How can we perform dml operations in visualforce page?

Hi Pranav,

If you want to perform DML operation on Vf page, you can use sforce.connection in your javascript and then perform your required DML operations.

For Example:- if you want to insert the records, the use below format:-

var instanceOfRecord = new sforce.SObject('Name of Object');
var results = sforce.connection.create([instanceOfRecord]);

Thanks.
