本文介绍了D3 Force Directed Graph:为什么标志不出现?的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
状况:
每个节点
都应该有相应的标志,情况并非如此。
Each node
should have it's corresponding flag on it, that is not the case.
代码:
body {
font-family: Lato;
background-color: #F5F5F5;
}
.title {
margin-top: 30px;
margin-bottom: 30px;
}
#results {
text-align: center;
}
#results div {
margin-top: 15px;
}
#results {
background-color: white;
margin: auto;
width: 1200px;
padding: 40px;
box-shadow: 2px 2px 2px black;
}

推荐答案
对代码进行了一些更改,现在似乎正在运行。
A few changes are made to the code and seem to be working now.
- 包含div的位置属性flags和flag类设置为绝对值。
-
< img>
标记已附加两次。删除了额外的代码。 - 错误提示 - 在dragstart中将
sim
更改为模拟
和dragend方法。 -
flags
div不在svg内。因此,从result.select(#flags)
更改为d3.select(#flags)
- Position attribute of the div containing flags and flag class is set to absolute.
<img>
tag was appended twice. Removed extra code.- Typo error - Change
sim
tosimulation
in dragstart and dragend methods. flags
div is not inside svg. So change fromresult.select("#flags")
tod3.select("#flags")
等。
