我使用jointjs / rappid。
我想在移动单元格时更改端口的属性(例如 inPort 的颜色:in0_2)。如何访问这些属性?
单元格示例:http ://www.epro.de/exchange/virtual-reality/jointjs/celltest.jpg
我想这很容易 - 我尝试了不同的方法,但找不到解决方案。
有什么提示吗?
我使用以下代码来创建单元和端口。
var graph = new joint.dia.Graph;
var paper = new joint.dia.Paper({
el: $('#paper-container'),
width: 1000,
height: 1000,
gridSize: 10,
drawGrid: true,
model: graph,
});
var l_st0 = myShapes ();
l_st0.set ('inPorts',(['in0_1', 'in0_2']));
l_st0.set ('outPorts',(['outx']));
l_st0.attr ('.label/text','MinTest');
l_st0.position (100,100);
graph.addCell(l_st0);
l_st0.on ('change:position', function() {
console.log (" change port color ");
});
function myShapes (){
joint.shapes.devs.GenericBasic = joint.shapes.devs.Model.extend({
portMarkup: '<rect class="port-body"/>',
defaults: joint.util.deepSupplement({
type: 'devs.GenericBasic',
inPorts: [],
outPorts: [],

'ref-x': .5,

}
}, joint.shapes.devs.Model.prototype.defaults)
});
joint.shapes.devs.GenericModelView = joint.shapes.devs.ModelView;
var mx = new joint.shapes.devs.GenericBasic ({
size: { width: 80, height: 100 },
attrs: {
rect: {
stroke: 'black',
'stroke-width': 1
},
}
});
return mx;
}
