When using the quojs javascript library, I often come across statements like these:
return r(e,this[0].className)
or
return this[0].style[e]||n(this[0],e)
While I understand that this refers to the "global object," I am curious about the significance of the array. Does it represent properties of the global object?
The concept of this is influenced by various factors, making it impossible to determine its value based on a snippet of code alone.
For instance:
var person = {
name: "Bob",
sayHi: function() {
alert(this.name + " says hi!");
}
};
person.sayHi();
In the above example, this points to the object person when the sayHi() method is called. However, if only the following line was provided:
alert(this.name + " says hi!");
It would be unclear what value this holds. this represents the context, making the context of its usage significant!
