How to convert string to variable name in Javascript

If you need to create a variable dynamically on the server side and retrieve the value on the client side, use the next example to use the value assigned:

// Declare the variable name

var myStringName = "echoHello";

// Assign a value to the dynamic string variable

window[myStringName] = "Hello from dynamic string variable!";

// Show value

alert(window[myStringName]);

// Or call the variable name

alert(echoHello);

You can even assign a function to the dynamic string variable:

// Declare the variable name

var myStringName = "alertStringVariable";

// Assign a function to the dynamic variable

window[myStringName] = function () {

    alert("Hello from dynamic function variable...");

}

// Execute the function assigned of the variable

alertStringVariable();
