Backbone.js fetch with parameters

Question

changing:

collection.fetch({ data: { page: 1} });

to:

collection.fetch({ data: $.param({ page: 1}) });

So with out over doing it, this is called with your {data: {page:1}} object as options

Backbone.sync = function(method, model, options) {
    var type = methodMap[method];

    // Default JSON-request options.
    var params = _.extend({
      type:         type,
      dataType:     'json',
      processData:  false
    }, options);

    // Ensure that we have a URL.
    if (!params.url) {
      params.url = getUrl(model) || urlError();
    }

    // Ensure that we have the appropriate request data.
    if (!params.data && model && (method == 'create' || method == 'update')) {
      params.contentType = 'application/json';
      params.data = JSON.stringify(model.toJSON());
    }

    // For older servers, emulate JSON by encoding the request into an HTML-form.
    if (Backbone.emulateJSON) {
      params.contentType = 'application/x-www-form-urlencoded';
      params.processData = true;
      params.data        = params.data ? {model : params.data} : {};
    }

    // For older servers, emulate HTTP by mimicking the HTTP method with `_method`
    // And an `X-HTTP-Method-Override` header.
    if (Backbone.emulateHTTP) {
      if (type === 'PUT' || type === 'DELETE') {
        if (Backbone.emulateJSON) params.data._method = type;
        params.type = 'POST';
        params.beforeSend = function(xhr) {
          xhr.setRequestHeader('X-HTTP-Method-Override', type);
        };
      }
    }

    // Make the request.
    return $.ajax(params);
};

So it sends the 'data' to jQuery.ajax which will do its best to append whatever params.data is to the URL.

You can also set processData to true:

collection.fetch({ 
    data: { page: 1 },
    processData: true
});

Jquery will auto process data object into param string,

but in Backbone.sync function, Backbone turn the processData off because Backbone will use other method to process data in POST,UPDATE...

in Backbone source:

if (params.type !== 'GET' && !Backbone.emulateJSON) {
    params.processData = false;
}

Another example if you are using Titanium Alloy:

 collection.fetch({ 
     data: {
             where : JSON.stringify({
                page: 1
             })
           } 
      });
