Question

var test1;
$(document).ready(function () {
    test1 = $("#test1ID").jQueryPlugin();
});

var test2;
$(document).ready(function () {
    test2 = $("#test2ID").jQueryPlugin();
});

...

This is done so we could just do test1.foo()… foo is a function inside the jQueryPlugin that is accessible using test1.foo() syntax;

So we have an array of strings which contains (test1, test2, …)
and we need to access foo() while on the loop:

for(i=0; i < theArrayOfStrings.length; i++){
    theArrayOfStrings[i].foo();
    //so here is the problem... we can't do test1.foo(), test2.foo() ... =(
}

Any idea on how to call function foo() while on the loop?
Or can we convert a string value to a variable in javascript?

Answer 1

eval() function is used to evaluate script in a string variable. For example :

var test1;
eval("test1=" + theArrayOfStrings[i]);
test1.foo();

But take a lok at this question before use When is JavaScript’s eval() not evil?
