I am probably confused on what exactly is going on in the request /
response cycle here, but I am trying to show a table cell after a
calculation is performed, and I can't seem to get the js to run. The
JS is being called in the showResults method that is bound to the
submit action. I am guessing that the submit action is reloading the
page, so there is no opportunity to run the js. Any suggestions on
how I should be doing this instead? I am learning lift, and I am
working on an app that needs to be completely stateless (no db
backend, no cookies, no session).
I have the following for my page:
<lift:surround with="default" at="content">
<table>
<tbody>
<tr>
<td>
<lift:mortality.calcForm form="POST" id="mortalityForm">
Age: <f:age><input
type="text"/></f:age><br/>
Male: <f:male><input
type="text"/></f:male><br/>
<f:submit><input type="submit"
value="calculate"/></f:submit>
</lift:mortality.calcForm>
</td>
<td id="mortalityResult" style="display:none;" >
<lift:mortality.doCalculate>
Life Expectancy: <r:le>50</r:le>
</lift:mortality.doCalculate>
</td>
</tr>
</tbody>
</table>
</lift:surround>
Then in my snippet code I have the following:
class Mortality {
object ageVar extends RequestVar[Int](S.param("age").map(_.toInt)
openOr 0)
object maleVar extends RequestVar[Boolean]
(S.param("male").map(_.toBoolean) openOr false)
var le = "0"
def calculateLifeExp = {
val calcLE = Annuity2000.lifeExpectancy(ageVar.is, maleVar.is)
le = String.format("%.2f",double2Double(calcLE))
}
def doCalculate(xhtml:NodeSeq):NodeSeq = {
calculateLifeExp
Helpers.bind("r", xhtml,
"le" -> le.toString
)
}
def showResults():JsCmd = {
JsCmds.Run("$('#mortalityResult').show();alert('I ran')")
}
def calcForm(xhtml:NodeSeq):NodeSeq = {
Helpers.bind("f", xhtml,
"age" -> SHtml.text(ageVar.is.toString, v => ageVar(v.toInt)),
"male" -> SHtml.text(maleVar.is.toString, v =>
maleVar(v.toBoolean)),
"submit" -> SHtml.submit("Calculate", showResults),
"le" -> le.toString
)
}
}
