JSPlumb 端点多连接

JSPlumb Endpoint Multiple Connections

我有一些 div 元素,我想通过 JSPlumb Community Edition 连接它们。我在 javascript:

中有这行代码
$("#create_item").click(function() {
    var $i = "item" + counter;
    var $txt = "Create " + counter;
    var $div = $("<div>", {id: $i, class: "box create", text: $txt});
    $(".container").append($div);
    counter++;
    jsPlumb.ready(function() {
        jsPlumb.draggable($i, {containment:"parent"});
        jsPlumb.addEndpoint($i, { 
            anchor:"Right" },
            sourceEndpointOptions);
    });
});

$("#dispose_item").click(function() {
    var $i = "item" + counter;
    var $txt = "Dispose " + counter;
    var $div = $("<div>", {id: $i, class: "box dispose", text: $txt});
    $(".container").append($div);
    counter++;
    jsPlumb.ready(function() {
        jsPlumb.draggable($i, {containment:"parent"});
        jsPlumb.addEndpoint($i, { 
            anchor:"Left" },
            targetEndpointOptions);
    });
});

var sourceEndpointOptions = {
    endpoint:"Dot",
    paintStyle:{ width:15, height:15, fillStyle:'#666' },
    isSource:true,
    connectorStyle : { strokeStyle:"#666" },
    isTarget:false
};

var targetEndpointOptions = {
    endpoint:"Dot",
    paintStyle:{ width:15, height:15, fillStyle:'#460CE8' },
    isSource:false,
    connectorStyle : { strokeStyle:"#460CE8" },
    isTarget:true
};

我想做的是在运行时制作两个 #create_tem 和一个 #dispose_item 并将两个源端点连接到目标端点,但是当我将一个源连接到目标时,目标不会接受第二个来源。我该怎么做?

我在终点选项中缺少 maxConnections:-1
