函数中的Javascript数组创建

Question

I'm not very familiar with Javascript and have come across something that I can't find an answer to so far, looking at the following code:

function gridWindow(visible) {
    this.name='grid';
    this.visible=visible;
    this.defn={ gridText: ['aString1', 11], gridProp: ['aString2', 1], gridTime: ['aString3', 4] };
    this.init();
}

My question is what is happening with this line from above:

this.defn={ gridText: ['aString1', 11], gridProp: ['aString2', 1], gridTime: ['aString3', 4] };

Is it creating an array? What do the numbers mean after each string (the 11, 1 and 4)? How would I retrieve a value from this kind of array?

Thanks.

Answer 1

In this line :

this.defn={ gridText: ['aString1', 11], gridProp: ['aString2', 1], gridTime: ['aString3', 4] };

this.defn is a json object which contains keys :

gridText , gridProp , gridTime

These keys are json Arrays with two values in it .

If you want to get values of gridText , you can get it like this :

this.defn.gridText[0] // it will return 'aString1'
this.defn.gridText[1] // it will return 11

Answer 2

its not array, it is and object with key value pairs and values are arrays

you can get the value as this.defn.gridText . This will return you array ['aString1', 11]
