jtopo树结构方法积累 jtopo树结构方法积累

1、计算最外层最大节点个数：

function getMaxLeafCnt(data) { var maxcnt = 0; //本身 var children = data.children == undefined ? new Array() : data.children; if (children.length > 0) { for (var i = 0; i < children.length; i++) { var f = children[i]; if (f.children == undefined) { maxcnt++; } else { maxcnt += getMaxLeafCnt(f); } } } return maxcnt; }

2、树形布局，无须自己计算位置：

// 树形布局 scene.doLayout(JTopo.layout.TreeLayout('down', 30, 107));

3、设置警告：

setInterval(function () { for (var i = 0; i < nodeAlarms.length; i++) { var s = nodeAlarms[i]; if (s.alarm == '二级告警') { s.alarm = null; } else { s.alarm = '二级告警' } } }, 600);
