Im using a couple of JSON calls to render data, etc etc. In order to keep the proper key value, I am storing it in a tag.
I have this in several places in my code, none of which cause an issue like this one is. Here is the jQuery:
The call that "sets" the value:
$("a[id^='planSetupAddNewPlan']").live('click', function() {
var x = $(this).attr('id');
x = x.substring(19);
$("#hidPlanSetupCurrentGroupKey").val(x);
$.getJSON("/GroupSetup/PlanSetupAddNewList", { GroupKey: x }, function(data) {
$("#planSetupAddNew").html('' + data.TableResult + '');
alert('First Inside 2 ' + x);
$.blockUI({ message: $("#planSetupAddNew") });
});
});
The call that "gets" the value:
$("#ddlPlanSetupAddNewProduct").live('change', function() {
var a = $("#hidPlanSetupCurrentGroupKey").val();
var prod = $(this).val();
alert(a);
$.getJSON("/GroupSetup/PlanSetupChangePlanList", { GroupKey: a, Product: prod }, function(data) {
if (data.Message == "Success") {
$("#planSetupAddNewPlan").html('' + data.TableResult + '');
} else if (data.Message == "Error") {
//Do something
}
});
});
Here is the html in question:
<div id="planSetupAddNew" style="display:none; cursor: default;">
<input type="hidden" id="hidPlanSetupCurrentGroupKey" />
<div id="planSetupAddNewData">
</div>
</div>
In the first section, the alert ('First Inside 2 ' + x) returns what I expect (where x = the key value), and if I add a line to display the contents of the hidden field, that works as well:
ie.
var key = $("#hidPlanSetupCurrentGroupKey").val();
alert(key);
In the "alert(a);" call, I am getting "undefined". I have looked at the other code in the same view and it is the same and it works. I must be missing something, or have some sort of mistype that I havent caught.
Just an overview of the controller events: The first call (/GroupSetup/PlanSetupAddNewList) will return an html string building a "form" for users to enter information into.
The second call (/GroupSetup/PlanSetupChangePlanList) just changes a second dropdown based on the first dropdown selection (overwriting the html in the div).
If you need more info, let me know!
Any thoughts/tips/pointers/suggestions?!?!
Thanks for all your help :)
