javascript – 如何从ajax成功函数返回数据？

在我的前端JavaScript应用程序中,我发出了一个从服务器获取数据的ajax请求.一旦我获得数据,我想将该信息返回给视图.

var view_data;
$.ajax({
    url:"/getDataFromServer.json",
    //async: false,
    type: "POST",
    dataType: "json",
    success:function(response_data_json) {
        view_data = response_data_json.view_data;
        console.log(view_data); //Shows the correct piece of @R_761_4045@ion
        return view_data; // Does not work. Returns empty data
    }
 });

 // return view_data; --> Keeping the return outside of the ajax call works but then I need to make my ajax call synchronous in order for this return clause to be executed after the ajax call fetches data.

我该怎么做？

解决方法:

而不是从成功返回数据：将数据传递给函数.

var view_data;
$.ajax({
    url:"/getDataFromServer.json",
    //async: false,
    type: "POST",
    dataType: "json",
    success:function(response_data_json) {
        view_data = response_data_json.view_data;
        console.log(view_data); //Shows the correct piece of @R_761_4045@ion
        doWork(view_data); // Pass data to a function
    }
 });

function doWork(data)
{
    //perform work here
}
