javascript - 如何在 JsPlumb 中建立与边缘的连接？

Question

如何设置 JsPlumb连接在中间 split 并到达多个端点，如下图所示？

A:用一个连接连接两个端点:

B:用一个连接连接两个端点:

C:用一个连接连接三个端点:

编辑:使用 FlowChart 选项我得到一个奇怪的错误，它是一个小点，请参见下图。

Answer 1

下面链接到带有脚本的 jsfiddle。所有蓝色 block 都是可拖动的，因此您可以试验 block 位置和连接行为。

很抱歉回答这么大 ;)

A: Connecting two endpoints with one connection:

http://jsfiddle.net/TkyJB/2/

jsPlumb.ready(function() {

    // default settings for connectors
    var connectionParams = {
        connector: ["Flowchart", {cornerRadius:1}],
        paintStyle:{ 
            lineWidth: 1,
            outlineColor:"blue",
            outlineWidth: 0
        },
        detachable:false,
        endpointStyle: { radius:1 }
    };

    // w2 <=> w1
    jsPlumb.connect({
        source: "window2", 
        target: "window1",
        anchors: ["TopCenter", "Left"]
    }, connectionParams);

    // w2 <=> w2
    jsPlumb.connect({
        source: "window2", 
        target: "window3",
        anchors: ["BottomCenter", "Left"]
    }, connectionParams);

    //
    jsPlumb.draggable(
        jsPlumb.getSelector(".window"),
        { containment:".demo"}
    );
});

B: Connecting two endpoints with one connection:

jsPlumb 规则:2 个窗口之间的一个连接。所以如果你需要在最后划分一些连接，你需要创建代理点，它将作为一个窗口的来源，并为其他窗口创建 2 个新连接。

http://jsfiddle.net/TkyJB/8/

jsPlumb.ready(function() {

    // default settings for connectors
    var connectionParams = {
        connector: ["Flowchart", {cornerRadius:1}],
        paintStyle:{ 
            lineWidth: 1,
            outlineColor:"green",
            outlineWidth: 0
        },
        detachable:false,
        endpointStyle: { radius:1 }
    };

    // w1 <=> w1s
    jsPlumb.connect({
        source: "window1", 
        target: "window1s",
        anchors: ["Right", "Center"],
        anchor:[ "Perimeter", { shape:"Circle" } ]
    }, connectionParams);

    // w1s <=> w2
    jsPlumb.connect({
        source: "window1s", 
        target: "window2",
        anchors: ["Center", "Bottom"]
    }, connectionParams);

    // w1s <=> w3
    jsPlumb.connect({
        source: "window1s", 
        target: "window3",
        anchors: ["Center", "Top"]
    }, connectionParams);

    //
    jsPlumb.draggable(
        jsPlumb.getSelector(".window"),
        { containment:".demo"}
    );
});

C: Connecting three endpoints with one connection:

它将与“B”中的相同，但有额外的隐藏代理 block 。

http://jsfiddle.net/TkyJB/7/

jsPlumb.ready(function() {

    // default settings for connectors
    var connectionParams = {
        connector: ["Flowchart", {cornerRadius:1}],
        paintStyle:{ 
            lineWidth: 1,
            outlineColor:"blue",
            outlineWidth: 0
        },
        detachable:false,
        endpointStyle: { radius:1 }
    };

    // w1 <=> w1s1
    jsPlumb.connect({
        source: "window1", 
        target: "window1s1",
        anchors: ["Right", "Center"]
    }, connectionParams);

    // w1s1 <=> w1s2
    jsPlumb.connect({
        source: "window1s1", 
        target: "window1s2",
        anchors: ["Center", "Center"]
    }, connectionParams);

    // w1s1 <=> w2
    jsPlumb.connect({
        source: "window1s1", 
        target: "window2",
        anchors: ["TopCenter", "Left"]
    }, connectionParams);

    // w1s1 <=> w3
    jsPlumb.connect({
        source: "window1s1", 
        target: "window3",
        anchors: ["BottomCenter", "Left"]
    }, connectionParams);

    // w1s2 <=> w4
    jsPlumb.connect({
        source: "window1s2", 
        target: "window4",
        anchors: ["Right", "Left"]
    }, connectionParams);

    //
    jsPlumb.draggable(
        jsPlumb.getSelector(".window"),
        { containment:".demo"}
    );

});
