You didn't ask a question, and you posted a whole bunch of code. Ask a specific question, and narrow your code down to the relevant parts, and someone may help.

Maq · April 24, 2012

salman, in the future, place

OR

tags around your code.

salman233 · April 28, 2012

hello

haku · April 29, 2012

1) Tell us what you have, what your current code is doing

2) Tell us what you want your code to do

3) Show us the code that you currently have that is causing you the problem

4) Give an example of what the desired output is

If you do these four things, it will be much easier to help you.

salman233 · April 30, 2012

var Country = new Array('Pakistan','USA');

// pakistan

Country['Pakistan'] = new Array('Punjab','Sindh');

Country['Pakistan']['Punjab'] = new Array('Faisalabad','Lahore','Multan');

Country['Pakistan']['Singh'] = new Array('Karachi');

// USA

Country['USA'] = new Array('New York');

Country['USA']['New York'] = new Array('New York','New York2');

var State = Country[value][value];

for(i=0; i<State.length; i++)

{

document.write(State);

}

this code displays nothing i want to display multidimensional array using for loop but it displays nothing

Jessica · April 30, 2012

How? You never answered any of my questions, and it's impossible to know what you are trying to do.

salman233 · May 2, 2012

haku · May 6, 2012

So am I:

1) Tell us what you have, what your current code is doing

2) Tell us what you want your code to do

3) Show us the code that you currently have that is causing you the problem

4) Give an example of what the desired output is

If you do these four things, it will be much easier to help you.

This thread is brilliant. Also, I'm sorry mate, I've tried going through your code but it is pretty unfathomable. Although I think you may be wanting to use an object instead of an array:

var country = {
  'Pakistan' : {
    'Punjab' : ['Faisalabad','Lahore','Multan'],
    'Sindh' : ['Karachi']
  },
  'USA' : {
    'New York': ['New York','New York2']
  }
};
