Need help with the Jquery script in Lift
sailor...@gmail.com
to write the codes. But I can't find the coding standard in Assembla,
so I write the codes with my style first.
1. TestForm.snippet
import _root_.net.liftweb._
import http._
import SHtml._
import util._
import Helpers._
class TestForm extends StatefulSnippet {
def dispatch = {
case _ => render
}
def render = "type=submit" #> SHtml.onSubmitUnit(() =>
println("TEST"))
}
2. test_1.html
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://
www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<body class="lift:content_id=main">
<div id="main" class="lift:surround?with=default;at=content">
<div id="form" class="lift:TestForm?form=post">
<input id="submit" type="submit" value=" S U B M I T "/>
</div>
</div>
</body>
</html>
3. test_2.html (same with test_1.html but with the script in the
header )
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://
www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<body class="lift:content_id=main">
<div id="main" class="lift:surround?with=default;at=content">
<head>
<script>
<script id="jquery" src="http://ajax.googleapis.com/ajax/libs/
jquery/1.6.1/jquery.min.js"
type="text/javascript"></script>
// <![CDATA[
jQuery(document).ready(function(){
jQuery("form").submit(function(){
jQuery(":submit").attr("disabled", "disabled");
});
});
// ]]>
</script>
</head>
<div id="form" class="lift:TestForm?form=post">
<input id="submit" type="submit" value=" S U B M I T "/>
</div>
</div>
</body>
</html>
4. My problem is, test_1 and test_2 calling the same StatefulSnippet
(TestForm), but in test_2 adding the script that prevents clicking
submit more than once, resulting the submit button doesn't work.
( Note : press submit in test_1.html I got the TEST message in
console, but not test_2.html )
Why? And what should I do to actually adding the javascript code to
work with Lift ?

/**
* If you bind functions (i.e. using SHtml helpers) inside the
closure passed to callOnce,
* after your function is invoked, it will be automatically removed
from functions cache so
* that it cannot be invoked again.
*/
def callOnce[T](f: => T): T = {
autoCleanUp.doWith(true) {
f
}
}
Hope it helps

wrote is executed in the client first, and after that then it would be
posted to the server, why the server can't run the submit ?

Could you post a sample app that shows the problem?

Could you be more specific about what you are trying to do? It doesn't
sound lift related, but maybe you meant something different than what
I think.
