How to access a local object in a dictionary with JavaScript?

Question

I have nested object

var model = {
    weather: {
        allData: ""
    },

    woeid: {
        id: 2389646,
        searchText: "davis",
        woeidScript: "some string'"+searchText+"' another string",
        forcastScript: "",
        found: true
    }

};

searchText in woeidScript returns undefined. How can reference this local object?

You cannot access parts of an object in the middle of its object initializer block. You have to use a separate statement. — Pointy

searchText references the variable called that. In order to DRY, we would have to look at the code surrounding it. — yxre

You could use a getter:

The get syntax binds an object property to a function that will be called when that property is looked up.

An advantage is, you can assign other values to property valueA or valueB and get the actual result of the division.

-- And a direct reference to the object.

var model = {
    weather: {
        allData: ""
    },
    woeid: {
        id: 2389646,
        searchText: "davis",
        get woeidScript() { return "some string'" + model.woeid.searchText + "' another string"; },
        forcastScript: "",
        found: true
    }
};
document.write(model.woeid.woeidScript);
