javascript - Using variables in MongoDB update statement

Question

I am trying to use a variable as the field name in an update statement and it is not working at all, any suggestions?

for example:

COLLECTIONNAME.update(
    { _id: this._id },
    { $set: { VARIABLE1 : VARIABLE2 } }
);

actual code:

 'blur .editable' : function () {
      var target = event.currentTarget.value;
      var field = event.currentTarget.name;
      field = ' " ' + field + ' " ';
      Hostings.update( { _id: this._id },{ $set: { field : target } } );
    }

Answer 1

You can do it this way:

'blur .editable' : function () {
  var target = event.currentTarget.value;
  var field = event.currentTarget.name;

  var obj = {};
      obj[field] = target;
  Hostings.update( { _id: this._id },{ $set: obj } );
}

Javascrip objects can be accessed two ways:

object.attribute

or

object["attribute"]

if you use the second method you can access it with a variable
