问题描述
我想知道是否有可能为d3.js在定义的实际正文中的鼠标悬停事件而不是在页面顶部显示d3.js显示的工具提示功能的 CSS 样式.样式部分.
I'm wondering if its possible to define a CSS style for a tooltip function displayed by d3.js on mouse over event in the actual body of the definition rather than on top of the page in the style section.
JAVASCRIPT:
var tooltip = d3.select("#scatter-load").append("div")
.attr("class", "tooltip")
//.attr("position", "absolute")
//.attr("width", "200px")
//.attr("height", "30px")
//.attr("pointer-events", "none")
.style("opacity", 0);
chocolateGroup.append("circle")
.attr("r", function(d) {return rScale(d.size);})
.attr("opacity", 0.7)
.style("fill", "steelblue")
.on("mouseover", function(d) {
tooltip.transition()
.duration(200)
.style("opacity", .9)
tooltip.html(d.manufacturer + "<br/> (" + xValue(d)
+ ", " + yValue(d) + ")")
.style("left", (d3.event.pageX + 5) + "px")
.style("top", (d3.event.pageY - 28) + "px");
})
.on("mouseout", function(d) {
tooltip.transition()
.duration(500)
.style("opacity", 0);
});
CSS:
.tooltip {
position: absolute;
width: 200px;
height: 28px;
pointer-events: none;
我要寻找的是与这种样式类似的东西,其中在创建对象(例如填充)时定义CSS样式:
What I am looking for is something similar to this style where CSS styling is defined when object is created (for example fill):
svg.append("path")
.datum(data)
.attr("d", area)
.attr("fill", "steelblue");
