javascript 怎么获取外部文件.js中的数组值.js文件内容

var areaServer=[{"id":"6122","name":"神骑世界","order":"1",
"server":[{"id":"34579","name":"所有区服","order":"0","value":"0"}],
"value":"1"},{"id":"6613","name":"狼烟","order":"1",
"server":[{"id":"37952","name":"烽火万里","order":"0","value":"1001"}],"value":"2"}]

Answer 1

直接用就可以，不如a.js包含
var areaServer=[{"id":"6122","name":"神骑世界","order":"1",
"server":[{"id":"34579","name":"所有区服","order":"0","value":"0"}],
"value":"1"},{"id":"6613","name":"狼烟","order":"1",
"server":[{"id":"37952","name":"烽火万里","order":"0","value":"1001"}],"value":"2"}]；

再b.htm页面，需要先引用js文件，相对路径绝对路径都可以，但是必须是网络路径，而不是本地路径
<script type="text/javascript" src="a.js"></script>
<script type="text/javascript">
alert(areaServer[0].id);
</script>

Answer 2

1楼的回答是正确的
你引入的方式有问题
<script type="text/javascript" src="D:/a.js"></script>是不可以的
应该用url的方式
例如，将js文件放到页面的js子目录下，然后
<script type="text/javascript" src="js/a.js"></script>

Answer 3

<script type=“text/javascript” src="xxx/xxx.js"></script>
src 是你要引入的js 路径和名字。

我知道啊 那么引入进来了后怎么取出.js文件中的数组内容啊？xx.js文件内容只有var areaServer=[{"id":"6122","name":"神骑世界","order":"1","server":[{"id":"34579","name":"所有区服","order":"0","value":"0"}],"value":"1"},{"id":"6613","name":"狼烟","order":"1","server":[{"id":"37952","name":"烽火万里","order":"0","value":"1001"}],"value":"2"}]

直接用就可以了。

怎么直接取出啊？求完整点的代码 我怎么试了好多次取不出来

alert(areaServer[0].name+"的server是："+areaServer[0].server.name);

这样没用啊！按照道理来说也是取不出 应该是areaServer数组未定义
我应该怎么取呢?

src="D:/a.js" 绝对路径是不行的哦。要是相对的路径哦。把你的js　文件放你的工程里。
在引用。
