问题 Ext.each(boundsExtend, function(value) { if(value != record.ID) break; }); So how do I break or continue Ext.each loop? 回答1: From the docs: If the supplied function returns false, iteration stops and this method returns the current index. So as in the OP's example (assuming record is in scope and non-null): Ext.each(boundsExtend, function(value) { if (value != record.ID) { return false; } // other logic here if ids do match }); Note that returning false exits the loop completely, so in this

Now, I have a requirement to allow a database record to be edited along with a related collection/array (from another datastore) using this row editing plugin.
