前端流程图jsplumb学习笔记

1、这篇博客很好,另外两个是官网文档

https://jsplumbtoolkit.com/community/apidocs/classes/Connector.html

https://jsplumbtoolkit.com/community/doc/connections.html#draganddrop

2、Jsplump流程图画虚线用"dashstyle": "2 4"

PaintStyle: {

                            lineWidth: 3,

                            strokeStyle: color,

                            "dashstyle": "2 4"

                         }

3、简单连接

 jsPlumb.connect({
  source:"window4",
  target:"window5",
  anchors:["BottomRight","TopLeft"],
  paintStyle:{strokeWidth:7,stroke:'rgb(131,8,135)'},
  hoverPaintStyle:{ stroke:"rgb(0, 0, 135)" },
  endpointStyle:{ 40, height:40 },
  endpoint:"Rectangle",
  connector:["Flowchart", { midpoint: 0.8}],
   overlays:[
    [ "Label", {label:"FOO", id:"label", location:0.7
}]
  ] 
});

(1)connector:["Flowchart", { midpoint: 0.8}],设置折线抓点的位置,

0-1,越小离源端点越近

 (2)label location 0-1, 越小离源端点越近

(3)配置项写法都是name:[“type1”,{option1:value,option2:value2}]

(4)anchors:[[ 0,0.5, -1, 0 ],"RightMiddle"], 用数组自定义anchor位置,

[x,y,dx,dy],x和y为以noder的左上角为起点,向下或向右增加到1。dx、dy指连接线出去的x、y方向矢量的分量,dx/dy组合定义出成一个角度,取值-1到1。-1为向左,向上,1为向右和向下。0分别为垂直和水平方向。

4、 Connection.连接器, Connector连接线是连接器的一个组成要素

5、用css设置connection连接器样式

jsPlumb.connect({

  source:"someElement",

  target:"someOtherElement",

 cssClass: "redLine dashLine",

});

CSS:

svg.redLine path {

              stroke: red;

              stroke- 3;

           }

          

           svg.dashLine path {

              stroke-dasharray: 5;

           }

注svg虚线样式规则参照

6、动态切换connection paintstyle

instance.registerConnectionType("black", {

       paintStyle: {

           strokeWidth: 2,

           stroke: "#000000",

           joinstyle: "round",

           outlineStroke: "white",

           outlineWidth: 2,

           "dashstyle": "2 4"

       },

    });

var aa = instance.connect({

           uuids: ["Window1BottomCenter", "Window2TopCenter"],

           editable: true,

           type: "black"

       });

或aa.setType(“black”)

7、批量加入connection

   jsPlumb.ready(function () {

                var color = "#0070c0";

                var instance = jsPlumb.getInstance({

                    Connector: ["Straight", { curviness: 2 }],

                    PaintStyle: {

                        strokeWidth: 2,

                        stroke: "#0070c0",

                        joinstyle: "round",

                        outlineWidth: 2

                    },

                    EndpointStyle: { radius: 1, fillStyle: color },

                    Container: "canvas"

                });

                var _addEndpoints = function (nodeId, sourceAnchors, targetAnchors) {

                    for (var i = 0; i < sourceAnchors.length; i++) {

                        var sourceUUID = nodeId + "-" + sourceAnchors[i];

                        instance.addEndpoint(nodeId, {

                            anchor: sourceAnchors[i], uuid: sourceUUID

                        });

                    }

                    for (var j = 0; j < targetAnchors.length; j++) {

                        var targetUUID = nodeId + "-" + targetAnchors[j];

                        instance.addEndpoint(nodeId, { anchor: targetAnchors[j], uuid: targetUUID });

                    }

                };

                instance.batch(function () {

                    var arrowCommon = { foldback: 0.7, fillStyle: color, 14 },

                        overlays = [

                            ["Arrow", { location: 1 }, arrowCommon,],

                        ];

                    _addEndpoints("nodeSiteInspectionRecordMainCheck", ["RightMiddle"], []);

                    _addEndpoints("nodeCorrectionInstructionBook", ["RightMiddle"], ["LeftMiddle"]);

                    _addEndpoints("nodeSiteInspectionRecordRecheck", ["RightMiddle"], ["LeftMiddle"]);

                    _addEndpoints("nodeCorrectiveReviewOpinions", ["RightMiddle"], ["LeftMiddle"]);

                    _addEndpoints("nodeArchive", [], ["LeftMiddle"]);

                    instance.connect({ uuids: ["nodeSiteInspectionRecordMainCheck-RightMiddle", "nodeCorrectionInstructionBook-LeftMiddle"], overlays: overlays });

                    instance.connect({ uuids: ["nodeCorrectionInstructionBook-RightMiddle", "nodeSiteInspectionRecordRecheck-LeftMiddle"], overlays: overlays });

                    instance.connect({ uuids: ["nodeSiteInspectionRecordRecheck-RightMiddle", "nodeCorrectiveReviewOpinions-LeftMiddle"], overlays: overlays });

                    instance.connect({ uuids: ["nodeCorrectiveReviewOpinions-RightMiddle", "nodeArchive-LeftMiddle"], overlays: overlays });

                });

                jsPlumb.fire("jsPlumbDemoLoaded", instance);

            });

8、配置事件以及label位置内容配置

label压线问题:(1)用jquery修改top。避免label压住水平方向的连线

var flowchartWindow1_flowchartWindow2_connection = jsPlumb.connect({

           });

    flowchartWindow1_flowchartWindow2_connection.setLabel({

       label: "上级立案上级立案上级立案",

       location: 0.2,

       cssClass: "connection-label"

    });

    var label = flowchartWindow1_flowchartWindow2_connection.getLabelOverlay().canvas;

    var originTop = $(label).position().top;

$(label).css("top", originTop - 30 + "px");

(2)而且将label的marginleft设置成width的一半多点,避免label压住垂直方向的连线

.remarksLabel {

    color: #ff0000;

    font-size: 8px;

    80px;

    height: 40px;

    margin-left: 45px;

}

1、 菱形节点,用css实现,背景图片

2、 节点旁边的标注,在nodetext边添加label标识

3、 后台连接器(connection)数据模型整理

(1)sourceNodeId string 源节点id,要与页面的id一致; 

(2)targetNodeId string 目标节点id,要与页面的id一致;

(3)ConnectionCssClass string要与页面的css名类一致;;

(4)anchors:两种类型:[[ 0,0.3, -1, 0 ],"RightMiddle"]和[“LeftMiddle”,"RightMiddle"]

统一做成数值型的[[ 0,0.3, -1, 0 ], [ 0,0.3, -1, 0 ]]

(5)ConnectorMidpoint: double折点比例位置

(6)LabelText:string 连旁标签内容

(7)LabelLocation:double 标签在连线上的位置

         jsPlumb.connect({

                  source: "flowchartWindow1",

                  target: "flowchartWindow2",

                  cssClass: "redline dashline",

                  anchors:[[ 0,0.3, -1, 0 ],"RightMiddle"],

                  connector:["Flowchart", { midpoint: 0.9}],

                  overlays: [

                          ["Label", {

                                   label: "上级立案上级立案上级立案",

                                   id: "label",

                                   location:0.6

                          }]

                  ]

         });

4、 后台节点数据模型

{

                    "NodeId": "nodeSiteInspectionRecordMainCheck",

                    "SystemName": "SiteInspectionRecord",

                    "WriteStateCssClassName": "finished",

                    "MissionId": "574A979F-4471-4441-A6B3-493B3F6479FA",

                    "IsWritedByApp": "false",

                    "HasAttachmentFiles": "true"

                },

7、connection.setLabel({

               label: "上级立案上级立案上级立案",

              location:0.8,

              cssClass:"connection-label"

       });

8、 jsPlumb.select().addClass("dashLine");

获取连接器增加css类

9、anthor常用值

RightMiddle { 1, 0.5, 1, 0 }

LeftMiddle{ 0, 0.5, -1, 0 } ,

BottomCenter{ 0.5, 1, 0, 1 },

 TopCenter{ 0.5, 0, 0, -1 }

右左{{ 1, 0.5, 1, 0 },{ 0, 0.5, -1, 0 } }

下上{{ 0.5, 1, 0, 1 },{ 0.5, 0, 0, -1 } }
