I had the same problem and it was driving me mad!!!!

Until I found that I was loading bootstrap before jqueryui...

I switched the order and notice that if I **load jqueryui BEFORE bootstrap**, I have no such problem :)



THis issue is due to jquery-ui blocking the initialization of Button definitions from bootstrap for users like me who have problems with shifting the order of the javascript file calls for instance when using the **CJUiAutocomplete widget in Yii**, **just shift the javascript corresponding to button.js  from the bootstrap file to the main working file and it will work smoothly.**

**Alternatively take the corresponding js and place it in a separate file that is called at the bottom of your javascript file stack.**

Swapping the load order of Bootstrap and jQueryUI solves this problem but then it causes other issues like the Close X on jQueryUI dialogs fails to display.  Is there another way to resolve this?


In fork child, if we modify a global variable, it will not get changed in the main program.

Is there a way to change a global variable in child fork?

    #include &lt;stdio.h&gt;
    #include &lt;stdlib.h&gt;
    #include &lt;unistd.h&gt;
    
    int glob_var;
    
    main (int ac, char **av)
    {
      int pid;
    
      glob_var = 1;
    
      if ((pid = fork()) == 0) {
        /* child */
        glob_var = 5;
      }
      else {
        /* Error */
        perror (&quot;fork&quot;);
        exit (1);
      }
    
      int status;
      while (wait(&amp;status) != pid) {
      }
       printf(&quot;%d\n&quot;,glob_var); // this will display 1 and not 5.
    }

I read this:
[http://en.wikipedia.org/wiki/A*_search_algorithm][1]

It says A* is faster than using dijkstra and uses best-first-search to speed things up.

If I need the algorithm to run in milliseconds, when does A* become the most prominent choice.

From what I understand it does not necessarily return the best results.

If I need quick results, is it better to pre-compute the paths? It may take megabytes of space to store them.

I&#39;m trying to turn some regular buttons in radio buttons the twitter bootstrap way ([http://twitter.github.com/bootstrap/javascript.html#buttons][1]).

I followed the instructions, but when I press the buttons I get the following error in the console:

**Uncaught Error: cannot call methods on button prior to initialization; attempted to call method &#39;toggle&#39;** .

Do you know what might cause it? The buttons are loaded in the page and only become visible when the corresponding content is displayed by AJAX.

Thanks!

Bootstrap radio-buttons toggle issue

I&#39;m trying to programmatically clear a drop down using the fantastic [Select2][1] library. The drop down is dynamically filled with a remote ajax call using the Select2 `query` option.

HTML:

    &lt;input id=&quot;remote&quot; type=&quot;hidden&quot; data-placeholder=&quot;Choose Something&quot; /&gt;

Javascript:

            var $remote = $(&#39;#remote&#39;);

            $remote.select2({
                allowClear: true,
                minimumInputLength: 2,
                query: function(options){
                    $.ajax({
                        dataType: &#39;json&#39;,
                        url: myURL + options.term,
                        error: function(jqXHR, textStatus, errorThrown){
                            smoke.alert(textStatus + &quot;: server returned error on parsing arguments starting with &quot; + options.term);
                        },
                        success: function(data, textStatus, jqXHR){
                            var results = [];
                            for(var i = 0; i &lt; data.length; ++i){
                                results.push({id: data[i].id, text: data[i].name});
                            }

                            options.callback({results: results, more: false});
                        }
                    });
                }
            });
            
Unfortunately, the call to `$remove.select2(&#39;val&#39;, &#39;&#39;)` throws the following exception:

     Uncaught Error: cannot call val() if initSelection() is not defined

I&#39;ve tried setting the `attr`, setting the `val`, `text` and the Select2 specific `data` function. Can&#39;t seem to make the guy clear and work in a radio button like manner. Anyone got suggestions?

Clear dropdown using jQuery Select2

I&#39;m using D3 to generate a bar chart (I adapted the code from [this example](http://bl.ocks.org/3885304)). The labels I&#39;m using on the *x*-axis are a couple of words long each, and since this makes all of the labels overlap I need to break these labels across lines. (It&#39;ll be fine if I can replace all of the spaces in each label with newlines.)

I originally tried this by replacing the spaces with literal newlines (`&amp;#xA;`) and setting `xml:space=&quot;preserve&quot;` on the labels&#39; `&lt;text&gt;` elements. Unfortunately, it turns out that SVG doesn&#39;t respect this property. Next I tried to wrap each word in a `&lt;tspan&gt;` that I could later style. I passed each label through this function:

    function (text) {
        return &#39;&lt;tspan&gt;&#39; + text.replace(/ /g, &#39;&lt;/tspan&gt;&lt;tspan&gt;&#39;) + &#39;&lt;/tspan&gt;&#39;;
    }

but this just puts literal `&lt;tspan&gt;`s into the output. How can I wrap my text labels in `tspan`s (or do something else) so that my labels don&#39;t overlap?

How do I include newlines in labels in D3 charts?

Now this isn&#39;t just another *What&#39;s the difference question*, I have [done some tests(http://jsfiddle.net/ZC3Lf/)][1] modifying the `prop` and `attr` of `&lt;form action=&quot;/test/&quot;&gt;&lt;/form&gt;​`  with the output being:

&gt; **1) prop Modification test**  
&gt; Prop: `http://fiddle.jshell.net/test/1`  
&gt; Attr: `http://fiddle.jshell.net/test/1`  
&gt;
&gt; **2) Attr Modification test**  
&gt; Prop: `http://fiddle.jshell.net/test/1`  
&gt; Attr: `/test/1`  
&gt; 
&gt; **3) Attr then Prop Modification test**  
&gt; Prop: `http://fiddle.jshell.net/test/11`  
&gt; Attr: `http://fiddle.jshell.net/test/11`  
&gt; 
&gt; **4) Prop then Attr Modification test**  
&gt; Prop: `http://fiddle.jshell.net/test/11`  
&gt; Attr: `http://fiddle.jshell.net/test/11`

Now I am confused about a couple of things, as far as my knowledge goes:  
**Prop:** The value in its current state after any modifications via JavaScript  
**Attr:** The value as it was defined in the html on page load.

Now if this is correct, 

* Why does modifying the `prop` seem to make the `action` fully qualified, and conversely why does modifying the attribute not?
* Why does modifying the `prop` in `1)` modify the attribute, that one makes no sense to me? 
* Why does modifying the `attr` in `2)` modify the property, are they meant to be linked that way?

jQuery attr vs prop?

Apple&#39;s iPad Mini is a smaller clone of the iPad 2 in more ways than we&#39;d want. In JavaScript, the `window.navigator` object exposes the same values for the Mini and iPad 2. My tests so far to detect the difference have not lead to success.

Why is this important? 

As the iPad Mini and iPad 2 screens are identical in pixels but vary in actual size (inches / centimeters), they vary in [PPI][1] (pixels per inch).

For web applications and games to offer a friendly user interface, certain elements are adjusted in size relative to a user&#39;s thumb or finger position, thus, we may want to scale certain images or buttons to provide for that better user experience.

Things I have tried so far (including some pretty obvious approaches):

 - `window.devicepixelratio`
 - CSS element width in cm unit
 - CSS media queries (such as `resolution` and `-webkit-device-pixel-ratio`)
 - SVG drawings in similar units
 - Doing all sorts of CSS webkit transforms for a set time and counting rendered frames with `requestAnimFrame` (I was hoping to detect a measurable difference)

I&#39;m fresh out of ideas. How about you?

**Update**
Thanks for the responses so far. I would like to comment on people voting against detecting iPad mini versus 2 as Apple has uhm, one guideline to rule them all. Okay, here&#39;s my reasoning why I feel it really makes all sense in the world to know if a person is using an iPad mini or a 2. And do with my reasoning what you like.

The iPad mini is not only a much smaller device (9.7 inch versus 7.9 inch), but its form factor allows for a different usage. The iPad 2 is usually held with two hands when gaming unless you&#39;re [Chuck Norris][2]. The mini is smaller, but it is also much lighter and allows for gameplay where you hold it in one hand and use another to swipe or tap or whatnot. As a game designer and developer myself, I&#39;d just like to **know** if it&#39;s a mini so I can choose to provide the player with a different controlscheme if I want (for instance after A/B testing with a group of players). 

Why? Well, it&#39;s a proven fact that the majority of users tend to go with the default settings, so leaving out a virtual thumbstick and putting some other tap-based control on the screen (just giving an arbitrary example here) when the player loads up the game for the first time is what I, and probably other game designers, would love to **be able to** do.

So IMHO this goes beyond the thick fingers / guidelines discussions and is just something Apple and all other vendors ought to do: allow us to uniquely identify your device and **think different** instead of **following** guidelines.

Is there any way I can use the [moment.js](http://momentjs.com/) `format` method on duration objects?  I can&#39;t find it anywhere in the docs and it doesn&#39;t seen to be an attribute on duration objects.

I&#39;d like to be able to do something like:


    var diff = moment(end).unix() - moment(start).unix();
    moment.duration(diff).format(&#39;hh:mm:ss&#39;)

Also, if there are any other libraries which can easily accommodate this sort of functionality, I&#39;d be interested in recommendations.

Thanks!

I&#39;ve seen some websites that when the user scrolls down the page a box would pop-up to the right or left... 

Also, noticed this template: http://www.mvpthemes.com/maxmag/ the designer does a nice job leaving the nav bar fixed on top. 

Now, how are these done? I guess it uses jquery to get the position of the page and to show the box.

Can you please guide me to where I can find a snippet so I can learn to do something like that.

How to enable Bootstrap tooltip on disabled button?

I am currently using the below function to create text that will be displayed using Bootstrap’s tooltip plugin. How come multiline tooltips only work with `&lt;br&gt;` and not `\n`? I prefer that there is not any HTML in my links’ title attributes.

What works

    def tooltip(object)

      object.each do |user|
        tooltip += &quot;#{user.identifier}&quot; + &quot;&lt;br&gt;&quot;

How to make Twitter Bootstrap tooltips have multiple lines?

I&#39;m using Twitter Bootstrap and I have the following:

    &lt;div class=&quot;row&quot;&gt;

        &lt;div class=&quot;span3&quot;&gt;
            &lt;div data-spy=&quot;affix&quot;&gt;
                &lt;form&gt;
                    &lt;!-- inputs and stuff --&gt;
                &lt;/form&gt;
            &lt;/div&gt;
        &lt;/div&gt;

        &lt;!-- span9 and its contents --&gt;

    &lt;/div&gt;

Bootstrap is correctly applying the affix effect on `&lt;div&gt;` and it stays still when I scroll down the page. However, once I resize the page to mobile dimensions and bootstrap responsive effects take place (navbar collapsing/objects aligning nicely under each other), the affixed `&lt;div&gt;` is now on top of other elements of the page and it gets messy. This is happening because `.affix` has `position: fixed` which explains it pretty well.

Now I went to [Bootstrap][1]&#39;s website and resized the page to mobile dimensions, the affixed element (`&lt;ul&gt;` in their case) starts flowing nicely with the page, taking its natural place without going on top of other elements. I have also noticed that once that happens, the class is changed from `affix` to `affix-top`.

I&#39;m not sure if this is their customization or if it&#39;s part of the framework, because the framework is apparently not behaving the same way. Can anyone elaborate on this? I need to have the same behavior on my `&lt;div&gt;` where if the page gets resized to mobile dimensions the affixed element takes its natural place.

**Edit:** My observation is a bit flawed. I noticed that the element on their page initially has `affix-top` and once I scroll below `data-top-offset` it changes to `affix`. It still doesn&#39;t explain why my `&lt;div&gt;` won&#39;t render like their `&lt;ul&gt;` when resized.

How to vertically align a html radio button to it&#39;s label?

I have a list of radio buttons. when I tab through them, seems like only the first radio button or the one that is selected will get focused, the rest of the radio buttons will get skipped.  checkbox didnt have this problem.

Android:placing the radio buttons horizontally

I want to get the selected value from a group of radio buttons. 

  Here&#39;s my HTML:
 
    &lt;div id=&quot;rates&quot;&gt;
      &lt;input type=&quot;radio&quot; id=&quot;r1&quot; name=&quot;rate&quot; value=&quot;Fixed Rate&quot;&gt; Fixed Rate
      &lt;input type=&quot;radio&quot; id=&quot;r2&quot; name=&quot;rate&quot; value=&quot;Variable Rate&quot;&gt; Variable Rate
      &lt;input type=&quot;radio&quot; id=&quot;r3&quot; name=&quot;rate&quot; value=&quot;Multi Rate&quot; checked=&quot;checked&quot;&gt; Multi Rate  
    &lt;/div&gt;

Here&#39;s my js:

    var rates = document.getElementById(&#39;rates&#39;).value;
	var rate_value;
	if(rates ==&#39;Fixed Rate&#39;){
		rate_value = document.getElementById(&#39;r1&#39;).value;
		
	}else if(rates ==&#39;Variable Rate&#39;){
		rate_value = document.getElementById(&#39;r2&#39;).value;
		
	}else if(rates ==&#39;Multi Rate&#39;){
		rate_value = document.getElementById(&#39;r3&#39;).value;
	}  

    document.getElementById(&#39;results&#39;).innerHTML = rate_value;

I keep getting undefined.

How to get value of selected radio button?

i have this radio button (and some other after this one):

    &lt;input type=&quot;radio&quot; name=&quot;group1&quot; value=&quot;Milk&quot;&gt; Milk&lt;br&gt;

But if i want to activate the radio button, i have to click it, clicking the word &quot;Milk&quot; which is to the right of the button, doesn&#39;t activate it. How can i do that?, all the examples i found about radio buttons so far, have the same issue. Thanks in advance.
