端口的位置在 中计算devs.Model.prototype.getPortAttrs
。您可以做的只是交换x
和y
端口坐标,如下例所示。
joint.shapes.devs.Model = joint.shapes.basic.Generic.extend(_.extend({}, joint.shapes.basic.PortsModelInterface, {
markup: '<g class="rotatable"><g class="scalable"><rect class="body"/></g><text class="label"/><g class="inPorts"/><g class="outPorts"/></g>',
portMarkup: '<g class="port port<%= id %>"><circle class="port-body"/><text class="port-label"/></g>',
defaults: joint.util.deepSupplement({
type: 'devs.Model',
size: { width: 1, height: 1 },
inPorts: [],
outPorts: [],
attrs: {
'.': { magnet: false },
'.body': {
width: 150, height: 250,
stroke: 'black'
},
'.port-body': {
r: 10,
magnet: true,
stroke: 'black'
},
text: {
fill: 'black',
'pointer-events': 'none'
},
'.label': { text: 'Model', 'ref-x': 10, 'ref-y': .2, 'ref': '.body' },
// CHANGED: find better positions for port labels
'.inPorts .port-label': { dy:-30, x: 4 },
'.outPorts .port-label':{ dy: 15, x: 4 }
//
}
}, joint.shapes.basic.Generic.prototype.defaults),
getPortAttrs: function(portName, index, total, selector, type) {
var attrs = {};
var portClass = 'port' + index;
var portSelector = selector + '>.' + portClass;
var portLabelSelector = portSelector + '>.port-label';
var portBodySelector = portSelector + '>.port-body';
attrs[portLabelSelector] = { text: portName };
attrs[portBodySelector] = { port: { id: portName || _.uniqueId(type) , type: type } };
// CHANGED: swap x and y ports coordinates ('ref-y' => 'ref-x')
attrs[portSelector] = { ref: '.body', 'ref-x': (index + 0.5) * (1 / total) };
// ('ref-dx' => 'ref-dy')
if (selector === '.outPorts') { attrs[portSelector]['ref-dy'] = 0; }
//
return attrs;
}
}));

更新:
这是一个如何使用 JointJS 实现相同的示例v1.0.1+
。
不再需要扩展类PortsModelInterface
。端口 API 现在由joint.dia.Element
ie 实现,可以轻松地用端口丰富任意元素。
var shape = new joint.shapes.devs.Model({
inPorts: ['in1', 'in2'],
outPorts: ['out1', 'out2'],
ports: {
groups: {
'in': { position: 'top'},
'out': { position: 'bottom' }
}
}
});
