[Lift] problem when use ajaxButton
hi,
please help me, I can't find the reason, the code on gist
http://gist.github.com/175858
def remove(img:String)={
HomePage.removeImg(img)
JsCmds.Run("$('#"+img+"').remove()")
}
var imglist=imgs.map(i =>{
{SHtml.ajaxButton(S.?("delete"), () =>remove(i))}})
bind("list",xhtml,"imgs" -> {imglist})
I'm sure jquery is working on that page, but [ JsCmds.Run("$('#"+img
+"').remove()") ]do nothing.
the buttons are in those s, when click, remove the li wrap it,and
also remove the button itself.
the page sourse in browser:
..
..
delete
..
something wrong I do?
thanks
Lance

I guess maybe a comma is missing in your code, and maybe you are not
use a IDE.

"submit" -> {?("send")}

can work in IE8.
but in Firefox3.5, it can't get "whoField" value out. Maybe it's a
JQuery problem(liftweb 1.0, jquery1.3.2 build in)?

[Lift] How to use "SHtml.ajaxCall"?
Hi,
I try the example "Hello Darwin"(http://wiki.liftweb.net/index.php/
Hello_Darwin), but ajax form can't work correctly.
I try bind submit button:
"submit" -> {?("send")}
but IDE tell me the first param of ajaxCall() must be a JsExp.
Dose lift have any implicit method that convert a string to JsExp?
I don't know how to construct JsExp from String, help please!
