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 ?

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>

Error: Access to restricted URI denied" code: "1012 [Break On This Error]

I used same code for another page and it worked. But suddenly its giving this error.
I pass projects.xml as xml_file to the function.

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;}

Efficiency of adding arrays to an array

Online.Cop8-Jul-11 1:43

I have a large list of authors, book titles, and comments in an SQL database. I am able to pull those records with PHP.

I want to populate a web form with this information dynamically (Javascript), but since I have never used AJAX or json, I've not known how to do this any other way.

So what I've done is have my PHP generate a 2D Javascript array which contains all of the entries like this:

var author_title_comment = new Array();

author_title_comment.push( new Array("Author 1", "Title 1", "Comment 1") );
author_title_comment.push( new Array("Author 2", "Title 2", "Comment 3") );
...
author_title_comment.push( new Array("Author 3999", "Title 3999", "Comment 3999") );
author_title_comment.push( new Array("Author 4000", "Title 4000", "Comment 4000") );

It's not pretty, but it functions well locally.

The same thing could probably be re-written like this:

var author_title_comment = [];

author_title_comment[author_title_comment.length] = new Array("Author 1", "Title 1", "Comment 1");
author_title_comment[author_title_comment.length] = new Array("Author 2", "Title 2", "Comment 2");
...
author_title_comment[author_title_comment.length] = new Array("Author 3999", "Title 3999", "Comment 3999");
author_title_comment[author_title_comment.length] = new Array("Author 4000", "Title 4000", "Comment 4000");

Since the push() function can handle more than a single entry[^], would this be more efficient:

var author_title_comment = new Array();

author_title_comment.push(
   new Array("Author 1", "Title 1", "Comment 1"),
   new Array("Author 2", "Title 2", "Comment 3"),
...
   new Array("Author 3999", "Title 3999", "Comment 3999"),
   new Array("Author 4000", "Title 4000", "Comment 4000")
);

So I can either 1: use author_title_comment.push( new Array("Author 1", "Title 1", "Comment 1") ); on every element I want to add. 2: use author_title_comment[author_title_comment.length] = new Array("Author 1", "Title 1", "Comment 1"); on each element, or 3: use a single push() with all 4000 elements as additional parameters.

Or #4, learn a better way to do this and have the content dynamically generated whenever the user adds/removes a new author name, book title, or comment. Poke tongue | ;-P

JavaScript

function goUrl(url)
{
    var temp = url;
    return function() { location.href = temp; };
} //function goUrl(url)

This will do the trick as the onClick handler needs to receive a function.

Cheers!
