Database Operation On Javascript In Mvc

Question

I am working on a mvc project. I have a button in my view which is calling a Javascript function to print the data. Code is as follows:

Solution 1:

You can call a ActionResult in controller from client side using Jquery ajax.

functionPrintDiv() {
        var divToPrint = document.getElementById('printableArea');
        var popupWin = window.open('', '_blank', 'width=300,height=300');
        popupWin.document.open();
        popupWin.document.write('<html><body onload="window.print()">' + printableArea.innerHTML + '</html>');
        popupWin.document.close();
        UpdateDb();
    }

functionUpdateDb();
{    
    $.ajax({
               type: 'POST',
                url: "@Url.Content("/Contrller/ActionResult/")",    
                data : {                          
                                 parameter1:value1,
                                 parameter1: value2
                          },           
                dataType: datatype,
                success:function(result)
                {
                   //Any thing needed to be done on success                  
                }
       });
}

Now write your logic to update Db in your Actionresult in Controller.

Hope it helps.

Solution 2:

In general you never want to allow your View to access the database. That kind of access should be granted on an infrastructure level. I generally would not recommend this but at least do the database call on your Controller and then pass an IEnumerable to the View for the table.

                         your code..
                });

and in controller action

public actionresult GetState(string data)
{
    datatable item = entity.datatable.contains(data);
    entity.entry(item)..State = EntityState.Modified;
    entity.savechanges():
}
