cshtmlpage には、次の要素があります。

<g transform="translate(@x @y)" width="@(r * 2)" height="@(r * 2)" onclick="Topology.GroupDiagramPage.click()">
<circle r="@r" class="diagram-node" />

    @if(node.NodeStatus != NodeStatus.None)
    {
        bool isPaly = node.NodeStatus == NodeStatus.Running;
        string playVisibslityClass = isPaly ? "" : "not-visibility";
        string stopVisibslityClass = !isPaly ? "" : "not-visibility"; 

<rect id="@("topology-diagram-" + node.Id + "-status-stop")" width="16" height="16" fill="#CA3D3C" x="-8" y="-8" class="@stopVisibslityClass"/>
<polygon id="@("topology-diagram-" + node.Id + "-status-play")"  points="-5, -10 10, 0 -5, 10" fill="#009A22" class="@playVisibslityClass"/>
    }
</g>

そして、バックボーンスクリプトのこの要素

    click: function () {
        colsole.log("Clic!");
    }
});

スクリプトで発信者の「click ()」をクリックする必要があります。
"" 要素を攻撃すると、このイベント: onclick="Topology.GroupDiagramPage.click()" が発生します: Uncaught ReferenceError: Topology is not defined

これはどうすればよい&

あなたのコードと質問から私が理解しているのは、何らかのアクションでビューのメソッドを実行したい場合は、バックボーン ビューのイベント ハッシュを使用する必要があるということです。

ラインを考えると、

this.$el.svg({ id: this.groupid, class: "topology-diagram", style: "width: " + allWidth + "; height: " + allHeight });

メソッドのは、属性がである DOMdiagram()に a を追加し、それをクリックして実行したい場合は、dividdiv_idview

// this event binding will execute click method whenever you click on a div 
// whose id is 'div_id'
events : {
  "click #div_id" : "click" 
}

これはあなたの質問の解決策ではありませんが、達成したいことを達成する方法です。
