页面准备就绪时，将数据从本地文件存储到变量 [英] Store data from local file to variable when the page is ready

问题描述

var persons;
        $(function () {
            $.getJSON("person.json", function(data){ persons = JSON.stringify(data); 
                console.log("This is inside: "+ persons); });
                console.log("This is outside" + persons);
            }
            getJSONData();
        });

i想要将本地文件（person.json）中的数据存储到开头的变量中。但结果是：

i want to get and store data from local file(person.json) into a variable at the beginning. But the result is:

This is outside: undefined
This is inside: [{"name":"user1","gender":"male"},{"name":"user2"},{"gender":"female"}]

我怎么能在一开始就将数据存储到变量中？



我尝试过：

So how can i get and store data into variable at the very beginning?

What I have tried:

var persons;
    function getJSONData() {
        $.getJSON("person.json", function(data){ persons = JSON.stringify(data); 
        console.log("This is inside: "+ persons); });
    }
    getJSONData();
    $(function () {
        console.log("This is outside: " + persons);
    });

我试过这个，但结果是一样的......

I have tried this, but the result is same...

推荐答案

（ function （）{

.getJSON（ person.json， function （data）{persons = JSON .stringify（data）;
< span class =code-sdkkeyword> console .log（ 这里面是： +人）;}）;
console .log（ 这是 +人）之外;
}
getJSONData（）;
}）;

.getJSON("person.json", function(data){ persons = JSON.stringify(data); console.log("This is inside: "+ persons); }); console.log("This is outside" + persons); } getJSONData(); });
