问题描述
如何在D3.js中连续运行转换?
How can I run a transition continuously in D3.js?
例如,我想更改正文
颜色从红色到蓝色,再回来,不断(我不,那将是可怕的,但与它一起去)。
For example, say I want to change the body
colour from red to blue and back again, continuously (I don't, that would be horrendous, but go with it).
这是我会做一次:
d3.select("body").transition().duration(1000).style("background-color", "red");
我如何连续做?
最近的例子我看到使用 d3.timer
,但我不知道如果有一个更好的方法来做到。
The closest examples I have seen use d3.timer
, but I am not sure if there is a better way to do it.
推荐答案
您可以使用 transition.each()
和结束事件。代码看起来像下面这样。
You can use transition.each()
and the "end" event. The code would look something like the following.
function myTrans() {
d3.select("body").transition().duration(1000).style("background-color", "red")
.each("end", function() {
d3.select(this).transition().duration(1000).style("background-color", "blue")
.each("end", function() { myTrans(); });
});
}
