出于某种原因,我将js代码包装在一个立即调用的函数表达式中,我得到了progressBar not defined.想知道为什么会这样吗？

(function(){
    "use strict"

    var progressBar = function(){
        var bar = document.getElementById('pbar'),
        status = document.getElementById('status'),
        barValue = bar.value;

        status.innerHTML = barValue + "%";
        bar.value++;

        var increment = setTimeout("progressBar()", 50);
        if(bar.value == 100){
            status.innerHTML = '100% - Straight Besting';
            bar.value = '100';
            clearTimeout(increment);
        }
    }

    progressBar();

})()
