How can i modify this example for add position in jQuery? I would like - if i click on .here then **table id = new** should show me on this clicked TD. Additionally if i clicked outside **table id = new** then this should hide.

How can i make it?

Answer: 
from here:

<http://www.mongodb.org/display/DOCS/Server-side+Code+Execution#Server-sideCodeExecution-%7B%7B%24where%7D%7DClausesandFunctionsinQueries>

"Note: if a normal data-driven BSON query expression is possible, use that construction. Use $where only when you must it is significantly slower."

For your second question: can you do 

```
{ a : { $gt: 0.3 } }

```
"Javascript executes more slowly than the native operators listed on this page, but is very flexible. See the server-side processing page for more information."
