javascript - 变量比较

Question

我在 Javascript 中遇到了一个简单的问题，我想比较两个变量，但不知何故它无法正常工作。我什至检查了变量的类型是否相同。请帮忙。 具体来说，我收到数字警报，甚至收到当前计数器为 5 总计为 5 的警报，尽管我希望它输入“然后”。

function fun(idCount, finalCallback) {
this.idCount = parseInt(idCount);
var counter = 0;
var strings = {};
this.register = function(str, id) {
    counter++;
    strings[parseInt(id)] = str;

    if(counter == this.idCount) {
        alert("Going to override");
        //blabla
    } else {
        alert("Current counter is: " + counter + " Total " + idCount + ". Types: " + typeof counter + " and " + typeof idCount);
    }
}
}

试试这个，

function fun(idCount, finalCallback) {
    var self = this;
    this.idCount = parseInt(idCount, 10);
    var counter = 0;
    var strings = {};
    this.register = function(str, id) {
        counter++;
        strings[parseInt(id, 10)] = str;

        if(counter == self.idCount) {
            alert("Going to override");
            //blabla
        } else {
            alert("Current counter is: " + counter + " Total " + idCount + ". Types: " + typeof counter + " and " + typeof idCount);
        }
    }
}
