JQuery code snippet interpretation

Hey guys!

I have a div in a page called h-accordion.
After this div, there is a second one. When I pres on the first one, the second one toggles (hidden/shown).

The whole set repeats itself several times in the page - there are multiple "sections" which the user can "open" one by one.

I have the following code to make it work:

$('.h-accordion').click(function(){	<!--on click on this element-->
  if($(this).next().is(':hidden')){	<!--if the next element of the title is hidden-->

     $(this).next().slideDown();	<!--peform the slide down-->
     $(this).attr('rel',"opened");	<!--change the state to openened -->
  } else {		                <!--if the next element of the title is not hidden-->
     $(this).next().slideUp();		<!--perform the slide up-->
     $(this).attr('rel',"closed");	<!--change the state to closed -->
}
return false;
}).css('cursor', 'pointer').next().hide();

Could you please tell me what the last line does? Can`t figure it out with the jQuery reference...
Many thanks!

It sets the h-accordion to have a style attribute "cursor" set to "pointer" (which obviously sets the mouse cursor to a pointer when mousing over h-accordion). Then, it hides the element following h-accordion.

FYI, it may not be clear if you are new to jQuery, so I thought I'd let you know that jQuery can chain statements. So the above basically looks like this:

JavaScript

$('.h-accordion').click(/* ... */).css(/* ... */).next().hide();

So it gets the elements with the "h-accordion" class, applies a click handler to them, applies some CSS to them, moves to the element following each of them, then hides those following elements.

The click handler will hide/show "following" elements. The "last line" (as you call it) will ensure those "following" elements are initially hidden.

It sounds as if you may be asking for something like:

var words = classname.split(' ');
for (var item in words) {
    if (sometext.indexOf(words[item]) != -1) {
        return true;
    }
}
return false;

How to get file size without using ActiveX

JavaScript in a web page is sandboxed to prevent it from being able to do such things as access the file system. Therefore, the only way to get around this is to use a third party control, or if your app will only run on IE on Windows, you can use the ActiveXObject to create an instance of the Scripting.FileSystemObject and access the file size with that.

How to change the "src" value in a <embed> using javascript function ?

LockedOut13-Jul-11 7:28

Hey i was designing a website which plays a no of music station live. For this i used the Media Player for website and setted its src ='http://www.bollywoodhungama.com/scripts/bollywoodhungama.asx'

Now i want to have Buttons through javascript and want that if a user click on the buttons than that particular channel should be switched.

<HTML>
<HEAD>
<script type="text/javascript">
  
    function change()
   {
   window.location.reload();
     function chg()
      {
      document.getElementById("myplayer").setAttribute("src", "mms://216.185.43.237/radiocity 1");
      }
   }
   
  
  
</script>  

</HEAD>
<body>    
<embed id="myplayer" type="application/x-mplayer2" pluginspage="http://www.microsoft.com/Windows/MediaPlayer/" name="mediaplayer1"  showstatusbar="true" enablecontextmenu="false" autostart="false" width="320" height="60" loop="false" src="http://www.bollywoodhungama.com/scripts/bollywoodhungama.asx " />
</embed> 

<input type='button' onclick='change()' value='Change'/>

</body>
</HTML>

Here i have used this Change() function to reload the page so that the station should stop playing. and now here i have added function chg() inside this and i want that after reload the src value should get changed and on starting the player another station should start playing.

But this is not working ?

Is it possible to change the src to new value after page reload ?

Please suggest.

All i want is that the "src" value should get change anyhow.....and one should be able to switch playing stations.

Hi
window.location.reload()
does this funtion load the html document again ?
if yes, document will be new parsed include javascript ?

does embed support ID or only NAME ?

does "myplayer" have .src allready and you create this attribute again ?

where will function chg() be called ?

onclick

Media Player from Microsoft .... try HTML-5-Media (webM, ogg)
or try Quicktime (if you want go to my webpage www.twseiten.com
for informations).

I think twseitex is correct, your reload is a short circuit to changing the src value.

Try removing the reload and just setting the src value with the function.

<script type="text/javascript">
  
    function change()
   {
      document.getElementById("myplayer").setAttribute("src", "mms://216.185.43.237/radiocity 1");
   }

</script>

Access permissions on the target folder / file, sounds like the problem.

Have you checked the privileges for the end points and compared the one that works with the one that doesn't?

I don't know I am right or not but when you add flash plugin by <object> tag then you can provide installation link when you don't find plugin. It will detect if plugin install or not and if not installed it will show the link where to install it.

I might be wrong but you should search on that may be it help you.

Hi,

Example for Flash in use of video ....

I code for Internet Explorer only HTML-tag <object>.
For Opera and Co.: Dynamically create flash with no problems.
test-flash-file must exist for create OBJECT dynamically
f.e. check out Shockwave-plugin.

<object type="application/x-shockwave-flash" width="1px" height="1px" data="your_testfile_must_exists.swf" style="visibility:hidden">

Better: User HTML-5-Video like WebM from Google or Quicktime with HTML.

script tested in IE 8: dynamically create not possible

// +++++ check document.body
if(X00){X00=(document.body!=null);}

if(X00)
{
// +++++ IE create errror during build OBCECT object
// in use if createElement() and .innerHTML and normalize() too
//
// X02=document.createElement('OBJECT');
// X00=(X02!=null);
//
// if(X00)
// {
// var X03=document.body.appendChild(X02);
// X00=(X03!=null);
// }
//
// if(X00)
// {
// var X04=document.createElement('PARAM');
// X00=(X04!=null);
// }
//
// if(X00)
// {
// var X05=X03.appendChild(X04);
// X00=(X05!=null);
// }
//
// if(X00)
// {
// X05.name="movie";
// X05.value="path" + "your_flash_file.swf"; // it must exists (blanc video)
//
// X03.style.visibility='hidden';
//
// try
// {X03.classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000"; // 20100928 http://kb2.adobe.com/cps/415/tn_4150.html
//
// X00=(X03.classid!='');
//
// X00=document.body.removeChild(X03);
// }
// catch(e){X00=false;}
// }
//}
