Hi, all, Please consider this construct:
function rowCallback(dbRow){ // Notes below ref to this scope } myDbDriver.query({ sql:"SELECT * FROM T", callback: rowCallback }); That hypothetical code would run the given query and call the given callback for each row. What i would like to do here, but don't know how, is: before the callback is called, i would like to inject some custom variables such that they could be resolved unqualified in the callback. For example, let's extend the above callback: function rowCallback(dbRow){ // dbRow == Array or Object of db row data. // rowNumber == the current row number // colNames == Array of column names // colCount == column count var i; for( i = 0; i < colCount; ++i ){ ... do something with each column ... print(colNames[i]+'='+dbRow[i]); } } How can i (or is it even possible) to inject variables this way from a native-level InvocationCallback before it passes on the call callback() back to script-land? If i can do this, the callback wouldn't need any parameters - all state could be injected this way. i know i could build a custom object with these properties and set it as the "this" for the call, but i'm looking for a way where the callback does not have to this.qualify each of the symbols (and without using the "with" keyword). :-? -- ----- stephan beal http://wanderinghorse.net/home/stephan/ http://gplus.to/sgbeal -- -- v8-users mailing list v8-users@googlegroups.com http://groups.google.com/group/v8-users --- You received this message because you are subscribed to the Google Groups "v8-users" group.
