Question

Good day!

I am writing a script as follows:

var prev = 0;

$(document).ready(function(){
    dynamicListOne(length, prev);
});

function dynamicListOne(length, prev){
   length++;
   prev = length;
}

But prev is always 0.
How can i assign prev=length?

Thank you in advance

Answer 1

Your function takes prev as an argument so inside the function the name points to a local variable instead of the global one. Just don’t add it as an argument to your function.

And think carefully if you really really want a global variable.
