Better definition for jq escaping script

[ottuzzi]

Hi,

on page[1] you can see the proposed jq script to escape period and colon characters as they are problematic as css selectors: I found that even $,{ and } need to be correctly escaped.

Here is the proposed change:

function jq(myId) {
   return '#' + myId.replace(/(:|\.|\{|\}|\$)/g,'\\$1');
}

Please let me know what you think about this change.

Thanks Bye Piero
