介绍
使用svg完成画图,四个概念:
anchor: endpoint在的位置,可通过name访问
endpoint:connection的一端节点,通过addPoint makeSource, connect创建,
connector:连接线
overlay:connector的装饰组件,如labelarrow
一个connection由一个connector,两个endpoint,0或者多个overlay构成,每个endpoint有一个关联的anchor.
anchor有四种类型:
connectors四种类型
endpoint有四种类型
overlay有五种类型
location:
connections:
adding:在connectmakeSource addEndpoint中
show和hideoverlay:connection.hideOverlay,connection.showOverlay ,endPoint有同样的方法
removeoverlay:connection.removeOverlay()
重用commonsetting
var common = {
anchors:[ "BottomCenter", "TopCenter" ],
endpoints:["Dot", "Blank" ]
};
jsPlumb.connect({ source:"someElement", target:"someOtherElement" }, common);
jsPlumb.connect({ source:"aThirdElement", target:"yetAnotherElement" }, common);
画连线
设置endPoint为 source
var exampleGreyEndpointOptions = {
endpoint:"Rectangle",
paintStyle:{ width:25, height:21, fillStyle:'#666' },
isSource:true,
connectorStyle : { strokeStyle:"#666" },
isTarget:true
};
var endpoint = jsPlumb.addEndpoint('elementId', exampleGreyEndpointOptions
);
makeTarget和makeSource
将整个element变成target或source
jsPlumb.makeSource("el1", {
anchor:"Continuous",
endpoint:["Rectangle", { width:40, height:20 }],
maxConnections:3
});
uniqueEndpoint:
设置只有一个 endPoint
移除connections和endpoint
jsPlumb.detach(conn);
删除
el
上所有链接:
jsPlumb.detachAllConnections(el, [params])
所有链接:jsPlumb.detachEveryConnection();
通过connect中的parameters参数向jsPlumb中传入参数。
动画:
jsPlumb.animate : function(el, properties, options)
调用方式类似于
jQuery
查询jsPlumb
css样式
overlays: cssClass
paintStyle可设置:fillStyle strokeStyle lineWidth outlineWidth outlineColordashStyle
hoverpaint style
hoverPaintStyle endpointHoverStyles
