<p>Is there a way to make native function chainable?</p>
<p>For example, I want to do this:</p>
<pre><code>var ele = document
.createElement("div")
.setAttribute("id", "foo")
.focus();
</code></pre>
<p>instead of this:</p>
<pre><code>var ele = document.createElement("div");
ele.setAttribute("id", "foo");
ele.focus();

<p>Is there a way to do that? If it is possible, then it will definitely save me a lot of typing works.</p>

<p>So my question is, is there a tool that records how the JS performs on a website? For example, I am working on a plugin and I am making various changes, but I need some feedback in order to decide if I am actually making optimizations or not. A simple monitoring of the time it takes to execute the JS file would be perfect.</p>
<p>So anyone know such a tool?</p>

<p>A coworker recently checked in a change to a file that added:</p>
<pre><code>ini_set('max_execution_time', 0);
</code></pre>
<p>The default value had been too low for a page that did some complex processing before returning the output to the user.</p>
<p>The manual states that the main purpose of the setting is to:</p>
<blockquote>
<p>prevent poorly written scripts from tying up the server.</p>
</blockquote>
<p>But also goes on to state:</p>
<blockquote>
<p>Your web server can have other timeout configurations that may also interrupt PHP execution. Apache has a <em>Timeout</em> directive and IIS has a CGI timeout function. Both default to 300 seconds. See your web server documentation for specific details.</p>
</blockquote>
<p>We're running under Apache, so that <em>Timeout</em> setting applies. Is there any reason not to set <code>max_execution_time</code> to zero globally? I'm mainly curious as to whether there are benefits I'm overlooking when <strong>not</strong> setting it to zero.</p>

1,736,049 | 1,736,050 | Returning a flexible datatype from a C++ function | <p>I'm developing for a legacy C++ application which uses ODBC for it's data access. Coming from a C# background, I really miss the ADO style of data access.</p>
<p>I'm writing a wrapper (because we can't actually use ADO) to make our data access less painful. This means no <code>char</code> arrays, no manual text blob streaming, and no declaritive column binding.</p>
<p>I'm struggling with how to store / return data values. In C# at least, you can declare an <code>object</code> and cast it to whatever (as long as the type is convertable).</p>
<p>My current C++ solution is to use <code>boost::any</code> to store the data value in a custom <code>DataColumnValue</code> object. This class has conversion and assignment operators to the various types used in our app (more than 10). There's a bit of complexity here because if you store an <code>int</code> in the <code>boost::any</code> and try to <code>boost::any_cast<long></code> you get a <code>boost::bad_any_cast</code>. Client objects shouldn't have to know how the value is stored internally.</p>
<p>Does anyone have any experience trying to store / return values whose types are only known at runtime? Is there a better / cleaner way?</p>

<p>However, I also have a menu on the left, and because the links (left justified) are of differing length, the best I can do is adjust the padding to ease the text a uniform amount between links. Therefore, long link text goes to the right edge of the container, buy short text only makes it about half way.</p>
<p>In reading about this, I have learned that you can not modify the text align property as it is non numeric. Is there any other way to do this?</p>
<p>I of course tried to go with:</p>
<pre><code>$('#selector').css('text-align':'right')

<p>So, it means that It cannot order collection of Products. It needs some kind of subquery, but I'm not sure what exactly does it need.</p>

I am able to launch the application by making a link to "myapp://act/launch" from my phone web pages. This works only if my application is installed on the device.
What I want to do is detect if the URI Scheme is supported from the browser and then prompt my own message saying "please download the app etc..." if the handler for the URI scheme is not found.</p>
<p>Is there a way I can detect or find the list of URL Scheme handlers on the Phone from the Web Browser ?</p>

1,496,312 | 1,496,313 | Is it possible to use too many functions in Python? | <p>This kind of a broad question.</p>
<p>As I find myself having to write longer and longer scripts, I find that my instinct is to break everything up into bite-sized functions; however, this ultimately results in functions calling functions calling functions calling functions.... and I'm wondering if I'm completely thinking about this the wrong way.</p>
<p>Here's what an abridged script might look like. Sorry it's kind of contrived.</p>
<pre><code>def simple_task_1():
return
def simple_task_2():
return
def simple_task_3():
return
def simple_task_4():
return
def complex_task_1():
simple_task_2()
simple_task_3()
simple_task_4()
return
def startup():
simple_task_1()
complex_task_1()
simple_task_4()
def finish():
# other function calls
return
def main():
startup()
finish()
</code></pre>
<p>So, is this the correct way to be using functions? Is there an objective point where you can say you've made too many function calls inside each other? Should I even be making functions for tasks that only end up being done once?</p>

1,973,367 | 1,973,368 | finding the centre of dynamically generated divs | <p>I have a page that contain n amount of divs in columns of 3. The divs are potentially different widths, and some divs will contain one image, whereas some will contain two. Image number one is always centred in the div. Unfortunately, the way the page is generated it's impossible to have image number 2 sit a certain and consistent distance from image number one - which is what I'm trying to achieve.</p>
<p>Each image number 2 has a unique asp.net client Id followed by icon e.g. ctl00_icon.</p>
<p>Each image one has the same name - not my doing!</p>
<p>Non of the divs have an id</p>
<p>So what I thought about doing was - get the width of each div, divide it my 2, and use this to give my image 2 a reference point for positioning.</p>
<p>Any pointers on how I might go about achieving this? Or is there a better way?
