jQuery - 点击父元素（而不是父母子项）时淡出？ [英] jQuery - fade out when clicking on parent element (and not the parents children)?

问题描述

我在我的页面上有以下代码，我想做的是，当用户点击#loginBox之外，我想要整个#loginOverlay褪色。但我不能实现这种效果，没有通过点击#loginBox ...触发fadeout

I've got the following code on my page, and what i'm trying to do is that when a user clicks outside the #loginBox, i want the entire #loginOverlay to fadeout. But i can't achieve this effect without having the fadeout triggered by clicking on #loginBox...

它放置在页面的底部，我有一个链接在触发淡入淡出的页面上。

It's placed on the bottom of the page, and i have a link on the page that triggers the fadein. But the fadeout is a bit struggling now tbh.

我试过这样做：

$("#loginOverlay").click(function() { ...fadeout... });

但它给了我相同的结果。

but it gives me the same result.

那么任何建议？提前感谢！

So any suggestions? Thanks in advance!

<div id="loginOverlay">
    <div id="loginBox">
        <img class="closeBtn" src="images/icons/close.png" alt="" />
        <h3>Login</h3>
        <form action="login.php?ref=index.php" method="post">
            <input type="text" name="username" value="Username..." onblur="if(this.value.length == 0) this.value='Username...';" onclick="if(this.value == 'Username...') this.value='';" />
            <input type="password" name="password" value="Password..." onblur="if(this.value.length == 0) this.value='Password...';" onclick="if(this.value == 'Password...') this.value='';" />
            <input class="loginBtn" type="submit" name="submit" value="Login!" />
        </form>
    </div> <!--login box -->
</div>



<script src="js/jquery-1.4.2.min.js"></script>
<script>
$(document).ready(function() {
    $('#loginOverlay').css('display', 'none');

    $('#loginToggle').click(function() {
        $("#loginOverlay").fadeIn(200);
    });

    $("#loginBox").parent().click(function(){
        $("#loginOverlay").fadeOut(100);
    });

});

推荐答案

您需要检查 e .target 查看实际点击的元素：

You need to check e.target to see what element was actually clicked:

$("#loginOverlay").click(function(e) {
    if (e.target === this)
        $("#loginOverlay").fadeOut(100);
});
