jquery: use string as function (error: string is not a function)
This question already has an answer here:
It depends a bit on the scope, but the general idea is that you can use the square bracket notation to get a reference to the function and execute it. For example, the following:
window[value]();
would be equivalent to callme() for the first iteration, assuming the callme function is globally scoped (a property of the window object).
You could try using eval to evaluate the string as a function, although you have to be careful security-wise. Evaluating a string coming from user input or a form submission could make your site vulnerable to cross-site scripting and session hijacking.
Example:
eval(value + "();"); //call "value" as a function
