Guide on utilizing the eval() function to assign a value to a field passed as a parameter

I am interested in achieving the following:

function modifyField(fieldName){
    eval(fieldName) = 1234;
}

In simpler terms, I want to pass a specific field name as a parameter and then assign a value to that field. Can someone guide me on how to accomplish this?

Answer №1

To create a new variable with a dynamic variable name in the global scope, you can simply use the following code snippet:

function setVariableValue(variableName){
    window[variableName] = 1234;
}

It is not advisable to utilize the evil() function in your code.
