easy before I invest all my time in it. The idea is simply to leverage the built-in webkit methods to write my own browser. I've seen tutorials where this is done fairly easily. However, the twist is I want to apply some rewrite/regex rules prior to the page rendering. ie, you load http://example.com which is a page containing the word 'foo'. Prior to displaying the page, the app rewrites 'foo' to 'bar' and renders.
Is this possibly to do easily without actually writing a ground-up browser?
Thanks!
It's doable (assuming you're using the standard UIWebView component to render the page), and there are a few ways you could go about it. Among them:
You could download the HTML and parse it via Objective-C string handlers before loading it into the UIWebView
You coud use load the HTML as-is and use the UIWebview's stringByEvaluatingJavaScriptFromString: message to "inject" javascript onto the page, manipulating the DOM itself
You could go the Opera route, and pre-render the page via a server-side proxy before downloading it to the client.
How far down the rabbit hole you want to go would be up to you, of course. Easy is in the eye of the beholder.
