The array of Javascript arrays, both an array and a dictionary (Dictionary). Let's take a look at the use of arrays.
Copy Code code as follows:
var a = new Array ();
A[0] = "Acer";
A[1] = "Dell";
for (var i = 0; i Alert (A[i]);
}
Next look at the use of the dictionary.
Copy Code code as follows:
var computer_price = new Array ();
computer_price["Acer"] = 500;

The array of Javascript arrays, both an array and a dictionary (Dictionary).
Let's take a look at the use of arrays.
Copy Code code as follows:
var a = new Array ();
A[0] = "Acer";
A[1] = "Dell";
for (var i in a) {
alert (i);
}
The code above creates an array with each element being a string object.
The array is then traversed. Note that the result of I is 0 and 1,a[i] is a string.
This is much like the propertie
