问题描述
我是d3.js的新手，正在尝试执行d3示例中给出的一些示例代码.我尝试复制Text Transition-1(链接)示例代码.但是在控制台中遇到了此错误
I am new to d3.js and trying to execute some of the example codes given in the d3 examples. I tried copying the Text Transition-1 (link) example code. But came across this error in the console
text-transition.html:26未捕获的TypeError:
d3.select(...).transition(...).duration(...).on不是函数
text-transition.html:26 Uncaught TypeError:
d3.select(...).transition(...).duration(...).on is not a function
这是我执行的代码:
<!DOCTYPE html>
<html>
<head>
<title>Text Transition animation 1</title>
<meta charset="utf-8">
<style>
h1 {
font: 400 120px/500px "Helvetica Neue";
text-align: center;
width: 960px;
height: 500px;
margin: 0;
}
</style>
<script type="text/javascript" src="d3/d3.min.js"></script>
</head>
<body>
<h1>0</h1>
<script type="text/javascript">
console.log("the script is executing")
var format = d3.format(",d");
d3.select("h1")
.transition()
.duration(2500)
.on("start", function repeat() {
d3.active(this)
.tween("text", function() {
var that = d3.select(this),
i = d3.interpolateNumber(that.text().replace(/,/g, ""), Math.random() * 1e6);
return function(t) { that.text(format(i(t))); };
})
.transition()
.delay(1500)
.on("start", repeat);
});
</script>
</body>
</html>
我正在使用的d3js版本是3.5.17.在Google Chrome浏览器上执行代码段.
The d3js version I am using is 3.5.17. Executing the snippet on Google Chrome browser.

console.log("the script is executing")
var format = d3.format(",d");
d3.select("h1")
.transition()
.duration(2500)
.on("start", function repeat() {
d3.active(this)
.tween("text", function() {
var that = d3.select(this),
i = d3.interpolateNumber(that.text().replace(/,/g, ""), Math.random() * 1e6);
return function(t) {
that.text(format(i(t)));
};
})
.transition()
.delay(1500)
.on("start", repeat);
});
h1 {
font: 400 120px/500px"Helvetica Neue";
text-align: center;

margin: 0;
}
