如何在jsplumb中从源端点建立多个连接
问题描述:
我想用jsplumb库制作一个流程图。我需要从一个div创建多个连接。 Ex-Div 1应该连接到Div 2和Div 3.我希望源端点是相同的,即bottomcenter。请让我知道该做什么工作 谢谢!如何在jsplumb中从源端点建立多个连接

使用下面的代码DIV1连接到DIV2和DIV3
<html>
<script src="http://code.jquery.com/jquery-1.9.1.js"></script>
<script src="http://code.jquery.com/ui/1.10.4/jquery-ui.js"></script>
<script src="/js/JsPlumb/jquery.jsPlumb-1.4.1-all-min.js"></script>
<script type="text/javascript">
$(document).ready(function(){
$(".inner").draggable({
containment : ([ ".outer" ]),
});
var source = $("#div1");
var target = $("#div2");
var target2 = $("#div3");
jsPlumb.connect({
source : source,
target : target
});
jsPlumb.connect({
source : source,
target : target2
});
});
</script>
<style type="text/css">
#outer{
height: 300px;
width: 300px;
/*background-color: red;*/
}
.inner{
height: 30px;
width: 30px;
background-color: yellow;
margin-bottom: 37px;
}
#div2{
position: relative; left: 114px; top: -7px;
}
</style>
<body>
<div id="outer">
<div class="inner" id="div1">
</div>
<div class="inner" id="div2">
</div>
<div class="inner" id="div3">
</div>
</div>
</body>
</html>
添加jsPlumb库

对于目标终点设置全局做出无限连接:
var targetEndpoint = {
endpoint: "Dot",
paintStyle: { fillStyle: "blue", radius: 7 },
hoverPaintStyle: endpointHoverStyle,
maxConnections: -1,
dropOptions: { hoverClass: "hover", activeClass: "active" },
isTarget: true,
overlays: [["Label", { location: [0.5, -0.5], label: "", cssClass: "endpointTargetLabel" }]]
};
源端点将其设置为全局以实现无限连接:
var sourceEndpoint = {
endpoint: "Dot",
paintStyle: {
strokeStyle: "green", fillStyle: "green", radius: 3, lineWidth: 1
},
isSource: true,
maxConnections: -1,
connector: ["Flowchart", { stub: [40, 60], gap: 10, cornerRadius: 5, alwaysRespectStubs: true }],
connectorStyle: connectorPaintStyle, hoverPaintStyle: endpointHoverStyle, connectorHoverStyle: connectorHoverStyle,
dragOptions: {},
overlays: [["Label", { location: [0.5, 1.5], label: "", cssClass: "endpointSourceLabel", }]]
};
我得到了这个答案。在创建端点时,您可以将maxConnections:-1, 设置为无限连接。如果你设置了一些值,那么它只能使连接数等于值。您需要在sourceEndpoint和targetEndpoint创建时间中指定此项 – 2012-08-23 18:54:46
由于某种原因,此解决方案对我无效。 – spadelives 2012-12-11 06:28:59
@ user1667230:您是否试图将maxConnections = -1添加到两个端点?如果没有,那么尝试一下。 – 2012-12-11 18:06:14
