    var timer1 = setTimeout(function() { removeStatusIndicator(); }, statusTimeout);

    clearTimeout(timer1)



The `window.clearTimeout()` should do what you are trying to achieve. 

What is the difference between the following set of pointers? When do you use each pointer in production code, if at all?

Examples would be appreciated!

 1. `scoped_ptr`

 2. `shared_ptr`

 3. `weak_ptr`

 4. `intrusive_ptr`

Do you use boost in production code?

I have seen:

  - `http://www...`
  - `ftp://blah.blah...`
  - `file://blah.blah...`
  - `unreal://blah.blah...`
  - `mailto://blah.blah...`

What is that first section where you see `http` and the like called?

Can I register my own?

I have a few places where I use the line below to clear out a status, for example.  I have a few of these that hang out for 10 seconds or more and if the user gets clicking around the action can occur at incorrect time intervals.

    window.setTimeout(function() { removeStatusIndicator(); }, statusTimeout);

Is it possible to cancel or kill this with some jQuery or JavaScript code, so I don&#39;t have this process hanging around?


Cancel/kill window.setTimeout() before it happens

I have a few places where I use the line below to clear out a status, for example. I have a few of these that hang out for 10 seconds or more and if the user gets clicking around the action can occur at incorrect time intervals.
<pre><code class="hljs language-javascript">window.setTimeout(function() { removeStatusIndicator(); }, statusTimeout);
</code></pre>

There was [another thread about this](https://stackoverflow.com/questions/7477/autosizing-textarea), which I&#39;ve tried. But there is one problem: the `textarea` doesn&#39;t shrink if you delete the content. I can&#39;t find any way to shrink it to the correct size - the `clientHeight` value comes back as the full size of the `textarea`, not its contents.

The code from that page is below:

    function FitToContent(id, maxHeight)
    {
       var text = id &amp;&amp; id.style ? id : document.getElementById(id);
       if ( !text )
          return;
    
       var adjustedHeight = text.clientHeight;
       if ( !maxHeight || maxHeight &gt; adjustedHeight )
       {
          adjustedHeight = Math.max(text.scrollHeight, adjustedHeight);
          if ( maxHeight )
             adjustedHeight = Math.min(maxHeight, adjustedHeight);
          if ( adjustedHeight &gt; text.clientHeight )
             text.style.height = adjustedHeight + &quot;px&quot;;
       }
    }

    window.onload = function() {
        document.getElementById(&quot;ta&quot;).onkeyup = function() {
          FitToContent( this, 500 )
        };
    }

Which is the right thing to do?

    if (myObj[&#39;key&#39;] == undefined)

or

    if (myObj[&#39;key&#39;] == null)

or

    if (myObj[&#39;key&#39;])

What is the best way(s) to fake function overloading in Javascript? 

I know it is not possible to overload functions in Javascript as in other languages. 
If I needed a function with two uses `foo(x)` and `foo(x,y,z)` which is the best / preferred way:

 1. Using different names in the first place
 2. Using optional arguments like `y = y || &#39;default&#39;`
 3. Using number of arguments
 4. Checking types of arguments
 5. Or how?

Actually I am trying to move some box alternatively with in another box. I made it work, but both the blocks do not interrupt each other. What should I do? How can I make the blocks cross each other? I try using style:position, but it is not working.

Here is the code I have been using:

    &lt;marquee direction=&quot;down&quot; behavior=&quot;alternate&quot; scrollAmount=10 style=&quot;border:2px solid blue;&quot;&gt;
      &lt;marquee behavior=&quot;alternate&quot; scrollAmount=50 &gt;
        &lt;img src=&quot;img1.JPG&quot;&gt;
      &lt;/marquee&gt;
      &lt;marquee behavior=&quot;alternate&quot; scrollAmount=10 &gt;
        &lt;img src=&quot;img1.JPG&quot;&gt;
      &lt;/marquee&gt;
    &lt;/marquee&gt;

What am I doing wrong?


Nested and multiple &lt;marquee&gt; troubles

I have an HTML table with several columns and I need to implement a column chooser using jQuery.  When a user clicks on a checkbox I want to hide/show the corresponding column in the table.  I would like to do this without attaching a class to every td in the table, is there a way to select an entire column using jQuery?  Below is an example of the HTML.

    &lt;table&gt;
    	&lt;thead&gt;
    		&lt;tr&gt;&lt;th class=&quot;col1&quot;&gt;Header 1&lt;/th&gt;&lt;th class=&quot;col2&quot;&gt;Header 2&lt;/th&gt;&lt;th class=&quot;col3&quot;&gt;Header 3&lt;/th&gt;&lt;/tr&gt;
    	&lt;/thead&gt;
        &lt;tr&gt;&lt;td&gt;Column1&lt;/td&gt;&lt;td&gt;Column2&lt;/td&gt;&lt;td&gt;Column3&lt;/td&gt;&lt;/tr&gt;
        &lt;tr&gt;&lt;td&gt;Column1&lt;/td&gt;&lt;td&gt;Column2&lt;/td&gt;&lt;td&gt;Column3&lt;/td&gt;&lt;/tr&gt;
    	&lt;tr&gt;&lt;td&gt;Column1&lt;/td&gt;&lt;td&gt;Column2&lt;/td&gt;&lt;td&gt;Column3&lt;/td&gt;&lt;/tr&gt;
    	&lt;tr&gt;&lt;td&gt;Column1&lt;/td&gt;&lt;td&gt;Column2&lt;/td&gt;&lt;td&gt;Column3&lt;/td&gt;&lt;/tr&gt;
    &lt;/table&gt;
    
    &lt;form&gt;
    	&lt;input type=&quot;checkbox&quot; name=&quot;col1&quot; checked=&quot;checked&quot; /&gt; Hide/Show Column 1 &lt;br /&gt;
    	&lt;input type=&quot;checkbox&quot; name=&quot;col2&quot; checked=&quot;checked&quot; /&gt; Hide/Show Column 2 &lt;br /&gt;
    	&lt;input type=&quot;checkbox&quot; name=&quot;col3&quot; checked=&quot;checked&quot; /&gt; Hide/Show Column 3 &lt;br /&gt;
    &lt;/form&gt;

&lt;!-- End of automatically inserted text --&gt;

I am getting a bit tired of looking at unformatted json blobs in FireBug. 

Does anyone know an equivalent to PHP&#39;s print_r() for jQuery?


Something that would recursively make a display string from an object or array, that I could display on the page for quick debugging?

Thanks!

jQuery: print_r() display equivalent?

I have a simple html block like:

    &lt;span id=&quot;replies&quot;&gt;8&lt;/span&gt;

Using jquery I&#39;m trying to add a 1 to the value (8).

    var currentValue = $(&quot;#replies&quot;).text();
    var newValue = currentValue + 1;
    $(&quot;replies&quot;).text(newValue);

What&#39;s happening is it is appearing like:

81

then

811

not 9, which would be the correct answer.  What am I doing wrong?

I&#39;m trying to add a row to a table and have that row slide into view, however the slidedown function seems to be adding a display:block style to the table row which messes up the layout.

Any ideas how to work around this?

Here&#39;s the code:

    $.get(&#39;/some_url&#39;, 
      { &#39;val1&#39;: id },
    
      function (data) {
        var row = $(&#39;#detailed_edit_row&#39;);
        row.hide();
        row.html(data);
        row.slideDown(1000);
      }
    );
