如何使用JavaScript编写多维数组，就像php一样，我可以在其中循环并根据键值搜索它。 

        var domainme = array( 
                [0] array (
                        "domain" => "one.com",
                        "database" => "one",
                        "api" => "one.php"
                    )               
                [1] array (
                        "domain" => "two.com",
                        "database" => "two",
                        "api" => "two.php"
                    )               
                [2] array (
                        "domain" => "three.com",
                        "database" => "three",
                        "api" => "three.php"
                    )
JavaScript区分

数组和对象（尽管数组也是对象）。你会这样写你所拥有的：

var domainme = [
    {domain: "one.com", database: "one", api: "one.php"},
    {domain: "two.com", database: "two", api: "two.php"},
    {domain: "three.com", database: "three", api: "three.php"}
];

[]定义数组文本，{}定义对象文本。

你需要使用一个对象数组。

喜欢：

var domainme = [{
  "domain": "one.com",
  "database": "one",
  "api": "one.php"
}, {
  "domain": "two.com",
  "database": "two",
  "api": "two.php"
}, {
  "domain": "three.com",
  "database": "three",
  "api": "three.php"
}]

要获取一个值，您可以执行以下操作：

domainme[0]["domain"] // get : 'one.com'
//or 
domainme[0].domain // get : 'one.com'
