我正在尋找在生成圖形後基於某些外部數據更改JointJS圖形中的端口顏色。動態更改JointJS端口顏色
我試過下面的代碼:
var l_portsIn = this.model.get('inPorts');
if (l_portsIn.length > 0){
this.portProp ('in1','attrs/rect',{stroke: 'red' });
}
其中「IN1」是我的端口的ID,我需要改變。
這是我的關節對象:

不幸的是,我發現了以下錯誤:

挖入關節的js庫的代碼,它看起來像這樣的功能是罪魁禍首(在joint.js文件中):
getPortIndex: function(port) {
var id = _.isObject(port) ? port.id : port;
if (!this._isValidPortId(id)) {
return -1;
}
return _.findIndex(this.prop('ports/items'), { id: id });
}
當我console.log this.prop('ports/items')
,它是unde罰款。
有沒有人有任何想法?
如果我做的: --- VAR firstElement = graph.getElements() 0]; console.log(firstElement.getPort('in1')); --- 這是在瀏覽器控制檯中返回'undefined'。 –
您需要參考您的圖表...我將以示例發佈anowser – Astronaut
