将弹出/信息提示/工具提示显示为悬停特定文本

Question

我有一张图表， http://codepen.io/Siddharth11/pen/LVQmjN

当我将鼠标悬停在上图右侧的颜色代码上时，我想显示一个弹出窗口。

我将为每个颜色代码显示单独的信息。那么我们如何为每个颜色代码创建单独的弹出窗口。

类似于莫里斯地图：http://codepen.io/andreic/pen/CJoze

或者这个：http://codepen.io/anon/pen/woJMrX

这个问题还没有得到任何正确的响应。我尝试使用 jquery 插件（漂亮的提示）并尝试解决这个问题。但没有运气。我已经重新发布了这个问题并取得了进展。请参考链接对于当前情况，代码：jquery plugin to bind data to a tool-tip (poshy tip)

Answer 1

这对于 SO 来说可能过于宽泛，但这是我喜欢在没有任何外部库或插件的情况下创建工具提示的方式。它基于创建<div>，我们将使用“不透明度”显示/隐藏它。

首先，设置工具提示的 CSS 样式，使用具有名为“工具提示”的类或任何其他名称的 div：

div.tooltip {   
    position: absolute;         
    /*your other styles here*/;              
}

然后，设置一个工具提示变量：

var tooltip = d3.select("body").append("div") 
    .attr("class", "tooltip")               
    .style("opacity", 0);

这个 div 的不透明度为 0。然后只需在mouseover 或mousemove 上显示工具提示即可：

text.on("mousemove", function(d) {
    tooltip.html("Hello, I am<br>a tooltip!")
        .style('top', d3.event.pageY - 6 + 'px')
        .style('left', d3.event.pageX + 10 + 'px')
        .style("opacity", 1);
    }).on("mouseout", function(d) {
        tooltip.style("opacity", 0);
    });

您可以使用 HTML 标记为工具提示中的文本设置样式，使其变为粗体、斜体等。
