我正在尝试应用this的建议,以期结束几次过渡。
但是在我的本地文件中,出现Uncaught TypeError: t.call is not a function
错误。代码如下:
var svg = d3.select('svg');
function endall(transition, callback) {
if (typeof callback !== "function") throw new Error("Wrong callback in endall");
if (transition.size() === 0) { callback() }
var n = 0;
transition
.each(function() { ++n; })
.each("end", function() { if (!--n) callback.apply(this, arguments); });
}
for (var i=0;i<5;i++) {
svg.append('rect')
.attr("x",i*60)
.attr("y",50)
.attr("height",50)
.attr("width",50)
.style("fill","#ff0000");
}
svg.selectAll("rect:not(.active)")
.transition()
.duration(1000)
.style("fill","#00ff00")
.call(endall, function() { alert("all done") });
当我使用D3模板将其移植到jsfiddle上时,效果很好。另一方面,当我将其移植到没有D3模板的jsfiddle上时,也会遇到相同的错误。
很明显我遗漏了一些东西,但是我不明白什么。

不会产生错误的提琴在v3上运行,而不会产生错误的提琴在v5上运行。
在d3v3中,您可以将<tr style="background-color: #F7F6F3">
<html>
<head>
<title></title>
</head>

用于事件:
transition.each([type,] listener)
如果指定了type,则为过渡事件添加一个侦听器, 支持“开始”,“结束”和“中断”事件。听众将 为过渡中的每个单独元素调用。 (v3 docs)
在d3v4和v5中,对于事件,此方法已替换为transition.each("end",...)
:
selection.on(typenames [,listener [,options]])<>
为指定的每个选定元素添加或删除侦听器 事件类型名称。 (current docs)
transition.on("end",...)
仍可用于对要转换的每个项目执行操作,但不能用于事件监听。由于版本之间的更改,您会得到一个错误,它是t.call不是函数(它是一个字符串:transition.each(function)
),并且警报从不触发。
对于d3v4或d3v5,请改用:
"end"
