Javascript 这个长矩阵可以在代码中拆分为多行吗？

我知道JS中的字符串可以拆分为多行，但是矩阵呢

$('#map').gameMap({map:[[{"tile":"grass_0","object":""},{"tile":"grass_0","object":""},{"tile":"grass_3","object":""}],[{"tile":"grass_0","object":""},{"tile":"grass_3","object":""},{"tile":"grass_0","object":""}],[{"tile":"grass_1","object":""},{"tile":"grass_0","object":""},{"tile":"grass_2","object":""}]],xpos:-1,ypos:-1,mapsize:3});

我的主管喜欢在一个页面上查看代码，而不必滚动查看冗长的行。

可能是这样的：

$('#map').gameMap({map:[[{"tile":"grass_0","object":""},
                         {"tile":"grass_0","object":""},
                         {"tile":"grass_3","object":""}],
                        [{"tile":"grass_0","object":""},
                         {"tile":"grass_3","object":""},
                         {"tile":"grass_0","object":""}],
                        [{"tile":"grass_1","object":""},
                         {"tile":"grass_0","object":""},
                         {"tile":"grass_2","object":""}]],
                   xpos:-1,
                   ypos:-1,
                   mapsize:3});

---

也许是这样的：

$('#map').gameMap({map:[[{"tile":"grass_0","object":""},
                         {"tile":"grass_0","object":""},
                         {"tile":"grass_3","object":""}],
                        [{"tile":"grass_0","object":""},
                         {"tile":"grass_3","object":""},
                         {"tile":"grass_0","object":""}],
                        [{"tile":"grass_1","object":""},
                         {"tile":"grass_0","object":""},
                         {"tile":"grass_2","object":""}]],
                   xpos:-1,
                   ypos:-1,
                   mapsize:3});

您可以使用整理JavaScript代码。这是它的输出：

$('#map').gameMap({
    map: [[{
        "tile": "grass_0",
        "object": ""},
    {
        "tile": "grass_0",
        "object": ""},
    {
        "tile": "grass_3",
        "object": ""}], [{
        "tile": "grass_0",
        "object": ""},
    {
        "tile": "grass_3",
        "object": ""},
    {
        "tile": "grass_0",
        "object": ""}], [{
        "tile": "grass_1",
        "object": ""},
    {
        "tile": "grass_0",
        "object": ""},
    {
        "tile": "grass_2",
        "object": ""}]],
    xpos: -1,
    ypos: -1,
    mapsize: 3
});

    {
        "tile": "grass_0",
        "object": ""},
    {
        "tile": "grass_3",
        "object": ""}], [{
        "tile": "grass_0",
        "object": ""},
    {
        "tile": "grass_3",
        "object": ""},
    {
        "tile": "grass_0",
        "object": ""}], [{
        "tile": "grass_1",
        "object": ""},
    {
        "tile": "grass_0",

    {

        "object": ""}]],
    xpos: -1,
    ypos: -1,

});

当然可以。。。只要你不在一个字符串中间断裂，你也可以把它拆开。

$('#map').gameMap(
      {map:[
         [
           {"tile":"grass_0","object":""},
           {"tile":"grass_0","object":""},
           {"tile":"grass_3","object":""}
         ],
         [
           {"tile":"grass_0","object":""},
           {"tile":"grass_3","object":""},
           {"tile":"grass_0","object":""}
         ],
         [
           {"tile":"grass_1","object":""},
           {"tile":"grass_0","object":""},
           {"tile":"grass_2","object":""}
         ]
     ],
     xpos:-1,
     ypos:-1,
     mapsize:3
     }
);

JavaScript没有矩阵数据结构。这里有一个对象文本（

{map:…}

），它包含一个对象文本数组数组

除此之外，正如其他人所指出的，您当然可以将其拆分为多行，这也为您提供了添加一些合理缩进的机会，这将使其在将来更易于阅读和修改。就我个人而言，我是它的粉丝，我认为它的可读性和（程序员）错误（即缺少逗号）的可能性都最大，同时还有对齐的冒号（

：

）和大量的空白：

$('#map').gameMap(
  { map     : [ [ { "tile" : "grass_0", "object" : "" }
                , { "tile" : "grass_0", "object" : "" }
                , { "tile" : "grass_3", "object" : "" }
                ]
              , [ { "tile" : "grass_0", "object" : "" }
                , { "tile" : "grass_3", "object" : "" }
                , { "tile" : "grass_0", "object" : "" }
                ]
              , [ /* and so on... */
                ]
              ]
  , xpos    : -1
  , ypos    : -1
  , mapsize :  3
  }
);
