I thought MVC3 can bind JSON data to model by default.
but this code
server:
[HttpPost]
public ActionResult Save(IList<int> IDs)
{
return null;
}
client:
$.post('@Url.Action("Save", "Users")', {'IDs' : [1, 2, 3]}, function() {});
don't work. Why ??
Your code sends IDs[]=1&IDs[]=2&IDs[]=3.
You need send IDs=1&IDs=2&IDs=3.
Set traditional:true parameter to use the traditional style of param serialization.
$.ajax({
url: '@Url.Action("Save", "Users")',
type: 'post',
data: {'IDs' : [1, 2, 3]},
traditional:true,
success: function() {
// ...
}
})
You need to send your data as application/json:
$.ajax({
type: 'post',
url: '/Users/Save'
data: JSON.stringify({'IDs' : [1, 2, 3]}),
contentType: 'application/json; charset=utf-8',
success: function() {
// ...
}
});
This might be the same as the problem I ran into a while ago. Check out this SO question Post Array as JSON to MVC Controller
You have to apply JSON.stringify
$.post('@Url.Action("Save", "Users")', JSON.stringify({'IDs' : [1, 2, 3]}), function() {});
