Javascript工具提示仅在第二次悬停时出现 [英] Javascript tooltip only appears on second hover
问题描述
我正在使用jQuery和Twitter Bootstrap,并想要工具提示将鼠标悬停在链接上时显示但是,当我第一次将鼠标悬停在链接上时,工具提示不会显示,但如果我将鼠标移开并重新打开,则每次都会对该链接起作用。
I am using jQuery and Twitter Bootstrap, and want to have a tooltip appear when hovering over a link. However, the tooltip doesn't appear the first time I hover over a link, but if I move the mouse away and back on, it works every time for that link.
我在页面上有几个:
<a href="#" onmouseover="$(this).tooltip();" class="postAuthor" data-original-title="@username">Full Name</a>
我创建了一个jsFiddle来演示: jsFiddle 。任何帮助将不胜感激 - 提前感谢!

推荐答案
正在发生的事情是你在元素上实例化插件当你第一次鼠标悬停它,然后插件在该元素的后续鼠标悬停时按预期工作。
What's happening is that you're instantiating the plug-in on the element when you mouseover it the first time, and then the plug-in works as expected on subsequent mouseovers on that element.
使用中建议的配置docs 有效(参见小提琴):
JavaScript:
// tooltip demo
$('div').tooltip({
selector: "a[data-toggle=tooltip]"
})
HTML:
<div style="text-align: center; width: 100%; margin-top: 50px;">
<a href="#" data-toggle="tooltip" class="postAuthor" data-original-title="@username">Full Name</a> <p/><p/>
<a href="#" data-toggle="tooltip" class="postAuthor" data-original-title="@username">Full Name</a><p/>
<a href="#" data-toggle="tooltip" class="postAuthor" data-original-title="@username">Full Name</a><p/>
<a href="#" data-toggle="tooltip" class="postAuthor" data-original-title="@username">Full Name</a><p/>
<a href="#" data-toggle="tooltip" class="postAuthor" data-original-title="@username">Full Name</a>
</div>
