问题
I have a joint.js element in a DAG, and would like to be able to trigger an event by clicking on it.
I could use $(selector).click(...)
to do it, but I was wondering if there was a joint.js specific way of handling it,
since that would probobly be better. One event I decided was a candidate for onclick was 'batch:stop'
My code:
var variable = new joint.shapes.basic.Rect({
name : label,
id: label,
onclick : function () {alert("hello");},
size: { width: width, height: height },
attrs: {
text: { text: label, 'font-size': letterSize, 'font-family': 'monospace' },
rect: {
fill : fillColor,
width: width, height: height,
rx: 5, ry: 5,
stroke: '#555'
}
}
});
variable.on('batch:stop', function (element) {alert(""); toggleEvidence(element.name);});
return variable;
How should I add an onclick event?
回答1:
The JointJS shapes are models, so you're right that click handlers won't work on them. The JointJS paper triggers events that might be useful to you:
paper.on('cell:pointerdown',
function(cellView, evt, x, y) {
alert('cell view ' + cellView.model.id + ' was clicked');
}
);
other events are: cell:pointerup, cell:pointerdblclick, cell:pointermove.
The complete list can be found here: http://jointjs.com/api#joint.dia.Paper:events.
EDIT:
Starting from JointJS v0.9, there is also a cell:pointerclick
event.

You can also use Backbone itself to attach specific events to specific models. JointJS is just Backbone under the hood.
const newElement = new jointjs.shapes.devs.Model({....});
graph.addCell(newElement);
newElement
.findView(paper)
.$el.find('.Settings') // this is nested in the model / cell
.click(() => {
// do something
});
