Question

我有一个具有data-options属性名称的元素，每个元素都有不同的配置，它不是为便于阅读和易于维护而格式化的json。

<table scoa-table data-options="
responsive:true,
setHeaders:['header1','header2','header3'],
colWidth : 300,
data : {
   "data1" : "value1",
   "data2" : "value2",
   "data3" : "value4",
}`
"></table>

我需要将字符串解析为逗号分隔的值

到目前为止，我有以下内容：

var foo = jQuery("[scoa-table]").attr("data-options"),
    result = foo.split(/,(?![^\[]*\])/gm)

但只能在括号中使用，而不能在括号中使用

这是我的期望

(3) ["responsive:true", 
    "setHeaders:['header1','header2','header3']",
    "colWidth : 300",
    'data : {"data1" : "value1","data2" : "value2","data3" : "value4",}'
   ]

而不是使用逗号，请尝试将“ \ n”换行作为拆分参数：对于您的输入，您可以使用：

var cy = (window.cy = cytoscape({
  container: document.getElementById("cy"),

  boxSelectionEnabled: false,
  autounselectify: true,

  style: [{
      selector: "node",
      css: {
        label: "data(name)", //access the nodes data with "data(...)"
        // label: "data(id)", 
        "text-valign": "center",
        "text-halign": "center",
        height: "60px",
        width: "100px",
        shape: "rectangle",
        "background-color": "data(faveColor)"
      }
    },
    {
      selector: "edge",
      css: {
        "curve-style": "bezier",
        "control-point-step-size": 40,
        "target-arrow-shape": "triangle"
      }
    }
  ],

  elements: {
    nodes: [{
        data: {
          id: "Top",
          faveColor: "#2763c4",
          name: "Steve"
        }
      },
      {
        data: {
          id: "yes",
          faveColor: "#37a32d",
          name: "Larry"
        }
      },
      {
        data: {
          id: "no",
          faveColor: "#2763c4",
          name: "Kiwi"
        }
      },
      {
        data: {
          id: "Third",
          faveColor: "#2763c4",
          name: "Alex"
        }
      },
      {
        data: {
          id: "Fourth",
          faveColor: "#56a9f7",
          name: "Vader"
        }
      }
    ],
    edges: [{
        data: {
          source: "Top",
          target: "yes"
        }
      },
      {
        data: {
          source: "Top",
          target: "no"
        }
      },
      {
        data: {
          source: "no",
          target: "Third"
        }
      },
      {
        data: {
          source: "Third",
          target: "Fourth"
        }
      },
      {
        data: {
          source: "Fourth",
          target: "Third"
        }
      }
    ]
  },
  layout: {
    name: "dagre"
  }
}));

顺便说一句：您可能也需要替换body { font: 14px helvetica neue, helvetica, arial, sans-serif; } #cy { height: 100%; width: 100%; left: 0; top: 0; float: left; position: absolute; }，并在分隔行中使用最后一个逗号，例如：

<html>

<head>
  <meta charset=utf-8 />
  <meta name="viewport" content="user-scalable=no, initial-scale=1.0, minimum-scale=1.0, maximum-scale=1.0, minimal-ui">
  <script src="https://unpkg.com/cytoscape@3.3.0/dist/cytoscape.min.js">
  </script>
  <!-- cyposcape dagre -->
  <script src="https://unpkg.com/dagre@0.7.4/dist/dagre.js"></script>
  <script src="https://cdn.rawgit.com/cytoscape/cytoscape.js-dagre/1.5.0/cytoscape-dagre.js"></script>
</head>

<body>
  <div id="cy"></div>
</body>

</html>

将对象放在对象上并使用JSON.stringify将键和值转换为字符串，然后再将其压入数组

var foo = {
  responsive: true,
  setHeaders: ['header1', 'header2', 'header3'],
  colWidth: 300,
  data: {
    "data1": "value1",
    "data2": "value2",
    "data3": "value4",
  }
}

let arr = [];
for (let keys in foo) {
  arr.push(`${keys}:${JSON.stringify(foo[keys])}`)
}
console.log(arr)

字符串的逗号，但不包含在括号和括号中
