I'm looking for a way where I can use a JSON as a config file,
我正在寻找一种可以使用JSON作为配置文件的方法,
My JSON config file looks like :
我的JSON配置文件如下所示:
{
'Lang' : 'EN',
'URL' : '/over/dose/app'
}
and I want to get the URL and Lang in the html file using javascript or jQuery. I don't wanna use an asynchronous method like $.getJson
.
我想使用javascript或jQuery获取html文件中的URL和Lang。我不想使用像$ .getJson这样的异步方法。
I want to get the Url and language from JSON file something like :
我想从JSON文件中获取Url和语言:
var url = myjson.URL;
so I can use the var later in so many different functions.
所以我可以在很多不同的函数中使用var。

If you don't want to use an asynchronous call you can always assign a variable to the config object and put the file in the src
of a script tag
如果您不想使用异步调用,您始终可以将一个变量分配给配置对象,并将该文件放在脚本标记的src中
var appConfig={
'Lang' : 'EN',
'URL' : '/over/dose/app'
}
.
。
<script src="/path/to/config.js"></script>
<script> alert(appConfig.URL);</script>
Advantage is immediate loading. Possible disadvantage is it isn't a json file any more, it is regular javascript file in case you are writing to it from server code
优点是立即加载。可能的缺点是它不再是json文件,它是常规的javascript文件,以防你从服务器代码写入它
Of course this also creates a global variable.
当然,这也会创建一个全局变量。

something like
就像是
var cfg = {};
$.ajax({
url: myUrl,
async: false,
success: function(data) {
cfg = JSON.parse(data);
}
});
