problem with the block.id

[Davide Longo]

Hi all,

I have a problem with the block.id.
the ID of the block is automatically created in the creation of the block, where the special characters are also used, and this does not allow to use the block.id as a field of an array (if the generated ID contains for example a comma, I have problems with functions such as split (" , "))

do you have the solution for this ? is possible to change the ID creation for not use the special characters (my best way) ?

thanks at all !

The Block IDs are generated by Blockly.utils.genUid(). The character set is defined in Blockly.utils.genUid.soup_. We include as many characters as possible to keep event messages as short as possible. We hope to eventually pass these over the network as part of collaboration support.  If you limit the characters used in your app, you should increase the length used in Blockly.utils.genUid() to ensure ID conflicts remain statistically impossible.

Hi Davide

  I had a similar issue - see https://groups.google.com/forum/#!topic/blockly/jk3T1_e5de0, where % was causing an issue.

  I actually avoided my issue when I moved from a PHP backend (which I only used for institution hosting reasons) to using Node JS - there were other reasons as well.

  However - I did also try encoding the id - but didn't get to use my solution in anger - it did seem to work though.

  You may just get away with keeping the id in quotes...

  Hope this helps

P.S. I use ids a lot for linking blocks to other blocks - it works well.

Can I set the Id of a block with only numbers.
Please reply!!!
