pass javascript value to asp.net function
the question says it all : i have a linkbutton to which i pass through CommandArgument a value and i need that value to be a javascript value. Thanks!
Edit :
here is my linkbutton tag :
< asp:linkbutton id="prevBut" runat="server" OnCommand="load_com" CommandArgument=to_place_javascript_string Text="previous" />
and the function :
public void load_com(object sender, CommandEventArgs e)
{ //get the string from e and search through the database for something }
i want to pass the name of a photo that is stored in a variable $.galleria.current.
You need to stop for a moment and think about what the LinkButton is actually doing. It's not magic. It's just posting the form for you.
As such, you can...
define an onsubmit handler to stuff that javascript value into a hidden form field
or, replace that LinkButton with a simple <a onclick="dostuff()"> pointing at a function that stuffs your value into a hidden form field and submits the form
or, replace that LinkButton with a simple <a onclick="dostuff()"> pointing at a function that constructs a URL containing ?myvalue=whatever and redirects to it.
There's no reason you need to involve ASP:LinkButton in any of it. If the built-in ASP.NET controls aren't doing what you want. All you need to do is stop using them.
(Incidentally, you'll have a much happier and more productive career in the .NET world if you stop using Microsoft's Rich Controls in favor of their HTML equivalents. Those things are there so that non-programmers can drag/drop their way to unmaintainable websites. Since you're here, we can assume you're not a non-programmer, and are therefore smart enough to ignore the marketing portions of ASP.NET and use the good stuff directly.)
Are you looking to place a string of javascript code in the command argument or a value which can be accessed via javascript?
If you need a value to be accessible via javascript you could put the command argument value in an attribute of the linkbutton <a href="javascript:void(null)" commandArg="value" >Link Text</a> this would make "commandArg" available via jQuery like $('#linkID').attr('commandArg') . You could obviously name that attrubute whatever you need to.
