对D3来说非常新,而且一般来说对JS来说相对较新。我试图在点击上创建一个圆圈,一旦创建该圆圈需要反复脉动。现在,它正在被正确创建并且它进行了一次转换,但是由于错误它会死掉。这是我的代码:
position
我在Chrome中运行时收到的错误是:
var shapesAtt = shapes
// omitted: assigning fill, position, etc; working as intended
.on("click", circleMouseClick);
function circleMouseClick(d, i)
{
createPulse(this);
}
function createPulse(focusElement)
{
// takes in "focal circle" element
// some things here are hard coded for ease of reading
// (i.e. these variables aren't all useless)
var focus = d3.select(focusElement);
var origR = focus.attr("r");
var origX = focus.attr("cx");
var origY = focus.attr("cy");
var origFill = focus.style("fill");
var strokeColor = "black";
var newG = svgContainer.append("g");
var pulser = newG.append("circle").attr("id", "pulser")
.style("fill", "none").style("stroke", strokeColor)
.attr("cx", 150).attr("cy", 150)
.attr("r", origR)
.transition()
.duration(2000)
.each(pulsate);
}
function pulsate()
{
var pulser = d3.select(this);
pulser = pulser
.transition().duration(2000)
.attr("r", 25)
.attr("stroke-width", 50)
.transition().duration(2000)
.attr("r", 90)
.attr("stroke-width", 10)
.each("end", pulsate);
}
我认为它的代码部分是:
Uncaught TypeError: t.call is not a function d3.v4.min.js:4
答案 0 :(得分:36)
这是因为您使用的是d3版本4。 v4 API发生了重大变化,因此:
而不是使用
// ...
.each("end", pulsate);//in d3 version 3
做
// ...
.on("end", pulsate);//in d3 version 4
