I am working on MVC 5 project.

What I have tried:

Here I trying to remove json object.

JavaScript

var hidJson = JSON.parse(hidvalue);      
        $.each(hidJson.Form5.Projects, function (i, obj) {
            if (obj != null) {
                if (obj.idPartnerProject == idPartnerProject) {

                    delete hidJson.Form5.Projects[i];              
                }
            }
        });

Because that's not how arrays work.

You already are. To do what you think needs to happen, you copy the not null elements to another array. Or learn how to check element for being null.

I have changed the code like this,

JavaScript

hidJson.Form5.Projects.splice(i, 1);

and removed this code:

JavaScript

delete hidJson.Form5.Projects[i];

Now the array refreshed !!!
