[Javascript] Selecting certain areas of text in a string

[Guillaume]

Troy, Nick, Mark,

Thank you very much for your help... I learned a lot by trying your 
suggested solutions and finally came up with a decent solution...

Troy thank you very much, you pushed me very close to where I  was 
trying to get and unlocked my problem almost entirely...

So again thank you folks !

Have a nice day.

Best regards.

> var curr_url =

> alert(curr_url); 
>
> //alertbox should display: http://www.somesite.com/video/somevideo.flv

>
> my_url.replace(curr_url,"http://www.othersite.com/video/othervideo.flv");
>
>  
>
>  
>
> alert(new_url) // will give you the full string of parameters containing

> the url you've now specified.

>> Hi there,
>>
>> Currently trying to change the url of an embedded element in a page...
>> My problem is that many other parameters are passed along the url of
>> the object, in the src property:
>>
>> src="../pluginsv/mediaplayer.swf?file=http://www.somesite.com/video/somevideo.flv&autostart=true&displayheight=202&allowfullscreen=over&controlbar=over&usefullscreen=true&backcolor=0x121212&frontcolor=0xffffff&lightcolor=0x000000&bufferlength=10"
>>
>> I'd like to only rewrite this part: file=http://www.somesite.com/
>> video/somevideo.flv
>> Rest of the parameters should remain untouched...
>>
>> I know I should use String.replace, something like:
>>
>> var str="somevideo.flv!";
>> document.write(str.replace(/somevideo.flv/,"othervideo.flv"));
>>
>> But I have absolutely no idea on how target this piece of text only in the
>> whole src="...", starting from ending file path, from / to .flv
>>
>> Any help would be greatly appreciated.
>>
>> Thank you.
