Method Description

iterator.getNextRow()

Get the data from the next row.

Syntax

bool = iterator.getNextRow()

Parameters

The 'iterator.getNextRow' method takes no parameters

Results

The 'iterator.getNextRow' method returns bool:

Remarks

This method loads the iterator with property values for the next row in the table. If this is the first operation on the iterator since it was created then the method will return the first row in the table. The initial or current position in a table can be modified using iterator.setNextRow().

The return value from the method indicates whether new row values were available - or whether the end of the table had been reached.

Example

This example uses the rb.page.iterateHeader to create an iterator and then steps through each row in the virtual table - in this case each row represents one of the HTTP headers provided by the client.

rb.page.write('<h1>HTTP Headers</h1>\n');

var iter = rb.page.iterateHeader();

rb.page.write('<table border="1">\n');
while (iter.getNextRow()) {
   rb.page.write('<tr><td>'+iter.name+'</td><td>'+iter.value+'</td></tr>\n');
}
rb.page.write('</table>\n');
