The collection has not been initialized.It has not been requested or the request has not been executed. It may need to be explicitly requested."[Solved]

Issue with JSOM:

If you are tired of searching the solution for the below issue while working with JSOM. You can simply replace the "Format B" with "Format A".


Error Message: "The collection has not been initialized. It has not been requested or the request has not been executed. It may need to be explicitly requested."

Format A:

context.executeQueryAsync(        

        Function.createDelegate(this, this.OnSuccess,

        Function.createDelegate(this, this.OnFailure)

        );

Format B:

context.executeQueryAsync(Onsuccess, OnFailure);

Good Luck !
