我正在尝试通过 d3plus.js 构建一个小型应用程序。目的是使用网络可视化来显示代表 pdf 文件的一系列节点。单击节点时，应该会出现一个显示 pdf 的窗口。

我想出了如何使用 window.open() 函数，如果我将路径直接写入 window.open() 函数（fx“docs/somepdf.pdf”），它就可以工作。

我现在的问题是将路径字符串从 sample_data 传递给 window.open 函数。

谁能告诉我我在这里做错了什么？

<script src="//d3plus.org/js/d3.js"></script>
<script src="//d3plus.org/js/d3plus.js"></script>

<div id="viz"></div>

<script>
  // create list of node positions
  var sample_data = [
    {"name": "alpha", "size": 10, "path": "docs/Tan - 1999 - Text mining The state of the art and the challeng.pdf"},
    {"name": "beta", "size": 12, "path": ""},
    {"name": "gamma", "size": 30, "path": ""},
    {"name": "delta", "size": 26, "path": ""},
    {"name": "epsilon", "size": 12, "path": ""},
    {"name": "zeta", "size": 26, "path": ""},
    {"name": "theta", "size": 11, "path": ""},
    {"name": "eta", "size": 24, "path": ""}
  ]
  var connections = [
    {"source": "alpha", "target": "beta"},
    {"source": "alpha", "target": "gamma"},
    {"source": "beta", "target": "delta"},
    {"source": "beta", "target": "epsilon"},
    {"source": "zeta", "target": "gamma"},
    {"source": "theta", "target": "gamma"},
    {"source": "eta", "target": "gamma"}
  ]
  // instantiate d3plus
  var visualization = d3plus.viz()
    .container("#viz")
    .type("network")
    .edges(connections)
    .size("size")
    .id("name")
    .tooltip(["name", "size"]).mouse({                
      "move": false,                        // key will also take custom function
      "click": function(){window.open("path", '_blank', 'fullscreen=yes')}    
    })
    .draw()
</script>

问题是您将“路径”作为字符串而不是节点的属性提供。

尝试将您的mouse方法更改为：

.mouse({                
  "move": false,
  "click": function(node){window.open(node.path, '_blank', 'fullscreen=yes')}    
})

看看类似的工作示例：http: //jsfiddle.net/v1fvhpvx/14/
