Call different jQuery functions depending on suffix in their name

Question

I have 3 jQuery functions with indexed progressive name such as:

function foo_1()
{
   ...
}

function foo_2()
{
   ...
}

function foo_3()
{
   ...
}

I need to dynamically discern the functions as shown:

foo_[i]

The overall purpose is to call a different function depending on the value of i variable.

How should I do that?

try this for example:

var i = "3";
window["foo_" + i]();

Another way is using the plain Javascript method eval():

var index = 1;
eval("foo_"+index+"()");
