Question

Hello it is possible to access the value of a JavaScript variable by name? Example:

var MyVariable = "Value of variable";


function readValue(name) {
     ....
}


alert(readValue("MyVariable"));

Is this possible, so that the output is “Value of variable”? If yes, how do I write this function?

Thanks

Global variables are defined on the window object, so you can use:

var MyVariable = "Value of variable";
alert(window["MyVariable"]);
