问题描述
我有一个小问题:
我使用这个例子(),我修改了
flare.json文件,如下所示:
{
name:flare,
children:[
{
name ,
children:[
{
name:Courses,
children
name:A,size:5731,url: index.html},
{name:Prof. B,size:5731},
{name:Prof. C,size:5731}
]
},
{
name:E& E,
children:[
{name: D,size:5731},
{name:Prof. E,size:5731},
{name:Prof.F :5731},
{name:Prof. G,size:5731},
{name:Prof. H,size:5731}
]
},
{
name:IBSS,
children:[
{name: I,size:5731},
{name: J,size:5731},
{name: K,size:5731}
]
},
{name:,size:0},
{
name :E-Gov,
children:[
{name: L,size:5731},
{name: M,size:5731},
{name: N,size:5731}
]
},
{
name:Muki,
children:[
{name:教授O,size:5731},
{name: P,size:5731},
{name: Q,size:5731},
{name: V,size:5731}
]
},
{name:Schedule,size:5731} News,size:5731},
{name:Events,size:5731},
{name:Search,size:5731}
{name:,size:0}
]
},
{name:,size:0} b]
},
如果我点击Prof.A,我得到我的下一个html页面
我的问题是,我可以点击Prof.A,即使我没有放大在这个泡沫。我只是想要能够点击它,当我放大它,并且标签是可读的。
我试图修复缩放功能,但似乎没有任何效果。

我无法取得任何进展似乎无效请帮助我!
让我在@ Elijah的答案上展开一些:
首先,位从css:
.node - root,
.node - leaf {
指针事件:all;
}
,以便更好地控制指针事件。
接下来,我们向节点添加一些额外的类,以便我们更容易地访问这些类: .attr(class,function(d){return'depth'+ d.depth +''+
(d.parent?d.children?node:node node--因此,每个节点都有一些额外的节点,每个节点都有一个节点,每个节点都有一个节点 - 节点节点 - 根节点);})
.depth4 。
现在我们可以直接与节点通话,并根据需要添加/删除指针事件。
为此,和方便,我们添加一个新的函数:
function adjustPointerEvents(depth){
d3.selectAll '.node')。attr('pointer-events','none');
d3.select('。node - root')。attr('pointer-events','all')
d3.selectAll('。depth'+(depth + 1))。attr('pointer-events','all');
}
(首先我们删除所有事件,然后将事件添加到node- root back(为了能够缩小),然后我们添加'下一级'的事件))
在init上,我们称之为2级:
adjustPointerEvents(2);
顺便说一下:你有一个额外的层('Kommunikation und Umwelt' 'Courses'),我将微调给你...
我们必须确保我们在上点击
:
function clickFct(d,i){
adjustPointerEvents(d.depth);
...
我们都设置好了。
以下是更新的jsfiddle:
如上所述,仍然需要一些微调,但我希望我提供一些更多的指针。
I have a little problem here:
I'm working with this example (http://bl.ocks.org/mbostock/7607535) and I modified theflare.json file like this:

{
"name": "Courses",
"children": [

{"name": "Prof. C", "size": 5731}
]
},

If I click on Prof.A, I get my next html page.My problem is that I can click on Prof.A even when I haven't zoomed in on this bubble. I just want to be able to click on it when I have zoomed on it and the label is readable.
I tried to "fix" the zoom functions, but nothing seems to work.

I cant make any progress nothing seems to work please help me!
Let me expand a bit on @Elijah's answer:
First, I'd remove the following bit from the css:
.node--root,
.node--leaf {
pointer-events: all;
}
in order to get more control over the pointer-events.
Next, we add some additional class to the nodes so that we can access these more easily:
.attr("class", function(d) { return 'depth' + d.depth + ' ' +
(d.parent ? d.children ? "node" : "node node--leaf" : "node node--root"); })
Accordingly, every node has some additional class, like .depth4
.
Now we can talk to the nodes, directly and add/remove the pointer-events as needed.
For that, and convenience, we add a new function:
function adjustPointerEvents(depth) {
d3.selectAll('.node').attr('pointer-events', 'none');
d3.select('.node--root').attr('pointer-events', 'all');
d3.selectAll('.depth' + (depth + 1)).attr('pointer-events', 'all');
}
(first we remove all events, then we add the events to the node-root back (to be able to zoom out), and then we add the events for the 'next' level))
On init, we call that at level 2:
adjustPointerEvents(2);
By the way: you have some sort of an additional layer there ('Kommunikation und Umwelt' and then 'Courses'), I leave the fine tuning to you...
And we have to make sure we call that on click
:
function clickFct(d,i) {
adjustPointerEvents(d.depth);
...
And we're all set.
Here's the updated jsfiddle: Fiddle
As mentioned above, some fine tuning is still needed, but I hope I provided some more pointers.
这篇关于如何实现,泡沫只有可点击如果完全缩放d3js的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持!
