|
2、执行时间
1 2
| console.time(); console.timeEnd();
|
3、内存占用
1 2 3 4 5 6 7
| memory:{ jsHeapSizeLimit: 2190000000 totalJSHeapSize: 11900000 usedJSHeapSize: 10000000 }
|
4、提示位置
1 2 3 4
| force.on("start", function () { console.trace("布局开始"); })
|
5、统计执行次数
1 2 3 4 5 6 7 8 9 10
| force.on("start", function () { console.trace("布局开始"); }) .on("end", function () { console.log("布局结束"); }) .on('tick', function () { console.count("COUNT"); }) .start()
|
1
| 力学图算法一共进行了 298次迭代 最终布局完成 # console.count("COUNT");该方法对性能影响较大
