I have the following JavaScript to fill in some radio buttons using single line fields that are populated with data following a lookup of a stored procedure. I need to postpone the execution of the functions using case statements until after the view has populated the single line fields. Can someone Help?

$(document).ready(function() {
$('.checkbox').click(function () {

if($('input[value="yes"]').is(':checked')) //edit the value here to use your own.
{
$('.Submit').show();
}
else {
$('.Submit').hide();
}
});
});
$(function() {
$(document).ready(function () {
var value = $('. v_S06grwPlanSub input').val();
switch (value){
case "1":
document.getElementById('Field179-0').checked = true;
break;
case "2":
document.getElementById('Field179-1').checked = true;
break;
case "3":
document.getElementById('Field179-2').checked = true;
break;
case "4":
document.getElementById('Field179-3').checked = true;
break;
default:
alert(value);
}
});
});
$(function() {
$(document).ready(function () {
var value = $('. v_gpStudyWork input').val();
switch (value){
case "1":
document.getElementById('Field181-0').checked = true;
break;
case "2":
document.getElementById('Field181-1').checked = true;
break;
default:
alert(value);
}
});
});
$(function() {
$(document).ready(function () {
var value = $('. v_recommendation input').val();
switch (value){
case "1":
document.getElementById('Field182-0').checked = true;
break;
case "2":
document.getElementById('Field182-1').checked = true;
break;
case "3":
document.getElementById('Field182-2').checked = true;
break;
case "4":
document.getElementById('Field182-3').checked = true;
break;
case "5":
document.getElementById('Field182-4').checked = true;
break;
case "6":
document.getElementById('Field182-5').checked = true;
break;
default:
alert(value);
}
});
});

I have solved this problem by rewriting your recommendation for "How to fill checkboxes from a database" please see the comments on that question for a solution to delaying the trigger of the view.

I know this is an older question, but I had the same issue with a very complex form and I believe I found an elegant solution. If you have code that you want to run once after a lookup populates a field, either at the beginning or later on based on another action, jQuery has a very handy "ajaxStop" action.

//If after page loads, then this will be in $(document).ready(function(){...
//otherwise, this can be used in any other method or click/change event handler.
$(document).one('ajaxStop',function(){ 
  //Execute your run-once code here
});

This will attach an event that will only run once, that will be run once ajax has completed, which is when the lookup on a field has completed.

you will need to include a timeout statement in there to delay it. I find that for lookup most lookups happen in a half second to a full second. If there is no values in a field you can use a timeout to test a field and retest every so often until you know its filled and then proceed.
