问题描述
1）我正在使用JointJS图表库。我想在使用 joint.shapes.devs 时更改特定 inPort 的css。
1) I'm using JointJS diagramming lib. I want to change the css of a particular inPort when using joint.shapes.devs.
使用
source：{id：source.id，selector ：source.getPortSelector（sourcePort）}
它给我准确的源端口，但是如何应用css在这个特定端口知道它我的源连接器？有办法吗？
It's giving me accurate source port, but how to apply css on this particular port after knowing it as my source connector? Is there a way?
2）如果标签的宽度大于元素宽度，我们是否可以在元素中自动套用标签？我使用 joint.shapes.devs.Atomic 元素。
2) Can we fit/wrap the label automatically inside the element if its width is longer than the element-width? I'm using joint.shapes.devs.Atomic element(s).
$ c> foreignobject 但不知道如何使用它呢？
任何人都可以点亮它吗？
I came across foreignobject but don't know how to use it? Can anyone throw some light on it?
推荐答案
1）
myShape.attr('[port="a"]/fill', 'blue')
其中斜杠之前的第一个参数的第一部分是指向端口圆SVG元素的CSS选择器，第二个部分是要在该元素上设置的SVG属性，第二个argument是要为该属性设置的值。执行相同操作的另一种语法是：
where the first part of the first argument before slash is a CSS selector pointing to the port circle SVG element, the second part is an SVG attribute to be set on that element and the second argument is a value to be set for that attribute. An alternative syntax for doing the same thing would be:
myShape.attr({ '[port="a"]': { fill: 'blue' } })
请参阅 attr / code>方法参考详细信息：。
2) The joint.shapes.devs.Atomic shape does not automatically do that. You would have to create your own shape and do it there either via foreighObject or programmatically in JavaScript. As a reference for using foreignObject, please see the joint.shapes.basic.TextBlock shape that is defined in this file: https://github.com/DavidDurman/joint/blob/master/plugins/joint.shapes.basic.js.
