问题描述
是否可以在转换期间将事件绑定到选择?
Is it possible to bind an event to a selection during a transition?
例如,假设这是您的更新:
For example, let's say this is your update:
g3.selectAll(".circles")
.data(dataFiltered, function(d){ return d['token']})
.transition().delay(circleDelay).duration(1200)
.attr('r', pointRadius + "px")
.attr('stroke', '#fff')
.attr('stroke-width', 1.5)
.attr("fill",function(d,i){ return (typeof(d[3]) === 'string') ? colorize(d[3]) : null })
.style('cursor',"pointer")
.attr('class',"circles");
它会引发一个错误链接 .on('mouseover',function mouseoverlogic (){});
It throws an error to chain .on('mouseover',function mouseoverlogic(){});
在 c $ c> pattern,可以在
exit()
?
推荐答案
由于转换是一种特殊类型的选择,因此不能使用转换中所有可用的选项。而应使用 transition.each()将处理程序绑定到转换。
Since transitions are a special kind of selections you cannot use all methods available to a selection on a transition. Instead, use transition.each() to bind your handler to the elements in the transition.
.transition()
.each(function () {
d3.select(this).on('mouseover', function mouseoverlogic() {});
});
