What is DOM element?
I'm learning HTML and CSS and are now trying to learn JavaScript. Came across something called DOM.
I don't really get when the DOM are created. And I don't really get where it is located?
Is it some sort of file? Where can I find it and how can I view it.
Is it created automatically when save my index.html
The Document Object Model (DOM) is just the way your browser internally represents the HTML. It is a perfect tree-structure, which makes it very easy to visualize/manipulate.
The easiest way to see it is probably in the developer tools of your browser. For example in Chrome, press ctrl-shift-I (or F12) to open the developer tools. Then you can find the DOM in the Elements tab.

Linking to a specific (non-function's) documentation page programmatically
(1 answer)
Closed 6 years ago.
I want to open a specific help page in Matlab's offline documentation browser programmatically, for example the DAQ Properties.
This would be the page in the online help:
https://de.mathworks.com/help/daq/propertylist.html
I only know how to open specific pages like this:
doc('daq/NotifyWhenDataAvailableExceeds')
Is there a way to open the Property List directly programmatically in the offline documentation browser?
Answer from Matlab Technical Support:
To view the installed version of the page in the Help browser, run
this command:
web(fullfile(docroot, 'daq/propertylist.html?s_cid=doc_ftr'))

Smart Gwt components are not rendered in html div tag
My problem is that I had a project which was running gwt widgets nicely. Now for some client requirements, we introduced some smartGwt changes in it.
The problem is that all those requirements have been done successfully, but as a result or something, the previous ComboBox dropdown isn't working, none of them. Please help.
Do I have to post the code also (because its too large)? If you want it, I will try to paste it here.
Thanks in advance.
What do you mean by "isn't working". There are zindex issues when you use Gwt and Smartgwt side by side. You can have a look at this thread ( here)if it's this sort of problem. If not give us more details.

Can anybody help me that how can i set PRINT and save as PDF icon(functionality) in TYPO3 pages ?
Thanks...in advance..
There are many examples in Google and I think that you should browse them, to find the one the best fits your needs.
In general 'historically' print version was suggested to be build with new PAGE cObject which typeNum is set to 98 (of course that's only suggestion) in general going this clue, you should find many examples and other resources by searching in Google for typo3 typeNum 98.
When you'll create alternative PAGE object (and maybe also use modified template for it) you need also add on your webpage a link which be the same as the current URL but with additional param &type=98, when user will click it TYPO3 will open the alternative version of the page. So you can add to this a JS in header which will also start system's print dialog.
You can also search the extensions repository and find something for placing the print button if you are unfamiliar with TypoScript.
PDF rendering is similar from point of view of the frontend, however most probably you need to use some additional lib, so it will be best to search for ready to use solution from the repo.
In general PDF version could be tricky, therefore from my experience I can say that nowadays it's sometimes better to avoid the PDF icon at all or use linking to some external service. Of course all depends on your needs. Remember that there are many programs which are able to create PDF's so if it is not required maybe it's no worth of its effort.
Finally take a look at the AddThis widget it can be also used for easy adding of icons for printing and online PDF creation, additionally you can also send invitations via e-mail, or even share the link on the hundreds social portals. And what's most important installing this is just like adding view lines of HTML code vie TypoScript.

GWT: How to create a new page
i'm new to GWT. I want to know, how to navigate from one page to another one?
In my application, in the home screen, after enter the username, password. If the username, password matches. A new page should open to display the contents. I'm using the MVP Architecture.
In GWT application navigation is different from a classic webapp model. GWT is an asynchronous framework, you rather switch content of your page and manage the History by built in tools rather that opening new webpages. Plese refer to Expenses sample located inside GWT SDK or try to use Spring ROO to scaffold your app using MVP.
Expenses in particular uses custom sliding panel to switch contents between for instance Details View and list view of all expenses.
If you really need to move to a new page, please see this solution.
I think your best bet is to study Activities and Places. Work through the documentation and the examples. When you figure it out, you'll realize that it gives you the page-to-page experience that a user expects from a website, including navigation via history, bookmarks, and the Back button, but in an MVP achitecture (also built into Activities and Places via the ActivityManager) and within a single actual page with GWT swapping in and out the contents (as per the answer from VoodoRider).

How to enable iOS 5 Safari Reader on my website?
So iOS 5 Mobile Safari has this new reader feature but I don't understand how it works on my website and what I as a web developer can do to make sure a webpage is "Reader" compatible.
Does anyone know where I can find docs on this, I understand it's still in beta but there should still be docs somewhere. As far as I can tell by playing with it, its seems to be looking for RSS feeds? Can anyone elaborate?
There isn't really official documentation for it, but you just have to keep a good structure in your HTML. I've found some 3th party documentation here:
http://mathiasbynens.be/notes/safari-reader
For example, make use of heading tags for titles.
<h2>This is one item</h2>
You should then either use a DIV or SPAN to wrap your content in.
<span>This is the content that you would see in the reader</span>
What also seems to help is to use class names like "author", "content" or "article" for your content. It will be picked up by the reader. So you would get a result like this:
<h2>My Item</h2>
<span class="author">Some Name</span>
<span class="article">My content.</span>
I've seen websites without RSS feeds and still have the reader option, so that's not necessary.
