Thanks Olav for taking the time to help me.
I now have 2 errors in databaseworker.js:
"alert is not defined" at-
wp.onerror = function(errorObject)
{
alert("Error in workerPool: "+errorObject.message+" on
line"+errorObject.lineNumber);
};
And: "serverresponse is not defined" at -
catch (ex)
{
wp.sendMessage("Error: No valid data found. Data
was:"+serverresponse,message.sender);
return;
}
What should I change?
