我正在使用jsPlumb创建一个包含两列的匹配小部件。
jsPlumb实例创建为:
var container = $element.find('.match-widget .widget-output:not(.edit)');
jsPlumb.getInstance({
PaintStyle: {
lineWidth: 6,
strokeStyle: '#567567',
outlineColor: 'black',
outlineWidth: 1
},
MaxConnections: -1,
LogEnabled: true,
Anchors: ['Center', 'Center'],
DragOptions: {
cursor: 'pointer',
zIndex: 2000
},
Connector: ['Bezier', {
curviness: 30
}],
Endpoints: [
['Dot', {
radius: 11
}],
['Dot', {
radius: 11
}]
],
EndpointStyles: [{
fillStyle: '#FF7D19'
}, {
fillStyle: '#FF7D19'
}],
Container: container
});
我创建了源和目标,如:
jsPlumb.makeSource($(element[0]).find('.match-source-anchor')[0], {
maxConnections: 1,
uniqueEndpoint: true,
isSource: true,
enabled: true
});
jsPlumb.makeTarget($(element[0]).find('.match-target-anchor')[0], {
uniqueEndpoint: true,
isTarget: true,
maxConnections: 1,
enabled: true
});
连接过程正常。但是如果我删除连接后进行一次连接后的问题,连接终点仍然可见。
我尝试添加配置“_deleteOnDetach”,我也尝试删除connectionDetach上的端点。在这两种情况下,终点都被删除了,但在我尝试连接相同的元素时会出现错误。
那么有人可以帮我解决一下吗?

通常在删除连接时,通常会删除它的端点。在端点设置为唯一的情况下,有一个例外,在这种情况下,端点不会被删除。
请参阅jsPlumb代码:
// if unique endpoint and it's already been created, push it onto the endpoint we create. at the end
// of a successful connection we'll switch to that endpoint.
// TODO this is the same code as the programmatic endpoints create on line 1050 ish
if (def.uniqueEndpoint) {
if (!def.endpoint) {
def.endpoint = ep;
ep._deleteOnDetach = false;
ep._doNotDeleteOnDetach = true;
}
else
ep.finalEndpoint = def.endpoint;
}
