    get position of an array inside of another array

    I want to get an array position inside of another array, how can i do this?

    ex:
    var i=0;

    array1=['content','content2','content3'];
    array2=['content4','conten5'];

    var array=[
    array1,
    array2
    ];

    lets say I want array1 but the second spot in the array

    how would i go about using array[] getting that specific position?

    I think you need to give us a real example, rather than a dummy one.

    I strongly suspect that your third array (named array) is not the best choice of structure.

    Code:
    array[0][1]
    but I agree - if you describe what you are trying to do you will almost certainly get a suggestion for a better way to do it.

    Seems like what xelawho said, sounds like a 2-dimensional array:
    Code:
    <!DOCTYPE html>
    <html>
    <head>
    <script>
    var arr = [1,2,3];
    var arr2 = ['a','b','c'];
    
    var sample = new Array(arr,arr2);
    alert(sample[1][1]); //results with 'b'
    alert(sample[0][2]);//results with 3;
    
    </script>
    </head>
    <body>
    </body>
    </html>

    Yes, but my point (and Xelawho agrees) is that it's quite possible--and I think likely--that an array of arrays may not be the right way to go, depending on what he is trying to accomplish.

    I'm betting that a collection of arrays, for example, might be better.

    example:
    Code:
    var data = {
       "adam" : ['content','content2','content3'],
       "eve"  : ['content4','conten5']
    };
    Or perhaps even:
    Code:
    var people = {
       Adam : { gender : "Male", order : "First", lost : "A rib" },
       Eve  : { gender : "Female", temptedby : "Snake", order : "Second" }
    };
    Often, arrays are clumsy in comparison.


    But we won't know until/unless pdiddles posts again.
