3,696,917 | 3,696,918 | Time to learn JavaScript properly, but how? | <p>Firs off, thanks for reading! A bit of a non-technical query for all you javascripters out there. Here's my situation. I've been in Front-End development now four years full time. But for different reasons javascript hasn't been in the priorities that I've been asked to do. Don't get me wrong I've developed dozens of websites and I've used my own snippets of javaScript and used also many Jquery plugins. But I think it's time to really learn and be able to do something better than the meaningless stuff that I usually do with this great language.</p>
<p>The problem is that I think it's quite overwhelming to study this language properly, I just don't know which approach I should give it. I keep reading books but either I feel that I already know some stuff or I feel completely clueles...</p>
<p>I know you're going to say, stop writing stupid questions and go on cracking them books. You are right but I do think you folks could give me some advice and some tips on how did you manage to master the language, what was that you find the hardest, what would you tell a beginner to focus on... believe me this is useful stuff for me and hopefully it is also for someone else out there.</p>
<p>Thanks a lot folks!</p>

It's simple but I haven't entire wrapped my head around them. Here's one of scenarios that's bewildering to me.</p>
<p>I have two functions <code>mainfunc</code> and <code>wrapperfunc</code> (which is a wrapper function for the main function). It looks like this.</p>

<p>In this method, all three parameters are positional. Since <code>j.doe</code> comes into <code>uname</code>, the other two params can be accessed by <code>*args</code></p>
<p>..but is it possible to pass some of the params to <code>wrapperfunc</code> from a dict so that I can still access <code>uname</code> inside <code>wrapperfunc</code> directly and then pass the remaining positional parameters to the <code>mainfunc</code>. Something like the following snippet:</p>
<pre><code>params = {'uname':'j.doe'}
wrapperfunc(**params, 'john', 'doe')
</code></pre>
<p>I want to access the named parameters directly inside <code>wrapperfunc</code> but pass all the positional parameters to <code>mainfunc</code>.</p>

1,003,942 | 1,003,943 | Still confused about JavaScript Expressions and Statements | <p>I found this PDF <a href="http://www.fbeedle.com/javascript/69-4ch04.pdf" rel="nofollow">here</a> and in it the author describes an expression as any valid set of literals, variables, operators, function calls and expressions that evaluate to a single value i.e.</p>
<pre><code>3 + 7
3 + 7 + 10 + ""
"Dr." + " " + "Pepper"
</code></pre>
<p>That all seems fine to me. An a statement is any set of declarations, method and function calls and expressions that performs some action i.e.</p>
<pre><code>var num = 1
document.write("hello")
</code></pre>
<p>But later on they refer to the last line of the examples below as statements</p>
<pre><code>var salutation = "Greetings, "
var recipient = "Earthlings"
salutation + recipient //statement
var greeting = "Greetings, "
greeting += "Earthlings" //statement
</code></pre>
<p>Why isn't <code>salutation + recipient</code> and <code>greeting += "Earthlings"</code> considered an expression when they are adding two strings like in their expression example <code>"Dr." + " " + "Pepper"</code></p>

<p>It is very simple and straight-forward. It takes <code>href</code>, filters it and should load the content. But it doesn't. jQuery doesn't seem to understand the <code>*</code> wildcard. When I ommit it and put simply <code>href + ' .workdisplay'</code>, it works. But I don't want to have this additional container included. What can I do?</p>

917,397 | 917,398 | maximize window and view size | <p>my activity has a single custom view class and I'd like to make that full screen.
According to other answers I should call </p>
<pre><code>getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
</code></pre>
<p>in Activity.onCreate but it doesn't work for me (at least in the emulator). The default size doesn't change. The only thing that worked so far is </p>
<pre><code>getWindow().setLayout(600, 400);
</code></pre>
<p>or any other fixed values. Calling setLayout with MATCH_PARENT doesn't work either (and I have tried uncounted other ways without success).
So the question is: what is the canonical way to start a maximized activity? (somewhat like full screened in a graceful sense, that is do not hide title bars, status bars and so on).</p>
<p>Thanks in advance
Olaf</p>
<p>Edit 1:</p>
<p>This is the relevant part:</p>
<pre><code>public void onCreate(Bundle b) {
super.onCreate(b);
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(
WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
tableView = new DrawView(this);
setContentView(tableView);
}
</code></pre>
<p>I readded the FEATURE_NO_TITLE flag in the above snippet
because I didn't know that in the android world this is
considered the default (but it is completely OK for me).
DrawView is a direct subclass of View and does not
override onMeasure. Also there is no layout.xml.
The effect is an (expected invisible) window,
which is far to small (or at least the contained DrawView is).
I tried with XOOM and Galaxy skins.</p>
<p>Update 2:
The issue seems not to be in the source code. I tried BitmapPixels
from the ApiDeoms and it worked as expected (full sized window). Then I copied the source code (just one file) in a new fresh project and suddenly I got the same results: the app covers only a small portion of the screen (and one bitmap gets clipped).
I guess it has something to do with the parent activity. but I can't find any differences between the project properties of APIDemos and my test project.</p>
