data-if-XXX == "null" doesn't work

[ErnestoLopez]

I can't draw template only if XXX field is null or is not null.

I've tried with next code:

<.... data-if-XXX = "null">
<.... data-if-XXX = 'null'>
<.... data-if-XXX = null>
<.... data-if-XXX = "'null'">
<.... data-if-XXX = "">
....

and negative options
<.... data-if-XXX != "null">
....

but nothing.

I really appreciate any help you can provide.

You can try data-has:

<li data-template data-has="friend">{{friend}}></li>

Field exists, but have null value.
I want avoid to draw rows that a particular field is null

thanks a lot.

I see - in the latest version of Tempo on the master branch you can now check for null with data-if-:

<li data-template data-if-type="null">I am a nothing: {{name}}</li>

Let me know if that works for you - thanks for reporting!

latest versión of Tempo on the Master Branch

¿2.1?

doesn't Works for me with same call I did with Tempo 2.0

if I change 358 line adding

                } else if (attr.value === 'null') {
                    val = null;

in 2.0 versión works fine

   null equal comparations 

but doesn't work

   null not equal comparations

I will be watching next versions until it woks.

Meanwhile I'm doing this conditions in SQLite querys.

Regards,

Ernesto.

I'm not sure what you're suggesting here. Ideally you do this in the model/data layer.

Originally I wanted filter JSon data, hidding those rows that had a null field using Tempo.

But I can't, thus I will rewrite the way I obtain JSon data through sql query.

Thanks a lot for this great job, I will use Tempo and will be alert for every changes.

Strange this should work just fine now. Can you paste in some example JSON?

[ErnestoLopez]

Here is the code:

http://jsfiddle.net/BmkC8/

it works fine but

• When I update my own code (phonegap + jquery + jquerymobile +....) with tempo.js to 2.1 tempo doesn´t work.
• In the other hand, how can I configure tempo to show rows where a particular field <> null

Regards.

[mrolafsson]

The jsfiddle does not have a reference to Tempo so doesn't work - I will have a look at that. I can't tell you why your application doesn't work without seeing any debug information.

[mrolafsson]

This seems to work fine? http://jsfiddle.net/BmkC8/3/

To check for not null you would either have to use some other method of checking or we would have to add data-if-not support.
