悬停时的jQuery工具提示 [英] jQuery tool tip on hover

问题描述

我需要一个非常轻量级的工具提示，类似于此处的 http://www.history.com /视频当您将视频链接悬停在热门视频下时，工具提示会逐渐消失，它会停留在那里，您甚至可以选择文本，直到您将光标移开。当您将鼠标悬停在标记上时，Facebook和Google+也有类似的样式工具提示以及堆栈溢出。有人可以提供轻量级的方法来做到这一点。

I am in need of a very lightweight tooltip similar to the 1 found here http://www.history.com/videos when you hover a video link under "Popular Videos", a tooltip fades into place, it stays there and you can even select text on it until you move the cursor off it. Facebook and Google+ also have a similar style tool-tip as well as stackoverflow when you hover over a tag. Can someone provide a light weight method of doing this.

我有搜索并查看了许多现有的插件，但它们都有些臃肿。感谢您的帮助

I have search and looked at many existing "plugins" they are all somewhat bloated though. Thanks for any help

推荐答案

以下是一种非常简单的方法：

Here's a pretty simple way you could accomplish this:

var timeout;

function hide() {
    timeout = setTimeout(function () {
        $("#tooltip").hide('fast');
    }, 500);
};

$("#tip").mouseover(function () {
    clearTimeout(timeout);
    $("#tooltip").stop().show('fast');
}).mouseout(hide);

$("#tooltip").mouseover(function () {
    clearTimeout(timeout);
}).mouseout(hide);

其中 #tip 是你想要的元素鼠标悬停以显示工具提示， #tooltip 是实际的工具提示元素。

Where #tip is the element you want to mouseover to make the tooltip appear, and #tooltip is the actual tooltip element.

这是一个例子：< a href =http://jsfiddle.net/pvyhY/> http://jsfiddle.net/pvyhY/

如果你想把它包装在一个jQuery插件中：

If you wanted to wrap this in a jQuery plugin:

(function($) {
    $.fn.tooltip = function(tooltipEl) {
        var $tooltipEl = $(tooltipEl);
        return this.each(function() {
            var $this = $(this);            
            var hide = function () {
                var timeout = setTimeout(function () {
                    $tooltipEl.hide();
                }, 500);

                $this.data("tooltip.timeout", timeout);
            };

            /* Bind an event handler to 'hover' (mouseover/mouseout): */
            $this.hover(function () {
                clearTimeout($this.data("tooltip.timeout"));
                $tooltipEl.show();
            }, hide);

            /* If the user is hovering over the tooltip div, cancel the timeout: */
            $tooltipEl.hover(function () {
                clearTimeout($this.data("tooltip.timeout"));
            }, hide);            
        });
    };
})(jQuery);

用法：

$(document).ready(function() {
    $("#tip").tooltip("#tooltip");
});

添加更多功能，最终你会得到优秀的qTip插件，我建议也看一下。

Add more functionality and you'll eventually end up with the excellent qTip plugin, which I recommend taking a look at as well.
