Ext.util.JSON.decode(resp.responseText).x Syntax Question

[StevenInc]

I have a json response like the following:

{"DATASET":1,"ROWS":[{"INSERT_ID":22}],"STARTROW":1.0,"ENDROW":50.0}

And I am trying to access the INSERT_ID value.

This does not work:

var insert_id = Ext.util.JSON.decode(resp.responseText).INSERT_ID;

Any advice would be greatly appreciated.

Thank you.

Do you not see the structure of your own JSON data?

This should work:
Ext.util.JSON.decode(resp.responseText).ROWS[0].INSERT_ID

Thank you,
That makes sense and it works.
