0x01 特别的tree
在安全平台项目里面需要使用tree做一个端口\IP树图并且跟机房一一对应,然后之前了解过前同事在做cmdb的时候用过这个玩意,然后也分享过,就翻下旧的代码,但是,一直没找到 orz。好吧,然后就自己研究下,看看这个玩意到底怎么玩。
0x02 摸索使用
最开始当然是参考下别人写的,看看咋用的。比如像这样:

又或者这样:

但是感觉它们用的方式跟我期待的不太一样,并且对于我来说,扒下来测试的结果不行,可能自己的用法不对吧。。。反正就是各种错误。。用console将结果dump出来,也是个悲剧。
0x03 构建
后来经过折腾,分析javascript的源码以及对方提供的api,折腾出来了。对于我这种读书少的人简直就是一种罪过啊。。。
function d3_dowrite(j_url){
var m = [20, 120, 20, 120],
w = 1280 - m[1] - m[3],
h = 768 - m[0] - m[2],
i = 0,
root;
var tree = d3.layout.tree()
.size([h, w]);
var diagonal = d3.svg.diagonal()
.projection(function(d) { return [d.y, d.x]; });
var vis = d3.select("#tree-container").append("svg:svg")
.attr("width", w + m[1] + m[3])
.attr("height", h + m[0] + m[2])
.append("svg:g")
.attr("transform", "translate(" + m[3] + "," + m[0] + ")");
d3.json(j_url, function(json) {
root = json;
root.x0 = h / 2;
root.y0 = 0;
function toggleAll(d) {
if (d.children) {
d.children.forEach(toggleAll);
toggle(d);
}
}
// Initialize the display to show a few nodes.
root.children.forEach(toggleAll);
for (var i = 0; i<root.children.length; i++){
toggle(root.children[i]);
}
update(root);
});
function update(source) {
var duration = d3.event && d3.event.altKey ? 5000 : 500;
// Compute the new tree layout.
var nodes = tree.nodes(root).reverse();
// Normalize for fixed-depth.
nodes.forEach(function(d) { d.y = d.depth * 180; });
// Update the nodes…
var node = vis.selectAll("g.node")
.data(nodes, function(d) { return d.id || (d.id = ++i); });
// Enter any new nodes at the parent's previous position.
var nodeEnter = node.enter().append("svg:g")
.attr("class", "node")
.attr("transform", function(d) { return "translate(" + source.y0 + "," + source.x0 + ")"; })
.on("click", function(d) { toggle(d); update(d); });
nodeEnter.append("svg:circle")
.attr("r", 1e-6)
.style("fill", function(d) { return d._children ? "lightsteelblue" : "#fff"; });
nodeEnter.append("svg:text")
.attr("x", function(d) { return d.children || d._children ? -10 : 10; })
.attr("dy", ".35em")
.attr("text-anchor", function(d) { return d.children || d._children ? "end" : "start"; })
.text(function(d) { return d.name; })
.style("fill-opacity", 1e-6);
// Transition nodes to their new position.
var nodeUpdate = node.transition()
.duration(duration)
.attr("transform", function(d) { return "translate(" + d.y + "," + d.x + ")"; });
nodeUpdate.select("circle")
.attr("r", 4.5)
.style("fill", function(d) { return d._children ? "lightsteelblue" : "#fff"; });
nodeUpdate.select("text")
.style("fill-opacity", 1);
// Transition exiting nodes to the parent's new position.
var nodeExit = node.exit().transition()
.duration(duration)
.attr("transform", function(d) { return "translate(" + source.y + "," + source.x + ")"; })
.remove();
nodeExit.select("circle")
.attr("r", 1e-6);
nodeExit.select("text")
.style("fill-opacity", 1e-6);
// Update the links…
var link = vis.selectAll("path.link")
.data(tree.links(nodes), function(d) { return d.target.id; });
// Enter any new links at the parent's previous position.
link.enter().insert("svg:path", "g")
.attr("class", "link")
.attr("d", function(d) {
var o = {x: source.x0, y: source.y0};
return diagonal({source: o, target: o});
})
.transition()
.duration(duration)
.attr("d", diagonal);
// Transition links to their new position.
link.transition()
.duration(duration)
.attr("d", diagonal);
// Transition exiting nodes to the parent's new position.
link.exit().transition()
.duration(duration)
.attr("d", function(d) {
var o = {x: source.x, y: source.y};
return diagonal({source: o, target: o});
})
.remove();
// Stash the old positions for transition.
nodes.forEach(function(d) {
d.x0 = d.x;
d.y0 = d.y;
});
}
// Toggle children.
function toggle(d) {
if (d.children) {
d._children = d.children;
d.children = null;
} else {
d.children = d._children;
d._children = null;
}
}
}
用法:
path = window.location.pathname;
if (path == '/index.php/houtai/portscan'){
d3_dowrite('http://scanp.my.com//flare.json');
}
由于我的页面是刷新跳转的,所以我需要判断页面的地址。根据不同的地址,我需要将不同的数据加载。so,就是这样了。。
