question that is very similar but answer doesn't work in my situation
我有一个圆圈,我想将click事件传递给它下面的任何对象。
我试过了:
将cancelbubble设置为false。 将cirle图层设置为listen = false对我不起作用,因为圆圈不再可拖动。
我做了一个小提琴here
var stage = new Kinetic.Stage({
container: 'container',
width: 578,
height: 400
});
var layer = new Kinetic.Layer();
var background = new Kinetic.Layer();
var colorPentagon = new Kinetic.RegularPolygon({
x: 80,
y: stage.getHeight() / 2,
sides: 5,
radius: 70,
fill: 'red',
stroke: 'black',
strokeWidth: 4,
draggable: true
});
colorPentagon.on('click', function(evt){ alert("pentagon");});
var linearGradPentagon = new Kinetic.RegularPolygon({
x: 360,
y: stage.height()/2,
sides: 5,
radius: 70,
fillLinearGradientStartPoint: {x:-50, y:-50},
fillLinearGradientEndPoint: {x:50,y:50},
fillLinearGradientColorStops: [0, 'red', 1, 'yellow'],
stroke: 'black',
strokeWidth: 4,
draggable: true
});
linearGradPentagon.on('click', function(evt){ alert("pentagon");});
var radialGradPentagon = new Kinetic.RegularPolygon({
x: 500,
y: stage.height()/2,
sides: 5,
radius: 70,
fillRadialGradientEndRadius: 70,
fillRadialGradientColorStops: [0, 'red', 0.5, 'yellow', 1, 'blue'],
stroke: 'black',
strokeWidth: 4,
draggable: true
});
radialGradPentagon.on('click', function(evt){ alert("pentagon");});
background.add(colorPentagon);
//background.add(patternPentagon);
background.add(linearGradPentagon);
background.add(radialGradPentagon);
stage.add(background);
var hideCircle = new Kinetic.Circle({
x: stage.width()/2,
y: stage.height()/2,
radius: 650,
stroke: 'black',
strokeWidth: 1000,
draggable:true
});
hideCircle.on('click', function(evt){ alert("click");});
// add the shape to the layer
layer.add(hideCircle);
// add the layer to the stage
stage.add(layer);
目前为了让它工作,我必须采取点击坐标并进行自己的检测。它有效,但我希望有更优雅的东西。

以下是将点击事件传递给底层节点的方法:
您可以听取舞台上的点击次数
确定点击是否位于底层的任何节点
如果单击位于节点内,则触发该节点上的click事件。
以下是示例代码和演示:http://jsfiddle.net/m1erickson/sFX8y/
stage.on('contentClick',function(e){
// get the mouse position
var pos=stage.getPointerPosition();
// fetch the node on the bottom layer that is under the mouse, if any.
var hitThisNode=background.getIntersection(pos);
// if a node was hit, fire the click event on that node
if(hitThisNode){
hitThisNode.fire("click",e,true);
}
});
