Jquery 带有函数的 JavaScript 三元运算符示例

I am using jQuery 1.7.1

I am just starting to use the JavaScript ternary operator to replace simple if/else statements. I have done so successfully in several places. I was surprised when I successfully made something else work when I thought for sure it wouldn't, but I tried anyway.

以下是原始声明:

function updateItem() {
    $this = $(this);
    var IsChecked = $this.hasClass("IsChecked");
    if (IsChecked == true){
        removeItem($this);
    } else {
        addItem($this);
    }
}

Here's the same function using the ternary operator:

function updateItem() {
    $this = $(this);
    var IsChecked = $this.hasClass("IsChecked");
    (IsChecked == true) ? removeItem($this) : addItem($this);
}

I was surprised because all of the examples I saw being used were merely setting variables like this:

x = (1 < 2) ? true : false;

我的问题是，这是否是"正常"使用，在大多数版本的JavaScript中是否有效？它会在哪里失败？它还有其他不太明显的用途吗？

UPDATE -- Thanks for the "real world" advice!!!

我将此函数用作我的函数:

function updateItem() {
    $this = $(this);
    $this.hasClass("IsChecked") ? removeItem($this) : addItem($this);
}
