jQuery.each变量范围

Question

I have the following problem:

        var loader = new THREE.JSONLoader( true );
        model = JSON.parse(data);
        var modeldata = loader.parse( jQuery.parseJSON(model['value1']) );
        ...
        var modeldata = loader.parse( jQuery.parseJSON(model['value2']) );
        ...

WORKS FINE.

        var loader = new THREE.JSONLoader( true );
        model = JSON.parse(data);
        jQueryX.each(parts, function(key, value){
                var modeldata = loader.parse( jQuery.parseJSON(model[value]) );
                ...
        });

returns 'model is undefined'

Is there a scope problem? I can not see any...

Expert advices welcome...

Answer 1

I am not sure about this. parts contains the list of keys (in parts[value]) that are used in model. In other words, the key of model is the value of parts.

You need to just use jQuery.parseJSON(model[key])

 jQueryX.each(parts, function(key, value) {
      modelData = loader.parse(jQuery.parseJSON(model[key]));
 });

key is the key by which you get the value.
