如何在var NoProto = NoProto || {};
NoProto.Shape = (function(){
var thing = function(name){
var privateData = 'this is a ' + name;
var self = this;
this.base = function(){
return self;
};
this.doStuff = function(){
return privateData;
};
};
return thing;
})();
NoProto.Square = (function(){
var thing = function(colour){
NoProto.Shape.call(this, "square");
const oldDoStuff = this.doStuff;
this.doStuff = function(){
var val = oldDoStuff();
return val + ', which is '+ colour;
};
};
thing.prototype = Object.create(NoProto.Shape.prototype);
return thing;
})();
var noProtoSqr = new NoProto.Square('blue');
try {
console.log(noProtoSqr.doStuff()); // ---> Stack Overflow!
} catch (e){
console.error('There was an error: ' + e);
}中使边缘不重叠？
还是边缘重叠最少？
我使用布局Cytoscape js。
