Get object by name as string without eval

rated 0 times [ 193] [ 5] / answers: 1 / hits: 37897 / 12 Years ago, sun, august 12, 2012, 12:00:00

The code below does what I want, but I would like to avoid eval. Is there a function in Javascript that looks up an object by its name as defined by in a string?

myobject = {foo : bar}

myname = myobject;

eval(myname);

Some context: I am using this for an application in which a large number of nodes in the dom has a html5 data-object attribute, which is used in the handler function to connect back to the model.

Edit: myobject is neither global nor local, it is defined in one of the parent frames of the handler.

If variables are global then:

myobject = {foo : bar};

myname = myobject;

window[myname].foo

DEMO

For local:

(function(){

    myobject = {foo : bar};

    myname = myobject;

    alert( this[myname].foo );

})();
