Question

I have an ExtJS xtemplate that is throwing errors because of the way a json object is returned.

Sometimes the json object has a field customer defined, but sometimes it’s completely missing from the object.

Obviously, I get an error customer is not defined when applying my template to the json where the field is missing.

So my question is:
Is there a way that I can check for an undefined field in an xtemplate?

Like:

<tpl if="customer!=undefined">{customer}</tpl>

obviously I’ve tried this but it doesn’t work.

Thanks for any help.

Answer 1

Have you tried this?

<tpl if="customer == undefined">
    <b>{customer}</b>
</tpl>
