无法通过JavaScript访问变量-范围错误？

Question

I have some data in a separate .js file similar to this:

data = new Object();
data['cat'] = ['Mr. Whiskers','Wobbles'];
data['dog'] = ['Toothy'];
data['fish'] = ['goldy','roose'];

function getStuff(info)
{
  var stuff = data[info.value];
  return stuff;
}

Now in another html file with a block, I have something like this:

function theDrop(dynamic) {
  alert(getStuff(dynamic));
}

The box says undefined , why?

Answer 1

What are you passing to theDrop ? If you want to call the .value then you need to pass the whole object over otherwise you will get undefined

Live Demo

var select = document.getElementById("selectme");

select.onchange = function(){
    theDrop(this);
}

data = new Object();
data['cat'] = ['Mr. Whiskers','Wobbles'];
data['dog'] = ['Toothy'];
data['fish'] = ['goldy','roose'];

function getStuff(info)
{
    var stuff = data[info.value];
    return stuff;
}

function theDrop(dynamic) {
    alert(getStuff(dynamic));
}
