How use Dmx.parse with dynamic variables

[kfawcett]

I posted the recommended way in the link above, but pulling it out to make it easier. It mentions you must wait until the data is loaded before accessing it. One way to do that is using ondone event on a server connect.

I’m curious why you are not using the Dynamic Events of ServerConnect to trigger the sc_log, instead of creating a script for it.

You can use dmx.parse to parse expressions inside javascript, so adding dmx.parse('serverconnectheader.data.querysigheader[0].sig') would give you the signature json. But you have to wait until the data is loaded before accessing it, otherwise you just get an undefined .

The code I gave before also works with server connect, just hook in the done event from server connect and execute the function to generate the signature.

<dmx-serverconnect id="serverconnectheader" url="<<action_url>>" ondone="regenerateSig()"></dmx-serverconnect>
<script>
function regenerateSig() {
  $('.sigPad').signaturePad({displayOnly:true}).regenerate(dmx.parse('serverconnectheader.data.querysigheader[0].sig'));
}
</script>
