[Lift] Re: slow down ajax?
Short story - after a fresh start with your instructions... all is
well.
I actually just downloaded the zip file into a liftweb temp directory,
then entered that and ran mvn as you said. After a huge compile, I
changed all 3 of my Lift references in the existing project pom.xml to
'1.1-SNAPSHOT' (which may have been a problem on my last attempt), and
jetty started perfectly.
So, now I will delve back into the mechanics of my program, and tinker
along.
Thanks for your help, and stay tuned for the next exciting episode...
Lift is fun!

Delete any earlier jar so you rule out that possibility. Also, if you turn
on debug output in maven (-X) it might tell you the path that it's using to
invoke the compiler so you can see which jar it's using if any.

See the jsFunc parameter. Essentially you are specifying your
function
call that may have one parameter. To your parameter list List we'll
add a new parameter which is the ajax invocation function. In other
words your code gets that function that does the ajax call meaning
that you have the control over when the ajax call is made.

Having
def ajaxText(value: String, jsFunc: Call, func: String = JsCmd)
jsFunc parameter is a Call which is defined as:
case class Call(function: String, params: JsExp*) extends JsExp
So by this you represent a javascript function invocations.
So assuming somewhere you have a javascript function like:
function myFunc(myParam, callback) {
// do some logic
callback()
}
in the snippet we have something like:
ajaxText(task.dueOn.toString,
Call(myFunc, Str(some_param_value))
v = { task.dueOn(v.toLong).save; reDrawTasks();})
As you can see we called Call(myFunc, Str
(some_param_value)) .. .we provided the JS function name and one
parameter. Lift will add the second parameter which is the callback
function. This callback function represents the actual ajax call and
since it is a callback you can invoke it whenever you want inside
'myFunc' javascript function. In other words you can defer the
actual
ajax call as you see fit.
Now myFunc function declaration can be:
1. In your own .js file
2. Written in the script tag inside your html
3. Generate using Lifts' JS absctrations using JsCmds.Function()
object such as:
JsCmds.Function(MyFunc, List(myParam, callback),
a_JsCmd_expression_which_is_the_function_body)
The main point in all this is that you can defer the actual ajax
call.
You know better if this fits your case.

add a new parameter which is the ajax invocation function. In other
words your code gets that function that does the ajax call meaning
that you have the control over when the ajax call is made.

So far, all good.
The problem is that Lift's ajax starts ('onblur') before it has a

What I need is a way to tell Lift to wait until after my parser has

I like the ajax style, so I don't want to make a 'submit' form, and
'onchange' won't do it either, because the value is actually changed
twice (once to a formatted date, once to millis).
What I need is some way to say, 'OK to start ajax now'!

I have enabled datepicker for the ajaxText field via jQuery, and have
a parsing function attached an event listener, so when datepicker
finishes, the date is converted to millis, ready for Lift to send back
to the server and save.
So far, all good.
The problem is that Lift's ajax starts ('onblur') before it has a
chance to see the new date value, so the new value is never saved.
What I need is a way to tell Lift to wait until after my parser has
had a chance to write the changed value.
I like the ajax style, so I don't want to make a 'submit' form, and
'onchange' won't do it either, because the value is actually changed
twice (once to a formatted date, once to millis).
What I need is some way to say, 'OK to start ajax now'!
