引言:首先写这篇文章是为了记录一下自己用到的api,以及接触到的设置方法,部分详解有摘自其他博主的文章,我主要是在vue中使用,涉及到业务方面的就不过多解释,react我也自测过,都是同一个套路,希望本篇文章能帮助到各位码友!!!
npm install gojs --save
我目前装的应该现在最新版的 “gojs”: “^2.2.14”,
我在博客也搜到不少解决的方法,在这里就分享两种方法:
第一种: 在node_modules中找到go.js,go.mjs,go-module.js路径如下:node_modules/gojs/release/go.js,go.mjs,go-module.js (注意:最好是这三个文件都要改,有些码友说设置了没用,原因是只设置了go.js)
这一种也是我目前使用的方法: 在三个文件全局搜索 7ca11abfd022028846 然后将这一行的剩余部分全部删除,下面是我已经删除后的照片:记得三个文件都要删除
搜索String.fromCharCode(a.charCodeAt(g)^b[(b[c]+b[d])%256]) 这段代码后面会有个return f;
在return f 前加上以下代码
// 注意了: 如果你是2022版本的话需要,将© 1998-2021 Northwoods Software 改成 © 1998-2022 Northwoods Software
// 这个你可以在水印上查看是哪个年限以及哪个版本:
if(f.indexOf(‘GoJS 2.1 evaluation’)>-1
|| f.indexOf(‘© 1998-2021 Northwoods Software’)>-1
|| f.indexOf(‘Not for distribution or production use’)>-1
|| f.indexOf(‘gojs.net’)>-1
){
return ‘’;
}else{
return f
}

样式什么的可以自己设置
为了您的方便,我们定义了几个常用的面板。 这些按钮包括"Button"、“TreeExpanderButton”、“SubGraphExpanderButton”、“PanelExpanderButton”、“ContextMenuButton"和"CheckBoxButton”。 "ContextMenuButton"通常在"ContextMenu"面板内使用; “复选框按钮”用于实现“复选框”面板。
在调用GraphObject.make时,可以像使用面板派生类一样使用这些预定义的面板。 它们被实现为面板中GraphObjects的简单可视化树,具有预先设置的属性和事件处理程序。

这个也是我自己需要引入的按钮,上文已经介绍
扩展和折叠子树是很常见的。 通过在节点模板中添加“TreeExpanderButton”的实例,很容易让用户控制这一点。 该按钮调用CommandHandler。 collapseTree或CommandHandler。 expandTree取决于Node.isTreeExpanded的值。 按钮图标的形状。 图随节点值的变化而变化。 isTreeExpanded变化。
diagram.nodeTemplate =
$(go.Node, "Spot",
$(go.Panel, "Auto",
$(go.Shape, "Rectangle",
{ fill: "gold" }),
$(go.TextBlock, "Click small button\nto collapse/expand subtree",
{ margin: 5 })
),
$("TreeExpanderButton",
{ alignment: go.Spot.Bottom, alignmentFocus: go.Spot.Top },
{ visible: true })
);
diagram.layout = $(go.TreeLayout, { angle: 90 });
diagram.model = new go.GraphLinksModel(
[ { key: 1 },
{ key: 2 } ],
[ { from: 1, to: 2 } ] );
diagram.nodeTemplate =
$(go.Node, "Spot",
$(go.Panel, "Auto",
$(go.Shape, "Rectangle",
{ fill: "gold" }),
$(go.TextBlock, "Click small button\nto collapse/expand subtree",
{ margin: 5 })
),
$("TreeExpanderButton",
{
// set the two additional properties used by "TreeExpanderButton"
// that control the shape depending on the value of Node.isTreeExpanded
"_treeExpandedFigure": "TriangleUp",
"_treeCollapsedFigure": "TriangleDown",
// set properties on the icon within the border
"ButtonIcon.fill": "darkcyan",
"ButtonIcon.strokeWidth": 0,
// set general "Button" properties
"ButtonBorder.figure": "Circle",
"ButtonBorder.stroke": "darkcyan",
"_buttonStrokeOver": "darkcyan"
},
{ alignment: go.Spot.Bottom, alignmentFocus: go.Spot.Top },
{ visible: true })
);
diagram.layout = $(go.TreeLayout, { angle: 90 });
diagram.model = new go.GraphLinksModel(
[ { key: 1 },
{ key: 2 } ],
[ { from: 1, to: 2 } ] );
还经常需要展开和折叠包含子图的组。 您可以通过向组模板添加“SubGraphExpanderButton”的实例来让用户控制这一点。 该按钮调用CommandHandler。 collapseSubGraph或CommandHandler。 expandSubGraph取决于Group.isSubGraphExpanded的值。 按钮图标的形状。 图随Group值的变化而变化。 isSubGraphExpanded变化。
diagram.groupTemplate =
$(go.Group, "Auto",
$(go.Shape, "Rectangle",
{ fill: "gold" }),
$(go.Panel, "Vertical",
{ margin: 5,
defaultAlignment: go.Spot.Left },
$(go.Panel, "Horizontal",
$("SubGraphExpanderButton",
{ margin: new go.Margin(0, 3, 5, 0) }),
$(go.TextBlock, "Group")
),
$(go.Placeholder)
)
);
diagram.model = new go.GraphLinksModel(
[ { key: 0, isGroup: true },
{ key: 1, group: 0 },
{ key: 2, group: 0 },
{ key: 3, group: 0 } ] );
“SubGraphExpanderButton”类似于“TreeExpanderButton”,因为它是一个“按钮”,其边框形状围绕图标形状。 该形状被命名为“ButtonIcon”,因此您可以轻松地设置或绑定它的属性,以及“ButtonBorder”和“Button”本身的属性。

通常希望展开和折叠节点的一部分,从而显示或隐藏有时不需要的细节。 通过在节点模板中添加“PanelExpanderButton”的实例,很容易让用户控制这一点。 GraphObject的第二个参数。 make应该是一个字符串,用于命名节点中GraphObject. make的元素。 您希望按钮切换的可视属性。

“PanelExpanderButton”类似于“TreeExpanderButton”或“SubGraphExpanderButton”,因为它是一个“按钮”,其边框形状围绕图标形状。 然而,此面板绑定形状。 几何字符串而不是Shape.figure。
diagram.nodeTemplate =
$(go.Node, "Auto",
$(go.Shape,
{ fill: "gold" }),
$(go.Panel, "Table",
{ defaultAlignment: go.Spot.Top, defaultColumnSeparatorStroke: "black" },
$(go.Panel, "Table",

$(go.TextBlock, "List 1",

// 设置"PanelExpanderButton"使用的两个附加属性

"_buttonExpandedFigure": "M0 0 L10 0",

尽管您可以以任何您选择的方式实现上下文菜单,但通常使用预定义的“ContextMenuButton”。
diagram.nodeTemplate =
$(go.Node, "Auto",
$(go.Shape, "Rectangle",
{ fill: "gold" }),
$(go.TextBlock, "Use ContextMenu!",
{ margin: 5 })
);
diagram.nodeTemplate.contextMenu =
$("ContextMenu",
$("ContextMenuButton",
$(go.TextBlock, "Shift Left"),
{ click: function(e, obj) { shiftNode(obj, -20); } }),
$("ContextMenuButton",
$(go.TextBlock, "Shift Right"),
{ click: function(e, obj) { shiftNode(obj, +20); } })
);
function shiftNode(obj, dist) {
var adorn = obj.part;
var node = adorn.adornedPart;
node.diagram.commit(function(d) {
var pos = node.location.copy();
pos.x += dist;
node.location = pos;
}, "Shift");
}
diagram.model = new go.GraphLinksModel(
[ { key: 1 } ] );
“ContextMenuButton”只是一个设置了一些属性的“按钮”。 其中一个属性是GraphObject。 它被设置为go.GraphObject.Horizontal,这样“ContextMenu”中的所有“ContextMenuButton”都将被拉伸到相同的宽度。 但是你可以在它的“ButtonBorder”形状和按钮本身上设置所有常用的属性。
diagram.nodeTemplate =
$(go.Node, "Auto",
$(go.Shape, "Rectangle",
{ fill: "gold" }),
$(go.TextBlock, "Use ContextMenu!",
{ margin: 5 })
);
diagram.nodeTemplate.contextMenu =
$("ContextMenu",
$("ContextMenuButton",
{
"ButtonBorder.fill": "yellow",
"_buttonFillOver": "cyan",
"_buttonFillPressed": "lime"
},
$(go.TextBlock, "Shift Left"),
{ click: function(e, obj) { shiftNode(obj, -20); } }
),
$("ContextMenuButton",
{
"ButtonBorder.fill": "yellow",
"_buttonFillOver": "cyan",
"_buttonFillPressed": "lime"
},
$(go.TextBlock, "Shift Right"),
{ click: function(e, obj) { shiftNode(obj, +20); } }
),
$("ContextMenuButton",
{ isEnabled: false },
$(go.TextBlock, "Shift Right", { stroke: "gray" }),
{ click: function(e, obj) { alert("won't be alerted"); } }
)
);
function shiftNode(obj, dist) {
var adorn = obj.part;
var node = adorn.adornedPart;
node.diagram.commit(function(d) {
var pos = node.location.copy();
pos.x += dist;
node.location = pos;
}, "Shift");
}
diagram.model = new go.GraphLinksModel(
[ { key: 1 } ] );
