I want to pass a value to this JavaScript from the database (using datareader in asp.net(C#)).
The script is from http://www.dynamicdrive.com/dynamicindex14/leftrightslide.htm
I need to set a pass value in the below line:
leftrightslide[cnt] = '<a href="MYWEBPAGE"><img src="MYIMAGE FRM DATABASE.gif" border=1></a>';
cnt++;
So the value of the datareader would be passed into the JavaScript array.
See following:
http://www.velocityreviews.com/forums/t76971-populating-javascript-array-from-vb-net.html
Create string from serverside using datareader and register it.
OR
use RegisterArrayDeclaration(arrayName, arrayValue) from server side. See following for this:
http://msdn.microsoft.com/en-us/library/aa479302.aspx
You can use a webservice
you have to use the script manager http://msdn.microsoft.com/en-us/library/system.web.ui.page.clientscript.aspx for doing this. check the link it will help.
