我有一个如下的d3js条形图。我在每个栏上单击添加一个工具提示。我无法添加事件来关闭提示中的工具提示。有办法添加吗?
代码段如下:
var margin = {
top: 10,
right: 0,
bottom: 58,
left: 30
};
var width = 300 - margin.left - margin.right;
var height = 300 - margin.top - margin.bottom;
var barWidth = 40;
var graph;
var x;
var y;
var dataset;
var yTicks = 6;
var tooltipEl = function(d) {
return (
'<div class="tip__container">' +
'<div class="val">' +
d.val +
"</div>" +
'<div class="close">' +
"<button>×</button>" +
"</div>" +
"</div>"
);
};
dataset = [{
desc: "test1",
val: 40
},
{
desc: "some dummy text here",
val: 120
}
];
x = d3
.scaleBand()
.domain(
dataset.map(function(d) {
return d.desc;
})
)
.range([0, width]);
y = d3
.scaleLinear()
.range([height, 0])
.domain([0, 350]);

答案 0 :(得分:2)
由于div的HTML是通过bar的click函数的回调内的selection.html()
方法创建的,因此您必须在同一回调内设置侦听器:
div.select("button").on("click", function() {
div.style("opacity", 0)
});
这是您所做的更改的代码:
var margin = {
top: 10,
right: 0,
bottom: 58,
left: 30
};
var width = 300 - margin.left - margin.right;
var height = 300 - margin.top - margin.bottom;
var barWidth = 40;
var graph;
var x;
var y;
var dataset;
var yTicks = 6;
var tooltipEl = function(d) {
return (
'<div class="tip__container">' +
'<div class="val">' +
d.val +
"</div>" +
'<div class="close">' +
"<button>×</button>" +
"</div>" +
"</div>"
);
};
dataset = [{
desc: "test1",
val: 40
},
{
desc: "some dummy text here",
val: 120
}
];
x = d3
.scaleBand()
.domain(
dataset.map(function(d) {
return d.desc;
})
)
.range([0, width]);
y = d3
.scaleLinear()
.range([height, 0])
.domain([0, 350]);
graph = d3
.select("#graph")
.append("svg")
.attr("class", "bar-chart")
.attr("width", width + margin.left + margin.right)
.attr("height", height + margin.top + margin.bottom)
.append("g")
.attr("transform", "translate(" + margin.left + "," + margin.top + ")");
// Tool Tip
