Setting a variable within an if statement - JQuery

I'm trying to set a variable within an if statement but for some reason it isn't working! I'm really bad with JQuery/Javascript, so I was hoping someone could help. Here's the code I'm working with:

if($("#myicon").hasClass('opacity0')) {
var variable = 1;
}

Any ideas? Thanks!

EDIT: I should add that I'm trying to use this along with charts.js to make a doughnut chart. So, for example

var doughnutData = [
        {
            value: variable,
            color:"#000000"
        }
    ];

If I manually say "value: 1," it works. But when I try to set it using a variable it doesn't create a chart.

The variable within the if statement just is used for itself(local variable).

You should declare this variable above the if statement.

var variable;

if($("#myicon").hasClass('opacity0')) {
    variable = 1;
}

var doughnutData = [
    {
        value: variable,
        color:"#000000"
    }
];

Hope it helpful!

Cheers.

If you're trying to access variable elsewhere in you code then just drop the var so that you're not declaring it on the local scope.

Global variables are not the ideal way to code but without seeing the rest of your code I can't suggest much more
