WriteFieldValue Method

Write current segment field value.

Syntax

idocwriter.writeFieldValue(fieldName, value, [callback])

Callback

The 'callback' parameter specifies a function which will be called when the operation completes (or an error is encountered). If the 'callback' parameter is not specified, then the method will block and will not return until the operation completes (or an error is encountered).

The callback for this method is defined as:

function(err){ }

'err' is the error that occurred. If there was no error, then 'err' is 'null'.

'err' has 2 properties which hold detailed information:

err.code
err.message

Remarks

Use the WriteFieldValue method to specify the next Field-Value pair to be written in the current segment.

It is important to realize that fields must be written in the same order they should appear on the target IDoc document. The IDocWriter component does not automatically enforce ordering rules.

Example IDocWriter Code:

idocwriter1.StartIDoc()
idocwriter1.WriteControlRecord()
idocwriter1.StartSegment("Segment1")
idocwriter1.WriteFieldValue("Field1", "Value1")
idocwriter1.WriteFieldValue("Field2", "Value2")
...
idocwriter1.EndSegment()
idocwriter1.StartSegment("Segment2")
idocwriter1.WriteFieldValue("Field1", "Value1")
...
idocwriter1.EndSegment()
...
idocwriter1.EndIDoc()
