我前段时间开发了一个图表并且工作正常。最近我注意到Firefox中的工具提示不再有效(尽管它在Safari中正常工作)(两者都在Mac OS上)。任何人都可以建议可能导致问题的原因吗?
该图表嵌入在http://www.climateactionnow.ca/cumulative-manmade-emissions-1854-2010
的Drupal网站中更新:自发布此消息后,我发现了许多使用Firefox的错误报告......但尚未找到解决方案。
代码是:
<script>
var w = 450,
h = 500,
r = Math.min(w, h) / 2,
color = d3.scale.category20c();
function prettyAlert(p_message, p_title) {
p_title = p_title || "";
$(p_message).dialog({
title: p_title,
width:400,
height:400,
resizable: false,
modal : true,
overlay: {
backgroundColor: "#000", opacity: 0.5
},
close: function(ev, ui) {
$(this).remove();
}
});
}
hoverover=d3.select("body")
.append("div")
.attr("class","arcs-hoverover")
.style("display","none")
.style("position","absolute");
var svg = d3.select("#chart").append("svg:svg")
.attr("width", w)
.attr("height", h)
.append("svg:g")
.attr("transform", "translate(" + w / 2 + "," + h / 2 + ")");
var partition = d3.layout.partition()
.sort(null)
.size([2 * Math.PI, r * r])
.children(function(d) { return isNaN(d.value) ? d3.entries(d.value) : null; })
.value(function(d) { return d.value; });
var arc = d3.svg.arc()
.startAngle(function(d) { return d.x; })

.attr("d", arc)
.attr("fill", function(d) {

};

// Distort the specified node to 80% of its parent.
function magnify(node) {

}

.duration(750)
.attrTween("d", arcTween);
}; // end magnify
// Recursively reposition the node at position x with scale k.
function reposition(node, x, k) {
node.x = x;
if (node.children && (n = node.children.length)) {
var i = -1, n;
while (++i < n) x += reposition(node.children[i], x, k);
}
return node.dx = node.value * k;
}; // end reposition
// Stash the old values for transition.
function stash(d) {

d.dx0 = d.dx;
}; // end stash
// Interpolate the arcs in data space.
function arcTween(a) {
var i = d3.interpolate({x: a.x0, dx: a.dx0}, a);
return function(t) {

原因是在FF显示工具提示div
时,鼠标事件mouseout
会被触发,因此它会获得display:none
。
因此,工具提示不可见。
所以解决方法是让工具提示div不接受任何鼠标事件。
使用pointer-events:none
阅读here
所以在你的CSS里面添加:
.arcs-hoverover{
pointer-events:none
}
或者在代码中添加以下内容:
d3.selectAll(".arcs-hoverover").style("pointer-events", "none");
希望这有帮助!

当光标移动时,工具提示的定位导致鼠标移出事件。您可以改变顶部和左侧的距离(在您的代码中:-300和-20),这样光标就不能悬停在工具提示上。
// This snippet hides the system bars.
private void hideSystemUI() {
// Set the IMMERSIVE flag.
// Set the content to appear under the system bars so that the content
// doesn't resize when the system bars hide and show.
mDecorView.setSystemUiVisibility(
View.SYSTEM_UI_FLAG_LAYOUT_STABLE
| View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
| View.SYSTEM_UI_FLAG_HIDE_NAVIGATION // hide nav bar
| View.SYSTEM_UI_FLAG_FULLSCREEN // hide status bar
| View.SYSTEM_UI_FLAG_IMMERSIVE);
}
// This snippet shows the system bars. It does this by removing all the flags
// except for the ones that make the content appear under the system bars.
private void showSystemUI() {
mDecorView.setSystemUiVisibility(
View.SYSTEM_UI_FLAG_LAYOUT_STABLE
| View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN);
}

我有一个D3 v4散点图。我的工具提示在Chrome,Edge和IE中运行良好;但不适用于Firefox。在Firefox中,针对图表中左下角的数据点正确显示了工具提示,但仍处于隐藏状态,而未针对右上角的数据点显示。令人困惑。
当我遵循西里尔·谢里安(Cyril Cherian)的建议在相关CSS中添加“指针事件:无”时,该问题在Firefox中得以解决,而没有破坏Chrome,Edge或IE。
.tooltip {
position: absolute;
z-index: 10;
visibility: hidden;
pointer-events: none; /* <======= added code ====== */
background-color: lightblue;
text-align: center;
padding: 4px;
border-radius: 4px;
font-weight: bold;
color: black;
}
当我看到Chris Williams的示例使用“指针事件:无”并且在我尝试过的所有浏览器中都有效时,我采用了Cherian的解决方案。 D3 scatterchart with tooltips and pointer-events: none
