3,599,754 | 3,599,755 | Launch Event Only Once Every 60 Seconds (JavaScript) | <p>I have a video that is 60 seconds long. I am working on adding some JavaScript to send data from my video player to Google Analytics. What I am looking to do is to launch an event no more than once every 60 seconds for a range of time.</p>
<p>So for example, a user watches 21 to 40 seconds into a video, I want only one event launched (rather then 19 times for the 19 seconds of time). Then the user watches 41 to 60 seconds into the video, I want only one event launched. I actually have figured this part out already.</p>
<p><strong>The problem is when it comes to time.</strong> So if a user watches the 21 to 40 seconds it launches an event. They watch the rest of the video and mentally process it and decide "hey I want to watch the video again". If they watch the video again, that one event at 21 to 40 seconds won't launch again unless they refresh the page.</p>
<p>How can I edit my script so an event is launched only once every 60 seconds for a specific range?</p>
<pre><code><script type="text/javascript">
function Follow( minimum, maximum )
{
this.min = minimum;
this.max = maximum;
this.done = false;
}
var following = [
new Follow( 1, 20 ),
new Follow( 21, 40 ),
new Follow( 41, 60 )
];
player().Time(
function(event)
{
var gone = Number(event.secondspassed);
for ( var t = 0; t < following.length; ++t )
{
var Follow = following[t];
if ( gone >= Follow.min && gone < Follow.max )
{
if ( ! Follow.done )
{
var range = Follow.min + " Seconds Watched ";
_gaq.push(['_trackEvent', range, 'Play', 'Title']);
Follow.done = true;
}
break;
}
}
}
);

<p>so that the following would produce a single alert with the text "in your face"</p>
<pre><code>if (new MyCustomBoolean('TRUE')){
alert("In your face!");
}
if (new MyCustomBoolean('FALSE')){
alert("not so much.");

<p>Now i can work around this by explicitly calling the valueOf function or. by checking equivalence through "myBObj == true".</p>
<p>So is it possible to have a custom boolean object that inherits from Boolean.prototype such that i could write if blocks as described above?</p>

<p>It is working fine as I have it now. </p>
<p>I want to add some functionality. After the form submits the plugin is returning back responseText (see above link). I am updating one div with this link. What If I want to update multiple div's...with different messages. Basically, I'm wondering if there is a way to get 'multiple' responseText(s). </p>
<p>A way around is to put all I want in one responseText and then somehow break it (using substring) and update multiple divs?</p>
<p>Also, How do we add some content to the div using jQuery?</p>

2,335,468 | 2,335,469 | How many times is onDraw() called? | <p>I'm just starting to play around with the android SDK, and was trying to build a simple bubble wrap app, so I could understand how custom components work. I have my onMeasure(), onSizeChanged(), onDraw() methods which create the unpopped bubble bitmaps. I have a onTouchEvent() so I know which bubble number is being touched. After this I wanted to replace the unpopped bubble with a popped bubble image, and was wondering how I could go about doing that. If I understand it right, onDraw() is only called once initially right? </p>
<p>Thanks in advance!</p>

<p>SlidingDrawer has the behavior I want, but doesn't seem to have a way of controlling how much it's open or closed (perhaps I'm just missing it). </p>

2,100,527 | 2,100,528 | Choosing the type of Index Variables | <p>We use Integer type represent index variables most of the time. But in some situations, we're forced to choose </p>

<p>This will cause the compiler to raise the warning that mixed use of signed/unsigned variables. if I make the index variable as <code>for( size_t i = 0; i < vec.size(); i++ )</code>, (or an <code>unsigned int</code> )it will sort out the issues.</p>
<p>When it come more specific to use windows types, most of the Windows APIs are dealing with DWORD (which typedef-ed as unsigned long).</p>
<p>So when I use similar iteration, will again cause the same warning. Now if I rewrite it as </p>
<pre><code>DWORD dwCount;
....
for(DWORD i = 0; i < dwCount; ++i)
....
</code></pre>
<p>I find this a bit weird. It might be the problem withe perceptions. </p>
<p>I agree that we are supposed to use the same type of index variable to avoid the range problems can happen with the index variables. For e.g if we're using </p>
<pre><code>_int64 i64Count; //
....
for(_int64 i = 0; i < i64Count; ++i)

I also want to call the the same function when the select box is first loaded. I use jQuery .load, but the ajax function is called before any of the options are loaded and the input to my ajax function is undefined. Does anyone know how to get jQuery to wait for all the options to load before calling the function?</p>
<p>Thanks.</p>
<p><strong>Edit - Adding Code</strong>
I have found that a <code>setTimeout()</code> works pretty well to delay the function. However, I get nervous using <code>setTimeout()</code> because if the page loads slower than usual, it won't work. I tried replacing the timeout with <code>$(document).ready</code> as you suggested, but the function was still called before an option was selected and the input was undefined. </p>
<p>Here's the code:</p>
<pre><code><script type="text/JavaScript">
setTimeout('AjaxFunction($("#SelectID option:selected").val()));', 400);
</script>
<select id="SelectID" name="SelectName" onchange="AjaxFunction(this.value);">
<option value='Inland Empire'>Inland Empire</option>
<option value='San Bernardino'>San Bernardino</option>
<option value='Riverside'>Riverside</option>
<option value='California'>California</option>

<p>In my view one of the benefits of using <code>listStr.isEmpty</code> is that it does'nt check the size of the list and then comapre it to zero, it just checks if the list is empty. Are there any other advantages as I often see <code>if(listStr.size == 0)</code> instead of <code>if(listStr.isEmpty())</code> in codebases. Maybe there is a reason its checked this way that I am not aware of ?</p>

898,253 | 898,254 | smart pointers and when they destruct the object they point to | <p>I wish to use a smart pointer to an object that will be accessed by quite a few different objects. Therefore i don't want to destruct it until all the pointers are released to it. The smart pointer will point to an object that instantiates a couple objects, which instantiate a couple objects, and so on, so that you can access all the individual System objects through this one pointer. However, let's say that i create the smart pointer in main as <code>std::shared_ptr<System> object(new System);</code> and then let's say i have another object that all other entities derive from which has a static std::shared_ptr that i set equal to object above. The static declaration means that it's managed by the compiler and not on a per instance basis. So let's say that all the objects that derive from the base class use this static pointer to access the System object. WHEN is this smart pointer destructed if ever? I need this pointer to be destructed before the one in main, who's destruction should drop the reference count to 0, destroying the object pointed to by it. So my question is, when is a statically declared std::shared_ptr destructed in the scheme of things. Or even if a pointer were declared globally and used all over, when would this object be destructed?</p>
<p>the base class would look something like this:</p>
<pre><code>class Base
{
public:
static shared_ptr<System> m_System;
};
int main()
{
std::shared_ptr<System> system(new System);
Base::m_System = system;
/*
other stuff
*/
return 0;
}
</code></pre>
<p>also another thing that someone could help me with, i'm not very good with const-ness, and i would like for that static pointer to be a constant that cannot be changed by the derived classes. But then if it's const i can't initialize it like i did in main, right? so how would i go about declaring it so that it is const, but i can still set it equal to a pointer initially like this.</p>
