Call javascript function which name is in variable [duplicate]

The problem is next: Assume that we have a select. Onchange event we need to call some function, but name of this function kept in variable. How to call this function ?

window[name]()

You can call functions by name reference by selecting them as a property of window and executing them

have you tried variableName(); ?

We often pass around callback functions, which might look something like this

function doSomething(callbackFunction){
    // some happy code
    callbackFunction()
}
