Question

I have bind some variables to the input fields on $(document).ready

var appdetail = kendo.observable({
    addAppName: "TESTAPP",
    addAppId: "13579"

});

kendo.bind($("#formAdd"), appdetail);

the form is inside a modalview. When I open the modal view I can see "TESTAPP" and "13579" as the default values. The problem is, when I click the button, I am calling a function AddRecord using data-click.. and in this function I am not able to get the values of the forms in a way like

var application_name = appdetail.get("addAppName");

is there a way to make the values available in other functions?

I am adding the HTML & JS code.. When click the ADD button, default values (TESTDB & 13579) are not comming to my modalview window. All fields are blank. When I click the Authorize button on the dialog, TESTDB which is the default value is returning as the alert message whatever the dialog input field is.

the current code is

Javascript :

var app = new kendo.mobile.Application(document.body, {layout: "mobile-tabstrip", loading: "<h1>Please wait...</h1>"});

var appdetail = kendo.observable({
    addAppName: "TESTAPP",
    addAppId: "13579"
});


kendo.bind($("#formAdd"), appdetail);


//alert(appdetail.get("addAppName"));



function closeModalViewAdd() {
    $("#modalview-app-add").kendoMobileModalView("close");
};


function showWindow() {
  $("#modalview-app-add").data("kendoMobileModalView").open();


}

function addToJson() {
  alert(appdetail.get("addAppName"));
 // console.log(appdetail.addAppId);
}

Solution

I recommend making use the data-model property of the view and modal-view. 

<div data-role="modalview" id="modalview-app-add" 
style="width: 95%;" data-show="bindNewDataVar" data-model="appdetail">

and 

<div id="applications" data-role="view"
data-title="Defined Applications" data-layout="default" data-model="appdetail">
