getValue

Returns the value of a scalar data object or item within an array data object.

Syntax
value = AM_data.getValue(id, row_index, col_index)
Parameters
id(required). Identifier of the data object.
row_index(optional). Zero based row index of the array data object item. (default "0")
col_index(optional). Zero based column index of the array data object item. (default "0")
Return Value
valueValue of scalar data object or array data object item.
Example
This example demonstrates accessing a scalar data object directly as property of the data scripting object AM_data. The example first sets the value of the scalar data object "did_sometext" to "The quick brown fox". The value of the scalar object "did_sometext" is then presented in an alert message dialog box. Note the use of "alert" assumes this script is part of a HTML resource.
AM_data.did_sometext = "The quick brown fox";
alert(AM_data.sometext);
Example
This example demonstrates working with array data Objects using the data scripting object.
Assume we have declared an array data Meta Object with a unique identifier of "did_myarray" having the following values. Note the row and column indexes are bolded.
Row \ Column0123
0[100200300400]
1[500600700800]
2[900100011001200]

var number = AM_data.getValue("did_myarray" "1","2"); // number now equals 700. i.e. we retrieved the value within our array at row index 1 and column index 2. Note these indexes are zero based.
