javascript - onBlur() 无法正常工作

Question

我想要 <div>与类 .shell-pop如果他们点击元素区域之外，将被关闭。但是它似乎没有触发，并且也没有日志或警报消失。我环顾四周，似乎一切正常？

jQuery

$('document').ready(function () {
    updateCart();

    $(".shell").click(function (e) {
        e.preventDefault();
        $(".shell-pop").fadeIn(300, function () { $(this).focus(); });
    });

    $(".shell-pop").on('blur', function () {
        $(this).fadeOut(300);
        window.alert("work");
        console.log("works");
    });
});

HTML

<div class="options-area">
    <div class="options-popup shell-pop">
        <div class="swatches">
            <div class="colors-shell colors" id="green">
                <p class="prices-for-swatch">$14.23</p>
            </div>
            <div class="colors-shell colors" id="pink">
                <p class="prices-for-swatch">$7.23</p>
            </div>
            <div class="colors-shell colors" id="blue">
                <p class="prices-for-swatch">$11.25</p>
            </div>
            <div class="colors-shell colors" id="orange">
                <p class="prices-for-swatch">$10.23</p>
            </div>
            <div class="colors-shell colors" id="default-shell">
                <p class="prices-for-swatch">FREE</p>
            </div>
            <div class="colors-shell colors" id="exit">
                <img src="img/Silhouette-x.png" class="x-logo" alt="exit" />
                <p class="closeit">CLOSE</p>
            </div>
            <div class="shell square">
                <img src="img/controllers.png" class="item-icon" alt="controller-piece">
                <p class="name-of-item">Shell</p>
                <p id="shell_Price1" class="items-price">0.00</p>
            </div>        

Answer 1

给出你的<div>一个tabindex .

The tabindex global attribute is an integer indicating if the element can take input focus (is focusable), if it should participate to sequential keyboard navigation, and if so, at what position.

注意以下...

<div tabindex="-1"></div>

$('div').on('blur', function() {
    console.log('blurrr');
});
