Javascript using variable as array name

rated 0 times [ 82] [ 6] / answers: 1 / hits: 18618 / 15 Years ago, thu, june 4, 2009, 12:00:00

I have several arrays in Javascripts, e.g.

a_array[0] = abc;

b_array[0] = bcd;

c_array[0] = cde;

I have a function which takes the array name.

function perform(array_name){

    array_name = eval(array_name);

    alert(array_name[0]);

}

perform(a_array);

perform(b_array);

perform(c_array);

Currently, I use eval() to do what I want.

Is there any method not to use eval() here?

You can either pass the array itself:

function perform(array) {

    alert(array[0]);

}

perform(a_array);

Or access it over this:

function perform(array_name) {

    alert(this[array_name][0]);

}

perform('a_array');
