please help; 3 dimensional arrays 2
- Thread starter JeroenB
- Start date
Multidimensional arrays in javascript are just arrays of arrays:
x=new Array([0,1,'a',3,4],[0,1,2,3,4])
x[0][2] is 'a'
x[1][4] is 4
note that d=[0,1,2,3] is systematically equivalent to d=new Array(0,1,2,3) jared@eae.net -

Hi JeroenB,
here is an example of 3x3x3 array:
MyArray = new Array(3)
MyArray[0] = new Array(3)
MyArray[0][0] = new Array(3)
MyArray[0][0][0] = "something"
alert(MyArray[0][0][0])
hope this helps, Chiu Chan

yeh, thanks,
but another poblem is now that I have to make with this array a kind of 3dimensional <select>-tool;
for instance; if region1 is selected, I can choose between 10 countries; and if I then have selected a country and can choose between 10 cities ...

Place = new Array("North America","ASIA"
// Define Countries in Place[0] or North America
Place[0] = new Array("USA","CANADA"
// Define Cites in Place[0][0] or USA
Place[0][0] = new Array("NEW YORK","WASHINGTON","BOSTON"
// Alert Place[0][0][0] or New York
alert(Place[0][0][0])

PepperPepsi, thaks a lot for your help;
but I still have a problem (as I'm not a great expert in javaScript);
Once I've defined this array; how can I then do the following :
In my html page I have three <select> boxes; (this equals the three dimensions in my array). So once I have chosen a region, I can choose a country in the second one and the I can choose a city in the third...
But once I change back my region the other two <select> boxes should be resetted....so I can start over again...
Can You help me out...
Thanks in advance
JeroenB
