API文档(http://js.cytoscape.org/#extensions/api)指出cytoscape( type, name, extension )
谁应该注册扩展。它在中起作用,v2.4
但在中不再起作用v2.6
。现在正确的方法是什么?
编辑:这是我的工作
;(function($$){ 'use strict';
var defaults = {
fit: true, // whether to fit the viewport to the graph
padding: 30, // the padding on fit
startAngle: 3/2 * Math.PI, // the position of the first node
counterclockwise: false, // whether the layout should go counterclockwise/anticlockwise (true) or clockwise (false)
minNodeSpacing: 10, // min spacing between outside of nodes (used for radius adjustment)
boundingBox: undefined, // constrain layout bounds; { x1, y1, x2, y2 } or { x1, y1, w, h }
avoidOverlap: true, // prevents node overlap, may overflow boundingBox if not enough space
height: undefined, // height of layout area (overrides container height)
width: undefined, // width of layout area (overrides container width)
concentric: function(node){ // returns numeric value for each node, placing higher nodes in levels towards the centre
return node.degree();
},
levelWidth: function(nodes){ // the variation of concentric values in each level
return nodes.maxDegree() / 4;
},
animate: false, // whether to transition the node positions
animationDuration: 500, // duration of animation in ms if enabled
ready: undefined, // callback on layoutready
stop: undefined // callback on layoutstop
};
function ConcentricLayout( options ){
console.log('INIT');
this.options = $$.util.extend({}, defaults, options);
}
ConcentricLayout.prototype.run = function(){
console.log('RUNNING');
// Run code
};
$$('layout', 'customconcentric', ConcentricLayout);
})( cytoscape );
以及我如何使用它
var cy = cytoscape({
container: document.getElementById('cy'),
boxSelectionEnabled: false,
autounselectify: true,
elements: p,
layout: {
name: 'null',
stop: function() {
cy.elements('node.group').forEach(function( ele ){
var eles = ele.children();
eles.layout({
name: 'customgrid',
fit: false,
avoidOverlapPadding: 0,
columns: 2
});
});
cy.elements('node.machine').forEach(function( ele ){
var elesleft = ele.children('node.mod');
var elesright = ele.children('node.group');
var descendants = elesright.descendants();
if (elesleft.length > 0) {
var relpos = getRelativePositions(descendants);
elesright.forEach(function( ele ){
ele.relativePosition('x', 200);
});
setRelativePositions(relpos, cy);
elesleft.layout({
name: 'customgrid',
fit: false,
avoidOverlapPadding: 0,
columns: 1
});
}
});
cy.elements('node.machine, node.env').layout({
name: 'customconcentric',
fit: true
});
}
}
});
在2.4.9中,我在浏览器的JavaScript控制台中看到了这一点。
cytoscape.layout.custom.js:41 INIT
cytoscape.layout.custom.js:46 RUNNING
对于2.6.2,什么也没有发生。
注册API很好。您所依赖的私有对象不可访问:
this.options = $$.util.extend({}, defaults, options);
如果您希望代码与较新版本兼容,请仅在文档中引用公共API:http : //js.cytoscape.org
使用适当的调试器,例如在Chrome中。当您引用不存在的对象或导致异常时,调试器应向您显示一条错误消息。
