Convert string to variable name in JavaScript
I’ve looked for solutions, but couldn’t find any that work.
I have a variable called onlyVideo.
"onlyVideo" the string gets passed into a function. I want to set the variable onlyVideo inside the function as something. How can I do that?
(There are a number of variables that could be called into the function, so I need it to work dynamically, not hard coded if statements.)
Edit: There’s probably a better way of doing what you’re attempting to do. I asked this early on in my JavaScript adventure. Check out how JavaScript objects work.
A simple intro:
// create JavaScript object
var obj = { "key1": 1 };
// assign - set "key2" to 2
obj.key2 = 2;
// read values
obj.key1 === 1;
obj.key2 === 2;
// read values with a string, same result as above
// but works with special characters and spaces
// and of course variables
obj["key1"] === 1;
obj["key2"] === 2;
// read with a variable
var key1Str = "key1";
obj[key1Str] === 1;
Answer
If it's a global variable then window[variableName]
or in your case window["onlyVideo"] should do the trick.
