问题
I'm trying to add an onClick event to an existing svg. Right now I have this :
<g id="Group" onClick={this.clickGroup.bind(this, 1)}>
Which somewhat works but not entirely... The event fires when I click the group but the "zone" that is clickable isn't the same as the group I want to be clickable (it seems completely random to me).
Is there any better way to add events to a <g>element (with React ?) ?
回答1:
A g element is just an empty container; it can not fire events by itself.
If you run this example, you'll see that you can trigger the click event by clicking on the children of the g element, but you can't if you click in the empty space between them.
You have to use actual shapes to fire events in SVG.
回答2:
Use style pointer-events as bounding-box to make the group clickable any where on the group.Even at the empty places
<g id="Group" onClick={this.clickGroup.bind(this, 1)} style="pointer-events: bounding-box;">
