Json parse and push web sql database in Sapui5 - ajax

Question

I will design a a sample. My project will take all json data and insert to my web sql database.Firstly I used ajax for take my data and tried parse it. When I parsed , I dont access my json fields.
var oModel = new sap.ui.model.json.JSONModel();
var aData = jQuery
.ajax({
url : "http://../DataSource?format=json&key....",
dataType : "json",
success : function(data, textStatus, jqXHR) {
var JsonData = data;
oModel.setData(JsonData);
},
error : function(jqXHR, textStatus, errorThrown) {
}
});
obj = JSON.parse(oModel);
var myTextField = obj.Name;// This is not working
console.log(myTextField);
Also ı tried this.
var model = new sap.ui.model.json.JSONModel();
model.loadData("http://.../DataSource?format=json&key=...");
obj = JSON.parse(model);
var myTextField = obj.Name;
console.log(myTextField);
This my database. I want insert all name and surname field.
function populateDB(tx) {
tx.executeSql('DROP TABLE IF EXISTS emre');
tx.executeSql('CREATE TABLE IF NOT EXISTS emre (id unique, data)');
tx.executeSql('INSERT INTO emre (id, data) VALUES (?,?)', [ name ,
surname ]);
}

You seem to try parsing the model, but that is not a JSON structure but a UI5 object which happen to contain the JSON structure.
But why would you parse the JSON in the first olace?? If your AJAX call finishes successfully, and stores the retrieved data in your model, you can simply access it from the model using
model.getProperty("/path/to/your/property");
Have a look at the model API in the docs, there it is all well explained
EDIT to get to the data after it is loaded, use the attachRequestCompleted event handler:
var model = new sap.ui.model.json.JSONModel();
model.attachRequestCompleted( function(){
console.log(model.getProperty("Name"));
});
model.loadData("http:.../DataSource?format=json&key=...);
