I created a function in javascript like that:
function addNewManufacturer() {
var name = $("#id-manuf-name").val();
var address = $("#id-manuf-address").val();
var phone = $("#id-manuf-phone").val();
var sendInfo = {
Name: name,
Address: address,
Phone: phone
};
$.ajax({
type: "POST",
url: "/Home/Add",
dataType: "json",
success: function (msg) {
if (msg) {
alert("Somebody" + name + " was added in list !");
location.reload(true);
} else {
alert("Cannot add to list !");
}
},
data: sendInfo
});
}
I called jquery.json-2.3.min.js
script file and I used it for toJSON(array)
method.
In controller, I have this Add
action
[HttpPost]
public ActionResult Add(PersonSheets sendInfo) {
bool success = _addSomethingInList.AddNewSomething( sendInfo );
return this.Json( new {
msg = success
});
}
But sendInfo
as method parameter becomes null.
The model:
public struct PersonSheets
{
public int Id;
public string Name;
public string Address;
public string Phone;
}
public class PersonModel
{
private List<PersonSheets> _list;
public PersonModel() {
_list= GetFakeData();
}
public bool AddNewSomething(PersonSheets info) {
if ( (info as object) == null ) {
throw new ArgumentException( "Person list cannot be empty", "info" );
}
PersonSheets item= new PersonSheets();
item.Id = GetMaximumIdValueFromList( _list) + 1;
item.Name = info.Name;
item.Address = info.Address;
item.Phone = info.Phone;
_list.Add(item);
return true;
}
}
How could I do in action method when the data was sent with POST ?
I don't know how to use. Also, it is possible to send back the response (to ajax) via JSON ?
This question is related to
jquery
ajax
asp.net-mvc
json
var SendInfo= { SendInfo: [... your elements ...]};
$.ajax({
type: 'post',
url: 'Your-URI',
data: JSON.stringify(SendInfo),
contentType: "application/json; charset=utf-8",
traditional: true,
success: function (data) {
...
}
});
and in action
public ActionResult AddDomain(IEnumerable<PersonSheets> SendInfo){
...
you can bind your array like this
var SendInfo = [];
$(this).parents('table').find('input:checked').each(function () {
var domain = {
name: $("#id-manuf-name").val(),
address: $("#id-manuf-address").val(),
phone: $("#id-manuf-phone").val(),
}
SendInfo.push(domain);
});
hope this can help you.
To post JSON, you will need to stringify it. JSON.stringify
and set the processData
option to false.
$.ajax({
url: url,
type: "POST",
data: JSON.stringify(data),
processData: false,
contentType: "application/json; charset=UTF-8",
complete: callback
});
Use JSON.stringify(<data>)
.
Change your code: data: sendInfo
to data: JSON.stringify(sendInfo)
.
Hope this can help you.
Your PersonSheets has a property int Id
, Id
isn't in the post, so modelbinding fails. Make Id nullable (int?) or send atleast Id = 0 with the POst .
You don't need to call $.toJSON
and add traditional = true
data: { sendInfo: array },
traditional: true
would do.
